The present invention provides a conventional sampling device based on extrusion type collection. Please refer to Figure 1. It includes a sampling tube 100 and a collection film 200. The top of the sampling tube 100 has an opening, and the collection film 200 is disposed on the top of the sampling tube 100. On the side of the opening, the collection film 200 is shrunk at a position adjacent to the sampling tube 100 before use, for example: around the opening of the sampling tube 100, outside the bottle body of the sampling tube 100, or inside the sampling tube 100. The shrunk collection film 200 is unfolded during use. , forming a collection channel outside the opening.

The first embodiment is shown in Figure 2. The principle of the sampling device of this embodiment is explained with the aid of a toilet. First, the collection film 200 is a funnel-shaped plastic film, so that the bottom of the collection film 200 has a narrow opening with a narrow opening size. It is adapted to the opening of the sampling tube 100, and has a wide opening at the top. The wide opening is adapted to the size of the toilet mouth, and then the narrow opening is directly connected to the opening of the sampling tube 100 (specifically, it can be bonded to the opening through glue), and The wide-mouth side is shrunk by folding or rolling at a position adjacent to the sampling tube 100. When in use, the shrunken collection film 200 is unfolded, and after unfolding, the wide-mouth side of the collection film 200 is placed on the toilet mouth. Here It should be noted that the sampling tube 100 needs to be placed in the toilet, but the sampling tube 100 cannot be allowed to contact the water in the toilet. At this time, it is necessary to control the length of the collection film 200 at the toilet mouth to ensure that the sampling tube 100 does not will come into contact with water. After everything is ready, the collection film 200 will form a collection channel in the toilet, and this collection channel will go straight into the sampling tube 100. Personnel who perform regular stool collection can defecate normally on the toilet. , the discharged stool is collected by the collection film 200, so that personnel do not need to use a stool spoon to remove stool in the toilet, but can directly lift the collection film 200, thereby avoiding contact between stool and water in the toilet, and also reducing the amount of water in the toilet. discomfort caused by personnel.

However, since the opening of the sampling tube 100 is small, it is necessary to squeeze the stool in the collection channel into the sampling tube 100 through the collection film 200 to complete the collection of stool. After completion, the excess stool is wrapped with the collection film 200 , and then tear off the collection film 200 and throw it into the designated trash can. The sampling tube 100 is placed in the designated position, waiting for the staff to detect it.

Preferably, as shown in Figure 3, a tube outer tightening portion 210 is provided on the outer edge of the wide mouth. A common tube outer tightening portion 210 is an elastic cord, elastic band or other elastic component, so that the film 200 can be collected Stably fits over the toilet mouth.

Second embodiment, see Figures 3 to 6. First, in Figures 3 and 4, a coating film 220 is provided on the narrow opening side of the collection film 200. As shown in Figure 5, the coating film 220 is made of The collection film 200 is a cylindrical plastic film extending from the narrow opening side (that is to say, the coating film 220 and the collection film 200 are integrally connected). The end C of the coating film 220 is directly connected to the inner wall of the sampling tube 100 (specifically can be bonded to the inner wall of the sampling tube 100 by glue). To facilitate understanding, the layout direction of the coating film 220 is shown in Figure 9 (only the direction of the coating film 220 is limited, and the actual thickness of the coating film 220 is not considered). Starting from the end C of the coating film 220, lay it upward along the inner wall of the sampling tube 100, fold it outward after reaching the opening, then lay it downward along the outer wall of the sampling tube 100, and then fold it upward to complete a stacking, in which:

The coating film 220 arranged upward along the inner wall of the sampling tube 100 is hereinafter referred to as the inner coating layer 220a;

The coating film 220 stacked on the outer wall of the sampling tube 100 is hereinafter referred to as the tube outer coating layer 220b;

Moreover, part M in FIG. 9 shows one stacking situation, while part N in FIG. 9 shows two stacking situations. The number of stacking times is determined based on the actual length of the outer cladding layer 220b of the tube. , but at least once.

In the first embodiment, the radius of the coating film 220 is slightly smaller than the outer diameter of the sampling tube 100, and the coating film 220 itself has a certain elasticity, so that the outer coating layer 220b covering the sampling tube 100 can The collection film 200 is connected to the sampling tube 100, as shown in Figure 10. When stool (that is, the shaded part in the collection film 200 in Figure 10) accumulates on the opening of the sampling tube 100, a part of the pressure F1 acts on the sampling tube 100, There is also part of the pressure F2, F2´ acting on the collection membrane 200 (since this part of the pressure has little impact on the connection relationship between the tube outer coating 220b and the sampling tube 100, it can be ignored). At the same time, the pressure F1 plus the sampling The gravity of the tube 100 itself and the gravity of stool falling into the inside of the sampling tube 100 form a resultant force F, and the tube outer coating 220b has a certain coating force, so the sampling tube 100 is in contact with the outer wall of the sampling tube 100. Friction forces f and f´ are formed between 220b. The friction forces f and f´ are greater than the resultant force F. Therefore, the effect of the resultant force F is overcome by the friction forces f and f´ and will not be transmitted to the end C, thus preventing the end C from being It is separated from the inner wall of the sampling tube 100 under the action of the resultant force F.

When sampling, squeeze the stool in the collection channel into the sampling tube 100, and use the sampling tube 100 for sampling. The excess stool in the collection channel can be processed as follows: See Figure 11. First, you can manually pull down the sampling tube 100 to make the stacked The outer coating layer 220b of the tube is unfolded to obtain the state ① in Figure 11, thus forming a part of the empty film at the bottom of the collection film 200. This part of the film is tied up to obtain the state ② in Figure 11, and then the collection film is The empty film at the top of the film 200 is also tied up to obtain the state ③ in Figure 11. This completes the sealing of the stool in the collection channel, and then the end of the coating layer 220a in the tube is torn off to obtain the state ④ in Figure 11. , at this time, the film wrapping the stool can be thrown into the trash can, and under the protection of the inner coating layer 220a of the tube, the stool squeezed into the sampling tube 100 will not adhere to the inner wall of the sampling tube 100 near the opening. The inner wall adjacent to the opening of the subsequent sampling tube 100 is made cleaner.

In the second embodiment, as shown in Figure 3, perforations 100A are provided on the wall of the sampling tube 100 corresponding to the connection between the end of the coating film 220 and the inner wall of the sampling tube 100. Here, multiple perforations 100A are provided in an annular array. In Figure 4, an in-tube tightening portion 230 is provided at the edge of the end of the coating film 220. A common in-tube tightening portion 230 is an elastic cord, elastic band or other elastic component. The periphery of the end of the coating film 220 corresponds to the perforation 100A. A connector 240 is provided. As shown in FIGS. 6 and 12 , the connector 240 passes through the perforation 100A to connect the inner pipe cladding layer 220 a and the innermost pipe outer cladding layer 220 b, thus forming two connections. points, these two connection points are respectively: the first connection point a formed by connecting the connecting body 240 and the pipe inner cladding layer 220a, and the second connection point b formed by connecting the connecting body 240 and the innermost pipe outer cladding layer 220b. , at this time, the tightening part 230 in the tube forms a tensile force F3, and the connector 240 forms a tensile force F4. Under the action of the tensile force F4, the inner cladding layer 220a and the outer cladding layer 220b of the tube are close to each other, so that the inside of the tube close to the inner wall of the sampling tube 100 The coating layer 220a can fit the inner wall of the sampling tube 100. At the same time, the outer coating layer 220b close to the outer wall of the sampling tube 100 can also fit the outer wall of the sampling tube 100.

When in use, manually pull up the collection film 200 to expand the tube outer coating 220b to the second connection point b, that is, the state shown in Figure 13, and then pull hard to tear off the connector 240. At this time, the first connection Point a and the second connection point b are separated, and the tensile force F4 no longer exists, and the tightening part 230 in the tube will shrink. Driven by the tightening part 230 in the tube, the coating layer 220a in the tube will retract to collect the The narrow opening side of the film 200 is closed, which is more convenient than the tying/tying method, and when the connector 240 is torn off, the inner coating layer 220a of the pipe and the outer coating layer 220b of the pipe behind the second connection point b can be easily After the sampling tube 100 is detached, the end edge of the tightening part 230 in the tube after detachment will be more complete, and there will be no torn fracture marks.

Further, the radius of the coating film 220 is slightly larger than the outer diameter of the sampling tube 100, as shown in Figure 7. At this time, the outer coating layer 220b of the tube can cover the sampling tube 100, and a pressure plate is provided outside the sampling tube 100. 300, the bottom end of the pressure plate 300 is fixedly connected to the wall of the sampling pipe 100, and the other end is separated from the sampling pipe 100, and this end is pressed on the outer coating 220b of the pipe under its own elastic force, so that the outer coating 220b of the pipe is The pressure plate 300 is wrapped outside the sampling pipe 100 under the pressure of the end of the sampling pipe 100 , so that gravity will not act on the connection between the end of the inner coating layer 220 a and the inner wall of the sampling pipe 100 .

Preferably, as shown in FIG. 7 , the pressing plate 300 is externally arched to form a receiving space outside the sampling tube 100 , so that the collection film 200 can be shrunk within the pressing plate 300 , and is protected by the pressing plate 300 . Under the pressure from the end of the sampling tube 100, the unfolded length of the collection film 200 can be controlled, thus effectively preventing the sampling tube 100 from contacting the water in the toilet.

Furthermore, as shown in FIG. 8 , the side of the perforation 100A close to the outer coating 220 b of the pipe is expanded, and a protrusion 110 is provided in the space formed by the expansion. As shown in FIG. 14 , through the outer coating of the pipe The layer 220b is pulled downward (that is, the side where the second connection point b of the connector 240 is located moves downward in the direction indicated by the arrow), causing the connector 240 to approach and contact the thorn 110, and the connector 240 is punctured under the action of the thorn 110. , so that its strength is reduced, and then under the action of the tightening part 230 in the pipe, the connecting body 240 is pulled off, so that the connecting body 240 can be disconnected without exerting a large force, so as to protect the coating layer inside the pipe 220a and the pipe outer cladding 220b (because the greater the force exerted on the pipe outer cladding 220b, the greater the pulling force on the pipe inner cladding 220a and the pipe outer cladding 220b, and the easier it is to destroyed).

In addition, continuing to refer to FIG. 8 , the protrusion 110 is located on the bottom side of the connecting body 240 , and the end of the pressing plate 300 separated from the sampling tube 100 is disposed adjacent to the top side of the connecting body 240 . Under the obstruction of the outer coating layer 220 b of the tube, the pressing plate 300 is 300 is separated from the end of the sampling tube 100 and cannot be pressed into the space formed by the expansion of the perforation 100A. As the outer coating layer 220b of the tube expands, the space formed by the expansion of the perforation 100A is exposed. At this time, the pressure plate 300 is separated from the end of the sampling tube 100. The end is pressed into the space formed by the expansion, and then the connecting body 240 is squeezed to make it contact with the spur 110, which will be more convenient.

Preferably, the pipe outer cladding 220b is stacked only once to form the innermost pipe outer cladding 220b and the next innermost pipe outer cladding 220b, and the next innermost pipe outer cladding 220b is attached to A glue coating is provided on one side of the innermost pipe outer cladding 220b, so that the unfolded pipe outer cladding 220b can be bonded to the unfolded innermost pipe outer cladding 220b through the glue coating. together to improve the narrow opening sealing effect of the collection film 200 .
