Description

A split-type double-headed sputum suction tube

technical field

The utility model relates to an auxiliary appliance for respiratory care, in particular to a split-type double-head sputum suction tube.

Background technique

Sputum suction is a method to suck out the secretions of the respiratory tract through the nasal cavity and oral airway to keep the respiratory tract unobstructed and prevent aspiration pneumonia, atelectasis, suffocation and other complications. Patients with a lot of fluid and the possibility of suffocation, patients who need intratracheal administration, injection of contrast medium or dilution of sputum, etc.

When suctioning, you need to use negative pressure equipment and a suction tube. Negative pressure equipment is a device that can generate a strong negative pressure and has a collection chamber in it. When sucking sputum, insert the sputum suction tube into the patient's nasal cavity or oral airway, activate the negative pressure device, and the sputum is sucked into the collection cavity through the sputum suction tube under the action of negative pressure suction.

The main problem existing in the use of the current sputum suction tube is that the current sputum suction tube is a single tube, and when used by the same patient, it is sometimes necessary to alternately suck sputum through the nasal cavity and the oral airway. The operation is very unhygienic, and it is troublesome to clean up during the switching process, which will bring sensory and psychological discomfort to the patient.

detailed description

According to the above-mentioned technical scheme, as shown in Fig. 1 to Fig. 4, the utility model provides a split-type double-head sputum suction tube, which includes a total suction tube 5, and a soft connecting tube 6 is connected to the total suction tube 5. Both ends of the tube 6 are detachably provided with a nasal suction tube 7 and an oral suction tube 1 respectively, and top suction holes 8 and side suction holes 9 are distributed on the top and side surfaces of the nasal suction tube 7 and the oral suction tube 1 .

The sputum suction tube of the utility model has a split structure, that is, the sputum suction tube adopts two tube bodies to respectively suck sputum from the nasal cavity and the oral airway, and the two can be carried out simultaneously or sequentially. With such a suction method, the tube body in contact with the nasal cavity and the oral cavity is separated, which avoids cross-contamination. In this scheme, a flexible connecting pipe 6 is provided at the end of the total suction pipe 5 connected to the negative pressure machine, and the connecting pipe 6 connects the nasal suction pipe 7 and the mouth suction pipe 1. The connecting pipe 6 is a flexible pipe, so that the mouth suction pipe 1 and the nasal suction pipe 7 can be relatively separated without affecting each other. Top suction hole 8 and side suction hole 9 are respectively arranged on the end and the side of nasal suction pipe 7, and top suction hole 8 is provided with one, and side suction hole 9 can be provided with a plurality of, can fully suck the mucus in airway, nasal cavity like this. The top suction hole 8 and the side suction hole 9 on the mouth suction pipe 1 are arranged in the same way as the nasal suction pipe 7 .

As shown in Figure 1, it can be seen that the ends of the nasal suction pipe 7 and the oral suction pipe 1 are blunt circular structures; the blunt circular structure means that the ends of the nasal suction pipe 7 and the oral suction pipe 1 are spherical, and such a structure is advantageous The tubular body is carried out in the oral cavity and nasal cavity and is in contact with the internal structure without causing damage to the internal tissue. Nasal suction pipe 7 is longer than oral suction pipe 1, and oral suction pipe 1 is thicker than nasal suction pipe 7;

The bottom end of the mouth suction pipe 1 is connected with a butt joint pipe 2 with a smaller diameter than the mouth suction pipe 1 , and the lower end of the nasal suction pipe 7 and the butt joint pipe 2 are respectively connected with the two ends of the connection pipe 6 . Because the mouth suction pipe 1 has a large diameter and is a disposable product, versatility and convenience of connection need to be considered. Butt joint pipe 2 is provided for this reason, and the pipe diameter of butt joint pipe 2 and connecting pipe 6 is similar, and the setting of butt joint pipe 2 can facilitate docking.

Regarding the specific connection mode of the nasal suction tube 7, the mouth suction tube 1 and the connecting tube 6, taking the nasal suction tube 7 as an example, as shown in Figure 2 and Figure 3:

The bottom end of the nasal suction tube 7 is connected with an intubation tube 10 with a diameter smaller than that of the nasal suction tube 7 . The intubation tube 10 is inserted into the end of the connecting tube 6 , and a snap ring 13 is arranged in the end of the connecting tube 6 . Considering the convenience of use, the nasal suction tube 7 and the connecting pipe 6 are connected in the form of plugging and unplugging. Specifically, there is a cannula 10 at the end of the nasal suction tube 7 , and the cannula 10 has a smaller diameter and can be inserted into the connecting tube 6 . There is a snap ring 13 inside the connecting pipe 6, which is a ring structure arranged around the inner wall of the connecting pipe 6, which plays a role in increasing friction and can make the intubation tube 10 more tightly fixed in the connecting pipe 6.

In order to reinforce the connection, a shrapnel 11 is symmetrically arranged on the outer wall of the bottom end of the nasal suction tube 7, and a bayonet 12 is provided on the shrapnel 11, and a block 3 matching the bayonet 12 is arranged on the outer wall of the connecting pipe 6 end. The elastic piece 11 can be set as an arc-shaped piece, which adapts to the external shape of the nasal suction tube 7 and fits better. After the nasal suction tube 7 is docked with the connecting tube 6, the block 3 is also stuck in the bayonet 12, thereby ensuring a tight connection. After the nasal suction pipe 7 is used up, the shrapnel 11 is opened first to disengage the bayonet 12 from the block 3, and then the nasal suction pipe 7 is pulled out. The connection form between the mouth suction pipe 1 and the connecting pipe 6 is the same as that of the nasal suction pipe 7 , the difference is that the intubation tube 10 and the elastic piece 11 of the mouth suction pipe 1 are arranged on the butt joint 2 .

As shown in Fig. 1, Fig. 3, Fig. 4(a) and Fig. 4(b), sputum suction needs to be sucked separately. For this reason, the joints of nasal suction pipe 7, mouth suction pipe 1 and connecting pipe 6 are all provided There is a regulating valve 4; the regulating valve 4 can not only close the pipe body where it is located, but also adjust the strength of negative pressure suction to better meet the actual suction needs.

The structure of a regulating valve 4 is shown in Figure 4. The regulating valve 4 includes an upper blocking piece 41 and a lower blocking piece 45 arranged at intervals inside the connecting pipe 6. Both the upper blocking piece 41 and the lower blocking piece 45 are provided with through holes. 42, a rotating ball 44 with a central hole 46 is installed between the upper blocking piece 41 and the lower blocking piece 45, and a knob 43 connected with the rotating ball 44 is provided through the side wall of the connecting pipe 6. The rotating ball 44 rotates in the cavity under the control of the knob 43. When the central hole 46 of the rotating ball 44 is staggered from the through hole 42, the internal passage of the connecting pipe 6 is temporarily blocked, and the suction pipe connected to the connecting pipe 6 at this end is temporarily blocked. It is in a closed state without suction; and when the central hole 46 is docked with the through hole 42, the internal airflow can pass through the central hole 46 and the through hole 42, and the sputum suction operation can be performed at this time. The central hole 46 and the through hole 42 are slightly staggered, and the strength of attraction can be adjusted according to the degree of staggering.
