Description

{THE OXYGEN VESSEL FIXING APPARATUS}

The present invention relates to an oxygen cylinder fixing device, and more specifically, to an oxygen cylinder fixing device that can be fixed to various frames such as a wheelchair, a bed, and an IV holder without restriction.

Oxygen therapy is very important for patients with hypoxia who need oxygen supply. When the oxygen saturation (SPO2) is over 95%, it is usually considered to be in the normal range, and when it is between 90 and 95%, it is considered to be in a state of caution for hypoxia. When it is below 90%, it can become a state of hypoxia and become a critical condition where breathing is difficult. In wards, emergency rooms, and outpatient clinics, patients who need oxygen therapy use wall-type oxygen supplied from a medical gas central supply unit, and when movement is necessary, a portable type O2 tank is also used. Portable oxygen tanks are used by mounting them on a separate holder or cart due to size and weight restrictions.

In particular, oxygen tank hangers for wheelchairs or IV poles are widely used in hospitals. In this case, a separate fixing device is required. However, the frames for fixing oxygen tanks to wheelchairs or IV poles extend in different directions relative to the ground. In the case of the prior art, there are cases where installation is impossible depending on the direction of extension of the frame. In other words, the oxygen tank fixing device according to the prior art has a limitation that whether it is fixed or not varies depending on the frame.

Hereinafter, an oxygen container fixing device (1) according to one embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view schematically illustrating an oxygen container fixing device (1) according to one embodiment of the present invention, FIG. 2 is a drawing schematically illustrating a clamp module (20) illustrated in FIG. 1, and FIG. 3 is a drawing schematically illustrating one embodiment of a fixing module (30) illustrated in FIG. 1.

Referring to FIGS. 1 to 3, an oxygen container fixing device (1) according to an embodiment of the present invention includes a support module (10), a clamp module (20), and a fixing module (30). The support module (10) includes a support portion (100) and a support shaft (110). The support portion (100) supports an oxygen container (2). The support portion (100) is movably connected to the support shaft (110). The support shaft (110) is connected to the support portion (100). The support shaft (110) may extend in one direction and have a predetermined length.

In one embodiment, the support member (100) may include an upper frame (102) and a lower frame (103). The upper frame (102) may be connected to the support shaft (110) so as to be movable along the longitudinal direction of the support shaft (110). The upper frame (102) may support between the upper and lower ends of the oxygen container (2). The lower frame (103) is spaced apart from the upper frame (102) in the longitudinal direction of the support shaft (110) and connected to the support shaft (110). The lower frame (103) may support the lower end of the oxygen container (2).

The clamp module (20) fixes the support module (10) to a separate frame (not shown). The frame may extend along a vertical direction (L2) with respect to the ground. In addition, the frame may extend along a horizontal direction (L1) with respect to the ground. That is, the frame may be a vertically extended IV frame. In addition, the frame may be a horizontally extended armrest of a wheelchair. The clamp modules (20) may be arranged in plurality. The plurality of clamp modules (20) may be arranged spaced apart from each other along the longitudinal direction of the support shaft (110).

The clamp module (20) is rotatably connected to the support shaft (110) through the rotating structure (220). Therefore, the clamp module (20) can be coupled to the frame by rotating along the extension direction of the frame. For example, in the case of a vertical frame, the clamp module (20) can be coupled to the frame by rotating 90 degrees. In addition, in the case of a horizontal frame, the clamp module (20) can be coupled to the frame by rotating 90 degrees in the opposite direction. Certain patients carry not only an oxygen tank for oxygen therapy, but also a drainage bag, a drainage hanger, a pole, etc. Therefore, many medical supplies are required, and there are many restrictions on movement. In the case of the present invention, the clamp module (20) is rotatable, so that the oxygen tank fixing device (1) can be fixed to a vertical frame or a horizontal frame as appropriate for the situation.

In one embodiment, the clamp module (20) includes a clamp body (200) and a tightening member (210). The clamp body (200) has a receiving groove (H1). An IV frame or an armrest of a wheelchair, etc., can be inserted into the receiving groove (H1) of the clamp body (200). The receiving groove (H1) also rotates along with the rotation of the clamp module (20). Accordingly, the frame (not shown) can penetrate the clamp module (20) in a vertical or horizontal direction. The tightening member (210) can be fastened to the clamp body (200) in a bolting manner. The tightening member (210) includes a sealing pad (211). When the sealing member (210) rotates in one direction, the sealing pad (211) can be in close contact with the frame (not shown). When the joint part (210) rotates in the other direction, the sealing pad (211) can move away from the frame (not shown).

The fixed module (30) may further include a first link (301), a second link (302), a push lever (303), and a return spring (304). The first link (301) is connected to the support member (100). The second link (302) is connected to the first link (301) by a hinge shaft (A). The fixed pin (300) is arranged on the second link (301). The push lever (303) is connected to the second link (302). The return spring (304) provides elasticity to the second link (302).

The push lever (303) rotates the second link (302) in one direction. The return spring (304) provides elasticity to the second link (302) to rotate the second link (302) in the other direction with respect to the hinge axis (A). The fixed pin (300) rotates together with the second link (302). The fixed pin (300) is inserted into a stop hole (111) arranged in the support shaft (110) or removed from the stop hole (111) according to the rotation.

FIG. 4 is a drawing schematically illustrating a stopper projection (131) according to one embodiment of the present invention.

Referring to FIGS. 1 and 4, the support module (10) may further include a stopper projection (131). The stopper projection (131) protrudes from the support shaft (110). The stopper projection (131) may support the oxygen container (2) to prevent the flow of the oxygen container (2). The stopper projection (131) may have an inclined surface (S1). The oxygen container (2) may include a cylindrical body portion (B), an inclined portion (C) whose outer diameter gradually decreases from the body portion (B), and a nozzle (I). The inclined surface (S1) of the stopper projection (131) may correspond to the inclined portion (C) of the oxygen container (2) and support the inclined portion (C). As a result, the oxygen container (2) may be supported by being pressed in the protruding direction of the stopper projection (131).

The intermediate inclined portion (1313) is arranged between the contact portion (1311) and the contact release portion (1312), and is inclined from the contact portion (1311) toward the contact release portion (1312). The extension portion (142) includes an extension projection (1421) and a corresponding inclined portion (1422). The extension projection (1412) may be arranged at an end of the extension bar (142). The corresponding slope (1422) is arranged on the side of the extension protrusion (1412) and corresponds to the intermediate slope (1313). By the upward movement of the lever (141), the corresponding slope (1422) comes into contact with the intermediate slope (1313), and the stopper protrusion (131) is gradually pressed. By the further upward movement of the lever (141), the extension protrusion (1421) comes into contact with the contact portion (1311). By this, the stopper protrusion (131) is fully pressed and can sufficiently protrude outward from the support shaft (110).
