Description

Technical Field

[0001] This utility model relates to the field of infectious disease nursing equipment technology, specifically to a respirator for infectious disease nursing. Background Technology

[0002] Infectious disease ventilators are medical devices specifically designed for infectious disease nursing scenarios. They are mainly used to assist or replace patients' breathing functions, especially when patients' lungs are severely impaired due to infection or disease, in order to reduce the risk of viral or bacterial transmission. When ventilators are used in conjunction with the nursing care of patients in the infectious disease department, traditional ventilators do not have a filtration and disinfection function. As a result, bacteria and viruses generated by the patient's breathing are dispersed in the air, which can lead to bacterial infections among medical staff when they use the ventilators in conjunction with nursing care.

[0003] To overcome the above-mentioned defects, in the prior art 1 (Chinese patent application number CN201922100946.6, application date 2019-11-29), a respirator for infectious disease nursing care, most of the virus-containing air enters the filter element through the exhaust port, is filtered, and then exits the filter from the outlet. To improve the filtration effect of the filter, the outlet can be connected to a negative pressure generating device. A small portion of the virus-containing gas entering the trachea through the wedge-shaped channel is flushed back into the airway by oxygen during the next compression of the airbag, which can filter most viruses and bacteria and reduce the probability of infection for medical staff. Although the prior art can filter and disinfect the air exhaled by patients, improving the safety of medical staff, when patients cooperate with the respirator for assisted breathing, the air delivery tube may loosen and fall off due to the dragging of patients or medical staff, reducing the stability of the air delivery tube and making it less practical. Therefore, the respirator for infectious disease nursing care was proposed to solve the above problems. Summary of the Invention

[0004] The purpose of this utility model is to provide a ventilator for infectious disease nursing, in order to solve the problem mentioned in the background art that when patients use ventilators for assisted breathing, the air delivery tube may become loose and fall off due to dragging by the patient or medical staff, which reduces the stability of the air delivery tube and makes it less practical.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a respirator for infectious disease nursing, comprising a compression airbag and an air inlet pipe disposed at the top of the compression airbag for air intake, and an air delivery pipe disposed at the bottom of the compression airbag for air exhaust, wherein the bottom end of the air delivery pipe is connected to a mounting plate via an adjusting valve, mounting plates are symmetrically mounted on the left side of the compression airbag, and clamps are mounted on the opposite sides of the two mounting plates, and air delivery pipes are correspondingly disposed on the inner sides of the two clamps, wherein a connecting plate is mounted at the top end of the air delivery pipe, and the connecting plate is disposed on the inner bottom of the compression airbag, wherein limit blocks are slidably mounted at both ends of the inner side of the connecting plate, and the two limit blocks extend through into the interior of the compression airbag.

[0006] Preferably, the limiting block is arc-shaped, and the two limiting blocks are symmetrically arranged about the vertical center line of the connecting plate.

[0007] Preferably, one end of a compression spring is symmetrically connected inside the connecting disc, and the two compression springs have the same structure, and the other end of the two compression springs is connected to a limit block.

[0008] Preferably, the bottom of the compression airbag is symmetrically fitted with pressing rods through a return spring, and the inner ends of the two pressing rods correspond to limit blocks.

[0009] Preferably, the inner sides of the two clamps are provided with anti-slip pads, and the two anti-slip pads are made of rubber material, and the inner sides of the two anti-slip pads are attached to the outer side wall of the air supply pipe.

[0010] Preferably, the two clamps are semi-circular in shape.

[0011] Preferably, a pull rod is provided on the front side of the clamping plate, and the pull rod extends through a tension spring to the outer front end of the mounting plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] (1) Setting limit blocks, using the connecting plate set at the top of the air supply pipe, when it is necessary to position and connect the air supply pipe and the compression air bag, simply insert the connecting plate set at the top of the air supply pipe into the bottom inner side of the compression air bag. At this time, the two limit blocks with inclined arc shape retract and move. Then, the two compression springs will also automatically pop the two limit blocks into the interior of the compression air bag through their own elasticity. This can achieve the positioning and fixing of the air supply pipe after connection, avoiding the phenomenon of loosening and falling off due to dragging during later use, and improving stability.

[0014] (2) Furthermore, when it is necessary to disassemble and replace the air supply pipe, simply press the two pressing rods to retract and move them, so that the two arc-shaped pressing rods squeeze the two limiting blocks and retract and move them into the interior of the connecting plate, thereby making it easy to pull the air supply pipe out from the bottom of the squeezing air bag for replacement, making the operation more time-saving and labor-saving.

[0015] (3) Furthermore, by using the reset springs provided on the outside of the two pressing rods, the position of the two pressing rods after they have been pressed and moved can be elastically reset by the elastic force of the two reset springs themselves, so as to facilitate repeated pressing and installation in the later stage, which is more practical.

[0016] (4) A clamp is provided. A mounting plate is symmetrically set on the left side of the compression airbag, and a clamp is installed on the opposite side of the two mounting plates. At the same time, an air supply tube is attached to the inner side of the two clamps through an anti-slip pad. The two clamps can be used to position and clamp the air supply tube after placement through the anti-slip pad, so as to avoid the phenomenon of the mask loosening and falling off when wearing it, and to avoid the phenomenon of bacteria growing when the mask falls to the ground.

[0017] (5) Furthermore, when it is necessary to use a mask to assist the patient's breathing, simply pull the lever to move the front clamp through the tension spring, so that the air tube is separated from the clamp. At this time, the air tube can be easily removed from the two clamps for later use in assisting the patient's breathing, which is more practical. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides the following technical solution: a respirator for infectious disease nursing:

[0027] Example 1: To address the issue that in existing ventilator-assisted breathing, the air delivery tube 3 may loosen and fall off due to dragging by the patient or medical staff, reducing its stability and practicality, the following invention is disclosed: a compression airbag 1, and an air inlet tube 2 located at the top of the compression airbag 1 for air intake, and an air delivery tube 3 located at the bottom of the compression airbag 1 for air exhaust. The bottom end of the air delivery tube 3 is connected to a mounting plate 6 via an adjusting valve 5. Mounting plates 6 are symmetrically mounted on the left side of the compression airbag 1, and clamping plates 9 are mounted on opposite sides of the two mounting plates 6. The air delivery tube 3 is located on the inner side of the two clamping plates 9. A connecting plate 12 is mounted at the top of the air delivery tube 3, and the connecting plate 12 is located on the inner bottom of the compression airbag 1. Limiting blocks 13 are slidably mounted at both ends inside the connecting plate 12, and the two limiting blocks 13 extend through the interior of the compression airbag 1.

[0028] The two limiting blocks 13 are arc-shaped and are symmetrically arranged about the vertical center line of the connecting plate 12. One end of the compression spring 14 is symmetrically connected inside the connecting plate 12, and the two compression springs 14 have the same structure. The other end of the two compression springs 14 is connected to the limiting block 13. The bottom of the compression airbag 1 is symmetrically installed with a pressing rod 7 through a reset spring 15, and the inner ends of the two pressing rods 7 correspond to the limiting blocks 13.

[0029] like Figures 1-6As shown, when a ventilator is needed to assist breathing for patients in the infectious disease department, simply insert the connecting plate 12 at the top of the air delivery tube 3 into the bottom inner side of the compression bag 1. At this time, the two arc-shaped limiting blocks 13 will contract and move under the compression of the compression bag 1, causing the two limiting blocks 13 to contract and move into the interior of the connecting plate 12. Then, the two compression springs 14 will automatically pop the two limiting blocks 13 into the interior of the compression bag 1 through their own elasticity. This can limit and fix the position of the connected air delivery tube 3, preventing the air delivery tube 3 from loosening and falling off due to dragging during later use, thus improving stability. When it is necessary to disassemble and replace the air delivery tube 3, simply press the two pressing rods 7 to contract and move them. The two pressing rods 7 will compress the two limiting blocks 13 and move them into the interior of the connecting plate 12, thus separating the air delivery tube 3 from the compression bag 1. This allows for quick disassembly and replacement of the air delivery tube 3, making the operation more time-saving and labor-saving.

[0030] Example 2 differs from Example 1 in that it allows for clamping and positioning of the face mask 4, preventing it from falling to the ground and causing bacterial growth, thus improving hygiene. The following is disclosed:

[0031] The inner sides of the two clamping plates 9 are provided with anti-slip pads 10, and the two anti-slip pads 10 are made of rubber material. The inner sides of the two anti-slip pads 10 are attached to the outer side of the air supply pipe 3. The two clamping plates 9 are semi-circular in shape. The front side of the clamping plates 9 is provided with a pull rod 8, and the pull rod 8 extends through the tension spring 11 to the outer front end of the mounting plate 6.

[0032] like Figures 1-5 As shown, when using the mask 4 to assist patients in respiratory care in the infectious disease department, simply pull the lever 8 to drive the clamp 9 and the air tube 3 apart through the tension spring 11. At this time, the air tube 3 can be removed from the two air tubes 3 for later use of the mask 4 to assist patients in respiratory care. After the nursing treatment is completed, simply place the air tube 3 back on the inside of the two clamps 9. At this time, the tension spring 11 will elastically reset the position of the lever 8 after pulling through its own elasticity, so that the two clamps 9 can clamp and position the air tube 3 after placement through the anti-slip pad 10, preventing the mask 4 from loosening and falling off after use, thus preventing the mask 4 from falling to the ground and causing bacterial growth, and improving hygiene.
