Description

Technical Field

[0001] The utility model relates to the field of medical supplies, in particular to a back-type oxygen bag pressurizing and fixing device. Background Technique

[0002] Oxygen bags are widely used in medical sites, mainly in hospital operating rooms, emergency rooms, ICUs, wards and other occasions. It is especially suitable for providing oxygen to critically ill patients with spontaneous breathing, such as those with heart failure, myocardial infarction, asthma, pneumothorax, hypoxia, etc., during short-distance transfer and escort or rescue. The main features of oxygen bags are light weight, easy to carry and store, which makes it possible to be widely used in pre-hospital first aid, patient transfer and primary medical institutions. However, there are some problems with traditional oxygen bags during use. For example, after a certain amount of oxygen is output from the oxygen bag, the internal pressure will gradually decrease, and it is necessary to apply a certain pressure manually to maintain the oxygen flow output. This method is not only time-consuming and laborious, but also difficult to ensure the uniform output of oxygen flow, and sometimes even leads to the interruption of oxygen supply. Especially in emergency situations, this manual pressurization method may increase the workload of medical staff and affect the rescue efficiency.

[0003] In clinical nursing practice, existing oxygen bags often have a pillow shape and only two openings for hanging ropes. Whether for carrying or fixing, they are not firm. Medical staff need to continuously hold the position of the oxygen bag by hand during use. And the oxygen flow rate in the bag is unstable. As the oxygen in the bag gradually decreases, the flow rate changes from fast to slow, unable to meet the oxygen supply needs of patients. To solve this problem, a patent with the application number 201821807786.8 currently discloses a medical oxygen bag automatic pressurization device, which realizes that the placement plate automatically squeezes the oxygen bag according to the volume reduction of the oxygen bag through the action of the first elastic member and the restoring force, so as to achieve the normal output of the oxygen supply pressure. However, this patent is not convenient to carry and transport, and needs to select an appropriate position to place and use during use, and cannot be fixedly placed. The placement box of the oxygen bag cannot be adjusted in size and is not suitable for oxygen bags of different sizes. Content of the Utility Model

[0004] In order to overcome the above deficiencies of the prior art, the utility model provides a back-type oxygen bag pressurizing and fixing device that can stably place the oxygen bag, is convenient to carry, facilitates pressure adjustment, and can adapt to oxygen bags of different sizes.

[0005] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0006] A back-type oxygen bag pressurizing and fixing device includes a back plate, two shoulder straps fixedly connected to the back plate, a pressurizing plate cooperating with the back plate, and an adjusting assembly connected between the back plate and the pressurizing plate;

[0007] The shoulder straps are spaced apart, and a space capable of accommodating an oxygen bag is formed between the backrest plate and the pressure plate. An adjusting assembly is provided on each of the left and right sides of the backrest plate and the pressure plate. The adjusting assembly includes an adjusting rope connected to the side of the backrest plate, a fixing strap connected to the side of the pressure plate, and a mother-and-son buckle connected between the adjusting rope and the fixing strap;

[0008] The backrest plate and the pressure plate can clamp the front and back sides of the oxygen bag to ensure that the oxygen bag is stable and not prone to sliding during carrying and use. The adjusting assembly can adjust the distance between the backrest plate and the pressure plate, and the user can adjust the pressure according to the inflation degree of the oxygen bag. For example, during use, the gas in the oxygen bag will decrease, and at this time, the oxygen output flow rate will also slow down. At this time, the user can pull the adjusting assembly to shorten the distance between the backrest plate and the pressure plate, squeeze the oxygen bag to increase the gas pressure, thereby accelerating the oxygen output flow rate. The adjusting assembly can also be composed of an elastic adjusting belt and a buckle;

[0009] The bottom and the lower part of the side of the backrest plate and the pressure plate are connected by an elastic net pocket, which facilitates placing the oxygen bag between the backrest plate and the pressure plate and prevents the oxygen bag from falling from between the backrest plate and the pressure plate.

[0010] As a further technical improvement, the middle section of the adjusting rope is fixedly connected to the son buckle in a mother-and-son buckle. Two adjusting rope loops are provided on each side of the backrest plate. The two ends of the adjusting rope respectively pass through an adjusting rope loop, and finally are adjustably connected by a spring buckle together; when it is necessary to increase the distance between the backrest plate and the pressure plate, press the button on the spring buckle. At this time, the adjusting rope can freely pass through the spring buckle, move the spring buckle towards the two ends of the adjusting rope and release it to fix; when it is necessary to reduce the distance between the backrest plate and the pressure plate, move the spring buckle towards the middle section of the adjusting rope and fix it.

[0011] As a further technical improvement, one end of the fixing strap is fixedly installed on the side of the pressure plate, and the other end of the fixing strap is fixedly connected to the mother buckle in a mother-and-son buckle; the mother buckle can be used in cooperation with the son buckle to fixedly connect the adjusting rope and the fixing strap.

[0012] As a further technical improvement, a shoulder strap adjusting buckle is provided on the shoulder strap to facilitate adjusting the tightness of the two shoulder straps.

[0013] As a further technical improvement, the materials of the backrest plate and the pressure plate are PVC plates or wood, which are light and durable.

[0014] As a further technical improvement, the materials of the adjusting rope and the fixing strap are nylon; they have good elasticity and durability and can adapt to frequent stretching and recovery.

[0015] The working principle of the present utility model:

[0016] In use, medical staff can place the oxygen bag between the backrest plate and the pressure plate. The oxygen bag is supported by an elastic mesh bag, and then the mother and son lock buckles are fixed in cooperation. Through the spring buckle in the adjustment component, preliminary adjustment is carried out so that the pressure received by the oxygen bag can stably output oxygen. The device is carried on the back through the shoulder strap for medical operations. When the volume of the gas in the oxygen bag decreases, the two ends of the adjustment rope are pulled out through the spring buckle, so that the oxygen bag is squeezed by the backrest plate and the pressure plate to an appropriate degree to achieve the required oxygen output flow rate.

[0017] Compared with the prior art, the advantages and beneficial effects of the present utility model are as follows:

[0018] 1. The present utility model enables medical staff to carry the oxygen bag on their backs for work or carrying, so as to perform other medical operations.

[0019] 2. The distance between the backrest plate and the pressure plate of the present utility model is easy to adjust, and the pressure received by the oxygen bag can be manually adjusted to maintain stable output.

[0020] 3. The spring buckle in the present utility model can lock the degree of the adjustment rope after adjusting the distance between the backrest plate and the pressure plate.

[0021] 4. The present utility model is applicable to oxygen bags of different sizes and has wide applicability. BRIEF DESCRIPTION OF THE DRAWINGS
