Description

Technical Field

[0001] The utility model belongs to the technical field of oxygen bags, and particularly relates to an oxygen bag pressurizing device. Background Art

[0002] Medical oxygen bags are commonly used oxygen containers in clinics and are often used in patient transfer or first aid. Since the oxygen inside the medical oxygen bag is stored in a gaseous state, during use, as the amount of oxygen decreases, its output pressure gradually weakens and cannot meet the oxygen supply demand. At this time, external force must be applied by manually pressing the medical oxygen bag to ensure the normal output of the oxygen supply pressure of the medical oxygen bag.

[0003] In the prior art, there is a medical oxygen bag pressurizing supply device with a patent publication number of CN219614639U. The above patent includes a medical oxygen bag and an oxygen supply catheter. The first end of the oxygen supply catheter is connected and communicated with the oxygen supply port of the medical oxygen bag; the medical oxygen bag pressurizing supply device further includes an air pressurizing bag and an inflation device; the medical oxygen bag is located inside the air pressurizing bag, and the second end of the oxygen supply catheter extends outside the air pressurizing bag; an inflation port is provided on the air pressurizing bag, and the inflation device is communicated with the inflation port through an inflation catheter. This medical oxygen bag pressurizing supply device can continuously apply pressure to the medical oxygen bag to ensure the normal output of the oxygen supply pressure of the medical oxygen bag, with simple operation and good oxygen supply effect. However, there are still the following deficiencies in actual use: In practice, when pressurizing the oxygen in the oxygen bag, a large amount of air needs to be filled into the air pressurizing bag to squeeze the oxygen bag and extrude the oxygen. Since the material of the oxygen bag itself is relatively thick, a large air pressure is required to achieve the pressurizing work on it, which has high requirements for the air pressurizing bag and increases the production cost. At the same time, when the oxygen bag releases oxygen, the oxygen delivery can only be achieved through the action of external pressure, and the self-pressurized delivery work cannot be realized, thus increasing the operation cost of medical staff.

[0004] Therefore, an oxygen bag pressurizing device is needed to solve the problems of inconvenient pressurization process of the oxygen bag and inability to achieve self-pressurized oxygen delivery in the prior art. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an oxygen bag pressurizing device to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solution: An oxygen bag pressurizing device includes an oxygen bag, an inflation catheter, and an oxygen delivery tube. The inflation catheter is connected to the right side of the oxygen bag, the oxygen delivery tube is connected to the left side of the oxygen bag, a pressure gauge is connected to the oxygen delivery tube, a pressurizing mechanism is arranged on the front side of the oxygen bag, and an elastic band is connected inside the oxygen bag.

[0007] The pressurizing mechanism includes a connecting pipe which penetrates into the oxygen bag. An inflation ball is connected to the inner end of the connecting pipe, and a one-way valve is fixedly connected to the outer end of the connecting pipe. The other end of the one-way valve is connected to a pressurizing airbag through a pipeline. The design of the one-way valve ensures that oxygen will not flow back between the manual pump and the oxygen bag. The pressurizing airbag is similar to the manual airbag pump of a sphygmomanometer, and the user can increase the pressure inside the oxygen bag by squeezing the pressurizing airbag.

[0008] It should be noted in the solution that a storage oxygen cavity is formed between the oxygen bag and the inflation ball for storing oxygen.

[0009] Furthermore, it is worth noting that the oxygen bag is made of thermoplastic polyurethane or nylon composite material to ensure that the oxygen bag is light and pressure-resistant.

[0010] Furthermore, it should be noted that an air pump is connected to the connecting pipe through a one-way valve.

[0011] As a preferred embodiment, two elastic bands are provided. The two elastic bands are arranged to match the inner wall of the oxygen bag and are provided on the left and right sides.

[0012] As a preferred embodiment, the elastic band is made of rubber material.

[0013] As a preferred embodiment, the inflation ball is made of elastic material.

[0014] Compared with the prior art, the oxygen bag pressurizing device provided by the present utility model has at least the following beneficial effects:

[0015] (1) During the pressurization of the oxygen bag by the provided pressurizing mechanism, the pressurization work is carried out from the inside to the outside, which is a process of pressurizing the oxygen in the storage oxygen cavity. The air pressure required is relatively low, which facilitates the pressurization work inside the oxygen bag, improves the practicability of the device, and at the same time, the setting of the pressure gauge is convenient for controlling and observing the pressure during the oxygen delivery process.

[0016] (2) By arranging the elastic band inside the oxygen bag, when the oxygen bag is filled with oxygen, the elastic band will be pulled and stretched. Thus, during the oxygen delivery process, as the amount of oxygen in the oxygen bag decreases, the pulling force on the elastic band gradually decreases. Through the elastic action of the elastic band, the self-pressurization work of the oxygen bag is realized, so as to facilitate the stable oxygen delivery work. Description of the Drawings

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0023] Please refer to Figures 1-3 , the present invention provides an oxygen bag pressurizing device, including an oxygen bag 1, an inflation conduit 2 and an oxygen delivery tube 3. The inflation conduit 2 is connected to the right side of the oxygen bag 1, the oxygen delivery tube 3 is connected to the left side of the oxygen bag 1, a pressure gauge 301 is connected to the oxygen delivery tube 3, a pressurizing mechanism 4 is arranged on the front side of the oxygen bag 1, and an elastic band 5 is connected inside the oxygen bag 1.

[0024] The pressurizing mechanism 4 includes a connecting tube 401. The connecting tube 401 penetrates into the oxygen bag 1. One end inside the connecting tube 401 is connected to an inflating balloon 404. The outer end of the connecting tube 401 is fixedly connected to a check valve 402. The other end of the check valve 402 is connected to a pressurizing airbag 403 through a pipeline. An air pump is connected to the connecting tube 401 through the check valve 402. The inflating balloon 404 is made of an elastic material. The design of the check valve 402 ensures that oxygen will not flow back between the manual pump and the oxygen bag 1. The pressurizing airbag 403 is similar to the manual airbag pump of a sphygmomanometer. Users can increase the pressure inside the oxygen bag 1 by squeezing the pressurizing airbag 403.

[0025] Further, as Figure 2 and Figure 3 shown, it is worth specifically stating that an oxygen storage cavity 101 is formed between the oxygen bag 1 and the inflatable balloon 404 for storing oxygen.

[0026] During use, it is connected to the pressurized airbag 403 or an air pump through the one-way valve 402 to pump gas into the inflatable balloon 404 to make it expand. The gas enters the inflatable balloon 404 through the one-way valve 402 by means of the pressurized airbag 403 or the air pump. With the setting of the one-way valve 402, air backflow can be avoided, and thus it is easy to inflate and expand the inflatable balloon 404. Due to the expansion of the inflatable balloon 404, the oxygen in the oxygen storage cavity 101 inside the oxygen bag 1 will be squeezed, enabling the oxygen to be transported through the oxygen delivery tube 3. And through the pressure gauge 301, it is convenient to adjust and observe the delivery pressure and the oxygen pressure inside the oxygen bag 1 to improve the stability of the delivery process.

[0027] According to the above working process, it can be seen that during the pressurization process of the oxygen bag 1 by the provided pressurization mechanism 4, the pressurization work is carried out from the inside to the outside, which is a process of pressurizing the oxygen in the oxygen storage cavity 101. The required air pressure is relatively low, thus facilitating the pressurization work on the oxygen bag 1, improving the practicability of the device. At the same time, in cooperation with the setting of the pressure gauge 301, it is convenient to control and observe the pressure during the oxygen delivery process.

[0028] Further, as Figures 1-3 shown, it is worth specifically stating that the oxygen bag 1 is made of thermoplastic polyurethane or nylon composite material to ensure that the oxygen bag 1 is light and pressure-resistant.

[0029] Further, as Figure 2 and Figure 3 shown, it is worth specifically stating that there are two elastic bands 5. The two elastic bands 5 are arranged on the left and right sides in a matching manner along the inner wall of the oxygen bag 1, and the elastic bands 5 are made of rubber material.

[0030] During use, while oxygen is injected into the oxygen bag 1, the oxygen bag 1 will expand and pull the elastic bands 5 to cause elastic deformation. When oxygen is delivered through the oxygen delivery tube 3, in the case where the oxygen in the oxygen storage cavity 101 gradually decreases, through the elastic recovery effect of the elastic bands 5, the oxygen bag 1 squeezes the oxygen storage cavity 101, thus facilitating the stable self-delivery of the oxygen in the oxygen storage cavity 101. Then, in cooperation with the operation of the pressurization mechanism 4, the oxygen delivery efficiency can be improved.

[0031] This solution has the following working process: When this device is in use, it is connected to the pressurized airbag 403 or an air pump through the one-way valve 402, which is used to pump gas into the inflatable balloon 404 to make it expand. The gas enters the inflatable balloon 404 through the one-way valve 402 by means of the pressurized airbag 403 or the air pump. With the setting of the one-way valve 402, air backflow can be avoided, and thus it is easy to inflate and expand the inflatable balloon 404. When the inflatable balloon 404 expands, it will squeeze the oxygen in the oxygen storage chamber 101 of the oxygen bag 1, enabling the oxygen to be transported through the oxygen delivery tube 3. And through the pressure gauge 301, it is convenient to adjust and observe the delivery pressure and the oxygen pressure in the oxygen bag 1. At the same time, through the inflation conduit 2, it is convenient to inject oxygen into the oxygen bag 1 for reuse. When injecting oxygen into the oxygen bag 1, the oxygen bag 1 will expand and pull the elastic band 5 to cause elastic deformation. When delivering oxygen through the oxygen delivery tube 3, in the case where the oxygen in the oxygen storage chamber 101 gradually decreases, through the elastic recovery of the elastic band 5, the oxygen bag 1 squeezes the oxygen storage chamber 101, thus facilitating the stable and autonomous delivery of oxygen in the oxygen storage chamber 101. Furthermore, by cooperating with the operation of the pressurizing mechanism 4, the oxygen delivery efficiency can be improved.

[0032] In summary: Through the set pressurizing mechanism 4, during the pressurization process of the oxygen bag 1, the pressurization work is carried out from the inside to the outside, which is a process of pressurizing the oxygen in the oxygen storage chamber 101. The required air pressure is relatively low, thus facilitating the pressurization work on the oxygen bag 1 and improving the practicality of the device. At the same time, in cooperation with the setting of the pressure gauge 301, it is convenient to control and observe the pressure during the oxygen delivery process; through the elastic band 5 arranged inside the oxygen bag 1, when the oxygen bag 1 is filled with oxygen, it will pull the elastic band 5 to make it stretch. Therefore, during the oxygen delivery process, as the oxygen amount in the oxygen bag 1 decreases, the pulling force on the elastic band 5 gradually decreases. Through the elastic effect of the elastic band 5, the self-pressurization work of the oxygen bag 1 is realized, so as to facilitate the stable delivery of oxygen.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
