Description

Technical Field

[0001] The invention relates to the technical field of medical infusion devices, in particular to a disposable self-heating and self-inflating heating and pressurizing infusion device. Background Art

[0002] At present, the commonly used pressurized infusion device in clinical practice is to manually pressurize the airbag and indirectly apply pressure to the infusion bag through the pressurized airbag to achieve pressurized rapid infusion. However, the installation and pressurization operation of the pressurized infusion device is relatively complicated and cumbersome. It takes a certain amount of time from installation and fixation to completion of pressurization. Therefore, it is time-consuming and labor-intensive to rescue patients, especially emergency fluid resuscitation, and delays the treatment opportunity. The existing heated infusion devices are roughly divided into two categories: one is to add a section of infusion pipeline with a heating plate to the existing infusion pipeline, and the liquid is directly heated when passing through the heating plate; the other is to pass the existing infusion pipeline through a heated water tank to indirectly heat the liquid in the pipeline. Both of these heating methods require the additional installation of corresponding infusion pipelines and auxiliary external heating equipment. The installation steps are complicated and the operation is cumbersome. And there is currently no infusion device that has both heating and pressurization functions.

[0003] If the height difference between the infusion bag and the patient is limited, the normal infusion speed will be limited, or it will not be possible to increase the infusion speed by adjusting the height of the infusion bag. Therefore, when patients need rapid fluid resuscitation, how to achieve pressurized infusion efficiently and accurately in the shortest time is crucial to saving lives. In addition, once a crew member falls into the water, they are usually accompanied by hypothermia and hypothermia. Therefore, for the rescue of the wounded who fall into the water, rapid temperature resuscitation and correction of hypothermia play a key role in correcting the "death triad" and reversing the disease outcome. The infusion auxiliary equipment designed with both heating and pressurized infusion functions and simple and convenient operation can meet the actual needs of medical care and improve the efficiency of patient treatment. Summary of the invention

[0004] The purpose of the present invention is to provide a disposable self-heating and self-inflating heating and pressurizing infusion device, which can quickly and conveniently provide heating and pressurizing effects for infusion, is simple and convenient to operate, has the functions of heating and pressurizing infusion, is not restricted by the infusion height, and can be used for rapid infusion and body temperature resuscitation treatment of patients.

[0005] The technical solution of the present invention is: a disposable self-heating and self-inflating heating and pressurizing infusion device, comprising a shell, an air bag, a self-heating patch, a calcium peroxide bag and a water bag;

[0006] The shell is a transparent, heat-insulating, soft polyester fiber shell; the bottom of the shell is provided with a self-collecting bottle mouth that can adapt to and fix the openings of infusion bags of different calibers; the self-collecting bottle mouth is made of elastic rubber material.

[0007] An airbag is arranged in the shell, the outer wall of the airbag is in close contact with the inner wall of the shell, the inner wall of the airbag is made of soft heat-resistant polyester fiber, the infusion bag is wrapped in the middle part of the airbag and is in direct contact with the inner wall of the airbag, and when the airbag is inflated and enlarged, it can pressurize the infusion bag for infusion;

[0008] The self-heating patch is arranged inside the airbag and is attached to the inner surface of the outer wall of the airbag for one circumference. The self-heating patch is filled with reducing iron powder, which can undergo oxidation reaction with oxygen to release heat, and heat the infusion bag placed in the middle of the airbag through heat conduction.

[0009] The calcium peroxide bag and the water bag are arranged inside the air bag, the lower surface of the calcium peroxide bag is connected to the water bag via a thin and tough film, and fine pores are left on the upper part of the calcium peroxide bag. When the thin and tough film is squeezed through the extrusion action to press the water in the water bag into the calcium peroxide bag, the calcium peroxide in the calcium peroxide bag will chemically react with the water to generate oxygen and calcium hydroxide, and the oxygen will be released into the air bag through the fine pores on the upper part of the calcium peroxide bag, thereby increasing the air pressure in the air bag and causing the self-heating patch to generate heat.

[0010] Furthermore, it also includes a fixed hook, the upper part of which is used to fix the entire device on the top of the cabin or on an infusion stand, and the lower part of the fixed hook passes through the shell and the airbag and is used to fix the infusion bag placed therein.

[0011] Furthermore, the calcium peroxide bag and the water bag are fixedly adhered to the inside of the airbag.

[0012] The beneficial effects of the present invention are as follows: the present invention improves the efficiency and flexibility of the application of the heating and pressurized infusion device in medical work by designing a rapid heating and pressurized infusion device; by introducing the design of the heating chamber and the pressurized chamber, the functions of rapid infusion and heating and infusion are simultaneously realized. Specifically, the present invention generates oxygen through the chemical reaction of calcium peroxide and water, automatically inflates and pressurizes the airbag, and then pressurizes the infusion bag to achieve pressurized rapid infusion; at the same time, the oxygen released by the reaction of calcium peroxide and water can chemically react with the reduced iron powder in the self-heating patch, continuously releasing a large amount of heat, and then heats the infusion bag through heat conduction to achieve liquid heating. Therefore, the present device can achieve heating and pressurized infusion at the same time. The entire operation only requires placing the infusion bag into and fixing it inside the airbag, fixing the lower bag opening in the self-collecting bottle opening, and squeezing the water bag to press the water into the calcium peroxide bag. All installation steps are simple and quick, avoiding the tedious and time-consuming manual squeezing of the airbag in traditional pressurized infusion devices, shortening the preparation time for rescue and fluid resuscitation, and meeting the actual requirements of large-scale rapid infusion and body temperature resuscitation.

[0016] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0017] As attached Figure 1 As shown, this embodiment is a disposable self-heating and self-inflating heating and pressurizing infusion device, including: a fixed hook 1, which hangs and fixes the entire device including the infusion bag inside to the infusion stand; a high temperature resistant polyester fiber shell 2, which can withstand a certain temperature and does not produce toxic and harmful substances. The upper part of the shell is connected to the fixed hook 1, and the lower part is connected to the self-collecting bottle mouth 8. The shell contains an air bag 5, a calcium peroxide bag 6 and a water bag 7. The outer wall of the air bag 5 is in close contact with the heat-resistant polyester fiber shell 2, and the inner wall is a soft heat-resistant polyester fiber. Preheating will not produce toxic and harmful substances. The inner wall is in direct contact with the infusion bag, and the heat generated by the self-heating patch is directly conducted to the infusion bag suspended therein. The calcium peroxide bag 6 is fixed to the inner surface of the outer wall of the airbag, and the lower end is connected to the water bag through a thin and tough film. There are fine pores on the upper part, and the oxygen generated by the chemical reaction between the calcium peroxide bag and the water can be released into the airbag, increasing the pressure in the airbag, playing the role of pressurized infusion. At the same time, the oxygen entering the airbag will react with the reduced iron powder in the self-heating patch 3 to generate iron oxide and release a large amount of heat. The heat is conducted to the liquid in the infusion bag through the inner wall of the airbag, playing the role of heating infusion. The water bag 7 is located at the bottom of the device, the inner surface of the outer wall of the airbag, and is close to the bottom of the calcium peroxide bag. It stores 15ml of pure water, and is separated from the calcium peroxide bag by a thin plastic film. Before use, the water in the water bag is pressed into the calcium peroxide bag by extrusion, so that the calcium peroxide and water react chemically to generate oxygen and calcium hydroxide. The oxygen is released into the airbag through the fine pores on the upper end of the calcium peroxide bag, increasing the air pressure in the airbag and causing the self-heating patch to generate heat, playing the role of heating and adding liquid infusion.

[0018] As attached Figure 2 As shown, before use, the infusion bag is fixed in the device through the hook 1 on the upper part of the shell and the sealing ring on the lower part. After the infusion bag is installed and fixed, the water bag is pressed to squeeze the water into the calcium peroxide bag, and the device can start self-heating and self-inflation, and quickly and conveniently complete the heated and pressurized infusion. The problem of limited infusion speed control and the demand for pressurized infusion are solved.

[0019] Through the above improvements, the present invention solves 1. the practical difficulty that the infusion speed is limited by the infusion height; 2. the practical problem that the incidence of hypothermia in traumatic patients in World War II is high and temperature resuscitation is urgent. The invention is simple, convenient and fast to operate, and an integrated device with the functions of heating and pressurized infusion is designed. Self-heating and self-inflating heated and fluid-added infusion can be completed through a few simple steps. It can be used for rapid volume resuscitation and temperature resuscitation treatment of critically ill patients in various rescue environments, as well as heating and pressurized treatment of conventional infusion.

[0020] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
