Description

Technical Field

[0001] The utility model relates to a medical device, in particular to a heating and pressurizing belt for rapid infusion or blood transfusion. Background Art

[0002] In operating rooms, emergency departments and other clinical departments, patients often need a large amount of rapid intravenous infusion in a short period of time to save their lives due to hemorrhagic shock, infectious toxic shock, anaphylactic shock and other reasons. In this case, an infusion pressure bag is often used to pressurize the infusion bag to help the blood, crystalloid, colloid and other bagged liquids be infused into the body as quickly as possible.

[0003] The infusion pressurized bag in the prior art generally includes an air storage bag, an inflatable ball connected to the air storage bag through an air injection tube, and an air valve arranged on the air injection tube. When in use, the infusion bag is placed in the interlayer of the air storage bag, and the inflatable ball is pinched by hand to inflate, and a certain pressure is maintained according to the infusion speed. After the infusion is completed, the air valve is opened to discharge the gas in the air storage bag. Although the purpose of rapid infusion can be achieved with the help of an infusion pressurized bag, it still has certain defects in clinical use, mainly manifested as: the existing infusion pressurized bag does not have a heating function. When used in cold seasons, especially in the treatment of field combat trauma, the infused liquid cannot be preheated. If the liquid is directly and quickly infused into the patient's body, the patient may suffer from hypothermia and chills due to the low temperature of the infused liquid. In severe cases, the patient may suffer from abnormal coagulation, abnormal blood pressure, arrhythmia, or even cardiac arrest, which endangers the patient's life safety.

[0004] For the above reasons, when conditions permit, medical staff will first use warm water to preheat the infused liquid, and then quickly infuse the liquid into the patient's body with the help of an infusion pressure bag. However, this method requires medical staff to do more preliminary preparation work, which increases the workload. In addition, if the preheated liquid is not infused in time, its temperature will easily drop without insulation measures, and the expected treatment effect cannot be achieved. Utility Model Content

[0005] In order to solve the above deficiencies in the prior art, the utility model aims to provide a heating and pressurizing belt for rapid infusion or blood transfusion, so as to achieve the purpose of rapidly and safely infusing liquid into a patient's body.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is as follows: a heating and pressurizing belt for rapid infusion or blood transfusion, comprising a long strip with Velcro at both ends to form a ring; the long strip is a sandwich structure, an air storage bag is arranged in the cavity, and a water storage ring tube is attached to the inner side of the long strip;

[0007] It also includes an inflatable ball connected to the air storage bag through an air injection pipe, and a water injection pipe connected to the water storage annular pipe; wherein an air valve is provided on the air injection pipe, and a sealing cover is detachably provided at the water injection port of the water injection pipe.

[0008] As a limitation of the present utility model, a gauze bag for positioning the infusion bag is attached to the inner side of the water storage annular tube.

[0009] As a further limitation of the utility model, a temperature sensor is provided in the water storage annular tube, and a digital display screen is fixedly provided on the outer side of the long strip;

[0010] The temperature sensor is electrically connected to the digital display screen.

[0011] As another limitation of the present invention, the water storage annular pipe is composed of S-shaped distributed pipelines.

[0012] As a further limitation of the present utility model, the water injection port of the water injection pipe is a tapered port.

[0013] As a further limitation of the present invention, a sling is fixedly provided on the long belt.

[0014] Due to the adoption of the above technical solution, the utility model has the following beneficial effects compared with the prior art:

[0015] (1) The utility model is an improvement on the structure of an infusion pressurized bag. The specific improvement lies in that a water storage ring tube is attached to the inner side of a long strip provided with an air storage bag. After warm water is injected, the utility model can simultaneously have the functions of heating and pressurizing. Thus, the liquid can be preheated and then rapidly injected into the patient's body by using the pressurizing function. In cold seasons, especially in the treatment of trauma in the field, it can ensure that the liquid rapidly injected into the patient's body is close to body temperature, thus avoiding hypothermia, chills, abnormal coagulation, abnormal blood pressure or arrhythmia caused by the low temperature of the injected liquid, and can effectively improve the safety of the patient when rapidly injecting liquid or blood.

[0016] (2) In the utility model, the water storage annular tube is arranged on the inner side of the air storage bag. When the air storage bag is inflated, the heat loss of the water storage annular tube to the outside can be reduced, which can effectively avoid the influence of the ambient temperature on the warm water in the water storage annular tube and prevent it from cooling down too quickly. Therefore, the liquid in the infusion bag can be preheated for a long time, thereby improving the liquid resuscitation effect.

[0017] (3) The mesh bag provided in the utility model can, on the one hand, position the infusion bag when it is not inflated and pressurized, and on the other hand, prevent the infusion bag from falling off the long strip due to the gradual reduction of the liquid in the infusion bag, which results in the pressure of the air storage bag in the long strip being insufficient to clamp the infusion bag.

[0018] (4) The temperature sensor and digital display screen provided in the present invention make it easy for medical staff to understand the water temperature in the water storage annular tube so that the water can be replaced in time when the water temperature drops below 30°C.

[0019] (5) The water storage annular tube in the utility model is composed of an S-shaped distribution pipeline. After the warm water is injected, it can ensure that the warm water is evenly distributed on the inner side of the long strip, thereby achieving a good preheating effect after contacting the infusion bag.

[0020] (6) The water injection port of the water injection pipe in the utility model is designed to be a conical port, which is convenient for medical staff to inject warm water into the water storage annular tube.

[0021] In summary, the utility model is easy to use, safe and reliable, has the dual functions of heating and pressurizing, and is suitable for use in rapid and large-volume infusion or blood transfusion in various clinical departments such as operating rooms and emergency departments.
