Description

Technical Field

[0001] The invention relates to the technical field of medical supplies, in particular to an automatic inflatable tourniquet. Background Art

[0002] At present, the hemostasis methods used clinically include bandage hemostasis, manual inflatable tourniquet hemostasis and electric pneumatic tourniquet hemostasis, which still have the following defects:

[0003] 1. The bandage hemostasis method is generally used for emergency treatment of severe bleeding in the limbs. It achieves the purpose of hemostasis by compressing blood vessels and blocking blood flow. However, if used improperly or for too long, the tourniquet can cause ischemia and necrosis of the distal limbs. If the pressure is too low, it will not stop the bleeding.

[0004] 2. Manual inflatable tourniquets are mainly used for pre-hospital emergency treatment, patient transfer and examination. They are equipped with a pressure display device to monitor pressure and are easy to carry. However, they require manual operation by medical staff, which is not conducive to improving emergency treatment efficiency when there are a large number of people.

[0005] 3. Electric pneumatic tourniquets are mainly used in operating rooms. They have the functions of automatic pressurized hemostasis, automatic timing, instantaneous deflation, pressurized blood transfusion and pressurized flushing. However, they must use a power supply, the connecting tubes are prone to air leakage, there are strict usage specifications, they are inconvenient to operate and carry, and they are not easy to use for unexpected situations such as first aid.

[0006] Therefore, we propose an automated inflatable tourniquet to solve the above problems.

[0007] The above information disclosed in this background technology is only used to increase the understanding of the background technology of the present invention and therefore, it may include information that does not constitute the prior art known to ordinary technicians in this field. Summary of the invention

[0008] The object of the present invention is to provide an automated inflatable tourniquet to solve the problems raised by the above background technology.

[0009] To achieve the above object, the present invention provides the following technical solution: an automated inflatable tourniquet, comprising:

[0010] An automatic air pump, wherein a valve is provided at the far end of an air filling tube of the automatic air pump;

[0011] An air bag cuff, wherein a connecting pipeline of the air bag cuff is detachably connected to a valve, and a hemostatic clamp and a timing device are arranged on the connecting pipeline.

[0012] Preferably, a marking pocket is provided on the airbag cuff.

[0013] Preferably, the inflation tube comprises a rubber layer, a reinforcement protection layer and a nylon braided layer from the inside to the outside.

[0014] Preferably, the hemostatic clip is a Robert flow regulating clip.

[0015] Preferably, the automatic air pump has a built-in LED lighting lamp and a charging module.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) Automaticity: During the first aid process, the present invention uses an automatic inflation pump to inflate the airbag cuff. The automatic inflation pump displays accurate air pressure data, which can avoid failure to stop bleeding due to too low pressure or limb necrosis due to too high pressure;

[0018] (2) High efficiency: It is easy to remove the automatic inflation pump and perform hemostasis operations for multiple patients. It is simple to operate and easy to use. It can quickly rescue multiple patients, improve the work efficiency of medical staff, and grasp the golden emergency time;

[0019] (3) Convenience: small size and light weight, easy for emergency personnel to carry, and can be quickly inflated to stop bleeding;

[0020] (4) Comfort: The hemostatic clamp facilitates the adjustment of gas flow and the removal of the automatic inflation pump, thus reducing the patient's weight and ensuring the patient's comfort;

[0021] (5) The invention is low-cost, easily accepted, widely used, multifunctional, and meets the daily needs of the public;

[0022] (6) The marking card pocket is convenient for clinical use. The hemostasis time record card can be inserted into the card pocket to prevent it from being lost and secondary injury. The timing device can regularly remind medical staff to release air pressure and untie the tourniquet to prevent excessive pressure from causing necrosis of the patient's use site.

[0031] The airbag cuff 4 and the connecting pipeline 5 of the airbag cuff 4 are detachably connected to the valve 3 , and the connecting pipeline 5 is provided with a hemostatic clip 7 and a timing device 8 .

[0032] The hemostatic clip 7 can adjust the closure of the connecting pipeline 5. The timing device 8 can regularly remind the medical staff to release the air pressure and untie the airbag cuff 4 to prevent the necrosis of the patient's use part caused by excessive pressure.

[0033] Embodiment 2

[0034] See also Figure 1 , an automated inflatable tourniquet, comprising:

[0035] The automatic air pump 1 has an air filling pipe 2 whose far end is provided with a valve 3.

[0036] The automatic air pump 1 can accurately measure pressure and provide accurate data for reasonable control of air pressure during first aid, which can avoid failure to stop bleeding due to too low pressure or limb necrosis due to too high pressure, improve the first aid efficiency of medical staff, and grasp the golden first aid time; the automatic air pump 1 is small in size and light in weight, and is easy for first aid personnel to carry.

[0037] The automatic air pump 1 has built-in LED lighting and charging module, and can be used outdoors at night. In emergency, it can also be used as a power bank to meet outdoor needs. The air tube 2 is composed of a rubber layer, a reinforced protective layer and a nylon braided layer from the inside to the outside, which is anti-freeze and explosion-proof.

[0038] The airbag cuff 4 and the connecting pipeline 5 of the airbag cuff 4 are detachably connected to the valve 3 , and the connecting pipeline 5 is provided with a hemostatic clip 7 and a timing device 8 .

[0039] The hemostatic clip 7 adopts Robert flow regulating clip, which is made of ABS, has good acid and alkali resistance, corrosion resistance, heat resistance, will not rust or deform, is integrally molded, has no sharp edges, and can adjust the closure of the connecting pipe 5 by lightly pressing the thumb, without any safety hazards. The model with a tube outer diameter of 6-12mm is selected, which is suitable for the connecting pipe 5 of the airbag cuff 4.

[0040] The timing device 8 can regularly remind the medical staff to release the air pressure and untie the airbag cuff 4 to prevent necrosis of the patient's use part caused by excessive pressure.

[0041] The airbag cuff 4 is provided with a transparent marking pocket 6. When the airbag cuff 4 is used, the airbag cuff 4 needs to be in contact with the skin. If the time is too long, the skin may be damaged. If the time is too short, it may not be able to stop bleeding, resulting in excessive bleeding and shock to the patient. In order to prevent the medical staff or emergency personnel from forgetting the start time of hemostasis due to a large number of patients, a transparent marking pocket 6 is provided on the airbag cuff 4 to facilitate recording of time and prevent secondary injuries.

[0042] Working principle of this embodiment: When using the automatic inflatable tourniquet, first, wear the airbag cuff 4 on the patient's suitable hemostasis part, turn on the automatic air pump 1 to inflate the airbag cuff 4 for hemostasis, and the automatic air pump 1 can accurately measure the pressure and provide accurate data for the reasonable control of air pressure during the first aid process, which can avoid the inability to stop bleeding due to too little pressure or limb necrosis due to excessive pressure, improve the efficiency of medical staff's first aid work, and grasp the golden first aid time. The first aid starts with a timing device 8 to remind medical staff to release the air pressure in time and untie the airbag cuff 4 to prevent necrosis of the patient's use part due to excessive pressure. The closure of the connecting pipeline 5 is adjusted by the hemostatic clamp 7, and the automatic air pump 1 can be removed for other patients. During first aid, the time is recorded by the record card in the marking card pocket 6 to prevent secondary injuries.
