Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a pressurized tourniquet. Background Art

[0002] Arterial blood sampling is a very common nursing operation in the ICU ward. Since the blood collected is from the arterial blood, it is particularly important to apply pressure to stop bleeding and prevent local skin cyanosis. The ICU ward is a special care ward with no family members accompanying the patient, only medical staff. After collecting arterial blood, pressing to stop bleeding can only be done by nurses. A patient must be pressed for at least minutes. If the coagulation mechanism is not good, the pressing time will be increased, saving time for nursing staff so that they have more time to complete other tasks. It can also avoid cyanosis of the skin at the puncture site and local hematoma caused by short pressing time. Utility Model Content

[0003] The utility model provides a pressurized tourniquet, which inflates the gas filling cavity inside the tourniquet by squeezing a rubber ball, thereby achieving a pressurized hemostasis function for the wound, saving nursing staff's time and reducing the risk of skin cyanosis and hematoma at the puncture site.

[0004] In order to solve the above technical problems, the technical solution provided by the utility model is: a pressurized tourniquet, comprising:

[0005] The belt body has a round wool veneer sewn on one end and a binding strap sewn on the other end, and a bristle veneer with a specification matching the round wool veneer is sewn on the binding strap; a gas filling cavity is arranged in the belt body, and the gas filling cavity is connected to a rubber ball for pressurization through an air guide tube;

[0006] An air guide tube, one end of which is inserted into the gas filling cavity of the belt body and fixed therein, and the other end of which is connected to a rubber ball with an air valve;

[0007] The rubber ball has an air valve at its end, the interface of the air valve is connected to the end of the airway tube, and the rubber ball squeezes and delivers gas through the air valve and the airway tube into the gas filling cavity of the belt body, thereby realizing the pressurized hemostasis function of the belt body.

[0008] Compared with the prior art, the utility model has the following advantages: 1) Rapid hemostasis: by squeezing the rubber ball, the gas filling cavity of the belt body is quickly inflated to achieve rapid pressurization hemostasis of the wound;

[0009] 2) Adjustable pressure: By adjusting the force of squeezing the rubber ball, the pressure inside the belt can be accurately controlled to meet the pressure requirements of different wounds;

[0010] 3) Firm fixation: The bonding method of the bristle veneer and the round bristle veneer allows the belt to fit tightly on the wound and is not easy to loosen or fall off;

[0011] 4) Comfortable and breathable: The belt body is made of soft and breathable material to ensure that it will not cause discomfort to the patient's skin during long-term use;

[0012] 5) Save time: Using this compression tourniquet can significantly reduce the nurse's compression time, so that there is more time to complete other tasks;

[0013] 6) Reduce risks: Precise pressure hemostasis can reduce the risk of bruising and hematoma at the puncture site. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0019] Embodiment 1

[0020] like Figure 1 and Figure 2 As shown, in this embodiment, a pressurized tourniquet is provided, which mainly includes the following components:

[0021] 1. Belt body 1

[0022] The belt body 1 is made of a soft, durable and breathable material, such as medical grade silicone or rubber material, to ensure that it does not cause discomfort to the patient's skin during long-term use. A gas-filled chamber is provided inside the belt body 1, which is a sealed space for storing gas to achieve the function of pressurized hemostasis. The design of the gas-filled chamber takes into account the uniform distribution of pressure to ensure that no unnecessary pressure is caused to the wound during the pressurization process. A round fleece veneer 6 is sewn on one end of the belt body 1, and the round fleece veneer 6 uses a medical grade adhesive to ensure that it fits tightly to the skin and is not easy to fall off. A bandage 2 is sewn on the other end, and the length and width of the bandage 2 are carefully designed to adapt to wounds of different sizes and different patient body shapes.

[0023] 2. Binding strap 2 and bristle veneer 3

[0024] The strap 2 is sewn with a bristle veneer 3 of a specification matching the round bristle veneer 6. The bristle veneer 3 is a material with a fine hook-shaped structure, which can be tightly hooked with the fine fibers on the round bristle veneer 6 to achieve the fixation of the strap body 1. This design is not only easy to operate, but also firmly fixed and not easy to loosen.

[0025] 3. Airway 4

[0026] The airway tube 4 is made of medical grade silicone material, which is soft and durable, has a certain elasticity, and can adapt to connections at different angles and directions. One end of the airway tube 4 is inserted into the gas filling cavity of the belt body 1 and fixed by a special process to ensure that it will not fall off or leak during the inflation process. The other end is connected to the rubber ball 5, and the connection method adopts a standard medical interface to ensure that the connection is firm and easy to replace.

[0027] 4. Rubber ball 5

[0028] The rubber ball 5 is made of medical grade rubber material and has good elasticity and durability. The end of the rubber ball 5 is matched with an air valve, and the interface of the air valve is connected to the end of the airway tube 4 through a standard medical interface. The design of the air valve takes into account the anti-leakage function to ensure that the gas will not leak during the inflation process.

[0029] By squeezing the rubber ball 5, the gas can be delivered to the gas filling cavity of the belt body 1 through the gas valve and the air guide tube 4. The squeezing force of the rubber ball 5 can be controlled by adjusting the squeezing degree, thereby realizing accurate control of the internal pressure of the belt body 1. This design makes the use of the pressurized tourniquet more flexible and convenient.

[0030] Embodiment 2

[0031] Based on the first embodiment, Figure 1 and Figure 3 As shown, in actual application, the belt body 1 is firstly wrapped around the arterial blood collection site to ensure that the round hair veneer 6 and the thorn hair veneer 3 are in the appropriate position. Then, by squeezing the rubber ball 5, the gas is transported to the gas filling cavity of the belt body 1 through the gas valve and the air guide tube 4, so that the belt body 1 expands and applies pressure to the wound, thereby achieving the effect of hemostasis. Since the design of the gas filling cavity takes into account the uniform distribution of pressure, it can be ensured that no unnecessary pressure is caused to the wound during the pressurization process.

[0032] When the pressure of the tourniquet needs to be adjusted, it can be achieved by continuing to squeeze the rubber ball 5 or relaxing the rubber ball 5. In addition, since the design of the rubber ball 5 and the air valve takes the anti-leakage function into consideration, it can be ensured that the gas will not leak during the inflation process.

[0033] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and the description are only to illustrate the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
