Description

Technical Field

[0001] The utility model relates to the field of medical machinery, in particular to a self-decompression liquid sac type arterial tourniquet. Background Art

[0002] Clinically, for patients undergoing non-interventional treatment in the operating room or other departments, such as intensive care patients and critical surgery patients, continuous blood pressure monitoring is required, and arterial pressure measurement is usually used, that is, a puncture needle with a thinner needle is inserted into the artery, and then connected to an arterial pressure measuring device to instantly measure changes in arterial blood pressure. After the treatment is completed and the puncture needle is removed, the patient needs to stop bleeding in time. The duration of hemostasis varies according to the patient's coagulation state, usually 15 to 20 minutes. During the pressing process, the pressing pressure needs to be gradually reduced; for patients undergoing interventional treatment in the cardiology department and interventional room, such as patients undergoing coronary heart disease intervention and vascular intervention, a thicker puncture needle is usually used for interventional puncture at the radial artery or femoral artery. During the operation, an anticoagulant will be injected. After the treatment is completed and the puncture needle is removed, the patient usually stops bleeding for 6 to 10 hours. During the pressing process, the pressing pressure needs to be gradually reduced.

[0003] Traditional hemostasis methods include manual compression and bandage dressing. The time required for hemostasis after different surgeries varies greatly. The use of manual compression hemostasis increases the workload of medical staff, while the use of bandage dressing has problems such as the inability to directional pressurization or decompression, invisible bleeding at the puncture point, edema easily occurring if the bandage time is too short, and arterial occlusion, limb ischemia, edema, and pain complications easily occurring if the bandage time is too long. Existing hemostasis equipment generally uses constant pressure to press the puncture hemostasis point to achieve the purpose of hemostasis, such as a mechanical spiral compression tourniquet, or uses electronic equipment for inflation and pressurization, such as a digital radial artery hemostasis device disclosed in patent number 201620454734.1.

That is to say, by controlling the capacity of water in the liquid sac 3, the pressure of the transparent interlayer 2 on the puncture hemostasis point can be controlled.

[0038] As a preferred embodiment, the water injection valve 5 and the water outlet limiting tube 6 are respectively located on the front side of the tourniquet body 1; the liquid tube 4 is fixed on the front side of the liquid capsule 3, and the middle part of the liquid tube 4 and the middle part of the liquid capsule 3 are jointly provided with a connecting hole 401, and the liquid tube 4 and the liquid capsule 3 are connected through the connecting hole 401. When the medical staff injects water into the water injection valve 5, the water flows into the liquid capsule 3 through the liquid tube 4 and the connecting hole 401 in sequence. After the tourniquet is fastened, when the medical staff opens the water outlet limiting tube 6, the water in the liquid capsule 3 flows out according to the flow of the liquid tube 4. The liquid passes through the connecting hole 401 and the liquid tube 4 and flows out from the water outlet end 6b of the water outlet limiting tube 6; one end of the liquid tube 4 extends out of the transparent layer 201 and is connected with the water injection valve 5, and the other end of the liquid tube 4 extends out of the transparent layer 201 and is connected with the water outlet limiting tube 6, wherein the two connection points between the liquid tube 4 and the transparent layer 201 are fixedly connected, so that the gas chamber 2a is a sealed gas chamber 2a, and no gas exchange is performed with the outside, thereby ensuring that the pressure in the liquid bag 3 is the pressure of the transparent interlayer 2 on the puncture hemostasis point.

For example, the inner diameter of one water outlet flow limiting tube 6 is a1mm, and the flow rate is b1ml / h, and the inner diameter of another water outlet flow limiting tube 6 is a2mm, and the flow rate is b2ml / h. When a1>a2, then b1> b2, and each water outlet flow limiting tube 6 is arranged in sequence according to the size of the inner diameter, so that it is convenient to select the water outlet flow limiting tube 6 of the appropriate type; the water inlet end 6a of each water outlet flow limiting tube 6 is connected to the other end of the liquid pipe 4, and each water outlet flow limiting tube 6 is provided with a water stop clamp 601, and one or several of the water outlet flow limiting tubes 6 can be opened by the water stop clamp 601 to achieve the required flow rate.

The inner diameter of the second water outlet flow limiting tube 6 is a3mm, The flow rate is 2b1ml / h, the inner diameter of the third water outlet limiting tube 6 is a4mm, and the flow rate is 3b1ml / h. When stopping bleeding at the puncture hemostasis point of a non-invasive treatment patient, the hemostasis time is usually 15 to 20 minutes. The medical staff can first inject b1ml of water into the liquid capsule 3 through the water injection valve 5, and then open the water outlet limiting tubes 6 with a flow rate of b1ml / h and 2b1ml / h at the same time, or open the water outlet limiting tubes 6 with a flow rate of b1ml / h and 3b1ml / h at the same time. After pressing for 15 to 20 minutes, the liquid capsule 3 is filled with water. All the water in the liquid sac 3 flows out through the corresponding water outlet limiting tube 6. During the pressing period, the pressure gradually decreases to zero, thereby achieving the effect of complete hemostasis. When stopping bleeding at the puncture hemostasis point of an interventional treatment patient, the hemostasis time is usually 6 to 10 hours. The medical staff can first inject 6 to 10b1ml of water into the liquid sac 3 through the water injection valve 5, and then open the water outlet limiting tube 6 with a flow rate of b1ml / h. After pressing for 6 to 10 hours, all the water in the liquid sac 3 flows out through the corresponding water outlet limiting tube 6.

[0041] As a preferred embodiment, the self-decompression liquid bag assembly also includes a plurality of fixing straps 603, each fixing strap 603 corresponds to each water outlet flow limiting tube 6 one by one, the middle part of each fixing strap 603 is respectively wrapped around the corresponding water outlet flow limiting tube 6, and the two ends of each fixing strap 603 are fixedly connected to the front side of the tourniquet body 1 to position each water outlet flow limiting tube 6.

The pressure in the liquid bag 3 is equal to the pressure of the transparent interlayer 2 on the puncture hemostasis point. For example, when the water in the liquid bag 3 is 10b1ml, the pressure in the liquid bag 3 is c1mmHg. For interventional treatment patients who have a puncture at the radial artery and need to press the puncture hemostasis point for 10h, a pressure of c1mmHg needs to be applied at the beginning. The medical staff can first inject 10b1ml of water into the liquid bag 3 through the water injection valve 5, and then open the water outlet limiting tube 6 with a flow rate of b1ml / h at the same time.
