Description

Technical Field

[0001] The invention relates to the technical field of hemostasis emergency, in particular to an artery compression hemostasis device used in an emergency rescue center. Background Art

[0002] Application No. CN202410100868.2 discloses a limb artery compression hemostasis device for emergency treatment, including a vertical plate, a fixed plate, a support plate, a joystick, a pressing plate, a wound pressing mechanism, a linkage assembly, an arc adjustment assembly and a clamping mechanism; it solves the problem that when patients have different body shapes, the upper arc plate and the lower arc plate cannot clamp the patient's injured limbs; in addition, the diameters of the patient's upper and lower limbs are also inconsistent, so the upper arc plate and the lower arc plate cannot be applied to the patient's upper and lower limbs at the same time, which has limitations.

[0003] During emergency rescue, arterial rupture and bleeding is a life-threatening emergency situation that requires rapid and effective hemostasis measures. At present, clinical practice mainly relies on medical staff to press and stop bleeding with their bare hands. This method has significant defects: on the one hand, manual pressing requires continuous force, which can easily lead to physical exhaustion of medical staff, especially in long-term rescue, which may affect the pressing effect due to fatigue; on the other hand, when manually stopping bleeding, medical staff cannot free their hands to perform other key rescue operations, such as establishing intravenous channels, drug injections, etc., which delays the overall rescue efficiency. In addition, although traditional tourniquets and the above-mentioned patents can fix and apply pressure, they lack pressure regulation and hemostasis status monitoring functions, and there is a risk of incomplete hemostasis or excessive compression leading to tissue damage. Therefore, there is an urgent need for a device that can replace manual compression, achieve precise and controllable compression hemostasis, and have a hemostasis effect feedback function. Summary of the invention

[0004] In order to overcome the defects in the prior art, the purpose of the present invention is to provide an arterial compression hemostasis device for emergency rescue centers to solve the problems raised in the above background technology.

[0006] As a further improvement of the present technical solution, the lower end opening of the blood guide groove is away from the bottom center of the hemostatic ball, the blood collecting sleeve is cylindrical and has a blood collecting cavity on its top surface, the blood collecting cavity extends to above the bottom of the blood collecting sleeve, and the bottom surface of the blood collecting cavity is circular with a number of blood collecting ports at equal intervals for introducing blood seeping from the blood guide groove.

[0007] As a further improvement of the technical solution, the blood collecting cotton sleeve is arranged in the blood collecting cavity, and the bottom surface of the blood collecting cotton is provided with a plurality of protrusions at equal intervals in a circular shape, and the plurality of protrusions are correspondingly snap-fitted with a plurality of blood collecting ports.

[0008] As a further improvement of the technical solution, a threaded wall is provided on the top inner wall of the blood collecting sleeve, an adjusting rod is embedded in the top center of the hemostatic ball, and a threaded ring threadedly connected to the threaded wall is sleeved on the top of the adjusting rod.

[0009] As a further improvement of the technical solution, the top surface of the pressing cylinder is open and is slidably sleeved with the blood collecting sleeve, the middle outer wall of the blood collecting sleeve is provided with a ring platform slidably sleeved with the inner wall of the pressing cylinder, and a compression spring is provided between the top of the pressing cylinder and the ring platform.

[0011] As a further improvement of the technical solution, the longitudinal section of the belt pressing sleeve is L-shaped and a spring is arranged on the top surface of the vertical section, a threaded sleeve is arranged on the top surface of the spring, and an external thread threadedly connected to the threaded sleeve is opened on the top outer wall of the belt pressing sleeve.

[0012] As a further improvement of the technical solution, a protective layer is bonded between the threaded sleeve and the vertical section of the pressure belt sleeve, the protective layer is a soft material, and the bottom of the pressure cylinder is provided with a sealing sleeve, which is made of a water-absorbing material.

[0013] As a further improvement of the technical solution, the tape is made of stainless steel in the shape of a long sheet and its top surface is a concave arc surface. The outside of the tape is wrapped with a soft plastic layer, and a sleeve connected to the preload pin is sleeved in the through hole.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The arterial compression hemostasis device used in the emergency rescue center adopts a combination design of an elastic pressure cylinder and an adjustable tightening part to achieve hemostasis with an elastic pressure hemostatic ball, replacing manual continuous compression; the tape can be quickly adapted to different limb or neck sizes through the locking mechanism of the pre-tightening pin and the through hole, ensuring that the pressure is stably transmitted to the hemostatic part, allowing medical staff to free their hands for other rescue operations, significantly improving the efficiency of treatment.

[0016] 2. The arterial compression hemostasis device used in the emergency rescue center forms a multiple monitoring system by adopting a transparent silicone hemostatic ball, a blood drainage groove and a blood collecting cotton. When the contact area of ​​the hemostatic ball is gradually reduced by rotating the adjustment rod, if the blood collecting cotton continues to turn red after the blood drainage groove is exposed, it can be intuitively judged that the hemostasis is not complete, avoiding direct pressure withdrawal that may cause secondary heavy bleeding; at the same time, the silicone hemostatic ball can evenly disperse the pressure and reduce the risk of local tissue damage.

[0017] 3. The arterial compression hemostasis device used in the emergency rescue center is designed with customized specifications. The hemostasis parts, pressing parts and tightening parts can be adapted to limbs or necks of different thicknesses. The elastic compensation of the elastic band in the pre-tightening part ensures that the pressure process can effectively stop bleeding and avoid excessive compression. The progressive lifting function of the adjustment rod realizes the refined control of the hemostasis pressure and ensures the safety of the pressure removal process.

[0018] 4. The arterial compression hemostasis device used in the emergency rescue center adopts a modular design that integrates hemostasis, pressure and fixation functions. During operation, it only needs to aim at the bleeding point, tighten the tape and lock the pre-tightening pin to complete the hemostasis work, which greatly shortens the rescue preparation time; the blood collection sleeve and blood collection cotton can collect seeping blood, reduce blood contamination of the surgical area, maintain a clean surgical environment, and create favorable conditions for subsequent treatment.
