Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to an electrically adjustable femoral artery compressor. Background Art

[0002] After femoral artery puncture, rapid hemostasis is required. Some existing clinics use manual compression to stop bleeding, which is not only troublesome, but also has a chance of unsuccessful hemostasis due to manual operation. The medical femoral artery compressor is a device that compresses the puncture point to stop bleeding, assisting the puncture point to stop bleeding and heal quickly.

[0003] The Chinese utility model with publication number CN213047115U discloses a hemostat, including a pressure plate body and a fixing assembly. The front end of the pressure plate body is provided with a compression head, a silicone pad installed at one end of the compression head, and a driving assembly arranged at the other end of the compression head. The silicone pad is an arc-shaped structure that protrudes outward on the side facing away from the compression head and gradually shrinks toward the compression head. By setting the driving assembly, the compression head can be driven to rise and fall, so as to achieve compression hemostasis at the puncture point of the femoral artery of the patient's thigh; by providing a silicone pad on the compression head, and the silicone pad is in an arc-shaped structure, the silicone pad is adapted to the shape of the patient's thigh, so as to avoid excessive pressure on non-puncture point parts during compression hemostasis to cause hematoma.

[0004] Although the above-mentioned hemostat can also compress and stop bleeding at the femoral artery puncture point, its compression head needs to be raised and lowered by manual rotation, which is inefficient and cumbersome to operate. Moreover, the overall position of the compression head and the hemostat is fixed and cannot be flexibly adjusted according to the patient's body shape, and cannot be well adapted to patients of different body shapes. Summary of the invention

[0005] The purpose of the utility model is to solve the problems mentioned in the background technology and to provide an electrically adjustable femoral artery compressor, which does not require manual adjustment of the compression force, is easy to operate, can adapt to patients of different body shapes, and can also improve patient comfort.

[0006] In order to achieve the above technical purpose, the technical solution adopted by the utility model is:

[0007] An electrically adjustable femoral artery compressor comprises a base plate, a restraining mechanism, a compression mechanism and a support seat, wherein a mounting cavity is provided inside the front end of the base plate, the compression mechanism is provided with a mounting rod matching the mounting cavity, the mounting rod is bolted to the mounting cavity, and a plurality of through holes matching the bolts are provided on the mounting rod; the compression mechanism is provided with a retractable compression member for compressing the femoral artery;

[0008] The binding mechanism and the support seat are arranged at the bottom of the base plate, and the support seat is provided with an arc surface matching the leg; the binding mechanism is not located behind the support seat, and the binding mechanism is used to detachably connect the base plate to the leg.

[0009] Preferably, the compression mechanism comprises a frame, an electric cylinder is provided on the top of the frame, and a telescopic rod of the electric cylinder is connected to the compression piece.

[0010] Preferably, the telescopic rod of the electric cylinder passes through the top of the frame and is connected to the axle seat inside the frame. A pressure plate is provided at the bottom of the axle seat. Both sides of the pressure plate are slidably connected to the inner wall of the frame. A connecting rod is provided at the bottom of the pressure plate. The connecting rod passes through the bottom of the frame and is connected to the pressure piece.

[0011] Preferably, sliders are provided on both sides of the pressing plate, and slide rails matching the sliders are provided on the side walls of the frame.

[0012] Preferably, a plurality of sliding rods are provided in the frame, and the sliding rods penetrate through the pressure plate and are slidably connected to the pressure plate; the sliding rods are parallel to the telescopic rods of the electric cylinder.

[0013] Preferably, a first buffer pad is provided on the arcuate surface of the support seat, and a second buffer pad is provided on the bottom of the pressure member.

[0014] Preferably, the restraining mechanism comprises two restraining belts respectively arranged on the left and right sides of the base plate, and the ends of the restraining belts are respectively provided with matching buckles and sockets.

[0015] Preferably, the restraining mechanism is arranged in front of the supporting seat.

[0016] Preferably, a pull ring is provided on the top of the substrate.

[0017] Preferably, the compression member is provided with a curved surface matching the leg.

[0018] The beneficial effects of the utility model are:

[0019] 1. The compression mechanism is detachably connected to the base plate through a mounting rod. The overall length of the device can be adjusted to accommodate patients of different body shapes (mainly leg length) by inserting the mounting rod into the mounting cavity of the base plate. Due to differences in patient body shapes, hemostats with fixed lengths cannot be well worn on the patient's legs for effective hemostasis (for example, if the patient has short legs, the support point of the hemostat may have to be placed on the knees or abdomen, which cannot provide firm and effective support, resulting in the compression head being unable to provide sufficient pressure for hemostasis). In contrast, the device has a wider applicability, and the length can be flexibly adjusted according to different patients. The appropriate length can be adjusted as needed (actually, the lever arm is adjusted), so that the pressure of the compression head remains unchanged while the support seat exerts less pressure on the human body, thereby improving the comfort of use for the patient.

[0020] 2. The pressing part of the pressing mechanism is driven by an electric cylinder, which is more labor-saving and more convenient to operate than manually twisting the pressing head for lifting and lowering. BRIEF DESCRIPTION OF THE DRAWINGS

The mounting rod 32 is bolted to the mounting cavity, and a corresponding through hole is provided at the front end of the base plate to penetrate the mounting cavity to allow the bolt to pass through; a plurality of through holes matching the bolts are provided on the mounting rod 32 from front to back (only two through holes are shown in the accompanying drawings, and more through holes can actually be designed). In this way, by selecting different through holes at the front and back to connect with the through holes at the front end of the base plate 1 for bolting to adjust the overall length of the device, it can better adapt to patients of different body shapes, and can also adjust the pressure of the support seat 4 on the human body (the principle will be described in detail below).

[0034] The restraining mechanism 2 and the support seat 4 are arranged at the bottom of the base plate 1, the support seat 4 is provided with an arc-shaped surface matching the legs, and the arc-shaped surface of the support seat 4 is provided with a first buffer pad; the restraining mechanism 2 is not located behind the support seat 4, that is, the restraining mechanism 2 can be arranged in front of the support seat 4, or it can be arranged at the same position as the support seat 4 (in terms of the front and rear position of the base plate 1, this arrangement is shown in the accompanying drawings), but it is preferably arranged in front of the support seat 4.

[0035] The binding mechanism 2 is used to detachably connect the base plate 1 to the legs. The binding mechanism 2 includes two binding straps 21 respectively arranged on the left and right sides of the base plate 1. The ends of the binding straps 21 are respectively provided with matching buckles 22 and sockets 23. The buckles and sockets commonly used on school bag straps can be used.
