Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary equipment, in particular to an intelligent compression device for puncture points. Background Art

[0002] Lower limb artery surgery is an important type of vascular surgery, mainly used to treat stenosis, occlusion or other lesions of the lower limb arteries and restore blood supply to the limbs. This type of surgery usually includes endarterectomy, arterial bypass surgery, stent implantation, etc., aiming to dredge blocked arteries, improve blood circulation in the lower limbs, and prevent necrosis and amputation. The specific method and complexity of the surgery depend on the location, range and severity of the lesion, and the patient's overall health status and risk tolerance must be considered comprehensively.

[0003] In the lower limb artery surgery of vascular surgery, because the puncture point is in the groin area, the puncture point in the groin area needs to be pressurized to stop bleeding for 24 hours after the operation. However, the existing groin pressure hemostasis uses a bandage to stop bleeding. The groin is tied tightly for a long time, which affects the blood circulation of the lower limbs. In addition, the patient needs to lie flat for a long time, which is easy to form pressure sores at the tied area. Summary of the invention

[0004] The purpose of the present invention is to provide an intelligent compression device for puncture points to solve the technical problems raised in the above-mentioned background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions.

[0006] An intelligent compression device for puncture points comprises a fixing pad, a hemostatic pad and a compression airbag, wherein a flexible sleeve is fixedly connected to the lower surface of the fixing pad, an adhesive layer is arranged around the flexible sleeve on the lower surface of the fixing pad, an insertion hole communicated with the flexible sleeve is arranged on the upper surface of the fixing pad, the hemostatic pad is fixed on the lower end surface of the flexible sleeve, the compression airbag is arranged in the flexible sleeve, and when the compression airbag is inflated, it can expand and extend vertically downward, and a fastening mechanism is arranged on the fixing pad, and the fastening mechanism is used to fasten and limit the compression airbag in the flexible sleeve.

[0007] The fixing pad is adhered to the patient's skin by using the adhesive layer, and the position of the hemostatic pad is ensured to correspond to the position of the hemostatic point. Subsequently, the compression airbag is inflated, and the compression airbag expands and extends downward when inflated, pushing the hemostatic pad to be pressed against the hemostatic point, thereby achieving effective compression and hemostasis, and avoiding long-term excessive tightening of the patient's thigh to cause poor blood flow and pressure sores in the lower limbs. The structural layout is reasonable and the practicability is high. When the compression airbag is placed into the flexible sleeve through the insertion hole, the compression airbag can be restrained and limited in the flexible sleeve by using the fastening mechanism to prevent the compression airbag from falling out upward, thereby ensuring that the compression airbag can expand and extend downward when inflated, so as to provide an effective compression effect.

[0008] Preferably, the fastening mechanism includes a pair of fastening straps and a pair of limiting sleeves, one end of the two fastening straps are respectively fixedly connected to the surface of the fixing pad, the two limiting sleeves are fixed on the surface of the fixing pad and correspond one to one to the positions of the two fastening straps, and the two fastening straps are fixed with a mother Velcro and a child Velcro. When the compression airbag is fastened and limited in the flexible sleeve, the two fastening straps are perpendicular to each other and form a cross-shaped structure.

[0009] The compression airbag is bound in the flexible sleeve by a fastening belt, which has a detachable effect. Since the compression airbag is placed in the flexible sleeve, it has no direct contact with the hemostatic pad and the patient's skin. Combined with the detachable effect of the compression airbag, it is easy to disassemble and disinfect the compression airbag for reuse, thereby reducing the waste of medical resources.

[0010] Preferably, the top surface of the compression airbag is provided with an inflation tube, a one-way valve is installed in the inflation tube, and the flow direction of the one-way valve is from the inflation tube to the inside of the compression airbag.

[0011] Preferably, a pressure sensor is provided at the top of the compression airbag and extends into the compression airbag, which is used to detect the pressure in the compression airbag in real time. A pressure display screen is provided at the top of the compression airbag on one side of the pressure sensor, which is used to display the pressure data detected in the compression airbag.

[0012] Preferably, the top of the compression airbag has an exhaust port, an electric exhaust valve is installed in the exhaust port, a controller is provided on the top of the compression airbag, the electric exhaust valve is controlled by the controller, and a wireless communication module is provided on the top of the compression airbag for wirelessly transmitting control command signals.

[0013] Preferably, a battery is also provided on the top of the compression airbag, and the battery is a rechargeable battery used to supply power to the power unit of the device.

[0014] Preferably, the pressure sensor and pressure display screen are arranged in functional area A on the top of the compression airbag, the controller and wireless communication module are arranged in functional area B on the top of the compression airbag, the inflation tube and exhaust port are arranged in functional area C on the top of the compression airbag, and the battery is arranged in functional area D on the top of the compression airbag.

[0015] Preferably, a first snap-in position is formed between functional area A and functional area D and functional area B and functional area C for one of the fastening belts to fit in, and a second snap-in position is formed between functional area A and functional area B and functional area C and functional area D for the other fastening belt to fit in, and the first snap-in position and the second snap-in position intersect vertically to form a cross-shaped structure.

[0016] Through the functional zoning design, the space can be better planned, and each functional module can be reasonably laid out, thereby improving the utilization efficiency of the space. At the same time, the electromagnetic interference or other forms of mutual influence between the functional modules can be reduced, and the stability and reliability of the equipment can be improved. At the same time, a first snap-in position and a second snap-in position for the two fastening belts to fit in are formed between the functional areas, thereby avoiding the blocking and interference effects of the various functional structures on the fastening belts, ensuring that the two fastening belts can be pressed as tightly as possible on the compression airbag, and improving the stability of the compression airbag during compression and hemostasis.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows.

[0018] 1. The present invention utilizes an adhesive layer to adhere the fixing pad to the patient's skin and ensures that the position of the hemostatic pad corresponds to the position of the hemostatic point. Subsequently, the compression airbag is inflated, and the compression airbag expands and extends downward, pushing the hemostatic pad to be pressed against the hemostatic point, thereby achieving effective compression hemostasis and avoiding prolonged excessive tightening of the patient's thigh to cause poor blood flow in the lower limbs and pressure sores. The structure layout is reasonable and the practicability is high.

[0019] 2. The present invention utilizes a fastening belt to bind the compression airbag in a flexible sleeve, which has a detachable effect. Since the compression airbag is placed in the flexible sleeve, it does not come into direct contact with the hemostatic pad and the patient's skin. Combined with the detachable effect of the compression airbag, it is convenient to disassemble and disinfect the compression airbag for reuse, thereby reducing the waste of medical resources.

[0020] 3. The present invention can detect the air pressure in the compression airbag through the pressure sensor, and display the detected value on the pressure display screen, so that medical staff can timely grasp the degree of compression on the patient's hemostasis point. The controller controls the electric exhaust valve passage to release the gas in the compression airbag to achieve pressure relief. In the process of compression hemostasis, the compression airbag is controlled to gradually relieve pressure, thereby ensuring that the degree of compression becomes smaller and smaller, which is convenient for intelligent adaptive adjustment according to the degree of hemostasis completion.

[0021] 4. The present invention can better plan the space through functional zoning design, so that various functional modules can be reasonably laid out, improving the utilization efficiency of the space, and at the same time can reduce electromagnetic interference or other forms of mutual influence between functional modules, thereby improving the stability and reliability of the equipment. At the same time, a first snap-in position and a second snap-in position for the two fastening belts to fit in are formed between the functional areas, thereby avoiding blocking and interfering effects of various functional structures on the fastening belts, ensuring that the two fastening belts can be pressed as tightly as possible on the compression airbag, thereby improving the stability of the compression airbag during compression and hemostasis.
