Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a hemostat after distal radial artery puncture. Background Art

[0002] The radial artery puncture technique is a new interventional surgical puncture technique developed in recent years. It is a new interventional approach and an effective supplement to the conventional approach. Clinical practice in recent years has shown that this technique is more operable and safer than traditional radial artery puncture in certain situations (including but not limited to: when conventional radial artery puncture fails (spasm, hematoma, etc.), when the radial artery pulse is unclear during secondary interventional surgery, when bilateral radial arteries are used to treat CTO, or when the radial artery is acute or chronic occluded).

[0003] Currently, there are a large number of radial artery hemostat with different structures and functional principles for postoperative hemostasis at the puncture point for traditional radial artery puncture technology. However, for distal radial artery puncture technology, since the distal radial artery puncture point is located on the hand and the surrounding hand structure is obviously conical, the existing radial artery hemostat products cannot be stably fixed at the puncture point, resulting in no convenient hemostatic device available for postoperative hemostasis.

[0004] For example, the Chinese patent with publication number CN111616769B discloses a distal radial artery hemostatic compressor. The distal radial artery hemostatic compressor includes a wrist ring, a thumb ring and a connecting structure, on which an inflatable airbag and a pressure sensing element are provided; it also includes a pressure controller, the pressure controller has a gripping surface for the palm to fit, and a control mainboard is provided in the pressure controller; the inflatable airbag is connected to an exhaust pipeline and an exhaust valve, the control mainboard is electrically connected to the pressure sensing element and the exhaust valve, and the control mainboard is used to control the interval opening of the exhaust valve to enable the inflatable airbag to work in a step-type pressure relief. The patient extends his wrist into the wrist ring and the thumb into the thumb ring, so that the connecting structure is just in the snuff bottle area, and the inflatable airbag exerts a compressive effect on the puncture point; the control mainboard adjusts the inflatable airbag to release pressure in a step-type manner, which can gradually reduce the pressure on the puncture point; prevents compression damage to the radial and ulnar nerves, and improves the freedom of movement of the wrist joint.

[0005] The above-mentioned hemostatic compressor is fixed on the human hand by a wrist ring, a thumb ring and a connecting structure. However, the hands of different patients are of different sizes, and the use needs of different patients cannot be met, which reduces the practicality of the hemostatic compressor. The existing hemostatic compressors all adopt the method of first pulling out the retention needle or puncture needle, and then the medical staff presses the hemostatic cotton at the needle hole position, and then wears the hemostatic compressor on the patient's hand. The process is very cumbersome and causes many inconveniences. Therefore, the present application provides a hemostatic device after distal radial artery puncture to meet the needs. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a hemostatic device after distal radial artery puncture to solve the problem that the existing hemostatic compressor cannot meet the use needs of different patients, which reduces the practicality of the hemostatic compressor; the existing hemostatic compressors all adopt the method of first pulling out the retention needle or the puncture needle, and then the medical staff presses the hemostatic cotton at the needle hole position, and then wears the hemostatic compressor on the patient's hand.

[0018] Compared with the prior art, the present invention has at least the following beneficial effects:

[0019] In the above scheme, a first fixing belt, a second fixing belt, a wool patch, a hook patch, a fixing base, an operation hole, an observation hole, a hemostasis component, and a plurality of fixed rubber seats are provided. When in use, the fixing base is first placed at the distal radial artery position, and the avoidance groove on the fixing base is located above the retention needle. The second fixing belt and the first fixing belt are wrapped around the back of the hand to the wrist position, and then adhered by the wool patch and the hook patch, and the third fixing belt is passed between the thumb and the index finger, and the hook patch is adhered to the wool patch on the back of the second fixing belt to achieve relative position fixation between the fixing base and the back of the patient's hand, thereby achieving relative position fixation between the fixing base and the back of the patient's hand, improving the fixing effect, and meeting the use needs of different patients, and having good practicality. By providing a pair of operation holes, one of the operation holes is used to pull out the puncture needle or the retention needle, and the other operation hole is used to press the needle hole with hemostatic cotton to stop bleeding, and the hemostatic component is driven to move by the driving component, and the hemostatic component is pressed at the needle hole position The hemostat is placed in the position, and the hemostatic cotton is taken out to press the needle hole to stop bleeding. The hemostat can be fixed at the distal radial artery position before the puncture needle or the retention needle is pulled out, and the retention needle or the puncture needle can be pulled out conveniently. There is no need to pull out the retention needle or the puncture needle first. When wearing the hemostat, the operation convenience is improved, and the wearing of the hemostat is convenient. By setting multiple first sliding bars and a first compression spring, the back of the hand can be compressed and fixed at multiple points. The first sliding bar can slide in the sliding hole, and the first compression spring provides a certain compression force, which prevents the ligament connected to the thumb from tilting up when the patient's hand or thumb is prying, thereby affecting the relative position fixation of the fixed base, further improving the fixing effect of the fixed base, and avoiding sliding. By setting an avoidance groove, the avoidance groove spans the distal radial artery position, which prevents the fixed base from exerting pressure on the place. By setting an observation hole, it is convenient for medical staff to observe during operation. The hemostat of the present application is symmetrically arranged to meet the needs of left and right hand use, and is worthy of large-scale promotion.

[0020] By setting a driving component and a hemostasis component, the threaded tube is rotated, and the threaded tube rotates on the guide tube, driving the screw to move downward under the action of the guide block and the guide groove. The downward movement of the screw drives the second slide bar, the fixed plate, the fixed box, and the hemostasis bag to move downward. The hemostasis bag contacts the needle hole, and as the screw continues to move, and with the elastic force of the second compression spring, the axis compresses the needle hole to stop bleeding. The operation is simple and convenient, and the hemostasis effect is good. The hemostasis bag can increase the contact area with the needle hole, increase the area of ​​compressed hemostasis, avoid using rigid materials for hemostasis, and improve the comfort during hemostasis. By setting the guide block and the guide groove, the screw does not rotate when it moves, avoiding driving the hemostasis bag to rotate, and twisting the skin on the back of the patient's hand to affect the hemostasis effect.

[0021] By setting up a disposable sterile cover, the hemostatic bag is prevented from directly contacting blood and causing contamination of the hemostatic bag, which facilitates the subsequent cleaning and disinfection of the hemostatic bag. In addition, the relative position of the disposable sterile cover and the fixing box is easily fixed through the shezi annular groove.

[0022] The anti-slip protrusion is provided to prevent the relative position of the hemostatic bag and the skin from moving when the thumb moves, thereby improving the hemostatic effect.

[0023] By setting the weakened groove and the fixed base to be made of elastic rubber material, the fixed base can have a certain amount of deformation at the position of a pair of weakened grooves, so that the multiple fixed rubber seats on both sides can better fit with the two sides of the back of the hand at the distal radial artery position, meet a certain curvature, and improve the fixing effect.
