Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a compressor used for distal radial artery puncture points. Background Art

[0002] Distal radial artery puncture technology is a new interventional surgical puncture technology developed in recent years. It is a new interventional approach and an effective supplement to conventional approaches. Clinical practice in recent years has shown that this technology 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); at the same time, because the patient's hands can be naturally placed on the abdomen during the operation, it brings better comfort to the patient and makes the operation more convenient for the operator. In addition, clinical data show that the distal radial artery puncture technology reduces puncture site complications, reduces bed rest time, and increases treatment comfort compared to traditional radial artery puncture.

[0003] In addition, the radial artery is located between the thumb and index finger above the human wrist. It is more difficult to fix and compress it than the proximal radial artery. Generally, overlapping gauze is needed to compress the puncture point after surgery to stop bleeding from the postoperative wound. There is currently no dedicated instrument on the market. Doctors generally use the traditional bandage wrapping method, which is not convenient for operation and postoperative observation. At the same time, due to the need for compression cycle, continuous high-pressure compression can easily cause patient discomfort and even injuries such as pressure blisters.

[0004] Therefore, in summary, there is an urgent need for a distal radial artery puncture point compressor that can fix and adjust the distal thumb and index finger, accurately compress the distal radial artery, reduce the risk of bleeding, and improve patient comfort. Summary of the invention

[0034] Example

[0035] Please see attached Figure 1-3 As stated, attached Figure 1 Schematic diagram of the structure of the compressor for distal radial artery puncture point in the embodiment of the utility model; Figure 2 : is a schematic diagram of the structure of the fixed base and the finger restraint belt in the embodiment of the utility model; Figure 3It is an implementation diagram of the compressor for distal radial artery puncture point described in the embodiment of the utility model.

[0036] This device mainly solves the problem of accurately compressing the puncture point after distal radial artery puncture surgery, reduces the risk of bleeding, and increases the patient's postoperative comfort. For this purpose, a compressor for the distal radial artery puncture point is specially designed.

[0037] like Figure 1 , Figure 2 As shown, the device includes a fixed base 1, an elastic fixing belt 2, a finger restraint belt 3 and a pressurizing component 4; wherein, fixing ears 5 are respectively extended outward from the middle positions of both ends of the fixed base 1; correspondingly, long holes 6 are penetrated on the fixing ears 5 at both ends; and the elastic fixing belt 2 and the finger restraint belt 3 are respectively sleeved in the long holes 6 of the fixing ears.

[0038] Correspondingly, Velcro 7 is provided on both the front and back surfaces of the elastic fixing belt 2, and the length of the elastic fixing belt 7 used in the present device is set to be long enough so that it can be easily wrapped around and adhered to the patient's wrist, thumb and index finger to form a fixation.

[0039] Correspondingly, the finger restraint belt 3 is in a U-shaped structure as a whole, and the finger restraint belt 3 is provided with an index finger restraint opening 31 and a thumb restraint opening 32 for sleeved index finger and thumb, respectively; wherein, the shapes of the index finger restraint opening 31 and the thumb restraint opening 32 are both correspondingly fitted to the index finger and thumb of the patient; in addition, a finger inlet 33 is also provided on the finger restraint belt 3, and the finger inlet 33 is interconnected with the index finger restraint opening 31 and the thumb restraint opening 32. When using the finger restraint belt 3, the patient can sequentially pass the thumb and index finger through the finger inlet 33, and through the corresponding thumb restraint opening 32 and index finger restraint opening 31, so that the finger restraint belt 3 is fixed on the patient's thumb and index finger, thereby forming fixed compression in cooperation with the elastic fixing belt.

[0040] In this embodiment, the finger restraint belt 3 is made of an adhesive material (containing a bristle adhesive structure) and can be adhesively fixed with the elastic fixing belt 2 (the position can be adjusted appropriately according to the thickness of the finger, and the tail end of the elastic fixing belt 2 can be passed around the wrist to the back of the hand through the inside). Correspondingly, the finger restraint belt 3, the elastic fixing belt 2 and the mother-and-child Velcro 7 are all made of soft and skin-friendly materials, so that the patient's comfort when using it can be improved when pressurized and fixed.

[0041] Correspondingly, in the present embodiment, the fixed base 1 is of a rectangular structure and is transparent as a whole. Its transparent nature allows for direct observation of the compression hemostasis, making the compression of the distal radial artery puncture point more intuitive.

[0042] Correspondingly, a threaded hole 8 is also provided at the central position of the fixed base 1, and a pressurizing component 4 is threadedly connected in the threaded hole 8. The setting of the threaded hole 8 can fix the pressurizing component 4 to prevent the pressurizing component from shifting, and the pressing force of the pressurizing component can also be adjusted by rotating between the threads.

[0043] In this embodiment, the pressurizing assembly 4 includes a screw rod 41 and a rubber compression block 42. Correspondingly, the screw rod 41 passes through the threaded hole 8 in the center of the fixed base in sequence and is fixedly connected to the rubber compression block 42. When the pressurizing and fixing is performed, the rubber compression block 42 on the screw rod can be driven to pressurize by rotating the screw rod 41, and the compression force can be gradually reduced according to the conditions of different patients to improve the comfort of the patients; correspondingly, in this embodiment, the rubber compression block 42 has certain toughness and skin-friendliness; correspondingly, a cross notch 43 is also provided at the head end of the screw rod 41, and the setting of the cross notch can facilitate the operator to rotate it using a cross nut. In addition, anti-slip grooves (not shown in the figure) can also be provided around the head end of the screw rod 41, so as to increase the friction between the user's hand and the screw rod, thereby facilitating the user's rotation.

[0044] The method of using the utility model is as follows: when in use, the thumb and the index finger are sequentially sleeved on the finger restraint belt, and then the elastic fixing belt is placed along the base of the thumb parallel to the wrist, and then the elastic fixing belt is circularly wrapped along the thenar eminence to the back of the hand, and is adhered and fixed to the index finger restraint opening and the thumb restraint opening on the finger restraint belt, and the tightness is adjusted according to the actual situation of the patient. After the fixation is completed, the spiral rod is rotated and twisted to make the spiral rod drive the rubber compression block to apply pressure to the puncture site, and during the whole pressurization process, the spiral rod can be rotated and twisted according to the situation to make the rubber compression block compress the puncture point in the blood vessel to achieve an ideal compression and hemostasis effect.

[0045] It should be noted that: the device can be combined with the shape of the human hand according to the puncture site by matching the elastic fixing belt and the finger restraint belt (such as Figure 3 The hemostatic bandage is used as a guide and is used to fix the wound in an 8-shaped pattern. The bandage is then wrapped around the wrist for one week and then fixed tightly with a bristle bonding structure. The spiral rod is then rotated and twisted to apply pressure to the rubber compression block to compress the puncture point to achieve an ideal compression hemostasis effect. This can avoid the inaccurate compression of the wound position caused by traditional bandages for hemostasis, the discomfort caused by the large compression area of ​​the patient's hand, and the advantages of easy operation and real-time observation of the hemostasis situation. The device has a simple overall structure and is easy to operate, which reduces the risk of bleeding and increases the patient's comfort after surgery.

[0046] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and supplements without departing from the principle of the present invention. These improvements and supplements should also be regarded as the protection scope of the present invention.
