Description

Technical Field

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

[0002] Normally, interventional surgery, arterial blood gas collection, invasive blood pressure monitoring, etc. are mostly performed through radial or ulnar artery puncture. Compared with femoral artery and radial artery puncture, distal radial artery puncture has more advantages and becomes the preferred arterial puncture point in actual clinical operations.

[0003] 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.

[0004] In addition, the radial artery is located between the thumb and index finger above the human wrist, and it is more difficult to fix and compress it than the proximal radial artery. Generally, after surgery, overlapping gauze is required to compress the puncture point to stop bleeding from the postoperative wound. Currently, there is no dedicated instrument on the market. Usually, after the operation is completed, a bandage or a hemostat is used to achieve hemostasis and closure of the arterial puncture point.

[0005] When using a bandage to stop bleeding, the doctor or medical professional first applies pressure with the fingertips at the arterial puncture point, and then compresses the puncture point using an artificial gauze bandage. The technique depends entirely on the operator's personal experience. There are different ways to tie a gauze bandage, which is time-consuming and labor-intensive, and the effects of compression hemostasis vary greatly.

[0006] The traditional bandage wrapping method currently used by doctors is not convenient for operation and postoperative observation. At the same time, due to the need for compression cycles, continuous high-pressure compression can easily cause patient discomfort and even injuries such as pressure blisters.

[0007] Therefore, in summary, there is an urgent need for a compression hemostat for the radial artery puncture point that can fix and adjust the distal thumb and index finger, and the compression force can be adjusted at any time according to the needs of use and the patient's feelings, is simple to operate, and greatly improves the patient's comfort and hemostasis efficiency.

[0038] Please see attached Figure 1-4 As shown, attached Figure 1 Attached is a schematic diagram of the structure of the hemostatic device for compressing the radial artery puncture point in the embodiment of the utility model. Figure 2 Schematic diagram of the structure of the compression device base and the finger restraint belt in the embodiment of the utility model. Figure 3 Attached is a schematic diagram of the structure of the inflatable branch pipe in the embodiment of the utility model. Figure 4 This is an implementation diagram of a compression hemostat for radial artery puncture point in an embodiment of the utility model.

[0039] This device mainly solves the problem of fixing and adjusting the distal thumb and index finger, and the compression force can be adjusted at any time according to the needs of use and the patient's feelings, reducing the risk of bleeding, while increasing the patient's postoperative comfort and reducing compression complications. Based on this, a compression hemostat for radial artery puncture point is specially designed.

[0040] like Figure 1 , Figure 2 As shown, the device includes a compression base 1, two elastic fixing straps 2, a finger restraint strap 3, a compression airbag 4, an inflation branch pipe 5, an inflation device 6 and a pressure gauge 7;

[0041] Among them, two elastic fixing straps 2 and finger restraint straps 3 are respectively connected to the compressor base 1; correspondingly, the two elastic fixing straps 2 and the finger restraint straps 3 are respectively arranged in different directions; in this embodiment, the compressor base 1 is selected to be triangular, forked or polygonal, so as to facilitate stable fixation. At the same time, the compressor base 1 is made of transparent material as a whole, which can be convenient for subsequent observation, and is quick and convenient.

[0042] Correspondingly, Velcro 8 is provided on both the front and back surfaces of the elastic fixing belt 2, and the length of the elastic fixing belt 2 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.

[0043] like Figure 3 As shown, correspondingly, the finger restraint belt 3 is a U-shaped structure as a whole, and an index finger restraint opening 31 and a thumb restraint opening 32 for receiving the index finger and the thumb are respectively provided on the finger restraint belt 3, wherein the shapes of the index finger restraint opening 31 and the thumb restraint opening 32 are correspondingly fitted to the index finger and the thumb; 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.

[0044] During use, the thumb restraint opening 32 is sleeved on the patient's thumb, and the index finger restraint opening 31 is sleeved on the patient's index finger. The thumb restraint opening 32 and the index finger restraint opening 31 are interference fit with the corresponding fingers. In order to further increase stability, a rubber sleeve that can be fitted can be provided on the inner side of the thumb restraint opening 32 and the index finger restraint opening 31 to increase the friction between the thumb restraint opening and the index finger restraint opening and the fingers, thereby making the thumb restraint opening 32 and the index finger restraint opening 31 reliably fixed on the corresponding fingers; this structure is fixed on the corresponding fingers by the thumb restraint opening 31 and the index finger restraint opening 31. The thumb and index finger are placed on the corresponding fingers, which can not only form a reliable support for the compression hemostat and position the compression hemostat against the base of the thumb, but also the thumb restraint opening 31 and the index finger restraint opening 32 can fix the thumb and index finger, keep the relative posture of the thumb and index finger fixed, and avoid wound tearing caused by the relative movement of the thumb and index finger by stabilizing the posture of the thumb and index finger. At the same time, the reliable positioning of the puncture wound can be ensured, so that the wound will not be displaced due to the relative movement of the index finger or thumb, which is conducive to the reliable hemostatic pressing of the hemostatic pressing device and can improve the hemostatic effect.

[0045] In addition, after the finger is inserted into the finger restraint band 3, the finger restraint band 3 and the internal compression airbag 4 are fixed together, so that the skin puncture point can be effectively compressed, and the pressure applied to the skin tissue is uniform, and no pressure sores are formed, which further cooperates with the adhesion and tightening effect between the finger restraint band 3 and the elastic fixing band 2; at the same time, under the action of the compression airbag 4, the finger restraint band structure can be tightened, and the hemostatic effect is better. The device is stable and convenient to wear, and its adhesive method saves time and effort.

[0046] In this embodiment, the finger restraint 3 is made of an adhesive material (containing a bristle adhesive structure) and can be 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 3, the elastic fixing belt 2 and the mother-and-child Velcro 8 are all made of soft and skin-friendly materials, so that the patient's comfort when using them can be improved when they are fixed with pressure.

[0047] Correspondingly, compression airbags 4 are provided on the two elastic fixing straps 2 and the finger restraint straps 3; wherein, an inflation branch pipe 5 is also provided in the compressor base 1; correspondingly, the inflation branch pipe 5 and the compression airbag 4 are interconnected; correspondingly, a pressure gauge 7 is also provided on the compressor base 1, wherein the inflation device 6 forms an inflation circuit by connecting the inflation branch pipe 5, the pressure gauge 7 and the compression airbag 4.

[0048] In addition, the inflation device 6 includes an inflation guide tube 61, an air bag 62 and an inflation valve 63; wherein the inflation guide tube 61 is interconnected with the inflation branch tube 5. When in use, the air bag 62 can be squeezed and inflated; the inflation needle can also be inserted into the inflation valve 63 for inflation, or the inflation valve 63 can be directly connected to an external air pump, and the pressure on the wound can be adjusted by the air pump for real-time inflation; with the continuous input of the inflation device 6, the inflation branch tube 5 connected to the inflation device 6 will gradually inflate the connected pressure gauge 7 and the compression air bag 4, thereby achieving the purpose of pressurizing the wound and achieving the purpose of compression and hemostasis; the setting of the pressure gauge 7 can make the compression more intuitive, and the compression strength can be adjusted at any time according to the use needs and the patient's feelings, which is simple to operate and improves the comfort of the patient.

[0049] See again Figure 2As shown, in this embodiment, the inflation branch pipe 5 is in a herringbone structure, and the three tube holes are interconnected, and are respectively connected to the compression airbags 4 in the two elastic fixing belts 2 and the finger restraint belt 3; wherein, a side pipe 51 is also arranged above the inflation branch pipe 5; correspondingly, the side pipe 51 is interconnected with the pressure gauge 7. Correspondingly, the gas input through the inflation device 6 will be diverted through the inflation guide pipe 61, part of it will enter the compression airbag 4 in the finger restraint belt, part of it will also enter the compression airbag 4 in the two elastic fixing belts, and the other part will enter the pressure gauge 7, and the pressure value will be monitored by the pressure gauge 7, which is safer and more stable.

[0050] In addition, the two elastic fixing straps 2 and the finger restraint straps 3 in this embodiment are both made of high-elasticity materials, thereby better improving the comfort of use for patients and facilitating fixation and disassembly by patients.

[0051] The method of using the utility model is as follows: when in use, the thumb and the index finger are sleeved on the finger restraint belt in sequence, and then the elastic fixing belt is placed along the base of the thumb and the wrist in parallel, and then the elastic fixing belt is wrapped around the thenar eminence to the back of the hand in a circular manner, 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 inflation device is used to inflate the inflation branch tube in the compressor base, so that air flows into different positions through the inflation branch tube, thereby realizing the application of pressure to the puncture site, and in the whole pressurization process, the pressure gauge, the inflation device and the pressurization airbag can cooperate with each other according to the situation, so as to realize the compression of the precise compression puncture point in the blood vessel, so as to achieve the ideal compression hemostasis effect.

[0052] 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 4 As shown in the figure, it is fixed in an 8-shape, then wrapped around the wrist for a week and fixed tightly by a bristle bonding structure, and then the compression airbag is pressurized by an inflation device to achieve an ideal compression hemostasis effect, thereby avoiding the inaccurate compression of the wound position caused by traditional bandages for hemostasis, and the discomfort of the patient caused by a large compression area of ​​the patient's hand, as well as the advantages of simple operation and easy real-time observation of the hemostasis situation; at the same time, the compression force can be adjusted at any time according to the needs of use and the patient's feelings, and the operation is simple, which greatly improves the patient's comfort and hemostasis efficiency; in addition, the overall structure of the device is simple, the operation is convenient, the risk of bleeding is reduced, and the patient's comfort after surgery is increased.

[0053] 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.
