Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a radial artery hemostat. Background Technology

[0002] Radial artery compression hemostats are primarily used for hemostasis after radial artery puncture. During PCI, radial artery puncture has a lower risk of complications, faster recovery, and higher patient satisfaction compared to femoral artery puncture. However, improper hemostasis at the radial artery puncture site post-procedure can lead to impaired blood circulation in the hand, resulting in infection, inflammation, edema, and even ischemic necrosis of the hand.

[0003] Existing radial artery hemostats each have their shortcomings. Commercially available radial artery hemostats consist of a hemostat body, an air inlet tube, and an air inlet device. Different air inlet devices require different inflation and deflation devices to deflate the air bladder. Furthermore, existing hemostats often experience air leakage, which increases clinical risks and affects hemostasis.

[0004] A radial artery hemostat is already available. During hemostasis, the balloon of the radial artery hemostat needs to be aligned with the postoperative puncture site and then secured to the wrist with a wristband. The balloon's position is fixed, making it impossible to adjust it according to the patient's arm size or puncture site location. Furthermore, postoperatively, air is drawn from the balloon using a syringe to reduce pressure. With the syringe connected to the balloon, the high internal pressure can instantly push the syringe plunger, posing a risk of a sudden pressure drop if not carefully monitored.

[0005] Existing technology CN209826862U discloses a radial artery hemostat with a one-way air injection port. This radial artery hemostat uses a novel air injection device for inflation and deflation, which reduces some of the risk of leakage. However, the internal spring structure of the air injection device poses a risk of leakage due to the spring not fully returning during inflation and deflation. Furthermore, the gourd-shaped air bladder remains inflated for extended periods during use, and its connection to the air injection device is under constant stress, increasing the risk of leakage and detachment. Additionally, the air injection device requires a specific injector, resulting in poor convenience.

[0006] The prior art CN218739047U discloses a compression hemostat after radial artery puncture. This device uses a novel hemostatic mechanism, which can achieve partial and precise compression. However, it has multiple airbags that cannot be moved, requiring communication between the patient and the doctor to determine the location of the hemostasis point and the corresponding airbag to be inflated. This is inconvenient to use. Furthermore, the airbags can only be inflated and cannot be deflated, making adjustment difficult when too much gas is introduced or the airbag pressure is too high, resulting in cumbersome operation. Utility Model Content

[0007] The purpose of this invention is to provide a radial artery hemostat that is efficient and safe inflatable and deflateable, has an adjustable air bladder position, is simple to operate, and is convenient to use.

[0008] To achieve the above objectives, this utility model is implemented through the following technical solution: a radial artery hemostat, comprising an inflation structure, an air bladder, and a fixation device;

[0009] The fixing device includes Velcro, a main board, and a fixing strap; the Velcro is disposed on one side of the main board; the fixing strap is disposed on the main board, and the extending direction of the fixing strap is parallel to the extending direction of the main board; the airbag is fixed between the fixing strap and the main board;

[0010] The inflation structure includes a needleless connector, an extension tube, and a deflation valve; one end of the extension tube is connected to the needleless connector, and the other end is connected to the airbag; the deflation valve is located on the extension tube.

[0011] Furthermore: the needleless connector has a silicone sealing structure inside, and the needleless connector has an inflation / deflation port, which is a standard screw thread.

[0012] Furthermore, the fixing device also includes a rigid plate, which is disposed on the motherboard.

[0013] Furthermore, the fixing device includes at least one rigid sheet.

[0014] Furthermore, the connection between the hard chip and the motherboard is a heat-sealed connection.

[0016] Furthermore, the airbag is provided with marking dots, and the marking dots are polygonal in shape.

[0029] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] like Figure 1-6 As shown: This utility model provides a radial artery hemostat, including an inflation structure 1, an air bladder 2, and a fixing device 3;

[0031] The fixing device 3 includes a Velcro 11, a main board 12, and a fixing strap 13; the Velcro 11 is disposed on one side of the main board 12; as Figure 4 As shown, one end of the fixing strap 13 passes through the airbag 2 from the inside of the airbag 2, and the two ends of the fixing strap 13 are fixed to the main board 12 by heat sealing or adhesive bonding. The extension direction of the fixing strap 13 is parallel to the extension direction of the main board 12. The airbag 2 moves along the extension direction of the main board 12 through the fixing strap 13, and the airbag 2 is fixed between the fixing strap 13 and the main board 12.

[0032] The inflation structure 1 includes a needleless connector 21, an extension tube 22, and a deflation valve 23; one end of the extension tube 22 is connected to the needleless connector 21, and the other end is connected to the airbag 2; the deflation valve 23 is disposed on the extension tube 22.

[0033] According to a specific embodiment of the present invention, the needleless connector 21 is provided with a silicone sealing structure inside, and the needleless connector 21 is provided with an inflation / deflation interface, which is a standard screw thread.

[0034] According to a specific embodiment of the present invention, the fixing device 3 further includes a rigid sheet 14, which is disposed on the main board 12.

[0035] According to a specific embodiment of the present invention, the fixing device 3 includes at least one rigid sheet 14.

[0036] According to a specific embodiment of the present invention, the connection between the hard sheet 14 and the motherboard 12 is a heat-sealed connection.

[0037] According to a specific embodiment of the present invention, the airbag 2 is provided with a marking dot, and the marking dot is circular in shape.

[0038] According to a specific embodiment of the present invention, the airbag 2 is provided with marking dots, and the marking dots are polygonal in shape.

[0039] According to a specific embodiment of the present invention, the fixing strap 13 includes at least two fixing straps 13.

[0040] like Figure 4 As shown, according to a specific embodiment of this utility model, there are two fixing straps 13, which pass through both sides of the airbag 2. The position of the airbag 2 can be moved according to the patient's actual situation to achieve a precise compression effect.

[0041] According to a specific embodiment of this utility model, the main board 12 is made of a soft, transparent material that conforms to the patient's wrist. Three rigid sheets 14 are heat-sealed onto the main board 12. These rigid sheets 14 enhance the fixation effect while the main board 12 conforms to the wrist, achieving perfect fixation in a single operation and reducing the risk of repeated entanglement and detachment.

[0042] The working principle of this utility model is as follows:

[0043] In use, move the airbag 2 along the extension direction of the main board 12, align the marker on the airbag 2 with the area on the patient that needs compression to stop bleeding, wrap the main board 12 around the patient's wrist, and use Velcro 11 to secure the main board 12 tightly to the patient's wrist. After drawing a certain amount of air using a standard screw-in syringe, connect it to the needleless connector 21 and inflate the airbag 2. The airbag 2 will inflate and expand, applying pressure to the area on the patient that needs compression to stop bleeding until the medical staff determines that the compression is complete and the bleeding at the compression site has stopped. Then stop inflating the airbag and remove the standard screw-in syringe.

[0044] When it is necessary to reduce the pressure of airbag 2, open the vent valve 23 located on the extension tube 22. Gas will overflow through the hole after the vent valve 23 is pulled out. When the pressure of airbag 2 is appropriate, close the vent valve 23 on the extension tube 22.

[0045] Specifically, the present invention uses a needleless connector 21 as the inflation / deflation device, which can be directly inflated and deflated through a standard screw-in syringe. The use of the needleless connector 21 in conjunction with the screw-in syringe can effectively ensure airtightness.

[0046] It should be noted that this utility model uses a needleless connector as the inflation connector. Unlike existing radial artery hemostats on the market that use a one-way valve with a spring return mechanism, the needleless connector has a silicone sealing structure. The silicone's elasticity provides the seal, and when using a syringe to inflate or deflate, the excellent resilience of the silicone provides better stability than a spring, effectively reducing the risk of air leakage caused by insufficient spring return.

[0047] It should be noted that this invention provides a safer pressure relief method. When it is necessary to reduce the pressure of the airbag, the vent valve located on the extension tube can be directly pulled out. The gas overflows through the hole after the vent valve is pulled out, achieving a gradual pressure reduction effect. Most airbag hemostats on the market use a syringe to draw air from the airbag to reduce pressure. The pressure relief process is complicated, and when drawing air, the pressure in the airbag acts on the syringe plunger, which can easily cause the plunger to slip, resulting in a sudden gas overflow from the airbag and a sudden drop in pressure, leading to hemostasis failure. This invention eliminates the need for multiple subsequent syringe depressurization operations, reducing the risk of sudden pressure drops caused by human error and reducing the workload of medical staff.

[0048] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent transformations or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
