Description

Technical Field

[0001] This utility model relates to an arteriovenous puncture point pressure hemostat, which belongs to an auxiliary hemostasis device. Background Technology

[0002] Currently, after arterial or venous injections, there is often leakage at the injection site, which is usually controlled by applying pressure after needle removal. Failure to apply pressure to the injection site promptly can lead to further bleeding, posing health and safety risks to the patient. Significant bleeding can hinder the patient's recovery. Furthermore, the leaked blood poses a risk of contamination.

[0003] Applying pressure to stop bleeding is usually done by nursing staff or the patient themselves.

[0004] For people with normal hands, applying pressure to the injection site to stop bleeding is not a problem. However, for patients without caregivers or with limited mobility, applying pressure to the injection site to stop bleeding is quite inconvenient.

[0005] Currently, there are various hemostatic compression devices, such as a compression hemostatic device for intravenous infusion (application number 201811020300.0), which uses a rotating mechanism to press the needle site. This type of structure is relatively large, and its weight is increased due to the complexity of the positioning and rotating mechanisms. Utility Model Content

[0006] This invention provides a pressure hemostat for arterial and venous puncture points, which solves the problem of pressure on the needle sites for arterial and venous blood drawing and infusion. It is lightweight and has a timing function.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] This utility model of an arteriovenous puncture point compression hemostat includes a first compression plate, a second compression plate, a two-degree-of-freedom blood pressure plate, and an elastic element;

[0009] The front end of the first pressing plate is provided with a two-degree-of-freedom hemostatic plate, and the first pressing plate and the second pressing plate are provided with elastic elements at their rear ends. The elastic elements drive the front ends of the two-degree-of-freedom hemostatic plate and the second pressing plate to move closer together. The two-degree-of-freedom hemostatic plate covers the arteriovenous puncture point, and the second pressing plate supports the human limb below the arteriovenous puncture point.

[0010] The two-degree-of-freedom blood pressure plate is connected to the front end of the first pressure plate via a universal joint.

[0011] According to the arteriovenous puncture point pressing hemostat, the universal joint is a series of transverse and longitudinal hinges. The two-degree-of-freedom hemostat plate is connected to the front end of the first pressing plate through the transverse and longitudinal hinges. The transverse hinge is perpendicular to the length direction of the first pressing plate, and the longitudinal hinge is perpendicular to the transverse hinge. An elastic sheet is also provided between the first pressing plate and the two-degree-of-freedom hemostat plate. The elastic sheet prevents the two-degree-of-freedom hemostat plate from flipping up at the transverse hinge.

[0012] According to the arteriovenous puncture point pressing hemostat, the universal joint is a ball-head universal joint, and there is an adjustable length bolt structure between the universal joint and the first pressing plate. The universal joint is fixed at the bottom of the bolt. The universal joint is located in the middle of the upper side of the two-degree-of-freedom hemostat. The bolt passes through the fixing nut, and the fixing nut is located at the front end of the first pressing plate.

[0013] The arteriovenous puncture point compression hemostat also includes a timer, which is fixed to the first or second compression plate. The timer has a built-in buzzer that sounds an alarm when the timer reaches its limit.

[0014] According to the arteriovenous puncture point pressing hemostat, the front end of the first pressing plate is provided with a pair of hinged hole plates, the horizontally hinged pin is passed through the hole of the hinged hole plate, the front end of the horizontally hinged plate is provided with a longitudinal hinge shaft, the rear end of the two-degree-of-freedom hemostat plate is provided with a hinge shaft hole, and the longitudinal hinge shaft is inserted into the hinge shaft hole.

[0015] According to the arteriovenous puncture point pressing hemostat, the lower surface of the two-degree-of-freedom hemostatic plate is provided with a hemostatic compression layer, which is a skin-friendly coating wrapped with elastic cotton. When the hemostatic compression layer is attached to the arteriovenous puncture point, sterile cotton is applied.

[0016] According to the arteriovenous puncture point compression hemostat, the inner surface of the second compression plate is covered with a 5-10 mm thick sponge, and the middle of the second compression plate has an indentation perpendicular to its length.

[0017] According to the arteriovenous puncture point compression hemostat, the elastic element is a torsion spring. The first pressing plate and the second pressing plate protrude towards the middle and are connected by a pin. The torsion spring is sleeved on the pin. The two ends of the torsion spring extend and abut against the inner sides of the first pressing plate and the second pressing plate respectively. The torsion spring pushes the rear sides of the first pressing plate and the second pressing plate to separate and the front sides to move closer.

[0018] According to the arteriovenous puncture point compression hemostat, the front ends of the first compression plate and the second compression plate are arranged in a clamp shape.

[0019] The advantages of this utility model are:

[0020] It can achieve the purpose of stopping bleeding by pressing the injection site, eliminating the need for the patient or caregiver to apply pressure to stop the bleeding;

[0021] The front end structure is adjustable in direction, making it suitable for applying pressure to stop bleeding at different locations of the patient's arterial or venous needle sites. It can be applied to the hands, arms, legs, or feet at different heights, providing good pressure relief. The direction of the pressure point can be adjusted according to the pressure location, increasing its usability and convenience.

[0022] It is convenient for medical staff to operate, saves time and effort, and provides good comfort when pressing on the patient's puncture site. Attached Figure Description

[0031] The specific structure of this utility model will be further described below:

[0032] This utility model of arteriovenous puncture point pressure hemostat includes a first pressure plate 1, a second pressure plate 2, a two-degree-of-freedom blood pressure plate 3, and an elastic element 4.

[0033] The first pressure plate 1, the second pressure plate 2, and the two-degree-of-freedom blood pressure plate 3 are made of lightweight aluminum alloy or hard, thin plastic.

[0034] The front ends of the first pressing plate 1 and the second pressing plate 2 are arranged in a clamp shape. The first pressing plate 1 and the second pressing plate 2 are provided with elastic elements 4 at their rear ends. The elastic elements 4 drive the two-degree-of-freedom hemostatic plate at the front end of the first pressing plate 1 and the front end of the second pressing plate 2 to move closer together. The two-degree-of-freedom hemostatic plate covers the arteriovenous puncture point, and the second pressing plate 2 supports the human limb below the arteriovenous puncture point.

[0035] The two-degree-of-freedom blood pressure plate (3) is connected to the front end of the first pressure plate (1) via a universal joint.

[0036] Specific Implementation Example 1

[0037] The universal joint is a ball joint. An adjustable bolt structure is provided between the universal joint and the first pressing plate (1). The universal joint is fixed at the bottom of the bolt. The universal joint is located in the middle of the upper side of the two-degree-of-freedom hemostatic plate. The bolt passes through the fixing nut. The fixing nut is located at the front end of the first pressing plate (1).

[0038] The two-degree-of-freedom hemostatic plate is connected to the front end of the first pressing plate 1 through a transverse hinge 6 and a longitudinal hinge 5. The transverse hinge 6 is perpendicular to the length direction of the first pressing plate 1, and the longitudinal hinge 5 is perpendicular to the transverse hinge 6. An elastic sheet 7 is also provided between the first pressing plate 1 and the two-degree-of-freedom hemostatic plate. The elastic sheet 7 prevents the two-degree-of-freedom hemostatic plate from flipping up at the transverse hinge 6.

[0039] A timer 8 is also provided to control the pressing time. The timer 8 is fixed on the first pressing plate 1 or the second pressing plate 2. The timer 8 has a built-in buzzer, which sounds an alarm when the timer reaches the set time. Specifically, a fixing hole is provided at the rear end of the first or second pressing plate, and the timer is hung in the fixing hole. The timer in this device is purchased from a third party and is directly hung in the fixing hole using a metal ring.

[0040] The front end of the first pressing plate 1 is provided with a pair of hinge hole plates. The pin of the transverse hinge 6 passes through the hole in the hinge hole plate. The front end of the transverse hinge 6 is provided with a longitudinal hinge shaft. The rear end of the two-degree-of-freedom hemostatic plate is provided with a hinge shaft hole, into which the longitudinal hinge shaft is inserted. Through the setting of the transverse and longitudinal hinge shafts, the two-degree-of-freedom hemostatic plate can be adjusted in the left-right and pitch angles to adapt to the hemostatic pressing position of various patients.

[0041] The lower surface of the two-degree-of-freedom hemostatic plate of this device is provided with a hemostatic compression layer 9. The hemostatic compression layer 9 is a skin-friendly coating wrapped with elastic cotton. When the hemostatic compression layer 9 is attached to the arterial and venous puncture site, sterile cotton 10 is applied. The skin-friendly coating is pressed against the skin to compress the medical sterile cotton, and the sterile cotton covers the arterial and venous puncture needle site.

[0042] The inner surface of the second pressing plate 2 is covered with a 5-10 mm thick sponge, and the middle of the second pressing plate 2 has an indentation perpendicular to its length to match the position of the arterial and venous puncture needle in the human body.

[0043] To adjust the pitch angle of the two-degree-of-freedom hemostat, an elastic plate is fixed at its rear end to the first pressing plate 1, and its front end is inserted into a hole on the upper surface of the two-degree-of-freedom hemostat. The hole is aligned with the length of the two-degree-of-freedom hemostat, avoiding the presence of a sliding groove perpendicular to the hole. A sliding element is embedded in the sliding groove, and the lower side of the sliding element has concave and convex teeth. The corresponding upper surface of the elastic plate has concave and convex grooves. When the sliding element is slid, the concave and convex teeth engage with the concave and convex grooves of the elastic plate, thus fixing the front end of the elastic plate. The concave and convex grooves on the elastic plate are long enough to match the length of the elastic plate inserted into the hole, thereby adjusting the angle between the back of the two-degree-of-freedom hemostat and the first pressing plate, controlling the pitch angle of the two-degree-of-freedom hemostat. The elastic plate is preferably made of aluminum alloy, which has compressive strength and can recover after slight deformation.

[0044] As part of the implementation, the elastic element 4 of this device is a torsion spring. The first pressing plate 1 and the second pressing plate 2 protrude towards the center and are connected by a pin. The torsion spring is sleeved on the pin, and its two ends extend to abut against the inner sides of the first pressing plate 1 and the second pressing plate 2, respectively. The torsion spring pushes the rear sides of the first pressing plate 1 and the second pressing plate 2 towards separation and the front sides towards convergence. The torsion spring can also be replaced with a conventional compression spring, with its two ends abutting against the inner rear ends of the first pressing plate 1 and the second pressing plate 2, and a limiting structure is provided to prevent the spring from falling off, achieving the same effect.

[0045] The surface of this device is coated with a skin-friendly material to avoid causing discomfort to the human skin.

[0046] When using this device, by pressing the first and second pressure plates, the front ends of the second pressure plate 2 and the first pressure plate are opened. The two-degree-of-freedom blood pressure plate at the front end of the first pressure plate presses against the arterial and venous puncture needle site. The second pressure plate supports the lower limb of the person at the needle site. Sterile cotton is first placed under the lower part of the two-degree-of-freedom blood pressure plate. Then, the rear ends of the first and second pressure plates are released in alignment with the needle site. The second pressure plate 2 and the first pressure plate are clamp-shaped and press the needle site.

[0047] Taking the intravenous infusion needle site on the back of the hand as an example, the needle site may be located on the left, middle, or right side, and the thickness of the palm at the needle site varies. By adjusting the angle and rotation direction of the two-degree-of-freedom blood pressure plate, the condition of the needle site can be matched, allowing for the best pressure application to the needle site. For example, if one side of the needle site is higher than the other, the two-degree-of-freedom blood pressure plate can be rotated around the longitudinal hinge axis at four centers to adapt to the needle site position of different palm thicknesses.

[0048] If the needle is at the rear end, and the arm itself is an irregular cylinder, the lower part of the arm is supported by the second pressure plate. The pitch angle of the two-degree-of-freedom blood pressure plate is adjusted to match the arm thickness of different patients. When the patient's arm is thicker, the two-degree-of-freedom blood pressure plate is placed on top, and then the position of the elastic plate is fixed so that the opening angle of the first and second pressure plates is larger to adapt to the patient's thicker arm.

[0049] If the patient is a child with a thinner arm, the two-degree-of-freedom blood pressure relief plate can be adjusted to fit the child's arm with a smaller opening angle between the first and second compression plates.

[0050] It is convenient for medical staff to operate, saving time and effort, and provides good comfort when pressing on the patient's puncture site.
