Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a device for stopping bleeding at a venous puncture site. Background Technology

[0002] In clinical medicine, nurses perform intravenous punctures. After needle removal, depending on the puncture site, the nurse will instruct the patient to apply pressure to the wound with a cotton swab or use a dressing to stop the bleeding. To address the issue of arm pain caused by patients manually and continuously applying pressure with a cotton swab, existing devices use a fixing component to secure the pressure-closing component to the puncture site. After the medical staff withdraws the needle, the pressure-closing component moves downwards to apply pressure to the wound.

[0003] However, in actual operation, on the one hand, it is necessary to first remove the needle from the patient's vein and then drive the compression hemostasis component to stop the bleeding in the patient's vein. This process takes a long time, during which blood may leak from the puncture point, causing blood to flow out. On the other hand, due to the large size of the device, it may shake with the patient's hand, causing the hemostasis compression plate to shift and causing subcutaneous bruising. In addition, because there is a certain distance between the compression hemostasis device and the patient's puncture point, there may be inaccurate judgment of the puncture point, resulting in incomplete pressure on the puncture point, causing blood to flow out and poor hemostasis. Utility Model Content

[0004] To address the aforementioned problems, the present invention aims to provide a hemostatic device for intravenous puncture sites that can apply pressure to the wound promptly when the needle is withdrawn from the puncture site, while minimizing the risk of subcutaneous bruising caused by displacement of the pressure plate between the device and the puncture site due to device shaking.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A hemostatic device for intravenous puncture sites includes a fixing patch assembly and a hemostatic component disposed on the lower surface of the fixing patch assembly for hemostasis at the puncture site; the fixing patch assembly includes a first fixing patch and a second fixing patch disposed on the rear side of the first fixing patch and connected by an easy-tear line; the hemostatic component includes a positioning sub-component disposed on the lower surface of the first fixing patch for positioning the puncture needle and a compression sub-component disposed on the lower surface of the second fixing patch for applying pressure to the puncture site for hemostasis; the positioning sub-component includes a component embedded in the first fixing patch. The fixed patch includes a needle handle limiting block in the middle and an arc-shaped support member vertically fixed behind the needle handle limiting block and covering the needle tip of the puncture needle; the lower surface of the needle handle limiting block has a placement groove adapted to the needle handle; the compression sub-assembly includes a pair of limiting rings symmetrically fixed on the lower surface of the second fixed patch and located on both sides of the arc-shaped support member, an arc-shaped compression elastic sheet movably inserted between the two limiting rings, and a hemostatic sheet abutting below the middle of the lower surface of the arc-shaped compression elastic sheet; the arc-shaped support member is located directly below the hemostatic sheet.

[0007] More preferably, the needle handle limiting block has a clamping groove for holding the first fixing sticker in the middle of its surrounding sides.

[0008] More preferably, the lower surface of the first fixing sticker is detachably provided with a first protective paper, and the lower surface of the second fixing sticker is detachably provided with a second protective paper.

[0009] This utility model has the following beneficial effects:

[0010] This invention, when the arc-shaped support is withdrawn from under the hemostatic patch, causes the arc-shaped compression elastic plate to lose the pressure exerted by the arc-shaped support on the hemostatic patch. Under the action of elasticity, the plate recovers its deformation and moves towards the patient's skin side, applying pressure to the puncture site to achieve hemostasis. During this process, as the arc-shaped support is withdrawn from under the hemostatic patch, the patch itself compresses the puncture site under the action of the arc-shaped compression elastic plate, eliminating the need for manual downward pressure to achieve hemostasis and reducing the need for manual removal of the needle from the puncture site. After the procedure, the device manually applies pressure. On the other hand, the pressure of the arc-shaped elastic plate compresses the hemostatic pad against the patient's puncture point to achieve hemostasis. Under the action of elasticity, the hemostatic compression plate will not move at the puncture point, thus minimizing the risk of subcutaneous bruising caused by displacement of the hemostatic compression plate. In addition, the hemostatic compression plate has a large area, and the device is calibrated by the needle handle limiting block, which can completely cover the puncture point. This avoids situations where inaccurate judgment of the puncture point leads to incomplete pressure on the puncture point, causing blood leakage and poor hemostasis. Attached Figure Description

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] A hemostasis device for intravenous puncture sites includes a fixing patch assembly 1 and a hemostatic component 2 disposed on the lower surface of the fixing patch assembly 1 for hemostasis at the puncture site; the fixing patch assembly 1 includes a first fixing patch 11 and a second fixing patch 12 disposed on the rear side of the first fixing patch 11 and connected by an easy-tear line 13; the hemostatic component 2 includes a positioning sub-component 21 disposed on the lower surface of the first fixing patch 11 for positioning the puncture needle and a compression sub-component 22 disposed on the lower surface of the second fixing patch 12 for applying pressure to the puncture site for hemostasis; the positioning sub-component 21 includes a needle handle limiting device embedded in the middle of the first fixing patch 11. The block 211 and the arc-shaped support 212 vertically fixed behind the needle handle limiting block 211 and covering the needle tip of the puncture needle; the lower surface of the needle handle limiting block 211 is provided with a placement groove 2112 adapted to the needle handle; the compression sub-assembly 22 includes a pair of limiting band rings 221 symmetrically fixed on the lower surface of the second fixing patch 12 and located on both sides of the arc-shaped support 212, an arc-shaped compression elastic sheet 222 movably passing between the two limiting band rings 221, and a hemostatic sheet 223 abutting below the middle of the lower surface of the arc-shaped compression elastic sheet 222; the arc-shaped support 212 is located directly below the hemostatic sheet 223.

[0023] The needle handle of the puncture needle is placed inside the needle handle limiting block 211. When it is necessary to remove the puncture needle from the patient's vein, the needle handle is pulled outward along with the first fixing patch 11, the needle handle limiting block 211, and the arc-shaped support 212 until the needle tip is completely removed from the second fixing patch 12. As the arc-shaped support 212 is pulled away from under the hemostatic patch 223, the arc-shaped compression elastic patch 222 loses the pressure exerted by the arc-shaped support 212 on the arc-shaped compression elastic patch 222 through the hemostatic patch 223. Under the action of elasticity, it recovers its deformation and moves the hemostatic patch 223 towards the patient's skin side, applying pressure to the puncture point to achieve hemostasis. During this process, when the arc-shaped support 212 is pulled away from under the hemostatic patch 223, the hemostatic patch 223 will compress and stop the bleeding at the puncture point of the patient's wound under the action of the arc-shaped compression elastic patch 222, without the need for manual intervention. To achieve hemostasis at the patient's puncture site by pressing down the device, the time required for manual pressing of the device after the puncture needle is withdrawn from the puncture site is reduced. On the other hand, the pressure of the arc-shaped elastic plate 222 presses the hemostatic plate 223 against the patient's puncture site to achieve hemostasis. Under the action of elasticity, the hemostatic pressure plate 223 will not move at the puncture site, thereby minimizing the possibility of subcutaneous bruising caused by displacement of the hemostatic pressure plate 223. In addition, the device is calibrated for the puncture area by the needle handle limiting block 211, and the hemostatic pressure plate 223 has a large area, which can completely cover the puncture site, thereby avoiding the situation where the puncture site is not fully pressed due to inaccurate judgment during hemostasis, resulting in blood leakage and poor hemostasis effect. It is also convenient for the patient to remove the first fixing patch 11 and the positioning sub-assembly 21 from the second fixing patch 12 and the pressure sub-assembly 22.

[0024] As a possible implementation of this solution, preferably, the needle handle limiting block 211 has a clamping groove 2111 for holding the first fixing sticker 11 around the center of its four sides; the clamping groove 2111 can further enhance the firmness of the fixation between the needle handle limiting block 211 and the first fixing sticker 11, so as to minimize the risk of the needle handle limiting block 211 falling off the first fixing sticker 11.

[0025] As a possible implementation of this solution, preferably, the lower surface of the first fixing sticker 11 is detachably provided with a first protective paper 14, and the lower surface of the second fixing sticker 12 is detachably provided with a second protective paper 15; the setting of the first protective paper 14 and the second protective paper 15 can maintain the adhesiveness of the fixing sticker group 1 when the device is not in use.

[0026] The working principle of this device is as follows:

[0027] In use, first install the arc-shaped support 212 onto the front end of the needle handle limiting block 211. After the medical staff inserts the needle tip into the vein through the needle handle, peel off the first protective paper 14 and the second protective paper 15 from the first fixing sticker 11 and the second fixing sticker 12. Then, align the placement groove 2112 of the needle handle limiting block 211 with the needle handle and attach the device to the puncture site. When it is necessary to remove the needle, peel off the first fixing sticker 14 through the easy-tear line 13. 1. Separate from the second fixing patch 12 on both sides, and then pull out the puncture needle, needle handle limiting block 211, arc-shaped support 212 and first fixing patch 11 along the extension direction of the needle tip. When the arc-shaped support 212 is pulled out from below the hemostatic patch 223, the hemostatic patch 223 is pressed down under the elastic force of the arc-shaped compression elastic patch 222 to achieve compression hemostasis at the puncture point. In this device, the front end of the arc-shaped support 212 is at the same level as the puncture needle tip.

Any equivalent structural transformations made based on the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
