Description

Technical Field

[0001] The utility model belongs to the technical field of hemostats, and in particular relates to a pressure-controllable hemostat for arterial puncture. Background Art

[0002] Chinese utility model patent CN2023212951746 discloses a compression hemostatic wristband for radial artery puncture point, which solves the problem that the hemostatic wristband is prone to excessive or insufficient deflation when the overall airbag is decompressed. In fact, it is also to find a better pressure for compression hemostasis. However, the above-mentioned compression hemostatic wristband has the following problems in the process of adjusting the pressure (inflation and deflation): 1. It is difficult to control the pressure of the airbag compression hemostasis; 2. The airbag and skin compression contact area is large, resulting in pressure damage to the skin around the puncture site. Summary of the invention

[0003] The utility model aims to provide a controllable pressure hemostat for arterial puncture, in which the pressure degree is controlled by rotating the hemostatic pressure column, and the effect is more intuitive. At the same time, the pressure point is directly opposite to the puncture site, which can achieve accurate pressure hemostasis and avoid local pressure damage to the puncture site.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A pressure-controlled hemostat for arterial puncture, comprising an elastic band, a positioning display board, a hemostatic compression column, and a protective pad that adheres closely to the skin at the puncture site;

[0006] There are two elastic bands, and the two elastic bands are rotatably connected to the two ends of the positioning display board respectively;

[0007] The positioning display plate is provided with a thread groove, the side end of the hemostatic compression column is provided with a thread adapted to the thread groove, and the hemostatic compression column is screwed in the thread groove;

[0008] The protective gasket is rotatably connected to the hemostatic compression column.

[0009] There are two elastic bands, similar to watch straps, which are used to wrap around the patient's arm for fixation. The positioning display board is made of a slightly hard plastic material. A silicone layer can be pasted on the side that fits the skin to avoid pressure injuries caused by long-term contact with the skin. The compression hemostatic column is made of hard plastic. The end close to the skin can contact and press the bleeding puncture site, thereby achieving a hemostatic effect. In order to increase the comfort of patients during use, a protective gasket is connected to the lower end of the hemostatic compression column to prevent the skin around the puncture site from being damaged by pressure. The protective gasket is rotatably connected to the hemostatic compression column. When in use, the protective gasket is in close contact with the skin. When the pressure needs to be increased, the protective gasket can be pressed by hand and the hemostatic compression column can be rotated to adjust the pressure, and the protective gasket will not rotate with it.

[0010] 1. Elastic bandage, 2. Positioning display board, 3. Positioning ring, 4. Hemostatic compression column, 5. Rotating end, 6. Scale mark, 7. Protective gasket, 8. Insert column, 9. Insert ring, 10. Velcro hook surface, 11. Rotating axis.

[0011] Preferably, a cutting surface is provided at the side end of the hemostatic compression column, and scale marks are provided on the cutting surface.

[0012] The purpose of the scale markings is to facilitate the staff to judge the degree of pressure applied. For example, in the initial stage, turn the hemostatic compression column to the maximum scale and adjust it every half an hour. After half an hour, turn the hemostatic compression column to a smaller scale to avoid excessive pressure for a long time and cause local skin injury. Compared with airbag pressure control, the method of this application is more stable and simpler to operate, and does not involve inflation and deflation operations.

[0013] Preferably, the interval between the scale marks is 5 mm.

[0014] The interval between scale marks can be produced in different specifications according to actual needs, the most common one is 5mm.

[0015] Preferably, a positioning ring is provided on the positioning display plate to prevent the hemostatic compression column from rotating and bending sideways, and the hemostatic compression column is inserted into the hollow interior of the positioning ring.

[0016] The positioning ring is used to prevent the hemostatic compression column from tilting sideways, because the skin of the arm is a curved surface. Without the lateral support of the positioning ring, the hemostatic compression column is prone to tilting sideways.

[0017] Preferably, a notch through which the scale mark is exposed is provided on the positioning ring.

[0018] Through the notch set on the positioning ring, the scale numbers can be clearly observed, making it convenient for the staff to make adjustments.

[0019] Preferably, an insertion post is provided at one end of the hemostatic compression column close to the skin, and correspondingly, an insertion ring adapted to the insertion post is provided on the protective gasket, and the hemostatic compression column and the protective gasket are buckled and fixed.

[0020] The protective gasket is buckled on the end of the hemostatic compression column. When in use, the protective gasket can be buckled in and fixed. The protective gasket and the end of the hemostatic compression column are rotatably connected. The protective gasket still fits the skin when the hemostatic compression column rotates, and will not affect the puncture site. And the protective gasket is replaceable because it is in direct contact with the patient, and the compression hemostat can be used again after sterilization, which can greatly reduce medical costs.

[0021] Preferably, the upper end of the hemostatic compression column is provided with a rotating end for convenient force application.

[0022] The rotating end is made into a cylindrical shape, which is convenient for medical staff to apply force when rotating.

[0023] Preferably, both ends of the positioning display board are provided with a rotation groove, a rotation shaft is fixed in the rotation groove, and the end of the elastic band is sleeved with the rotation shaft.

[0024] Preferably, one end of one of the elastic bands facing away from the positioning display board is provided with a Velcro hook surface, and the other end of the elastic band facing away from the positioning display board is provided with a Velcro fleece surface.

[0025] When in use, the two ends of the elastic strap are wrapped around the arm, and the two free ends are fixed by the Velcro hook surface and the Velcro fleece surface. The advantage of the Velcro hook surface and the Velcro fleece surface design is that it can be adjusted according to the arm circumference of different patients, making it more adaptable.

[0026] Preferably, the material of the protective gasket is silicone.

[0027] Silicone is soft and non-toxic, and will not cause allergies after long-term contact with the patient's skin.

[0028] Compared with the prior art, the beneficial effects of the utility model are:

[0029] 1. The hemostatic pressure column is rotated to control the pressure degree in the hemostatic device, and the effect is more intuitive.

[0030] 2. The pressure point is directly opposite to the puncture site, which can achieve precise compression to stop bleeding and avoid local pressure damage to the puncture site. BRIEF DESCRIPTION OF THE DRAWINGS
