Description

Technical Field

[0001] The utility model relates to the technical field of medical care products, in particular to an adjustable pressure hemostasis device. Background Art

[0002] After drawing blood, medical staff will usually cover the puncture needle hole with a cotton swab or cotton ball. The person whose blood is being drawn will press the cotton swab or cotton ball on the blood drawing point on the elbow for 2-3 minutes until the blood at the puncture needle hole coagulates and no longer bleeds, and then the cotton swab or cotton ball will be thrown away. Since the needle used in blood donation is thicker than the needle used in general blood collection for blood tests, and it stops bleeding more slowly, the following problems will become more prominent when using the above method to stop bleeding from the pinholes formed by blood donation: The first problem is that the effect of pressing to stop bleeding is poor. Since the pinholes formed by blood donation are large, the person whose blood is drawn generally needs to use appropriate force to gently press the pinholes for 5-10 minutes. Usually, after a few minutes of pressing, the arms and fingers of the person whose blood is drawn begin to feel sore. Subsequent pressing often causes changes in the pressure and slippage, which affects the hemostasis effect. Some people whose blood is drawn will even develop subcutaneous hemostasis around the puncture pinhole, which brings a bad blood donation experience to the blood donor. The second problem is that the blood donor needs to use one hand to press the puncture pinhole position of the other hand for a long time. During this period, both hands cannot engage in other activities, which is very inconvenient. When they have to use their hands, they will temporarily stop pressing, resulting in poor compression hemostasis.

[0003] Chinese patent document CN201029903Y discloses an auxiliary tourniquet, including a strip-shaped elastic belt body, a protrusion is provided in the middle of the belt body, and adhesive blocks are provided at both ends of the belt body. When in use, the protrusion in the middle of the belt body fixes the sterilized cotton ball on the puncture point. Although the above technical solution fixes the sterilized cotton ball by the elastic belt body, which frees the hands of the blood donor to a certain extent, it still has at least the following disadvantages: 1) The pressing force cannot be adjusted during use. When the pressing force needs to be adjusted, the belt body needs to be disassembled and then re-bonded. There is no pressing force during the re-bonding process, and the puncture point is prone to bleeding, and it is also easy to expose the puncture point and cause infection; 2) The elastic force of the belt body cannot be adjusted ideally, and the blood donor often cannot obtain a suitable pressing force; 3) The elastic force of the belt body is limited. For situations where a larger pressing force is required, the belt body may not meet the requirements.

[0004] Therefore, there is an urgent need for an adjustable pressure hemostasis device that can adjust the pressing force conveniently and quickly without exposing the puncture point. Utility Model Content

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the technical defects that the tourniquet in the prior art cannot accurately adjust the pressing force according to the needs of the blood donor during use, and the process of coarsely adjusting the pressing force requires the tourniquet to be disassembled and re-glued, which exposes the puncture point and increases the risk of infection.

The inside of the hemostatic cotton cavity 31 is used to place the hemostatic cotton, and the shape and size of the hemostatic cotton cavity 31 can be set according to the shape and size of the hemostatic cotton. When in use, first put the hemostatic cotton into the hemostatic cotton cavity 31, then point the end of the pressing plug 3 equipped with the hemostatic cotton toward the human arm, and cover the hemostatic cotton on the puncture point, and then fix the bandage 4 to the arm; rotate the pressure regulating cover 2 to move the pressing plug 3 toward the direction of the human arm, so that the hemostatic cotton is pressed tightly at the puncture point of the arm. The adjustable pressure hemostatic device of this embodiment can accurately control the axial movement distance of the compression plug 3 through the pressure regulating cover 2, so as to accurately adjust the force with which the compression plug 3 presses the hemostatic cotton against the arm. At the same time, when the force of pressing the puncture point needs to be adjusted during subsequent use, the pressure regulating cover 2 can be directly rotated without disassembling the belt body. Moreover, the entire adjustment process will not expose the puncture point and cause infection.

[0047] The adjustable pressure hemostasis device of this embodiment, the first connecting structure includes a first limiting portion 12 and a second limiting portion 22; the first limiting portion 12 is arranged at one end of the fixing sleeve 1 passing through the fixing hole 41, and is an annular flange formed on the outer wall of the fixing sleeve 1; the second limiting portion 22 is arranged at one end of the pressure regulating cover 2 close to the fixing sleeve 1, and is an annular flange formed on the inner wall of the mounting cavity 21; the inner diameter of the second limiting portion 22 is smaller than the outer diameter of the first limiting portion 12.

[0048] The adjustable pressure hemostatic device of this embodiment further includes a guiding structure 121 for guiding the first limiting portion 12 to be inserted into the interior of the mounting cavity 21; the guiding structure 121 is arranged on the first limiting portion 12, and is a conical surface formed on one end of the first limiting portion 12 facing the mounting cavity 21, and the outer diameter of the conical surface gradually decreases from the end away from the mounting cavity 21 to the end close to the mounting cavity 21, and the outer diameter of the conical surface at the smallest point is smaller than the inner diameter of the second limiting portion 22.

[0049] In this embodiment, the guide structure 121 is a conical structure, and the end close to the installation cavity 21 is the small end of the conical surface, and the outer diameter of the small end of the conical surface is the smallest, and the end away from the installation cavity 21 is the large end of the conical surface, and the outer diameter of the large end of the conical surface is the largest. The outer diameter of the small end of the conical surface is smaller than the inner diameter of the second limiting portion 22.

Under the action of external force, the conical structure slides along the inner side of the second limiting portion 22 and enters the interior of the installation cavity 21. When the first limiting portion 12 enters the interior of the installation cavity 21, since the inner diameter of the second limiting portion 22 is smaller than the outer diameter of the first limiting portion 12, the first limiting portion 12 is axially limited to prevent the first limiting portion 12 from detaching from the interior of the installation cavity 21.

[0054] The adjustable pressure hemostatic device of this embodiment also includes an anti-slip pad 5, which has a through hole 51 suitable for the first limiting portion 12 to pass through, and the inner diameter of the through hole 51 is smaller than the outer diameter of the second limiting portion 22; the outer diameter of the anti-slip pad 5 is larger than the inner diameter of the fixing hole 41; the other end of the fixing sleeve 1 is provided with a positioning portion 15, and the outer diameter of the positioning portion 15 is larger than the inner diameter of the fixing hole 41.

[0056] In the adjustable pressure hemostatic device of this embodiment, further, a plurality of protruding teeth 52 are formed on the inner peripheral wall of the through hole 51 of the anti-slip pad 5 .

[0057] In the adjustable pressure hemostatic device of this embodiment, further, the binding strap 4 is in the shape of an elongated strip, and two ends thereof are respectively provided with a first connecting portion 42 and a second connecting portion 43 which can be connected and fixed to each other.

[0061] Obviously, the above embodiments are merely examples for clear explanation, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description.
