Description

Compression-free hemostatic plaster

Technical Field

The utility model relates to a hemostatic patch, in particular to a push-free hemostatic patch.

Background

After venipuncture or intramuscular injection of patients with coagulation mechanism disorder, a bleeding part is usually pressed for a long time by holding a cotton swab or a simple infusion patch, so that the hemostatic effect is achieved. When hemostasis is carried out, a hand without venipuncture or intramuscular injection is often needed to press a bleeding part, and at the moment, if other medical matters need to be completed by holding personal belongings (files, bags and the like) on the other side, the operation of holding a cotton swab or simply pressing an infusion patch is very inconvenient. In addition, after intravenous puncture or intramuscular injection of old people, infants and persons without self-care ability, the situation of hemostasis by pressing can be completed with the help of medical staff or families.

Tourniquets in the prior art are used for arterial blood collection, compared with hemostasis after venipuncture or intramuscular injection, the hemostasis after arterial blood collection needs to apply larger pressure to a bleeding point and the pressing time is longer (about 30 minutes), and if the pressing force is insufficient, the result is dangerous. Therefore, the tourniquet used for arterial blood sampling hemostasis in the prior art is more complicated in structure. The tourniquet is disclosed in the Chinese patent application with the application number of CN201910305763X, the knob is screwed to enable the pressure stud to move downwards so as to press the arm to generate pressure, the rotating block is arranged, the pointer is driven to rotate through the rotating block, and different pressure values on the dial are pointed to realize the display of the pressure values.

Although the tourniquet has rich functions, the tourniquet is more suitable for hemostasis in arterial blood sampling. Firstly, the screwing of the knob is realized through threaded connection, the knob needs to be repeatedly rotated between a certain period, and for hemostasis of arterial blood sampling with strict guarantee of pressing force and longer pressing time, a certain period of time is required for adjusting the pressure to a proper size, but for hemostasis after venipuncture or intramuscular injection with pressing for seconds or minutes, a longer period of time is not required for adjusting the hemostasis pressure, and if the knob is repeatedly rotated, more time is required; secondly, the tourniquet is more complex in structure and higher in production cost, and cost waste can be caused on the premise that more functions are not needed.

As shown in fig. 1 and 2, the attaching part in this embodiment is an attaching cloth 3 with an area larger than the cross section of the first casing 1, the attaching cloth 3 includes a cloth layer and an adhesive layer disposed below the cloth layer, the cloth layer is made of soft materials used for sterile application in the prior art, such as non-woven fabrics, cotton cloth, PE films, and the adhesive layer is made of medical hot melt adhesive, acrylic adhesive, and the like in the prior art. The first shell 1 penetrates through the central position of the sticking cloth 3, two release papers 4 are attached to the adhesive layer of the sticking cloth 3, the edges of the two release papers 4 are aligned with the sticking part, and the pressing part is covered at the central position in a staggered mode.

As shown in fig. 3, the cross section of the first casing 1 is circular, the diameter of the lower half part of the first casing 1 is larger, the diameter of the upper half part of the first casing 1 is smaller, the lower half part and the upper half part are distinguished through fixing shoulders, that is, the fixing shoulders for matching with the adhesive cloth 3 are arranged on one side of the first casing 1 facing the human body, circular openings with the same size as the upper half part of the first casing 1 are arranged on the adhesive cloth 3, and the first casing 1 is sleeved in the circular openings. The upper end of the first shell 1 is of an opening structure, the lower end of the second shell 2 is sleeved in the upper end of the first shell 1 through a convex edge structure, and the relative position of the second shell 2 in the first shell 1 is adjusted through the convex edge structure. Specifically, the cross section of the second casing 2 is also circular, the upper end of the second casing 2 is of a closed structure, the diameter of the second casing 2, which is far away from one side of the first casing 1, namely the top end of the second casing 2, is larger, and anti-slip lines are arranged on the side walls, so that a screwing part 5 is formed, and a circle of side walls which are used for being matched with the first casing 1 are integrally and downwards extended below the screwing part 5. The inner wall of the upper opening structure of the first shell 1 is integrally provided with a first protruding edge 6 extending inwards along the circumference of the first protruding edge, 3 second protruding edges 7 matched with the first protruding edges 6 are integrally arranged on a circle of side wall extending below the second shell 2 along the height direction (namely the upper and lower directions), the longitudinal section of the first protruding edges 6 is a right triangle with an inclined edge obliquely upwards facing the second shell 2, the longitudinal section of the second protruding edges 7 is a right triangle with an inclined edge obliquely downwards facing the first shell 1, and the arrangement is that the first protruding edges 6 are abutted against different second protruding edges 7 by pressing the top of the second shell 2 downwards, so that the height of the second shell 2 is adjusted.

Of course, the outer wall of the first casing 1 and the inner wall of the second casing 2 may be provided with a first protruding edge 6 and a second protruding edge 7 which are matched with each other, and the upper end of the first casing 1 may be sleeved in the lower end of the second casing 2. The longitudinal sections of the first convex edge 6 and the second convex edge 7 can also be right-angled triangles, and the number of the second convex edges 7 and the interval between the two second convex edges 7 can be adjusted according to actual needs.

As shown in fig. 4, since the cross sections of the first housing 1 and the second housing 2 are both circular, the second housing 2 can rotate relatively in the first housing 1 (for the compression after venipuncture or intramuscular injection, the pressure of the pressing block 11 to the skin is not excessive, the second housing 2 can rotate), the first flange 6 is formed with 3 first slits 8 arranged in an array in the circumferential direction, where the first slits 8 refer to notches formed on the first housing 1, the first flange 6 is not disposed along a certain central angle, and in this embodiment, the central angle corresponding to each first slit 8 is 90 °. In the second convex edge 7, 3 second openings 9 which are matched with the first convex edge 6 and are arranged in an array are formed in the circumferential direction, wherein the second openings 9 refer to notches formed on the second shell 2 and are not arranged along a certain central angle of the second convex edge 7, and in the embodiment, the central angle corresponding to each second opening 9 is 30 degrees. So set up, when pressing the second casing 2 top more times and making pressure great, when needing to reduce the dynamics of pressing, rotatory portion of screwing 5 makes first opening 8 aim at second opening 9 (fig. 4 is the state that first opening 8 did not aim at second opening 9), then the protruding edge of first 6 just no longer looks with the protruding edge of second 7, and the second casing 2 upwards removes under compression spring 10's effect and reduces the pressure that the pressing part applyed to skin, and then reduces the dynamics of pressing. Further, three rotation prompting arrows may be respectively disposed on the outer walls of the first casing 1 and the second casing 2, each rotation prompting arrow corresponds to a central position of a corresponding opening, and when the rotation prompting arrows of the first casing 1 and the second casing 2 are aligned, the second casing 2 will rebound upwards. Although the screwing operation is also performed, continuous screwing is not needed, and trouble and labor are saved. In order to avoid the second casing 2 from being ejected from the first casing 1, the bottom end of a circle of side walls extending below the second casing 2 extends outwards to form a shoulder with a size larger than the largest size of the first flange 6, so that a limiting effect is achieved.

Of course, the number of the first openings 8 and the second openings 9 and the corresponding central angle can be adjusted according to the needs.

As shown in fig. 3, the pressing portion is fixed to the bottom of the second housing 2 by a compression spring 10. Specifically, the middle part below the second casing 2 is also integrally provided with a mounting part for connecting the compression spring 10, the upper end of the compression spring 10 is fixedly sleeved on the mounting part, and the lower end of the compression spring 10 is fixedly sleeved on the pressing part. A through hole having a size slightly larger than the cross section of the pressing part is formed in the bottom surface of the first housing 1, so that the pressing part passes through, and the bottom surface of the pressing part protrudes from the bottom surface of the first housing 1. The pressing part comprises a pressing block 11, a hemostatic layer 12 is fixedly arranged on the bottom surface of the pressing block 11, namely the surface facing the skin, the hemostatic layer 12 is made of artificial adhesive cotton fibers and spunlaced non-woven fabrics, and the hemostatic layer can also be made of water-absorbing inner core materials of other sterile application or band-aid in the prior art. The pressure of the pressing portion against the bleeding point depends on the degree of protrusion of the pressing portion on the bottom surface of the first housing 1 and the hooke's coefficient of the compression spring 10, and the initial pressure against the skin when the second housing 2 is not pressed in the present embodiment can be adjusted by adjusting the above two parameters.

In order to make wearing more comfortable, the outer edge of the first shell 1 is designed with a chamfer, so that one surface of the first shell 1 facing the human body is an arc surface, and similarly, the outer edge of the lower end of the pressing block 11 can be designed with a chamfer, so that one surface of the pressing block 11 facing the human body is also an arc surface. In this embodiment, the first casing 1, the second casing 2, and the pressing block 11 are all made of transparent plastic material (section line type is only used for illustration in the figure), so as to observe the bleeding condition of the bleeding point, and the pressing-free hemostatic patch of this embodiment is a sterile hemostatic patch.

When the embodiment is used, the two ends of the adhesive cloth 3 are bent, the release paper 4 which is staggered to cover the pressing parts is separated, the pressing parts are exposed, the pressing parts are aligned with the bleeding points and pressed on the bleeding points, the release paper 4 is torn off, the adhesive cloth 3 is adhered to the skin, the pressing parts can play the effect of stopping bleeding without pressing by hands, the whole process is about 1 second, and the operation is convenient and quick. In the initial state without additional operations, most of the rapid hemostatic compression after venipuncture or intramuscular injection can be basically satisfied. If special conditions occur, the pressing force needs to be increased, and the top of the second shell 2 is pressed, so that the second shell 2 moves downwards until the required pressing force is achieved. If the pressing force needs to be reduced at this time, the rotating screw part 5 aligns the rotating prompt arrows of the first shell 1 and the second shell 2, and the second shell 2 can rebound upwards, so that the pressing force is reduced.
