Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and specifically relates to a pressure hemostasis nursing device. Background Technique

[0002] During clinical nursing, when a patient's arm or leg is traumatized and bleeding, it is necessary to apply pressure to stop bleeding on the patient's wound. Currently, the mainstream method generally uses a bandage or the like to apply pressure and bind it to the patient's wound, squeezing the wound to compress small blood vessels to achieve the purpose of hemostasis. For example, in a pressure hemostasis nursing device with the publication number CN202321933286.X, this device has the following deficiencies:

[0003] This device uses a binding band to tie a threaded sleeve ring to the traumatized bleeding position of the patient's limbs, and tries to make the patient's wound be at the center position of the threaded sleeve ring. Rotating the threaded column will drive the blood-absorbing cotton to move and squeeze the patient's wound position for pressing hemostasis. However, the coverage range of the threaded sleeve ring is small, and it is not possible to better achieve pressure hemostasis on the bleeding part and its periphery. Moreover, the method of rotating the threaded column to apply pressure to the wound cannot judge the pressing force on the wound. If the pressure is too large, it will cause discomfort to the patient, and if the pressure is too small, the hemostasis effect will be poor. Content of the Utility Model

[0033] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0034] Such as Figures 1 to 7As shown in the figure, the utility model provides a pressure hemostasis nursing device, which includes a pressure chamber 1 fixedly penetrating through the middle of a U-shaped buckle 5. The upper opening of the pressure chamber 1 is fixedly connected to a cabin cover 2 for sealing. On one side of the inner cavity of the pressure chamber 1, a pressure port 8 penetrating through the inner wall is opened. The inner cavity surface of the pressure port 8 is fixedly connected to the outer surface of a catheter 3, and the catheter 3 fixedly penetrates through the pressure port 8. One end of the catheter 3 far from the pressure port 8 is fixedly connected to one end of a pressure ball 4. On the outside of one side of the pressure chamber 1, a pressure gauge 10 is fixedly installed. The pressure gauge 10 is fixedly connected to the side of the catheter 3 close to the pressure port 8 and the inner cavities are communicated. By squeezing the pressure ball 4, air can be transported into the pressure chamber 1 through the catheter 3. By observing the pressure gauge 10, it can be judged whether the transported pressure meets the requirements. In the middle of the inner cavity of the pressure chamber 1, a pressing rod 15 is movably penetrated. The outer surface of the pressing rod 15 is slidably arranged on the inner ring surface of a sealing ring 9. The outer ring surface of the sealing ring 9 is fixedly glued to the middle opening of the pressure chamber 1. When the pressing rod 15 moves, the sealing ring 9 can prevent the pressure in the pressure chamber 1 from leaking, resulting in the inability to push the pressing rod 15 downward to press (as Figure 1 、 2 shown).

[0035] An adjustment mechanism 6 is arranged on the middle and lower surface of the pressing rod 15. The adjustment mechanism 6 includes a first limit ring 61 fixedly arranged on the outer surface of the middle of the pressing rod 15 in a circle. The lower part of the first limit ring 61 is fixedly connected to a sliding ring 62. The inner surface of the sliding ring 62 is also fixedly connected to the outer surface of the pressing rod 15. The outer surface of the sliding ring 62 is slidably connected to the inner surface of a sliding groove 63. When the sliding groove 63 and the sliding ring 62 slide relative to each other, they also limit each other. The sliding groove 63 is opened at the middle position of the inner surface of a ring plate 64. The lower surface of the ring plate 64 is fixedly connected to the upper surface of a pressing plate 11.

[0036] The adjustment mechanism 6 further includes a limit ball 65 fixedly arranged at the middle of the upper surface of one side of the ring plate 64. The upper surface of the limit ball 65 abuts against the inner surface of a limit groove 66 and limits each other. The limit grooves 66 are arranged in an array on the middle of the lower surface of the first limit ring 61. A plurality of limit grooves 66 opened at the middle of the lower surface of the first limit ring 61 are opposite to the limit ball 65. When the sliding groove 63 and the sliding ring 62 slide relative to each other and drive the ring plate 64 and the pressing plate 11 to rotate together, they are limited. The pressing plate 11 can adjust its position state according to the actual situation. On the outer surfaces of both sides of the ring plate 64, two symmetrically arranged bottom plates 67 are fixedly installed. On the surface of one side of the two bottom plates 67 far from the ring plate 64, they are fixedly connected to the surface of one side of two first connecting rods 68. On the surface of the middle of the upper surface of two second connecting rods 69, they are fixedly connected to the surface of the other side of the two first connecting rods 68 far from the bottom plates 67. The lower surfaces of the two second connecting rods 69 are fixedly connected to the upper surfaces of both sides of the pressing plate 11 (as Figure 3 、 4As shown, the two first connecting rods 68 and the two second connecting rods 69 can make the downward pressure received at both ends of the pressing plate 11 the same, and can uniformly achieve the pressing effect.

[0037] The lower surface of the U-shaped buckle 5 is glued to the upper surface of the U-shaped rubber pad 14. The U-shaped rubber pad 14 can fit better with the patient when clamping the patient's arm or thigh without making the patient too uncomfortable, and it is not easy to make the U-shaped buckle 5 rotate and separate from the patient's wound. The opening positions of the U-shaped buckle 5 are rotatably arranged with the wrist chain 13, and the surface of the wrist chain 13 in contact with the patient's skin is glued to one side surface of the soft rubber pad 12. Similarly, the soft rubber pad 12 glued to one side surface of the wrist chain 13 and the U-shaped rubber pad 14 glued to one side surface of the U-shaped buckle 5 have the same functions.

[0038] Locking mechanisms 7 are arranged on both side surfaces of the wrist chain 13. The two locking mechanisms 7 not only have the same structure but also the same installation method. The locking mechanism 7 includes a double L-shaped plate 71 fixedly connected to the outer surface of one side of the wrist chain 13. Both end surfaces of the double L-shaped plate 71 are fixedly connected to one side surface of the locking ring 72. The inner cavity surface of the locking ring 72 is in contact with and rotatable with the outer surface of the core column 74. One end of a spring 75 is fixedly connected to the inner cavity surface of one side of the core column 74, and the other end of the spring 75 is fixedly connected to one side surface of the locking buckle 76. The locking buckle 76 is fixedly connected to the inner surface of the outer ring 77 on the outer surface of one side of the spring 75. The outer ring 77 is slidably arranged in the inner cavity of the core column 74, and a circular ring is arranged at the opening position of the core column 74, so that the locking buckle 76 and the outer ring 77 can move inside the core column 74 without separating from the inner cavity of the core column 74. Squeezing the spring 75 can make the locking ring 72 and the locking buckle 76 more conveniently connected. The outer surface of the core column 74 away from the locking buckle 76 is fixedly connected to the inner surface of the second limiting ring 73, and the second limiting ring 73 is slidably arranged and rotatable with the surface of the locking ring 72 away from the locking buckle 76.

[0039] It should be noted that the components of the U-shaped buckle 5, the pressure chamber 1, the chamber cover 2, the pressing rod 15, and the adjustment mechanism 6 and the pressing plate 11 in this device are all made of transparent materials, and the pressure ball 4 and the pressure gauge 10 in this device are both existing structures, which will not be elaborated here.

[0040] The principle and process of the present utility model:

[0041] When the device is in use, by checking the bleeding position and wound size of the patient's arm, rotate and adjust the position of the pressing plate 11, so that the pressing plate 11 cooperates with the sliding ring 62 through the sliding groove 63, and then the limiting ball 65 on the upper part of the ring plate 64 abuts against and limits the limiting groove 66 on the lower part of the first limiting ring 61, so that the pressing plate 11 can maintain the adjusted angle according to the patient's wound and will not change. At the same time, put the U-shaped buckle 5 and the wrist chain 13 on the patient's arm or leg, and then, by comparing the size of the patient's arm or leg, connect and fix the locking ring 72 to the locking buckles 76 on both sides of the wrist chain 13 at a position suitable for the size of the patient's arm or leg. Press the locking buckle 76 into the inner part of the core column 74. The locking buckle 76 is stressed to squeeze the spring 75, and then put the locking ring 72 on the locking buckle 76. The spring 75 loses the extrusion force and pushes the locking buckle 76 to reset, firmly fixing the locking ring 72.

[0042] Next, just pinch the pressure ball 4 with the palm to pressurize the inside of the pressure chamber 1 through the catheter 3. The pressing rod 15 is pushed as the pressure inside the pressure chamber 1 increases, and moves downward until it drives the pressing plate 11 to completely fit the patient's wound. At this time, the medical staff adjusts the applied pressure by observing the value of the pressure gauge 10, adjusts the appropriate pressure according to the actual situation, and ensures the hemostasis effect without causing serious discomfort to the patient.
