DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0023] Reference Figures 1-5 A back type digital display compression tourniquet, comprising a connecting plate 1, a pressurizing assembly is arranged on the connecting plate 1, and a plurality of bandages 2 are fixedly connected to the connecting plate 1, and an electric control assembly is further arranged on the connecting plate 1.

[0024] Among them, the bandage 2 adopts nylon material, and the bandage 2 is provided with a hook and loop fastener at both ends, which is basically the same as the bandage 2 in the prior art.

[0025] The pressurizing assembly comprises a connecting sleeve 3, a pressure rod 4 is slidably connected in the connecting sleeve 3, a pressure plate 5 is fixedly connected to the pressure rod 4, a compression spring 6 is fixedly connected to the upper end of the pressure rod 4, a tapered block 7 is fixedly connected to the end of the compression spring 6 away from the pressure rod 4, a plurality of drive rods 8 are slidably connected to the connecting plate 1, and the drive rods 8 are arranged in abutment with the tapered block 7, a drive plate 9 is further rotatably connected to the connecting sleeve 3, the drive rods 8 are slidably connected with the drive plate 9, a toothed plate 10 is further fixedly connected to the drive plate 9, a limiting sleeve is arranged on the connecting plate 1, and a toothed groove 11 matched with the toothed plate 10 is formed in the limiting sleeve;

[0026] In this design, the connecting sleeve 3 is matched with the pressure rod 4, the compression spring 6 provides elastic force, and the compression effect on the puncture point of the patient is ensured. Since the puncture point is close to the chest, it will fluctuate slightly with the patient's breathing, so the compression spring 6 is arranged to ensure the compression effect on the puncture point.

[0027] After the patient is punctured, the tourniquet is fixed on the patient's body by the bandage 2, the pressure plate 5 is positioned at the puncture point on the patient's body surface, then the bandage 2 is tightened, the medical staff slightly presses the driving plate 9, the tooth plate 10 is separated from the tooth groove 11, then the driving plate 9 is rotated, the driving plate 9 drives the plurality of driving rods 8 to move towards each other and abut against the tapered block 7, thereby driving the pressure rod 4 to move towards the patient's body surface, until the pressure plate 5 meets the hemostasis requirement on the patient's body surface, then the medical staff slides the driving plate 9 to make the tooth plate 10 and the tooth groove 11 be clamped, and then completely releases the driving plate 9, so that the whole compression hemostasis process is completed. It should be noted that during the pressure operation, the position of the driving plate 9 is slightly adjusted, which has little effect on the whole compression hemostasis operation (the pressure safety range of the upper limb tourniquet is within 40 kPa). The design is mainly used to optimize the thickness of the tourniquet. When the patient wears the tourniquet, he can also wear a well-fitting hospital gown on his body, without waiting for hemostasis to be completed naked. This not only improves the comfort of the patient, but also makes the patient more comfortable psychologically.

[0028] Further, the electric control assembly includes a shell 12 fixedly connected with the connecting plate 1, an electric control module is arranged in the shell 12, the electric control module is electrically connected with a pressure sensor, and the pressure sensor is arranged in the pressure plate 5. A display screen 13 is further embedded on the shell 12, and the display screen 13 is electrically connected with the electric control module.

[0029] In the design, the display screen 13 cooperates with the pressure sensor. After the bandage 2 is tightened and the pressure plate 5 is used to compress the hemostasis position, the user observes the value of the display screen 13 while performing the pressure operation. When the required pressure is reached, the pressure operation is stopped, so that the pressure of the compression hemostasis is conveniently controlled. In addition, the electric control module is further provided with a timing system, which is used to time after the pressure operation is completed, so that the compression hemostasis time is conveniently controlled.

[0030] Further, a buzzer alarm is further arranged in the shell 12, and the buzzer alarm is electrically connected with the electric control module.

[0031] The buzzer alarm can prompt the user to remove the tourniquet when the compression hemostasis time reaches the set value.

[0032] Further, the driving plate 9 includes a connecting ring 91 rotationally connected with the connecting sleeve 3, a circular sleeve 92 is slidably connected with the connecting ring 91, an arc plate 93 is fixedly connected with one end of the circular sleeve 92 away from the connecting ring 91, a plurality of arc-shaped sliding grooves 94 are formed in the arc plate 93, a sliding block matched with the arc-shaped sliding grooves 94 is fixedly connected with the driving rod 8, the tooth plate 10 is fixedly connected with the arc plate 93, and an elastic pad 95 is fixedly connected with a position of the arc plate 93 close to the tooth plate 10.

[0033] In the design, the elastic pad 95 is arranged to drive the toothed plate 10 to return to the initial position after the pressing is completed, so that the toothed plate 10 is combined with the toothed groove 11, and the pressing assembly is loosened under the driving of the reaction force. The arc-shaped sliding grooves 94 can drive the driving rods 8 to move towards each other when the arc surface plate 93 rotates, so as to ensure that the driving rods 8 can drive the pressing rods 4 to press the pressing plate 5.

[0034] Further, the arc surface plate 93 is further fixedly connected with the rectangular block 14, and the rectangular block 14 is arranged to facilitate the user to rotate the arc surface plate 93 and operate the pressing assembly.

[0035] Further, the number of the bandages 2 is three, and when the patient wears the tourniquet, the three bandages 2 are respectively bound at the axillary and shoulder of the patient on both sides and are fixed at the back of the patient as a node. The three bandages 2 can ensure that the pressing assembly is not laterally displaced, and also make the moving stroke of the pressing plate 5 required to reach the pressure of the compression hemostasis smaller after the bandage 2 is bound, so as to finally reduce the thickness of the compression hemostasis device, so that the patient can normally wear a hospital gown when wearing the tourniquet.

[0036] The above is only the preferred specific implementation mode of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
