a hemostatic device

Abstract

The invention discloses a hemostasis device. The hemostasis device comprises a shell, a control device and an oppressing plate; the control device is arranged in the shell, the oppressing plate is arranged outside the shell, and hemostasis cotton is detachably connected to the surface of the oppressing plate; the control device comprises a motor, a worm wheel, a worm, a driving shaft, a driving gear and a rack; a first supporting plate is fixedly connected to the inner wall of the shell, the motor is fixedly connected with the first supporting plate, a driving gear is fixedly connected to an output shaft of the motor, a driven gear is fixedly connected to the worm, and the driving gear is engaged with the driven gear; bearing bases are connected to the two ends of the driving shaft and fixedly connected with the inner wall of the shell, the worm wheel and the driving gear are fixedly connected with the driving shaft, the worm wheel is engaged with the worm, and the rack is engaged withthe gears, and drives the oppressing plate to move; the shell also comprises a switch assembly and pair of wrist bands. The hemostasis device is simple in structure, the hemostasis cotton can be replaced many times, a control assembly has the self-locking function, and meanwhile a pressure display and an alarm apparatus are arranged; the practicability is high.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, and in particular relates to a hemostatic device. Background technique [0002] At present, most of the hemostatic methods used in medical treatment are manual compression to stop bleeding, using sterile cotton balls or hemostatic bandages. In the actual implementation process, too much pressure is applied manually, which may easily cause numbness and shaking of the affected part of the patient, or even ischemia, and it is more likely to compress the artery. Blood vessels affect the patient’s recovery. Too little manual pressure can easily cause bleeding and edema in the patient’s affected area. This method of hemostasis requires manual finger pressure or bandaging, which increases the workload of medical staff, wastes time, and is difficult to control. , most of the existing hemostatic devices are airbag pressurized hemostats, which need to inflate and pressurize the airbag to achiev...

[0002] At present, most of the hemostatic methods used in medical treatment are manual compression to stop bleeding, using sterile cotton balls or hemostatic bandages. In the actual implementation process, too much pressure is applied manually, which may easily cause numbness and shaking of the affected part of the patient, or even ischemia, and it is more likely to compress the artery. Blood vessels affect the patient’s recovery. Too little manual pressure can easily cause bleeding and edema in the patient’s affected area. This method of hemostasis requires manual finger pressure or bandaging, which increases the workload of medical staff, wastes time, and is difficult to control. , most of the existing hemostatic devices are airbag pressurized hemostats, which need to inflate and pressurize the airbag to achieve compression and hemostasis on the affected area. The structure is generally complicated and difficult to operate
