A kind of novel tourniquet
Technical field
This utility model relates to a kind of novel tourniquet.
Background technology
Hospital medical, check, blood transfusion, venous blood samples sample etc. are all used tourniquet now, and tourniquet easily causes cross infection when a lot of patients use, arm-rest belt is close to skin cross infection risk and is increased, and the tourniquet complex structure disinfection cycle of each all automatic disinfections is long, affect work efficiency, be unfavorable for spread, restricted the popularization of tourniquet.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of novel tourniquet that can automatically change arm-rest belt.
this utility model adopts following technical scheme: this utility model comprises the tourniquet support, be fixedly installed on the liner plate on support, be fixedly installed on the guide wheel of support one side, the secondary guide wheel corresponding with the guide wheel position that is fixedly installed on the support opposite side, be fixedly installed on the active winding up roller of pressing the arteries and veins motor that is provided with on support, be fixedly installed on the driven winding up roller of secondary guide wheel one side on support, described active winding up roller is connected with gear on driven winding up roller by driving rack, be fixedly installed an end between described active winding up roller and guide wheel with the lifting take-up rod of roller, described lifting take-up rod is arranged on the tourniquet support by tightening up actuating device, on described driven winding up roller, volume is equipped with arm-rest belt, described arm-rest belt is by secondary guide wheel, guide wheel is wrapped on the active winding up roller, be provided with the arm-rest belt electromagnetic lock between described active winding up roller and lifting take-up rod.
Good effect of the present utility model is as follows: use tourniquet of the present utility model, avoided many people to use same arm-rest belt and the probability of cross infection has occured, replacing arm-rest belt simple in structure carries out fully automatically, and the time is short thoroughly clean, improves the work efficiency of tourniquet.
Description of drawings
Accompanying drawing 1 is this utility model structural representation;
Accompanying drawing 2 is the new veiny attitude structural representation of pressing of this practicality.
In the accompanying drawings: 1 tourniquet support, 2 liner plates, 3 lifting take-up rod, 4 guide wheels, 5 secondary guide wheels, 6 arm-rest belts, 7 arm-rest belt electromagnetic locks, 8 driven windings up roller, 9 initiatively winding up roller, 10 driving racks, 11 press arteries and veins motor, 12 to tighten up actuating device, 13 rollers, 14 arms.
The specific embodiment
as shown in Figure 1, this utility model comprises tourniquet support 1, be fixedly installed on the liner plate 2 on support 1, be fixedly installed on the guide wheel 4 of support 1 one sides, the secondary guide wheel 5 corresponding with guide wheel 4 positions that is fixedly installed on support 1 opposite side, be fixedly installed on the active winding up roller 9 of pressing arteries and veins motor 11 that is provided with on support 1, be fixedly installed on the driven winding up roller 8 of secondary guide wheel 5 one sides on support 1, described active winding up roller 9 is connected with gear on driven winding up roller 8 by driving rack 10, be fixedly installed an end between described active winding up roller 9 and guide wheel 4 with the lifting take-up rod 3 of roller 13, described lifting take-up rod 3 is arranged on tourniquet support 1 by tightening up actuating device 12, on described driven winding up roller 8, volume is equipped with arm-rest belt 6, described arm-rest belt 6 is by secondary guide wheel 5, guide wheel 4 is wrapped on active winding up roller 9, be provided with arm-rest belt electromagnetic lock 7 between described active winding up roller 9 and lifting take-up rod 3.
The patient is put into arm 14 and is enclosed within on tourniquet liner plate 2 in arm-rest belt 6 in use, presses this moment arteries and veins motor 11 not work owing to adopting the rack-and-pinion transmission between active winding up roller 9 and driven winding up roller 8, and active winding up roller 9 and driven winding up roller 8 can not rotated.tighten up actuating device 12 and promote lifting take-up rod 3, the roller 13 on lifting take-up rod 3 tops promotes arm-rest belt 6, can tighten up arm-rest belt 6 produces the pressure arteries and veins to arm 14 under the guiding of guide wheel 4 and secondary guide wheel 5 effect by automatic operation, reach the numerical value of setting when arm-rest belt 6 after, arm-rest belt 6 no longer tightens up, avoid tension to bring discomfort with the protection patient, arm-rest belt 6 maximum pressures can regulate to adapt to different patients, when arm-rest belt 6 in the situation that manually there is no release, tightening up actuating device 12 when pressing the arteries and veins time to reach preset value can quit work, arm-rest belt 6 automatic unlockings namely tighten up actuating device 12 drive lifting take-up rod 3 and move down, avoid pressing the arteries and veins overlong time that the patient is damaged, then press 11 work of arteries and veins motor, drive and initiatively roll up rod 9, drive driven winding up roller by driving rack 10 simultaneously, initiatively rolling up rod 9 will roll with the arm-rest belt 6 of crossing, original arm-rest belt 6 in driven volume rod 8 is exported on tourniquet, driven volume rod 8 is emitted original arm-rest belt 6, use tourniquet of the present utility model, avoided many people to use same arm-rest belt 6 and the probability of generation cross infection, this utility model replacing arm-rest belt simple in structure carries out fully automatically, time is short thoroughly clean, improve the work efficiency of tourniquet.When this utility model tightens up actuating device 12 work, active winding up roller 9 and driven winding up roller 8 do not rotate, for the locked intensity of strengthening arm-rest belt 6 can be installed arm-rest belt electromagnetic lock 7 between active winding up roller 9 and lifting take-up rod 3, press arteries and veins motor 11 work arm-rest belt electromagnetic locks 7 to open, press the arteries and veins motor 11 arm-rest belt electromagnetic lock 7 that quits work locked.
