Description

Technical Field

[0001] The utility model relates to the technical field of medical supplies, in particular to a buckle-type tourniquet with a timer. Background Art

[0002] The tourniquet is made of natural rubber or special rubber, a medical polymer material, and is long and flat with strong elasticity. It is suitable for one-time use in medical institutions for infusion, blood drawing, blood transfusion, and hemostasis during routine treatment and rescue; or for emergency hemostasis in case of limb bleeding or snake and insect bite bleeding in the wild.

[0003] During the hemostasis process, the current hemostatic device has an airtight tourniquet in contact with the skin, and the sweat produced can contaminate the arterial puncture point. In addition, the pressure of the hemostatic device cannot be constant. Too much pressure can cause peripheral blood circulation disorders, while too little pressure can cause incomplete compression and form a hematoma.

[0004] For example, an automatic locking, timing-controlled radial artery compression hemostasis device disclosed in Chinese patent CN204890089U provides a predetermined compression time by adjusting the timer and time adjustment key on the front of the locking main part and observing the minutes displayed on the timer screen. After the arterial blood sampling is completed, the hemostatic disinfection cotton block is inserted into the hemostatic disinfection cotton block clip on the back of the lock main part, the hemostatic disinfection cotton block is padded at the radial artery puncture point on the wrist, the lock switch slide is pressed and the tourniquet is passed through the lock main part, the tourniquet is passed through the card slot and out, the lock switch slide is released, the lower lock buckle on the inner side of the lock switch slide is engaged with the corresponding upper lock buckle on the tourniquet to achieve an ideal compression state, the switch key is pressed, and when the time reaches the predetermined compression time, the buzzer on the LPC control chip alarms, the medical staff presses the lock switch slide, the lower lock buckle on the inner side of the lock switch slide is dislocated and separated from the corresponding upper lock buckle on the tourniquet, the tourniquet is pulled out, the automatic lock timing controllable radial artery compression hemostasis device is removed, the puncture point is disinfected again, the bleeding is completed, and the used hemostatic disinfection cotton block is removed and placed in the designated medical waste placement.

[0005] However, in the prior art, when using a tourniquet, the button-type timer is prone to accidental touches, causing the timer to be reset to zero or time confusion, thereby affecting the use effect.

[0006] For this reason we urgently need to provide a kind of buckle tourniquet with timer. Utility Model Content

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0028] Embodiment 1:

[0029] A buckle tourniquet with a timer comprises an elastic band 1. The outer surface of the elastic band 1 is connected with a clamping structure, a timing structure is installed on the top of the clamping structure, and a pressing structure is installed on the front and back of the clamping structure.

[0030] The timing structure includes a timing unit and a protection unit. The protection unit includes a button 204. A protection shell 205 is arranged outside the button 204. Limit bars 206 are installed on the front and back sides of the top of the protection shell 205. The outer surface of the limit bar 206 is connected to a protection plate 207. The timing unit includes a timer 201. A display screen 202 is installed in the middle of the top surface of the timer 201 near the back end. A buzzer 203 is installed inside the timer 201.

[0031] The button 204 is installed in the middle of the top surface of the timer 201 near the front end, the bottom surface of the protective shell 205 is fixedly connected to the middle of the top surface of the timer 201 near the front end, and the bottom surface of the protective plate 207 is slidably connected to the top surface of the protective shell 205.

[0032] By setting the timing structure, the protective shell 205 and the limit bar 206 installed on the top of the protective shell 205 can limit the protective plate 207, so that the protective plate 207 can slide the protective shell 205 to open and close, thereby protecting the button 204 and preventing the button 204 from being accidentally touched during use.

[0033] When in use, the timing time can be adjusted by pressing the button 204. After the timing time is adjusted, the protective plate 207 is pushed to utilize the sliding connection between the protective plate 207, the limit bar 206 and the top of the protective shell 205 to seal the protective shell 205, thereby preventing the button 204 from being accidentally touched. After the timing is over, the buzzer 203 is used to prompt.

[0034] Embodiment 2:

[0035] On the basis of the first embodiment, the clamping structure includes a lock buckle 101, a clamping buckle 102 is clamped inside the lock buckle 101, a bearing plate 103 is installed at the bottom of the lock buckle 101, a spring 104 is installed on the bottom surface of the bearing plate 103, and a rubber plate 105 is connected to the end of the spring 104 away from the bearing plate 103. The middle part of the right side of the lock buckle 101 is fixedly connected to one end of the elastic band 1, the end of the elastic band 1 away from the lock buckle 101 is connected to the left end of the clamping buckle 102, and the end of the spring 104 away from the rubber plate 105 is fixedly connected to the bottom surface of the bearing plate 103.

[0036] The pressing structure includes a fixing plate 301, a spring 2 302 is installed on the side of the two fixing plates 301 away from each other, a pressing block 303 is connected to the end of the spring 2 302 away from the fixing plate 301, and a pressing rod 304 is installed in the middle of the side of the pressing block 303 close to the spring 2 302. The fixing plate 301 is fixedly installed on the front and back right ends of the lock buckle 101, and the outer surface of the pressing rod 304 is slidably connected to the inner wall of the circular hole opened on the outer surface of the fixing plate 301.

[0037] By setting up the snap-connecting structure and the pressing structure and utilizing the installation of the spring 104 and the rubber plate 105, it is possible to prevent the hardness of the lock buckle 101 from squeezing the skin excessively and causing bruises and other injuries during use. The abutment of the rubber plate 105 and the stress of the spring 104 are utilized to increase the comfort level of use. At the same time, by pressing the pressing block 303 to drive the pressing rod 304 to squeeze the buckle 102, it is convenient to quickly release the locking state of the lock buckle 101 and the buckle 102.

[0038] When the elastic band 1 is used, the locking connection between the lock buckle 101 and the buckle 102 is utilized to stop bleeding. In this process, the rubber plate 105 is utilized to contact the skin away from the side of the spring 104, and the compressed stress of the spring 104 is utilized to produce extrusion, and the tourniquet is used in conjunction with the contraction force of the elastic band 1. The rubber plate 105 is utilized to prevent the hardness of the lock buckle 101 from squeezing the skin and causing damage and congestion. After the tourniquet is used, the pressing block 303 is driven to drive the pressing rod 304 to squeeze the buckle 102, thereby facilitating the release of the locking state of the lock buckle 101 and the buckle 102, and after the release, the pressing block 303 and the pressing rod 304 are reset by the compressive stress of the spring 2 302. Compared with releasing the locking state by pressing the buckle 102 by hand, the method is faster and more convenient, and it is not easy to cause damage to the hand caused by squeezing and friction when the buckle 102 is separated from the lock buckle 101.
