Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular, to a timed tightening and loosening device for tourniquets. Background Technology

[0002] Tourniquets, as essential auxiliary tools for venipuncture and blood sampling, can temporarily block venous blood flow, causing local refill and improving the success rate of puncture. However, during clinical procedures, nursing staff often forget to remove the tourniquet after puncture due to factors such as a large number of patients, lack of proficiency, and a lack of responsibility and safety awareness. In severe cases, this can lead to medical accidents such as limb swelling or even ischemic necrosis, which is extremely detrimental to patient health and safety and the maintenance of medical order.

[0003] Existing technologies include some tourniquets with timed functions, such as Chinese Utility Model Patent Publication CN213697072U, which discloses an automatically release tourniquet, including a tourniquet, one end of which is fixedly equipped with an automatic release device, and the other end is connected to a connecting buckle. The automatic release device has a locking function with a set time. During the set time, it can be fixedly connected to the connecting buckle. When the set time ends, the two are disconnected and in a free state.

[0004] For example, Chinese utility model patent authorization announcement CN214907620U discloses a timed reminder tourniquet, including a fixing plate, with a strap fixed to each side of the fixing plate. One strap has hook-and-loop fasteners, and the other has fiber fasteners. A vibration alarm is installed on the fixing plate. In use, the tourniquet is tied to the user's body with the straps. After tying, the switch button S1 of the vibration alarm is pressed to start the timer. When the vibration alarm starts vibrating, it reminds the user to untie the tourniquet. After untying, the vibration alarm is retracted.

[0005] For example, Chinese utility model patent authorization announcement CN218220253U discloses an automatic tourniquet unlocking device, which includes a locking structure for setting the tourniquet in a taut state, an unlocking device for unlocking the locking structure and setting the tourniquet in a slack state, and a control circuit for controlling the unlocking device.

[0006] It can be seen that the above-mentioned unlocking devices are all used in conjunction with the tourniquet. This increases the overall cost of using the tourniquet and also brings the risk of cross-infection. Utility Model Content

Detailed Implementation

[0025] The present invention will now be described in detail with reference to the accompanying drawings.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] Figure 1 This is a side view of a timed tightening and loosening device for tourniquets according to the present invention.

[0028] As shown in the figure, a timed tightening and loosening device for a tourniquet includes: a body 1, a first channel 2, a second channel 3, a first button 4, a second button 5, a first pressing strip 6, and a second pressing strip 7. The first channel 2 and the second channel 3 are symmetrically arranged inside the body 1. The first button 4 is located above the first channel 2, and the first pressing strip 6 is connected below the first button 4. The second button 5 is located above the second channel 3, and the second pressing strip 7 is connected below the second button 5. A timer circuit (not shown) is provided inside the first button 4.
