Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to an automatic tourniquet release mechanism. Background Technology

[0002] Tourniquets are made of medical-grade high-polymer materials, natural rubber, or special rubber. They are long, flat, and highly elastic. Suitable for single-use use in medical institutions for routine treatment and rescue procedures such as intravenous infusion, blood drawing, and transfusion; or for emergency hemostasis of limb bleeding or bleeding from snake or insect bites in the wild.

[0003] When performing punctures on patients, medical staff not only need to pay attention to the puncture itself, but also need to instruct patients to clench their fists to make the blood vessels clearer. At the same time, they need to use an elastic band to restrict blood flow to the puncture site. However, in actual punctures, there may be cases where the tourniquet is not loosened after the infusion puncture, which may lead to certain medical accidents.

[0004] How to provide an automatic tourniquet release mechanism is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0016] Beneficial effects:

[0017] This invention provides an automatic tourniquet release mechanism. When a tourniquet is needed for intravenous puncture, the main body of the tourniquet is attached to the patient's arm and locked in place by an electromagnetic lock. This tightens the tourniquet to control blood flow in the patient's veins. While the tourniquet is attached, the patient clenches their fist to grip the pressure bulb. This clenching helps to congest and expose the veins, allowing for puncture. After puncture, the patient is reminded to release their hand. The pressure bulb is no longer under pressure, and the pressure sensor receives a signal. This signal is converted into an unlocking signal for the electromagnetic lock and transmitted to it. The electromagnetic lock opens, releasing the tourniquet and relieving pressure on the patient's arm, thus completing the intravenous puncture process. This device automatically releases the tourniquet when the patient releases their fist, reducing the workload for medical staff. Furthermore, it allows for more timely and rapid tourniquet release, preventing medical accidents caused by forgetting to release the tourniquet and improving the efficiency of intravenous punctures.

[0026] The technical solutions in the embodiments of this specification will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this specification, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments in this specification are within the protection scope of this utility model.

[0027] Furthermore, in the embodiments of this specification, when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intervening component present. When a component is considered to be "set on" another component, it can be directly set on the other component or there may be an intervening component present.

[0028] Please see Figure 1-3 This embodiment provides an automatic tourniquet release mechanism, which includes a tourniquet body 1, the tourniquet body 1 including a main body 11 and an electromagnetic latch 12, the electromagnetic latch 12 being installed at one end of the tourniquet body 1; and a sensing component 2, the sensing component 2 including a pressure ball 21 and a pressure sensor, the pressure sensor being disposed inside the pressure ball 21 and being signal-connected to the electromagnetic latch 12.

[0029] Specifically, when a tourniquet is needed for intravenous puncture, the tourniquet body 11 is tied around the patient's arm, and the tourniquet body 11 is locked with the electromagnetic lock 12 to tighten the tourniquet body 11, thus controlling the blood flow rate in the patient's blood vessels. While the tourniquet body 11 is tied around the patient's arm, the patient needs to clench their fist and hold the pressure bulb 21. Clenching the fist helps to congest and expose the vein, allowing for the start of the puncture. After the puncture is completed, the medical staff reminds the patient to loosen their hand. When the pressure bulb 21 is no longer under pressure, the pressure sensor receives a signal and converts it into an unlocking signal for the electromagnetic lock 12, which is then transmitted to the electromagnetic lock 12. The electromagnetic lock 12 opens, the tightened tourniquet body 11 is released, the pressure on the patient's arm is relieved, and the entire infusion puncture process is completed. This device can automatically untie the tourniquet when the patient loosens their fist, reducing the operation steps for medical staff. At the same time, the tourniquet is loosened more promptly and quickly, avoiding medical accidents caused by medical staff forgetting to loosen the tourniquet, and improving the efficiency of infusion puncture for medical staff.

[0030] In some possible implementations, the electromagnetic lock 12 includes: an electromagnetic lock body 121, which is installed at one end of the tourniquet body 1; a permanent magnet 122, which is encased in a housing 123, with one end of the housing 123 rotatably connected to both sides of the electromagnetic lock body 121, and a gap is provided at the connection between the electromagnetic lock body 121 and the permanent magnet 122 for passage through the tourniquet body 1.

[0031] Specifically, when using the electromagnetic lock 12, firstly, with the connection between the electromagnetic lock body 121 and the housing 123 as the center, rotate the housing 123 to form an angle, separating the permanent magnet 122 inside the electromagnetic lock body 121 and the housing 123. Then, pass the other end of the belt body 11 through the gap between the electromagnetic lock body 121 and the housing 123, so that the belt body 11 forms a loop. The patient's arm is in the loop. Then, pull the other end of the belt body 11 to continuously reduce the diameter of the loop, thus compressing and tightening the patient's arm. When the required tightness is reached, rotate the housing 123 so that the permanent magnet 122 inside the housing 123 and the electromagnetic lock body 121 attract each other, thus clamping the belt body 11 and fixing the loop, thus compressing the patient's arm. When an opening signal is received, the electromagnetic lock body 121 is de-energized, the magnetism disappears, the permanent magnet 122 loses its attraction condition, the housing 123 and the electromagnetic lock 121 are no longer tightly attracted, and the belt body 11 loses its clamping and no longer generates pressure.

[0032] In some possible implementations, two rotating shafts 124 are respectively provided on both sides of the electromagnetic lock body 121, and two cantilever seats 125 are provided on both sides of one end of the housing 123 opposite to the two rotating shafts 124, and the two cantilever seats 125 are respectively sleeved on the two rotating shafts 124.

[0033] Specifically, the housing 123 is connected to the two rotating shafts 124 of the electromagnetic lock body 121 via the cantilever seats 125 on both sides, thereby enabling the housing 123 to rotate relative to the electromagnetic lock body 121, and completing the clamping and releasing of the main body 11 between the housing 123 and the electromagnetic lock body 121.

[0034] In some possible implementations, one end of the housing 123 is arc-shaped, and the other end of the housing 123 facing the electromagnetic lock body 121 is provided with a serrated claw 126. The main body 11 is an elastic band.

[0035] Specifically, when the housing 123 and the permanent magnet 122 are attracted to the electromagnetic lock body 121, the serrated claw 126 at the other end of the housing 123 increases the friction with the belt body 11, thus clamping the belt body 11 more tightly.

[0036] In some possible implementations, one end of the belt body 11 is located at the end of the electromagnetic lock body 121 near the cantilever seat 125, and one side of the belt body 11 is flush with the side of the electromagnetic lock body 121 near the housing 123.

[0037] Specifically, when the other end of the belt body 11 is clamped between the electromagnetic lock body 121 and the housing 123, the belt body 11 surrounds the two connected sides and is in contact with each other, so that the electromagnetic lock body 121 does not directly contact the patient's arm, thus avoiding discomfort to the patient caused by the relatively hard electromagnetic lock body 121.

[0038] In some possible implementations, the sensing component 2 further includes: a Bluetooth module disposed within the pressure ball 21, electrically connected to the pressure sensor, and signal-connected to the electromagnetic lock body 121. The sensing component 2 also includes: a controller mounted on the electromagnetic lock body 121, signal-connected to the pressure sensor; and a timer 22 mounted on the electromagnetic lock body 121, signal-connected to the controller.

[0039] Specifically, the pressure sensor on the pressure ball 21 is connected to the electromagnetic lock body 121 via a Bluetooth module. The Bluetooth connection is wireless, eliminating the need for wires between the pressure ball 21 and the electromagnetic lock body 121, thus improving the device's convenience. When performing other medical procedures such as blood draws on patients, the tourniquet may not be released at the same time as the patient releases their fist. This can be addressed by setting the controller and the timer 22 to set the interval between the release of the fist and the opening of the electromagnetic lock body 121. When the patient releases their fist, the pressure sensor receives a signal and transmits it to the controller and the timer 22. The timer 22 starts timing, and when the timing ends, the controller de-energizes the electromagnetic lock body 121, causing it to lose its magnetism and thus opening the electromagnetic lock buckle 12, thereby releasing the tourniquet.

[0040] In some possible implementations, the outer shell of the electromagnetic lock body 121 is made of an electromagnetically shielding material. The pressure ball 21 is shaped to be held in the hand.

[0041] Specifically, the outer side of the electromagnetic lock body 121, except for the side in contact with the permanent magnet 122, is covered with a shell 123 made of electromagnetic shielding material to prevent electromagnetic interference to the timer 22, controller, and Bluetooth module, etc. The pressure ball 21 and...
