Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a tourniquet. Background Art

[0002] In order to reduce the amount of bleeding, during orthopedic limb surgery and rescue, a tourniquet needs to be tied to the patient for effective hemostasis. In order to improve the hemostasis effect, the tourniquet will be tied very tightly, and accordingly, the binding force will be relatively large. Therefore, if the tourniquet is not loosened in time, blood flow will be blocked.

[0003] In the prior art, tourniquets are usually equipped with a timing device and a sound alarm to remind medical staff to untie the patient in time. However, when the patient is in a noisy environment such as a battlefield or the wild, the sound emitted by the sound alarm may be covered by the surrounding sounds, making it difficult for medical staff to untie the patient in the first time, which may cause local blood circulation obstruction and local necrosis in the patient's limbs.

[0004] Therefore, a tourniquet is needed to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a tourniquet, which can remind medical staff to loosen the tourniquet wrapped around the patient's limbs by adding a visual reminder on the basis of the sound alarm reminder, thereby improving the safety during use and preventing local blood obstruction or necrosis of the patient's limbs due to the tourniquet being tied for too long.

[0006] In order to solve the above technical problems, the utility model provides a tourniquet, including a mounting seat, a belt body, a liner, a timing member, a spray member and a control drive member;

[0007] The belt body is arranged on both sides of the mounting seat, and two belt bodies can be connected;

[0008] The pad is arranged on the inner side of the two belt bodies;

[0009] The timing component, the spraying component and the control driving component are all arranged inside the mounting seat;

[0010] The timing member is electrically connected to the control drive member, and the control drive member is connected to the driving end of the spray member;

[0011] When the timing part reaches the preset time, the control driving part is driven to control the spraying part to operate;

[0012] The spraying piece contains a dyeing solution for easy identification, and a spraying port of the spraying piece faces the pad.

[0013] Furthermore, the control drive component includes a power supply and an electromagnet;

[0014] The electromagnet is connected to the driving end of the spraying member;

[0015] The power source, the electromagnet and the timing element are connected in pairs through wires to form a closed circuit;

[0016] When the timing member reaches a preset time, the closed circuit is in a connected state, so that the electromagnet pushes the driving end of the spraying member to operate.

[0017] Furthermore, the spraying member includes a spraying cylinder and a piston push rod;

[0018] The spraying tube is fixedly mounted inside the mounting seat;

[0019] The piston push rod is slidably mounted inside the spray barrel and has an exposed end;

[0020] A gap is reserved between the exposed end and the electromagnet, and the exposed end is provided with a permanent magnet material.

[0021] Furthermore, when the closed circuit is in a connected state, the electromagnet can provide a repulsive force to the exposed end, thereby controlling the exposed end to move in a direction close to the spray barrel, so that the dyeing solution is sprayed out from the spray port of the spray barrel.

[0022] Furthermore, an elastic member is provided between the exposed end and the spraying tube for pulling the exposed end to reset.

[0033] The tourniquet of the present invention will be described in more detail below in conjunction with a schematic diagram, wherein a preferred embodiment of the present invention is shown, and it should be understood that those skilled in the art can modify the present invention described herein while still achieving the beneficial effects of the present invention. Therefore, the following description should be understood as being widely known to those skilled in the art, and not as a limitation to the present invention.

[0034] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the accompanying drawings are in very simplified form and in non-precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0035] like Figures 1 to 3 As shown, the embodiment of the utility model provides a tourniquet, which includes a mounting seat 1, a belt body 2, a pad 3, a timing member 4, a spraying member 5 and a control driving member 6.

[0036] The belt body 2 is arranged on both sides of the mounting seat 1, and the two belt bodies 2 can be connected to bind the patient's affected limb to achieve the function of hemostasis.

[0037] The pad 3 is arranged on the inner side of the two belt bodies 2 to fit the affected part of the patient as a medium layer and play a major role in hemostasis.

[0038] It should be noted that the pad 3 should be soaked with an alcohol solution to disinfect the affected part of the patient. Preferably, the pad 3 can also be set as an independent package, and the pad 3 and the belt body 2 can be detachably connected (such as by Velcro). By setting the pad 3 as an independent package, it can effectively prevent the pad 3 from being exposed to the air for a long time and causing bacterial contamination; and by setting the pad 3 and the belt body 2 as a detachable connection, it is convenient to recycle the pad 3, and under the positioning effect of the Velcro, it can also ensure that the pad 3 will not be misplaced during the winding process of the tourniquet, thereby affecting the fitting effect.

[0039] The timing component 4 , the spraying component 5 and the control driving component 6 are all arranged inside the mounting seat 1 .

[0040] The timing member 4 is electrically connected to the control drive member 6, and the control drive member 6 is connected to the driving end of the spray member 5, and when the timing member 4 reaches a preset time, the control drive member 6 is driven to control the spray member 5 to operate. That is, after the medical staff has completed the binding of the patient's affected limb, the timing member 4 can be used to preset the control drive member 6 to control the spray member 5 to operate (i.e., the spray member 5 sprays).

[0041] It should be noted that the spraying member 5 has a built-in dyeing solution for easy identification, and the spraying port of the spraying member 5 faces the pad 3. The spraying member 5 can spray the dyeing solution on the pad 3 when spraying. Since the pad 3 is usually made of white cotton, when the dyeing solution is sprayed on the pad 3, the pad 3 can be dyed, so that medical staff can judge whether the binding time of the tourniquet reaches the preset time by observing the color change of the pad 3, thereby realizing the function of visual reminder.

[0042] The device is provided with a timing member 4, a control drive member 6 and a spray member 5, and the timing member 4 is electrically connected to the control drive member 6 and the control drive member 6 is connected to the driving end of the spray member 5, so that when the belt body 2 and the pad 3 are tied to the patient's limb for a preset time, that is, when the timing member 4 reaches the preset time, the control drive member 6 can drive the spray member 5 to operate to spray the dye solution on the pad 3, and then remind the medical staff to loosen the tourniquet wrapped around the patient's limb through the change of color of the pad 3, that is, realize the function of visual reminder, and effectively improve the safety of the tourniquet when used.

[0043] In this embodiment, a specific control driving member 6 is provided to better cooperate with the timing member 4 and complete the function of driving the spraying member 5 .

[0044] Specifically, the control drive component 6 includes a power supply 61 and an electromagnet 62 .

[0045] The electromagnet 62 is connected to the driving end of the spraying member 5 .

[0046] The power source 61, the electromagnet 62 and the timing element 4 are connected in pairs through wires to form a closed circuit.

[0047] When the timing member 4 reaches the preset time, the closed circuit is in a connected state, so that the electromagnet 62 pushes the driving end of the spraying member 5 to operate. That is, when the timing member 4 reaches the preset time (i.e., the tourniquet binding time), the electromagnet 62 is in a powered state, and the magnetic characteristics of the electromagnet 62 are used to complete the control of the driving end of the spraying member 5.

[0048] Specifically, the spraying member 5 includes a spraying cylinder 51 and a piston push rod 52 .

[0049] The spray barrel 51 is fixedly mounted inside the mounting base 1, and the piston push rod 52 is slidably mounted inside the spray barrel 51 (i.e., serving as the driving end of the spray member 5), so that when the piston push rod 52 moves toward the inside of the spray barrel 51, the dyeing solution inside the spray barrel 51 can be squeezed out to stain the pad 3, thereby serving as a reminder to medical staff.

[0050] The piston push rod 52 has an exposed end 521 , and a gap is reserved between the exposed end 521 and the electromagnet 62 , and the exposed end 521 is made of a permanent magnet material.

[0051] like Figure 2 and Figure 3 As shown, when the closed circuit is in a connected state, the electromagnet 62 can provide a repulsive force to the exposed end 521, control the exposed end 521 to move in a direction close to the spray barrel 51, and make the dyeing solution spray out from the spray port of the spray barrel 51 to complete the dyeing of the pad 3, thereby serving as a visual reminder for medical staff.

[0052] In other embodiments, an elastic member is provided between the exposed end 521 and the spray barrel 51 for pulling the exposed end 521 to reset, that is, when the electromagnet 62 is in a power-off state, the electromagnet 62 no longer provides repulsive force to the exposed end 521, and the exposed end 521 can be reset under the action of the elastic member to wait for the next operation.

[0053] It should be noted that the elastic member is configured as a spring. Since the spring is made of spring steel, the material does not form an adsorption force with the electromagnet 62, so the normal operation of the equipment can be guaranteed.

[0054] In addition, a filling head 511 for filling the dyeing solution, that is, for replenishing the liquid, is provided on the upper surface of the spraying tube 51 .

[0055] The dyeing solution is iodine tincture, which can turn the liner 3 yellow after being stained by iodine tincture, so it can play a role of visual reminder, and spraying iodine tincture on the liner 3 can also play a further sterilization and disinfection effect.

[0056] In this embodiment, the timing element 4 is configured as a mechanical timer to realize the function that the timing element 4 can form a closed circuit with the power supply 61 and the electromagnet 62 after reaching a preset time. For details, reference may be made to a mechanical timer proposed in the existing patent publication number CN206774453U, which is a prior art and will not be described in detail here.

[0057] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
