Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically to a rapid cutting device for disposable tourniquets used in emergency care. Background Technology

[0002] Tourniquets are widely used as consumables in many medical procedures such as blood drawing, hemostasis, and intravenous infusion. Traditional tourniquets are generally rubber tubing or rubber strips. When used, medical staff apply the tourniquet to the patient's arm to compress the blood vessel, thereby stopping the bleeding or making the vessel prominent. These tourniquets are usually reused and only replaced when they become worn or break. With advancements in medical technology, and considering the risk of cross-infection between patients due to reusable consumables, the above-mentioned type of tourniquet has gradually been phased out. It has been replaced by a new type of tourniquet: a flat, disposable strip that is single-use. This greatly improves the convenience for medical staff and reduces the risk of cross-infection.

[0003] The aforementioned tourniquets are generally shipped in rolls. When using them, the tourniquet needs to be manually pulled out of the roll to an appropriate length, then cut with scissors, and then tied to the patient's arm. This method requires special scissors and is too cumbersome, affecting the efficiency of hemostasis. Especially in the emergency department, faster hemostasis is very important. In addition, when pulling out the tourniquet, the entire tourniquet is easily exposed, and blood and other stains can easily splash onto the tourniquet, causing contamination.

[0004] Therefore, it is necessary to make further improvements to the existing technology. Utility Model Content

[0066] The following describes in detail, with reference to the accompanying drawings, an emergency disposable tourniquet quick-cutting device according to an embodiment of the present invention.

[0067] Reference Figures 1 to 5 As shown, an emergency disposable tourniquet rapid cutting device according to an embodiment of the present invention includes a housing 10, a guide nozzle 104, a clamping component 20, and a cutting component 30.

[0068] The housing 10 has a receiving cavity 101 and a rotating shaft 102 that can rotate along the axis of the housing 10 for winding the tourniquet. The tourniquet is wound on a hollow sleeve. The hollow sleeve can be directly inserted into the rotating shaft 102, which makes it easier to feed the tourniquet. The side of the housing 10 has a tourniquet outlet 103, which is connected to the receiving cavity 101.

[0069] The guide nozzle 104 is located on the side of the housing 10. The guide nozzle 104 has a guide channel 1041 inside. The guide channel 1041 is connected to the outlet 103 and is used to guide the tourniquet out from the guide nozzle 104.

[0070] The clamping member 20 is provided on the guide tube nozzle 104 to clamp the tourniquet inside the guide tube nozzle 104 and prevent the tourniquet from retracting.

[0071] The cutting component 30 is disposed on the guide nozzle 104 and located in front of the clamping component, for cutting the tourniquet.

[0072] Based on the above, in use, the entire roll of tourniquet can be wound onto the rotating shaft 102, and its end can be inserted through the outlet 103 into the guide nozzle 104 for use. This avoids the entire roll of tourniquet being exposed and contaminated. After the tourniquet has been drawn out to the required length, it can be cut by the cutting member 30. The cutting method is simple and quick, and no additional scissors are needed. At the same time, the clamping member 20 is set to clamp the tourniquet, so that the end of the tourniquet will not retract after being cut, making it easy to use again next time. The overall structure of this utility model is simple, convenient to use, highly practical, and effective.

[0073] Preferably, in one embodiment of the present invention, the pressing member 20 includes a first roller 201 and a second roller 202.

[0074] The first roller 201 is rotatably mounted on the bottom surface of the belt conveyor 1041.

[0075] The second roller 202 is positioned above the tourniquet passage 1041 and clamps the tourniquet through the first roller 201 and the second roller 202.

[0076] The second roller 202 can be adjusted between a first position and a second position. When the second roller 202 is in the first position, the second roller 202 is against the first roller 201. When the second roller 202 is in the second position, the second roller 202 is away from the first roller 201.

[0077] Thus, when the second roller 202 is in the first position, the tourniquet can be clamped to prevent the cut end of the tourniquet from retracting and becoming unusable next time. At the same time, when it is necessary to replace or add a tourniquet, the second roller 202 can be adjusted to the second state, so that a gap is created between the first roller 201 and the second roller 202, so that the end of the new tourniquet can pass smoothly through the first roller 201 and the second roller 202.

[0078] Preferably, in one embodiment of the present invention, a connecting arm 203 is provided at both ends of the second roller 202, and two through slots 1042 are provided at the top of the belt passage 1041, with the two connecting arms 203 respectively passing through the two through slots 1042.

[0079] The connecting arm 203 has a rotating part 204 on its side. The rotating part 204 is rotatably connected to the groove wall of the through groove 1042. A torsion spring 205 is provided on the rotating part 204.

[0080] The two connecting arms 203 are provided with a pressing part 206 at their upper ends, which facilitates driving the second roller 202 to rotate between the first position and the second position.

[0081] Thus, by setting the rotating part 204, when it is necessary to adjust the second roller 202 from the first position to the second position, the pressing part 206 can be pressed, so that the connecting arm 203 can rotate along the rotating part 204, thereby driving the first roller 201 to move away from the second roller 202. When the pressure on the pressing part 206 is released, the torsion spring 205 can drive the second roller 202 from the second position back to the first position. The adjustment method is simple, reliable, quick and labor-saving.

[0082] Preferably, in one embodiment of the present invention, a rotating column 2011 is connected to one end of the first roller 201, and the rotating column 2011 extends to the outside of the guide nozzle 104 to drive the first roller 201 to rotate.

[0083] It is understood that the cutting component 30 is located within the tourniquet passage 1041 to avoid accidental injury. However, after the tourniquet is cut, the end of the tourniquet is located within the tourniquet passage 1041 to avoid long-term exposure, but this makes it impossible to retrieve the end for the next use. Therefore, by setting the rotating column 2011 to drive the first roller 201 to rotate, the end of the tourniquet is conveyed to the guide nozzle 104 outlet for easy retrieval by medical personnel. Of course, to prevent the tourniquet end from accidentally retracting due to accidental rotation of the first roller 201, a damping component can also be fitted on the rotating column 2011 to increase its rotational resistance and prevent accidental rotation.

[0084] Preferably, in one embodiment of the present invention, a rotating block 2012 is provided at the end of the rotating column 2011 to facilitate the rotation of the rotating column 2011 by means of the rotating block 2012.

[0085] It should be noted that the diameter of the rotating block 2012 is larger than that of the rotating column 2011, which makes it easier for the operator to hold it and makes it easier and less strenuous to rotate the rotating column 2011.

[0086] Preferably, in one embodiment of the present invention, the cutting member 30 includes a sliding block 301 and a cutter 302.

[0087] The upper surface of the guide nozzle 104 is provided with a groove 1043, the groove 1043 extends along the width direction of the guide nozzle 104, and the slider is slidably disposed in the groove 1043.

[0088] The cutter 302 is located below the sliding block 301 and extends to the bottom surface of the tourniquet passage 1041 to cut the tourniquet.

[0089] Thus, when the tourniquet needs to be cut, the slider can be pushed to move along the length of the groove 1043 to drive the cutter 302 to move accordingly, thereby cutting the tourniquet.

[0090] Preferably, in one embodiment of the present invention, the bottom surface of the conveyor channel 1041 is provided with a retraction groove 1044, the retraction groove 1044 extends along the width direction of the guide nozzle 104, and the lower end of the cutter 302 extends into the retraction groove 1044.

[0091] Thus, by setting the retractable grass, the lower end of the cutter 302 can be lower than the tourniquet, thereby ensuring accurate and reliable cutting of the tourniquet during movement.

[0092] Preferably, in one embodiment of the present invention, the lower end of the cutter 302 is formed in an arc shape.

[0093] Thus, by setting the side of the cutter 302 to be arc-shaped, it is easier to cut into the tourniquet during cutting, and its passage is better, making the cutting smoother.

[0094] Preferably, in one embodiment of the present invention, one end of the slide groove 1043 is provided with a magnetic suction part 303 for adsorbing the cutter 302.

[0095] Thus, by providing the magnetic suction part 303 at one end of the slide groove 1043, the cutter 302 can be attracted to one side of the slide groove 1043, preventing it from sliding when not in use.

[0096] Preferably, in one embodiment of the present invention, the surface of the housing 10 is provided with an installation port, the installation port is connected to the accommodating cavity 101, and the installation port is provided with a detachable cover plate 105 for closing and opening the installation port.

[0097] Thus, when replacing or adding a tourniquet, the cover plate 105 can be opened, and the tourniquet can be added through the installation port, making the addition more convenient and quick. Advantageously, the connection between the cover plate 105 and the housing 10 can be a snap-fit ​​type or a threaded type.

[0098] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention.
