Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a lumbar puncture auxiliary device. Background Art

[0002] Lumbar puncture is one of the commonly used clinical examination methods and is of great value for the diagnosis and treatment of neurological diseases. The general operation process is that the patient lies on his side on a hard bed with his back perpendicular to the bed surface, his head forward and his chest flexed, his hands holding his knees close to his abdomen, and then the puncture point is determined and the needle is inserted to obtain cerebrospinal fluid. Generally, there are two problems in this process. One is that it is difficult for the patient to maintain a stable position. For example, the pain during acupuncture may cause the patient to change his position reflexively, or he may gradually become unable to maintain the position due to fatigue after maintaining a position for a long time. If the position changes, the puncture needle may be offset when entering and exiting the needle, which may endanger the patient's safety. Another problem is the determination of the puncture point. The puncture point is generally the intersection of the line connecting the posterior superior iliac spine and the posterior midline, that is, the space between the 3rd and 4th lumbar spinous processes, and sometimes it can be performed in the space between the upper or lower lumbar vertebrae. Different patients have different body shapes. For example, the puncture point of thin patients is obvious and easy to identify on the spine, while the puncture point of obese patients is difficult to identify. This will result in the need to feel the spine to determine the puncture point each time, which will greatly reduce the efficiency of lumbar puncture.

[0003] In response to the above problems, the existing technology includes a variety of auxiliary devices, including the multifunctional lumbar puncture position fixator disclosed in patent number CN218338660U, which can assist in fixing the patient's back to keep it perpendicular to the bed surface as much as possible, and is equipped with a heating plate to keep the patient warm in cold weather; the pediatric lumbar puncture positioning and tightening assembly disclosed in patent number CN217525393U binds the patient's shoulders and thighs together to keep them in a suitable puncture position as much as possible. Most of the existing technologies focus on assisting patients to maintain their position, but cannot simultaneously highlight the patient's spine to assist doctors in finding the puncture point. Summary of the invention

[0004] In order to solve the above problems existing in the prior art, the present invention is intended to provide a lumbar puncture assisting device, which is intended to solve the technical problem that the prior art cannot assist the patient to maintain the body position while assisting the doctor to determine the puncture point.

[0005] A lumbar puncture assisting device comprises a stretching assembly, wherein both ends of the stretching assembly are provided with surrounding fixing assemblies, wherein the stretching assembly comprises two detachably connected stretching parts, and a gap is provided between the two stretching parts for facilitating the insertion of a puncture needle; the fixing assembly is used to assist a patient in maintaining a suitable body position, and at the same time, the stretching part is used to stretch the skin on both sides of the patient's spine so that the spine is as prominent as possible, assisting a doctor in inserting the puncture needle through the gap, thereby ensuring the accuracy of the lumbar puncture as much as possible.

[0006] Preferably, a positioning groove is provided on the side of the stretching part close to the body, and the positioning groove is provided at the edge of the stretching part away from the fixing component, and medical release paper is provided in the positioning groove; the medical release paper is used to closely adhere to the skin on both sides of the patient's spine, so that the stretching part can completely stretch the skin on both sides of the spine.

[0007] Preferably, the upper and lower ends of the stretching part are connected by a buckle belt with adjustable length; the two stretching parts are respectively arranged on both sides of the patient's spine and then fixed with the buckle belt.

[0008] Preferably, the upper fixing belt and the lower fixing belt are parallel to each other, and both ends of the upper fixing belt and the lower fixing belt are fixedly connected to the stretching part; the upper fixing belt is used to bind the patient's upper back and knees together, and the lower fixing belt is used to fix the patient's waist and the back of the thigh together, thereby assisting the patient to maintain a suitable body position.

[0009] Preferably, the upper fixing strap is detachably connected to an auxiliary fixing strap, both ends of the auxiliary fixing strap are detachably connected, and a fixing ring is provided on one side of the auxiliary fixing strap; the auxiliary fixing strap is fixed to the patient's calf near the knee, and then the upper fixing strap is passed through the fixing ring on the auxiliary fixing strap, so as to prevent the upper fixing strap from falling off from the knee when the patient moves carelessly.

[0010] Preferably, the upper fixing strap and the lower fixing strap are buckle straps with adjustable lengths, so as to accommodate patients of different body shapes and ensure the comfort of the patients while ensuring the stability of their posture as much as possible.

[0011] Preferably, the stretching portion is made of bendable PVC material, so that the stretching portion fits completely with the patient's back, ensuring that the stretching portion applies uniform pressure on the patient's back and ensuring the patient's comfort.

[0012] Preferably, the stretching portion is provided with scale lines, which are arranged on the back side of the positioning groove and are arranged opposite to the positioning groove; so that the doctor can understand the needle insertion position more accurately when inserting the puncture needle.

[0013] The beneficial effects of the present invention include: a fixing component and a stretching component are provided at the same time, and the skin on both sides of the patient's spine is slightly stretched while the patient's position is fixed, so that the patient's spine is more obvious, and the doctor can see the position of the spine more clearly and will not mistakenly insert the puncture needle into a place other than the spine, thereby fully ensuring the safety and accuracy of lumbar puncture.

[0014] In addition, the utility model has a simple structure and is easy to store; it is easy to use and more convenient for medical staff to operate; and the raw materials are simple and easy to obtain, the production cost is lower, and it is easier to promote and use.
