Description

Technical Field

[0001] The utility model relates to the field of medical technology, in particular to a side-lying fixing device for lumbar puncture of a patient. Background Art

[0002] A lumbar puncture is a medical procedure used to obtain a sample of spinal fluid or to inject medication into the spine and spinal cavity. It is usually done in the lower back with the patient lying in a flexed position on one side. The patient is usually asked to lie flat on one side, usually the left or right side, with their knees hugged and their head in line with their chest. This position helps open the space between the lumbar spine and makes it easier for the doctor to locate and perform the puncture.

[0003] However, in the prior art, since some patients may feel uncomfortable or accidentally move or twist their legs during the puncture process, causing the puncture point to shift, the doctor may lose the accurate perception of the puncture position and need to readjust the posture and reposition. The doctor cannot accurately puncture the target area, which increases the difficulty of the puncture process and the risk of complications, affecting the puncture accuracy and easily leading to an unsuccessful puncture. Utility Model Content

[0004] The purpose of the utility model is to solve the technical problems in the prior art that during the puncture process, some patients may feel uncomfortable or accidentally move or twist their legs, causing the puncture point to shift, and the doctor may lose the accurate perception of the puncture position and need to readjust the posture and reposition. The doctor cannot accurately puncture the target area, which increases the difficulty of the puncture process and the risk of complications, affecting the puncture accuracy and easily leading to unsuccessful puncture. A side-lying fixation device for lumbar puncture of patients is proposed.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a patient lumbar puncture side-lying fixation device, comprising a sampling bed, a support block is arranged on the outer surface of the sampling bed, a side surface of the support block is rotatably connected to a screw rod via a bearing, a nut is threadedly connected to the outer surface of the screw rod, a sleeve is fixedly connected to one side surface of the nut, one end of the sleeve is fixedly connected to a support plate, a telescopic rod is fixedly connected to the outer surface of the support plate and the outer surface of the support block, and a support pad is fixedly connected to one side surface of the support plate.

[0006] Furthermore, a slide rail is fixedly connected to the outer surface of the sampling bed, a linear bearing is sleeved on the outer surface of the slide rail, and an upper surface of the linear bearing is fixedly connected to the lower surface of the support block.

[0007] Furthermore, the outer surface of the support block is fixedly connected to a mounting plate, a sliding rod passes through the lower surface of the mounting plate, the lower end of the sliding rod is fixedly connected to a pressure plate, the upper surface of the pressure plate is fixedly connected to a spring, one end of the spring is fixedly connected to the lower surface of the mounting plate, and the upper end of the sliding rod is fixedly connected to a pull ring.

[0008] Furthermore, a rubber pad is fixedly connected to the lower surface of the pressing plate, and a plurality of V-shaped grooves are equidistantly formed on the lower surface of the rubber pad.

[0009] Furthermore, a support ring is embedded inside the sleeve, the inner wall surface of the support ring is sleeved on the outer surface of the screw rod near one end, the outer surface of the support ring is fitted to the inner wall surface of the sleeve, and three grooves are equidistantly formed on one side surface of the support ring.

[0010] Furthermore, one end of the screw rod is fixedly connected to a rotating member.

[0011] Compared with the prior art, the advantages and positive effects of the utility model are:

[0012] 1. In the utility model, the sleeve drives the support plate and the support pad to move synchronously with the nut, so that the support pad is close to the patient's leg bend until it fits with the patient's leg bend, provides support for the patient's leg, and pushes the patient's knee to continuously approach the patient's chest to form a moderate bending angle, so that the patient's leg is in a state of hugging the knee, better exposing the intervertebral space, the support plate and the support pad support the patient's leg, fix the angle between the leg and the patient's body, and ensure that during the puncture process, the patient will not move or twist the leg due to discomfort or accident, thereby maintaining the stability of the puncture point.

[0013] 2. In the utility model, by pulling the pull ring, the slide rod drives the pressure plate and the rubber pad to move up, the rubber pad is separated from the upper surface of the slide rail, and then the support block is pushed, so that the support block moves along the slide rail under the action of the linear bearing, so that the support plate and the support pad move to the patient's knee bend, without the patient adjusting the posture, to quickly provide support for the patient's legs. After the adjustment is completed, the pull ring is released, and the spring pushes the pressure plate and the rubber pad to reset, and the rubber pad fits the upper surface of the slide rail. Multiple V-grooves increase the friction between the rubber pad and the slide rail to avoid displacement of the support plate and the support pad during use. The support ring is embedded in the interior of the sleeve. When the sleeve moves, the support ring provides supporting force for the sleeve to avoid shaking of the sleeve. The three grooves reduce the contact area between the support ring and the inner wall surface of the sleeve, thereby reducing friction. The lead screw is rotated by the rotating part to increase the force arm, save manpower, and provide a good user experience. BRIEF DESCRIPTION OF THE DRAWINGS
