Description

Technical Field

[0001] The utility model mainly relates to the technical field of medical devices, and specifically relates to a medical lateral lying fixator. Background Technique

[0002] Medical devices refer to instruments, equipment, appliances, in vitro diagnostic reagents and calibrators, materials and other similar or related items that are directly or indirectly used on the human body. Their effects are mainly obtained through physical means, and their purposes are the diagnosis, prevention, monitoring, treatment or alleviation of diseases, the diagnosis, monitoring, treatment, alleviation or functional compensation of injuries, the inspection, substitution, regulation or support of physiological structures or physiological processes, the support or maintenance of life, and the provision of information for medical or diagnostic purposes by examining samples from the human body. Among them, the lateral lying fixator is a common medical device.

[0003] The lateral lying fixator is used to place the body position of patients who receive lumbar anesthesia in the lateral lying position. Currently, the existing lateral lying fixators generally provide a thrust to the patient's back and waist to prevent the patient from lying down when receiving anesthesia and injecting anesthesia from the back. Scientifically speaking, it should be injecting anesthesia "intraspinal canal". Its operating principle is to inject anesthetic drugs into the subarachnoid space or epidural space of the spinal canal, and the spinal nerve roots are blocked so that the corresponding areas innervated by the nerve roots produce anesthetic effects.

[0004] In actual work, before anesthesia, anesthesiologists will guide patients to curl up their bodies, try to bend the torso ventrally as much as possible, and make the spine bend backward as much as possible. Looking from the side, it looks like the shape of a "shrimp". This can widen the distance between the spinous processes (intervertebral spaces), making it easier for the puncture needle to enter, so as to shorten the puncture time and improve the puncture success rate. However, this posture may feel uncomfortable for some patients, such as obese, pregnant and elderly patients, etc., and they may even be unwilling to cooperate and will subconsciously stretch out their legs from the curled state, resulting in inaccurate injection gap positions of the drug, affecting the anesthesia effect, and even unexpected situations may occur. Content of the Utility Model

[0005] The technical solution of the utility model aims at the technical problem that the existing technical solutions are too single, and provides a solution significantly different from the existing technology. Specifically, the utility model mainly provides a medical lateral lying fixator to solve the technical problem that during the process of injecting anesthetic into the patient's back, the patient may subconsciously stretch out their legs from the curled state, resulting in inaccurate injection gap positions of the drug and affecting the anesthesia effect as mentioned in the above background technique.

[0006] The technical solution adopted by the utility model to solve the above technical problems is as follows:

[0007] A medical lateral fixation device includes a bed frame body, on which a lower body positioning mechanism is provided. The lower body positioning mechanism includes two parallel slide bars mounted on the bed frame body. Each slide bar is provided with a sliding block. An intermediate shaft and a positioning shaft are respectively provided on the two sliding blocks. A limiting roller is rotatably connected to the intermediate shaft, a support plate is sleeved on the positioning shaft, and a gland is provided at the upper end of the positioning shaft.

[0008] Further, a cylindrical handle passes through the circular hole on the gland.

[0009] Further, the lower end of the intermediate shaft is threadedly connected to the sliding block.

[0010] Further, two cylinders are provided on the lower side of the bed frame body. The output end of each cylinder is provided with a push rod. The front end of each push rod is provided with a connecting plate, and the connecting plate is connected to the corresponding sliding block.

[0011] Further, the positioning shaft includes a cylindrical part, an upper threaded head and a lower threaded head. The lower threaded head is threadedly connected to the corresponding sliding block, and the upper threaded head is threadedly connected to the gland.

[0012] Further, a retaining strip is provided at the side edge position of the bed frame body, and a mattress body is provided between the retaining strips. The mattress body includes a first mattress, a second mattress, a third mattress and a fourth mattress.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] By setting the bed frame body, the mattress body, the slide bars, the sliding blocks, the intermediate shaft, the positioning shaft, the limiting roller, the support plate, the cylinders, the push rods and the connecting plates, the present utility model realizes that during the process of injecting anesthesia into the patient's back spinal canal, the support plate supports the patient's buttocks position, and the limiting roller restricts the lower side of the patient's thighs, so that the patient's torso bends ventrally, and it looks like a "shrimp" shape from the side. Thus, the distance between the spinous processes can be enlarged, which is beneficial for the puncture needle, so as to shorten the puncture time and improve the puncture success rate, effectively avoiding the situation that obese, pregnant and elderly patients and others stretch their legs from the curled state unconsciously due to discomfort, resulting in inaccurate injection gap position and affecting the anesthesia effect.
