Description

A device for drainage of cerebrospinal fluid in lumbar pool

technical field

The utility model relates to a drainage device, in particular to a control device for cerebrospinal fluid drainage in a lumbar pool, which belongs to the technical field of medical devices.

Background technique

At present, through the continuous drainage of cerebrospinal fluid in the lumbar pool, the medical staff can control the intracranial pressure within the normal range, reduce the stimulation of bloody cerebrospinal fluid to the brain and meninges, promote the circulation and absorption of cerebrospinal fluid, relieve cerebral vasospasm, and improve cerebral insufficiency. Blood status, reducing the incidence of cerebral edema and cerebral infarction. However, if the drainage speed of the lumbar pool is too fast, it will cause intracranial depression, which will cause brain herniation; if the drainage is too slow, the drainage effect will not be achieved and may even cause tube blockage, so the drainage of the lumbar pool must be controlled at a suitable uniform speed for 24 hours . However, due to differences in the intracranial pressure of patients in clinical practice, the height of the head of the bed is not always the same. As a result, it is difficult to maintain a constant speed for a long time by using conventional drainage devices for lumbar cistern drainage.

Utility model content

The technical problem to be solved by this utility model is to propose a cerebrospinal fluid drainage device for the lumbar pool in view of the above shortcomings of the prior art, which has a simple structure and is easy to use. The control of the drainage speed by the peristaltic pump can greatly reduce the work of the nursing staff. quantity.

In order to solve the above technical problems, the utility model provides a cerebrospinal fluid drainage device for the lumbar pool, including a drainage bag, a peristaltic pump, a drainage thong and a Murphy's dropper; one end of the Murphy's dropper is connected to the The entrance of the lumbar pool is connected, and the other end of the Murphy's dropper is connected with a drainage thong, and the drainage thong passes through the turntable of the peristaltic pump, and is squeezed by the roller outside the turntable of the peristaltic pump, and the drainage thong The other end of the strip is connected to the drainage bag through the outlet port.

The technical solution further defined by the utility model is: the aforementioned device for cerebrospinal fluid drainage in the lumbar pool, the structure of the inlet section interface and the outlet port interface are the same, the interface includes an external thread mouth end and an internal thread seat end, and the external thread The mouth end is screwed on the inner thread of the inner thread seat end, and the mouth end of the outer thread and the inner thread seat end are provided with a hose insertion column, which is inserted and fixed with the drainage tube through the hose insertion column; An anti-slip groove is provided on the pipe insertion post.

Further, in the aforementioned cerebrospinal fluid drainage device for lumbar pool, the turntable of the peristaltic pump is evenly provided with three rotating rods, and a roller is provided at the end of each rotating rod.

The beneficial effects of the utility model are: the utility model has a novel structure, drives the drainage thong through the uniform rotation of the peristaltic pump to control the drainage speed in the drainage tube, makes the drainage process more intelligent and uniform, and effectively prevents the patient from being bedridden. The change of flow rate caused by the different angles is more convenient for medical staff to monitor the drainage process in real time.

detailed description

The utility model is described in further detail below:

Example 1

A kind of cerebrospinal fluid drainage device for lumbar cistern provided by this embodiment, the structure is shown in Figure 1 and Figure 2, comprises drainage bag 1, peristaltic pump 6, drainage thong 3 and Murphy's dropper 7; Murphy's dropper One end of 7 is connected to the entrance 9 of the lumbar pool through the inlet section interface 8, and the other end of the Murphy's dropper 7 is connected to the drainage thong 3, and the drainage thong 3 passes through the turntable of the peristaltic pump 6 and is squeezed by the rollers on the outside of the 6 turntable of the peristaltic pump. The other end of the drainage thong 3 is connected to the drainage bag through the outlet interface 2, and three rotating rods are evenly arranged on the rotating disk of the peristaltic pump 6, and a roller 4 is provided at the end of each rotating rod. The structure of the inlet section interface 8 of this embodiment is the same as that of the outlet port interface 2. The interface includes an external thread mouth end and an internal thread seat end, and the external thread mouth end is screwed on the internal thread of the internal thread seat end, and the external thread mouth end and The socket end of the internal thread is provided with a hose insertion column, and the hose insertion column and the drainage tube are inserted and fixed, and an anti-slip groove is provided on the hose insertion column.

When this embodiment is in use, in order to achieve a uniform speed effect, the DC motor in the peristaltic pump is used to drive the turntable to rotate at a constant speed, thereby driving the rollers to roll, so that a certain part of the drainage pipeline filled with liquid is squeezed, resulting in peristalsis, and then pushing the liquid to the Front flow; since the speed of the peristaltic pump is controllable, adjust the rotation speed of the turntable according to the actual situation of the patient, and maintain a constant and uniform speed, so as to achieve the effect of controlling the drainage speed.

The above embodiments are only to illustrate the technical ideas of the utility model, and cannot limit the protection scope of the utility model with this. Any changes made on the basis of the technical solutions according to the technical ideas proposed by the utility model all fall into the scope of the utility model. within the scope of the new protection.
