Description

Lumbar puncture indwelling device for cerebrospinal fluid

technical field

The utility model relates to a medical appliance, in particular to a device for indwelling cerebrospinal fluid during lumbar puncture.

Background technique

Lumbar puncture is one of the basic operating skills that doctors must master, especially for neurosurgeons, who must perform lumbar puncture for central nervous system inflammatory lesions, demyelinating diseases, brain tumors, and subarachnoid hemorrhage. Most of the currently used lumbar puncture bags are assembled and configured by the hospital supply room. In addition to the commonly used lumbar puncture needles, pressure measuring tubes, sterile gauze, etc., it generally includes about three sterile test tubes for the cultivation of pathogenic bacteria in the indwelling cerebrospinal fluid. The rest of the cerebrospinal fluid specimens that do not need to be sterile are taken by the doctor according to the needs of the disease, and the appropriate drying tube is placed in the indwelling. Generally, the drying tube is placed on the test tube rack during the lumbar puncture operation, and the test tube rack is placed next to the lumbar puncture bag. The doctor takes the dry tube to collect the cerebrospinal fluid during the operation.

At present, the clinical work is heavy, and one doctor has to manage many patients. Most of the time, only one doctor manages the lumbar puncture operation. Moreover, neurology departments generally retain more than 5 tubes of cerebrospinal fluid. Since the lumbar puncture is an aseptic operation, when the doctor collects the cerebrospinal fluid after the puncture, he must free a sterile gloved hand (usually the right hand) to take an ordinary dry tube to receive the cerebrospinal fluid, and then use another non-contaminated hand to collect the cerebrospinal fluid. The hand (usually the left hand) inserts the puncture needle core back into the puncture needle, then puts the drying tube back into the test tube rack, then takes the drying tube with the right hand, pulls out the needle core with the left hand, and can receive two tubes of cerebrospinal fluid at a time. Repeat this until the collection of cerebrospinal fluid samples is completed. Even if it is operated by two people, it is necessary to repeatedly insert and puncture the needle core during the connection process.

First of all, this process does not meet the requirements for aseptic operation of lumbar puncture, causing contamination of gloves, and the puncture needle and puncture site can no longer be touched. If the distinction between sterile hands and sterile hands is not strict or careless, the chance of infection after puncture may be greatly increased. , severe cases may cause iatrogenic meningitis/encephalitis. Secondly, repeated insertion and insertion of the puncture needle not only increases the chance of infection, but also easily causes puncture complications, such as foreign bodies and disinfectants brought into the sheath, implanted epidermoid tumors and nerve roots brought out, etc. Finally, keeping the cerebrospinal fluid for too long will bring discomfort to the patient, especially for those who cannot maintain the lumbar puncture position for a long time due to some reasons, causing iatrogenic pain.

Therefore, there is an urgent need for a special lumbar puncture indwelling cerebrospinal fluid device that meets the aseptic operation requirements of lumbar puncture, avoids secondary pollution, and reduces the work intensity of doctors performing lumbar puncture.

Utility model content

The purpose of the utility model is to provide a special lumbar puncture indwelling cerebrospinal fluid device that meets the requirements of lumbar puncture aseptic operation, avoids secondary pollution, and reduces the work intensity of doctors performing lumbar puncture.

The utility model provides a lumbar puncture indwelling device for cerebrospinal fluid, which is composed of a foldable test tube rack and at least one test tube.

There are ten test tube holes distributed on the test tube hole plate, which are divided into two rows, five in each row.

The diameter of the test tube hole matches the diameter of the test tube, so as to prevent the test tube from shaking in all directions when it is placed on the test tube rack.

The four uprights can be folded through the folding points of the uprights. After being folded, the entire test tube rack is basically on a plane, which is convenient for transportation and storage, and saves space. When in use, the upright column and the base are in a vertical state through the folding point of the upright column, so as to keep the balance of the whole test tube rack.

The base is connected into a rectangular structure by four fixing rods.

The test tube, preferably, is smaller than common blood-drawing test tubes, and its capacity is about 2/3 of that of common test tubes, which conforms to the characteristic that the volume of cerebrospinal fluid is not large. When the doctor operates with one hand, the test tube can be opened or covered, and the test tube can be sealed by the test tube cover switch point on the test tube cover.

In the utility model, a foldable test tube rack and a plurality of test tubes can be selected for clinical use according to needs. Preferably, it consists of a foldable test tube rack and two test tubes, and the two test tubes are sealed with sterile plastic bags.

The utility model can be packaged and placed in the waist-piercing bag before clinical use, and the weight and size of the waist-piercing bag will not be increased due to its small volume. It can also be sealed in a sterile plastic bag after disinfection, and placed separately, and the doctor can take it according to the specific requirements of each lumbar puncture. The indwelling test tubes can be sealed in groups of two to avoid waste after being unpacked once.

The utility model is designed according to the problems existing in the actual operation process of clinical lumbar puncture, and has compact structure, reasonable design, complete functions and convenient use. The entire lumbar puncture process can be completed by one doctor, which effectively saves manpower, and all are aseptic operations, avoiding the possibility of iatrogenic contamination.
