Embodiment Construction

[0033] The present invention will be further explained and described below in conjunction with accompanying drawing and specific embodiment

[0034] Such as figure 1 As shown, a comprehensive lumbar puncture and drainage system includes a puncture needle core 1, an outer cannula 2, and a drainage tube 3 connected to the tail end of the outer cannula. The wall gradually becomes thinner and gathers toward the middle; the curved part at the front end and the body part of the outer casing are made of polyurethane material.

[0035] The inner diameter of the outer casing is consistent with the outer diameter of the puncture needle, and the length matches.

[0036] The tail end of the outer casing 2 is connected with a casing cap 7 .

[0037] Such as figure 2 with image 3 As shown, a cap hole 9 is provided in the middle of the top of the casing cap 7, and a silicone pad 10 is provided inside the casing cap, and the silicone pad is thickened at the hole of the casing cap until ...

Abstract

The invention relates to a medical device, and discloses a puncture of lumbar cistern drainage integrated solution system, which comprises a puncture needle core (1), a protection casing (2) and a rubber drainage tube (3) connected to the end of the protection casing. The frontal protection casing (2) is arc-shaped. The frontal protection casing wall is getting thinner and gathering in the middle.The frontal flexion and the protection casing body are prepared with polyurethane material. When using this system, the puncture drainage system of the proper length is selected, the puncture needleis inserted into the sleeve, and the sleeve tip is kept straight under the action of the cemented carbide core to facilitate puncture. After the puncture is successful, the needle core is pulled out and tube is completed at the same time, and the frontal portion is restored to a prefabricated curved shape to avoid the tip irritation and damaging spinal cord tissue. Compared with the common puncture tube drainage system, the system can simplify the clinical operation flow, shorten the operation time, reduce the accidental tube drawing event, reduce the medical cost burden of the patient and relieve the pain of the patient.

Description

technical field [0001] The invention relates to a medical device, in particular to a comprehensive solution system for lumbar pool puncture and drainage. Background technique [0002] In clinical work, in the treatment of intracranial infection, subarachnoid hemorrhage, cerebral hemorrhage and other diseases, it is often necessary to use lumbar cistern catheter drainage, that is, through puncture, a medical tube is placed in the lumbar cistern to drain the lumbar cistern. The bloody cerebrospinal fluid or bloody cerebrospinal fluid is drained out of the body to reduce intracranial pressure, reduce the stimulation of toxins or blood decomposition products to the nervous system, and achieve the purpose of treating or assisting the treatment of diseases. In general, there are currently two clinical catheter drainage methods: [0003] 1. Puncture and drainage method: the puncture and drainage kit used in this method mainly includes a metal puncture needle with a needle core and...
