Description

Intracranial ommaya bag percutaneous puncture drainage device

Technical Field

The utility model belongs to the technical field of medical instrument, concretely relates to intracranial ommaya bag percutaneous puncture drainage device.

Background

The treatment of patients with ventricular diseases is usually achieved by inserting Ommaya sac to perform various punctures and continuous drainage. In the current clinical work, a syringe or a puncture needle with a smaller caliber is usually used for puncturing the Ommaya sac through the scalp, and liquid is drawn once or drained continuously. The external fixation of the puncture needle in the continuous drainage operation is a very delicate link, the puncture needle is not firmly fixed and easily falls off, the local scalp is injured, the infection risk is increased, and the puncture needle is easily fixed by pressurization and is easy to have unsmooth drainage.

Because the brain of a human is placed in the catheter end of the Ommaya sac, cerebrospinal fluid or other liquids are drained to the sac through the catheter, the cerebrospinal fluid or other liquids are a closed environment communicated with the inside of a human body, and the scalp outside the sac is separated from the closed environment, the important link in the whole medical activity is how to protect the health and the integrity of the scalp. At present, the fine needle puncture drainage adopted clinically cannot be well fixed and is easy to fall off, the secondary puncture after falling off is an important factor for damaging the scalp, the fine needle puncture drainage is easy to shift in the fixed drainage, once the fine needle puncture drainage shifts, an angle is formed between a puncture needle and the scalp, and the scalp can be locally necrotized by directly pressing the local scalp, a defense mechanism is lost, and even direct pollution is caused. There is currently no good solution.

Disclosure of Invention

The utility model relates to an intracranial ommaya sac percutaneous puncture drainage device, which overcomes the defects of the prior art.

The technical proposal of the utility model is that the intracranial ommaya sac percutaneous puncture drainage device comprises a puncture needle, a needle holder, a drainage tube and a three-way joint; the puncture needle is T-shaped, the lower part of the puncture needle is a needle head, and the upper part of the puncture needle is an arc needle handle; the needle holder is of a hemispherical cavity structure, and a groove matched with the arc needle handle is formed in the inner surface of the hemispherical cavity structure; the arc needle handle is embedded into the groove and is fixedly sealed through a vulcanization process, and the needle head is kept in a vertical state and is positioned on the central line of the hemispherical cavity structure; the needle head and the right half part of the arc needle handle are provided with mutually communicated channels, and the right end of the arc needle handle extends out of the outer surface of the hemispherical cavity structure; one end of the drainage tube is connected with the right end of the arc needle handle, and the other end of the drainage tube is connected with the three-way joint.

The puncture needle is made of stainless steel materials, the needle holder is made of hard rubber materials, the drainage tube is a medical hose, and the three-way connector is made of medical plastics.

And the middle part of the drainage tube is connected in series with a flowmeter.

Compared with the prior art, the utility model advantage and effect that have:

1. the utility model discloses it is fixed convenient, and the pjncture needle is difficult for shifting, drops, has avoided puncturing repeatedly and the local scalp necrosis that the pjncture needle oppression leads to, is unlikely to again the pjncture needle direct exposure outside, has reduced the infection incidence, has the tee bend interface that can the external drainage device of lug connection moreover, also can carry out operations such as drawing liquid chemical examination or injection by the tee bend interface simultaneously.

2. The utility model discloses a flowmeter direct readout flow numerical value avoids the drainage volume too much or too little.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings 1 and 2.

An intracranial ommaya sac percutaneous puncture drainage device comprises a puncture needle 1, a needle holder 2, a drainage tube 3 and a three-way joint 4; the puncture needle 1 is T-shaped, the lower part is a needle head 1-1, and the upper part is an arc needle handle 1-2; the needle holder 2 is of a hemispherical cavity structure, and the inner surface of the hemispherical cavity structure is provided with a groove 2-1 matched with the arc needle handle 1-2; the arc needle handle 1-2 is embedded into the groove 2-1 and is fixedly sealed through a vulcanization process, and the needle head 1-1 is kept in a vertical state and is positioned on the central line of the hemispherical cavity structure; the needle head 1-1 and the right half part of the arc needle handle 1-2 are provided with mutually communicated channels 1-3, and the right end of the arc needle handle 1-2 extends out of the outer surface of the hemispherical cavity structure; one end of the drainage tube 3 is connected with the right end of the arc needle handle 1-2, and the other end is connected with the three-way joint 4.

The puncture needle 1 is made of stainless steel materials and can be designed into different models according to the thickness of the scalp of a patient and the actual use requirements, the needle holder 2 is made of hard rubber materials, the drainage tube 3 is a medical hose, and the three-way joint 4 is made of medical plastic materials. The middle part of the drainage tube 3 is connected in series with a flowmeter 5.

When the multifunctional needle holder is used, after a medical worker holds the needle holder 2 to complete puncture, the needle holder 2 with the hemispherical cavity structure can cover the scalp at the Ommaya sac placing part, then the periphery of the needle holder 2 with the hemispherical cavity structure is fixed with the scalp at the periphery of the Ommaya sac placing part by using medical adhesive tapes, the needle holder 2 with the hemispherical cavity structure is ensured to firmly cover the scalp at the Ommaya sac placing part and is not easy to shift and fall off, the puncture needle is ensured to be fixed without displacement through the scalp and the puncture point of the Ommaya sac, then the three-way joint 4 is connected with an external drainage device to continuously drain liquid through the drainage tube 3, the numerical value is directly read through the flowmeter 5, and the excessive or insufficient drainage quantity is avoided. If the medicine treatment is needed, the medicine can be directly injected through the three-way joint 4.

The utility model discloses a hand-held needle holds in palm and accomplishes the puncture back needle support and cover naturally on the scalp that needs the protection, the rethread rubberized fabric is fixed, ensure that the pjncture needle is fixed firm not to produce the displacement through the puncture point of scalp and Ommaya bag, better solution last among the drainage operation to the protection of scalp, the fixed poor stability of pjncture needle, local pollution prevention is unsafe and drainage inconvenience scheduling problem, overcome the more risk factor that the puncture drainage exists, the patient has been protected, treatment quality has been guaranteed. The utility model discloses can realize that percutaneous puncture Ommaya bag carries out single drawing of liquid or lasts the drainage clinically, have higher stability and security.
