Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to a catheter perfusion strip dedicated for neurointerventional treatment. Background Art
[0002] Catheter perfusion in neurointerventional therapy involves using a medical catheter, guided by imaging equipment such as digital subtraction angiography (DSA), to continuously flush the catheter system through a perfusion fluid (typically saline) to prevent thrombotic or embolic complications. It is widely used in interventional treatments for a variety of conditions, including cerebrovascular diseases and neurological tumors.
[0003] Catheter perfusion is essential during neurointerventional diagnosis and treatment. Currently, ordinary infusion sets are connected to an extension tube for perfusion. The length and head end connection port may not match the length of surgical perfusion. Murphy-type droppers have no filtering function, and there are several perfusion routes during surgery, which is not convenient for distinguishing and using them during surgery. Therefore, it is necessary to propose a special catheter perfusion strip for neurointerventional treatment to solve the above problems. Utility Model Content
[0004] The purpose of the utility model is to provide a special catheter perfusion strip for neurointerventional treatment, which has the characteristics of being more convenient to use, reducing connections, filtering liquid, facilitating the management of intraoperative pipelines, and facilitating the distinction and replacement of perfusion paths.
[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a catheter perfusion strap for neurointerventional treatment, comprising a strap, one end of which is connected to a spiral connection valve, the other end of which is connected to a Murphy-type dropper, and an outer wall of the strap is provided with a speed regulator located on one side of the Murphy-type dropper;
[0006] The Murphy's dropper is provided with a filter screen inside, the speed regulator and the spiral connection valve are the same color, and the leather strip has a total length of 2.5 cm.
[0007] In order to ensure the perfusion pressure during surgery and improve safety, the catheter perfusion strap for neurointerventional treatment of the present invention is preferably a high-pressure resistant strap.
[0008] In order to connect the infusion bag, as the preferred catheter perfusion strap for neurointerventional treatment of the present invention, the other end of the Murphy-type dropper is connected to a connecting needle.
[0009] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0010] Firstly, the utility model can fully meet the length used in surgery through the leather strap with a total length of 2.5 meters, avoiding the situation where the secondary connection line is too long. There is no return air valve and it is fully enclosed, which is conducive to the pressurized bag to pressurize the liquid into the pipeline, avoiding leakage after pressurization, resulting in insufficient pressure. Moreover, by installing a filter screen inside the Murphy-type dropper, impurities and air that may exist in the liquid can be filtered to prevent impurities that may exist in the liquid from being directly pressurized and dripped into the catheter, which can better ensure the safety of the drip. Secondly, the spiral connecting valve and the speed regulator at the tail end are made into corresponding colors, which facilitates the management of the pipeline during surgery and facilitates the distinction and replacement of the perfusion path, thereby achieving more convenient use, reducing connections, and functions that can better meet the needs of interventional surgery, rather than the basic functions of ordinary infusion.

[0015] See also Figures 1 to 3 , a special catheter perfusion strip for neurointerventional treatment, comprising a strip 1, one end of the strip 1 being connected to a spiral connection valve 2, the other end of the strip 1 being connected to a Murphy-type dropper 4, and a speed regulator 3 being installed on one side of the Murphy-type dropper 4 on the outer wall of the strip 1;
[0016] A filter screen 401 is installed inside the Murphy-type dropper 4, the speed regulator 3 and the spiral connection valve 2 have the same color, and the entire length of the leather strip 1 is 2.5 cm.
[0017] In this embodiment, a 2.5-meter-long strap 1 can fully meet the length required for surgery, avoiding the occurrence of excessively long secondary connections. One end of the strap 1 is connected to the spiral connection valve 2, and the other end is connected to the Murphy's dropper 4. No return valve is required, and the strap is fully enclosed. This facilitates the pressurization bag to pressurize the liquid into the pipeline, preventing air leakage after pressurization, which may lead to insufficient pressure. A filter 401 is installed inside the Murphy's dropper 4 to filter out impurities and air that may be present in the liquid, preventing impurities in the liquid from being directly pressurized and dripped into the catheter, thereby ensuring the safety of the drip. A speed regulator 3 is installed on the outer wall of the strap 1 to facilitate the adjustment of the liquid drip rate. Secondly, the spiral connection valve 2 and the speed regulator 3 at the tail end are made of corresponding colors (for example, one of red, yellow, green, and blue to facilitate intraoperative differentiation). This facilitates intraoperative pipeline management and facilitates the distinction and replacement of perfusion paths, thereby achieving more convenient use, reducing connections, and functions that better meet the needs of interventional surgery, rather than the basic function of ordinary infusion.
[0018] As a technical optimization solution of the present invention, the leather strap 1 is a high-pressure resistant leather strap.
[0019] In this embodiment, the leather strap 1 is a high-pressure resistant leather strap, which can better ensure the perfusion pressure during surgery and improve safety.
[0020] As a technical optimization solution of the present invention, the other end of the Murphy-type dropper 4 is connected to a connecting needle 5.
[0021] In this embodiment, the connecting needle 5 can be used to connect to the infusion bag.
[0022] Working Principle: First, the 2.5-meter-long strap 1 can fully meet the length required for surgery, avoiding the occurrence of excessively long secondary connection lines. The strap 1 is high-pressure resistant, which can better ensure the infusion pressure during surgery and improve safety. One end of the strap 1 is connected to the spiral connection valve 2 and the other end is connected to the Murphy-type dropper 4. No return valve is required, and the strap is fully enclosed. This facilitates the pressurization bag to pressurize the liquid into the pipeline, avoiding air leakage after pressurization, resulting in insufficient pressure. The connecting needle 5 is then connected to the infusion bag to complete normal infusion. The filter 401 installed inside the Murphy-type dropper 4 can filter out impurities and air that may be present in the liquid, preventing impurities in the liquid from being directly pressurized and dripped into the catheter, further ensuring the safety of the infusion. A speed regulator 3 is installed on the outer wall of the strap 1 to facilitate the adjustment of the liquid drip rate. Secondly, the spiral connection valve 2 and the speed regulator 3 at the tail end are made into corresponding colors (for example, one of red, yellow, green, and blue, to facilitate intraoperative differentiation). This facilitates intraoperative pipeline management and facilitates the distinction and replacement of the infusion path.
[0023] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
