Detailed Description

The invention will be further explained with reference to the following figures and examples:

as shown in fig. 1 and 2, the utility model discloses a special drainage device for hepatobiliary department, which comprises a drainage main body 2, wherein a micro peristaltic pump 3, a pipeline 4 and a containing cavity 21 are arranged in the drainage main body 2, and a collecting bottle 6 or a collecting bag can be placed in the containing cavity 21; the top that holds chamber 21 is equipped with connector 5, the liquid outlet of miniature peristaltic pump 3 passes through pipeline 4 and connector 5 intercommunication, collecting flask 6 or collection bag accessible connector intercommunication pipeline 4.

Can set up the screw thread on the connector 5, collect bag or collecting bottle 6 like this all can be connected through the screw thread with the connector link, maintain better fixed simultaneously. In this scheme, the biggest improvement point is in the drainage tube. The drainage tube in the scheme is also arranged on the drainage main body 2.

The drainage tube comprises a tube body 12 and a front end tube head 11, the front end tube head 11 is small in size and large in size and is a rotary body, the lower end of the front end tube head 11 is coaxially, detachably and fixedly connected with the tube body 12, and the lower end of the tube body 12, far away from the front end tube head 11, is communicated with a liquid inlet of the micro peristaltic pump 3; a cylindrical cavity 11a communicated with the pipe body 12 is coaxially formed in the front end pipe head 11, a cleaning mechanism is arranged in the cylindrical cavity 11a, and the cleaning mechanism comprises a rotating rod 7, a driving impeller 9 and a scraping blade 8; the rotating rod 7 is coaxially and rotatably connected in the cylindrical cavity 11a, the driving impeller 9 is positioned at one side close to the pipe body 12 and coaxially fixed with the rotating rod 7, and the scraping blade 8 is positioned at one side far away from the pipe body 12 and fixed with the rotating rod 7; the lateral wall of the front-end tube head 11 is provided with a drainage hole 11b, the drainage hole 11b is communicated with the cylindrical cavity 11a, the edge of the scraping blade 8 is in sliding contact with the lateral wall of the cylindrical cavity 11a, and the scraping blade 8 is close to the orifice of the drainage hole 11b, so that the scraping blade 8 is utilized to scrape the joint of the cylindrical cavity 11a and the drainage hole 11 b.

The basic implementation of the scheme is far from the following:

when the medical drainage tube is used specifically, the front-end tube head 11 is inserted into the body of a patient, and bile or body fluid enters the cylindrical cavity 11a of the front-end tube body through the drainage hole 11 b. When the cleaning mechanism is not available, the junction of the drainage hole 11b and the cylindrical cavity 11a is easily covered by body fluid mucous membrane after a long time, namely, the drainage hole 11b is blocked. However, in this embodiment, under the action of the micro peristaltic pump 3, bile and body fluid enter the cylindrical cavity 11a through the drainage hole 11b, and enter the tube body 12 through the cylindrical cavity 11a at a certain pressure and flow rate. Therefore, bile, body fluid and partial air are when the initiative impeller 9 through wiper mechanism, initiative impeller 9 is by the bile, body fluid and air impact and then rotatory, initiative impeller 9 drives the bull stick 7 rotatory, the bull stick 7 drives the doctor-bar 8 rotatory again, rotatory doctor-bar 8 carries out the physics scratch to the handing-over department of drainage hole 11b and cylinder chamber 11a on the one hand, on the other hand can be to the bile of flowing through cylinder chamber 11a, body fluid and air are disturbed, destroy the formation of mucosa in the body fluid, and then prevent that the mucosa from attaching to in drainage hole 11b and the cylinder chamber 11a, make drainage hole 11b can not blockked up. As long as the micro peristaltic pump 3 works all the time, the mucosa can not be formed, so that the special drainage device in the scheme can work normally all the time, and the drainage hole 11b is not required to be dredged midway.

In order to make the impact action on the driving impeller 9 stronger, further: the lower end of the cylindrical cavity 11a is gradually reduced to form a tapered interface 11c with a large upper part and a small lower part, the driving impeller 9 is positioned in the tapered interface 11c, and the pipe body 12 is in threaded connection with the tapered interface 11 c. Through the conical interface 11c, bile, body fluid and air are more concentrated, the area acting on the driving impeller 9 is reduced, unit stress is increased, and the driving impeller 9 can better maintain an impacted state so as to be beneficial to preventing mucosa generation.

This scheme has still optimized pipe shaft 12, if: the tube body 12 comprises an upper tube section 12a and a lower tube section 12b which are coaxially connected, the upper tube section 12a and the lower tube section 12b are detachably fixed, the upper tube section 12a is connected with the front-end tube head 11, and the lower tube section 12b is connected with the drainage main body 2 and communicated with a liquid inlet of the micro peristaltic pump 3. Meanwhile, scales are engraved on the tube body 12. The division of the shaft 12 into a two-piece removable structure allows the shaft 12 to be lengthened or shortened as needed during use, primarily by increasing or decreasing the number of segments making up the shaft 12. Simultaneously, scales are carved on the can body, whether the tube body 12 shifts can be judged by reading scale values, and whether the front-end tube head 11 connected with the tube body 12 is consistently and stably placed in a patient body can be conveniently judged.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
