Description

PICC pipe-through device

Technical Field

The utility model relates to the field of medical instruments, in particular to a PICC (peripherally inserted central catheter).

Background

PICC refers to central venous catheter placed through peripheral vein, and is a common chemotherapy drug infusion pipeline in hospitals. The blockage is a common problem of the PICC catheter because blood enters the PICC catheter and solidifies, which causes the catheter to be blocked and the liquid medicine to be conveyed smoothly.

The PICC catheter is blocked and then needs to be dredged, and at present, the hospital adopts two syringes for dredging; both syringes are in communication with the PICC catheter, one for aspiration to create a negative pressure in the PICC catheter and the other for aspiration into urokinase. When the tube is used, a pipeline connected with a syringe filled with urokinase is closed, and suction is carried out by a suction syringe, so that negative pressure is formed in the PICC catheter; then closing the pipeline connected with the suction injector, and opening the pipeline connected with the injector with urokinase, wherein the negative pressure in the PICC catheter sucks the urokinase and keeps the urokinase for a period of time, and the urokinase dissolves the coagulated blood clot to play a role of a through pipe. The above steps are performed a plurality of times until the catheter is dredged. The above-mentioned suction operation is laborious and in addition requires repeated times, which is cumbersome.

In order to reduce nursing work difficulty, PICC sippers beneficial to labor saving are appeared. For example, the patent of publication No. CN217854048U filed by the applicant discloses a PICC applicator. The PICC runner drives the syringe to suck through a screw tightening mode, so that much labor is saved. However, the suction operation still needs to be carried out for many times, and is still complicated; when the suction injector sucks to the maximum capacity, the suction injector is detached, the piston is pushed forwards and then is assembled again, and suction can be continued; the convenience of the through pipe is not obviously improved.

The specific structure of the connection joint 212 is preferably as shown in fig. 3, the connection joint 212 comprises a joint base plate 2121, an inner joint 2122, a sealing pad 2126 and an outer sleeve 2123, wherein the inner joint 2122 is arranged on the joint base plate 2121, the sealing pad 2126 is sleeved outside the inner joint 2122 and connected with the joint base plate 2121, a first one-way valve 2124 is arranged on the inner joint 2122, the outer sleeve 2123 is sleeved on the inner joint 2122 and connected with the inner joint 2122 in a threaded manner, a filtering membrane 2125 is arranged on the outer sleeve 2123, and the suction bottle 3 is connected with the outer sleeve 2123 in a threaded manner.

The function of the filter membrane 2125 is to avoid liquid droplets entering the connection joint 212 and the suction chamber 211, since the connection joint 212 and the suction chamber 211 are inconvenient to clean and sterilize, and it is necessary to keep them clean. The disposable tube is preferably replaced because the liquid spray tends to adhere to the filter membrane 2125. Based on the present utility model, an outer sleeve 2123 is provided to be fitted over the inner joint 2122 and screwed to the inner joint 2122, and a filtering membrane 2125 is provided to the outer sleeve 2123 in the sense of facilitating replacement of the filtering membrane. The outer sleeve 2123 is removed and the outer sleeve 2123 is discarded together with the filter membrane 2125. The new outer sleeve 2123 and filter membrane 2125 are then replaced for the next use.

The reason why the hinge hole 231 is a horizontally provided long hole is that the piston rod 23 can only move up and down, while the lever body 41 is swung, and if the hinge hole 231 is not a long hole, movement interference occurs.

Preferably, as shown in fig. 4, the lever body 41 is composed of two parts connected to each other, and the two parts can be detached. The two parts may be threaded. The meaning of this arrangement is that the rear part of the lever body 41 can be detached when not in use, so that the PICC pipe fitting is prevented from being excessively long, which results in inconvenient storage. In order to improve the tactile sensation, it is preferable that the tail end of the lever body 41 is fitted with a flexible sleeve 43.
