However, for painless endoscopic patients, high-concentration liquid medicine needs to be injected into veins for a short time, generally within one hour, but the existing conventional indwelling needle is applied to the treatment of painless patients, and generally has the following problems: firstly, the existing indwelling needle is usually provided with a heparin cap, and the painless endoscope needs a fast flow rate and a short time, so that the heparin cap is generally directly discarded during treatment of a painless endoscope patient, and waste is caused; secondly, the existing indwelling needle is usually provided with only one medicine injection port, so that the operation is very inconvenient when various medicines are required to be injected simultaneously, the infusion set switch and the indwelling needle clamp are usually required to be closed firstly, the indwelling needle and the infusion set connector are disconnected, then medicine is added, the medicine is temporarily and repeatedly added, and the switch is inconvenient.
Disclosure of Invention
Aiming at the problems existing in the prior art, the utility model aims to provide the special indwelling needle for the endoscope, which can save cost and is convenient for repeated drug adding.
The utility model is realized by the following technical scheme:
the utility model provides a special needle of keeping somewhere of scope, includes needle subassembly, annotates liquid subassembly and infusion and connects the subassembly, annotate liquid subassembly and link to each other with the needle subassembly through coupling hose and infusion and connect the subassembly, the needle subassembly includes the sleeve pipe and sets up at the intraductal pjncture needle of cover, sheathed tube other end fixedly connected with pipe seat, annotate liquid subassembly including the three-way pipe and set up the tee bend switch that uses with the three-way pipe cooperation on the three-way pipe, a branch pipe and coupling hose of three-way pipe are connected, are provided with the protection cap on two other branch pipes of three-way pipe respectively.
Further, the three-way switch is arranged on the three-way pipe through screwing and used for controlling the opening and closing of the three-way pipe.
Further, the catheter seat is provided with a needle core protecting wing and a plug.
Further, the infusion connector assembly comprises an infusion connector and a conical connecting pipe, and the infusion connector is connected with the three-way pipe and the conical connecting pipe is connected with the catheter seat through connecting hoses.
Further, a clip is arranged on the connecting hose between the conical connecting pipe and the catheter seat.
Further, the puncture needle is a needle core with the size of 22G or more.
The utility model can realize the treatment of endoscope patients by simply improving the existing indwelling needle, saves cost, is convenient to switch in time, is convenient for simultaneously injecting various medicines, and is not only used for painless endoscopes, but also used for painless minor operations.
Drawings
FIG. 1 is a schematic diagram of the overall structure of the present utility model;
FIG. 2 is a schematic diagram of the mounting structure of the tee and the three-way switch;
in the figure, a 1-connecting hose, a 2-sleeve, a 3-puncture needle, a 4-catheter seat, a 5-three-way pipe, a 6-three-way switch, a 7-protective cap, an 8-needle core protective wing, a 9-plug, a 10-transfusion joint, an 11-conical connecting pipe and a 12-clip.
Detailed Description
The utility model is described in further detail below in conjunction with the drawings of the specification to provide a better understanding of the present technical solution.
As shown in fig. 1-2, the special indwelling needle for endoscope comprises a needle head assembly, a liquid injection assembly and an infusion connector assembly, wherein the liquid injection assembly is connected with the needle head assembly through a connecting hose 1 and the infusion connector assembly, the needle head assembly comprises a sleeve 2 and a puncture needle 3 arranged in the sleeve 2, the puncture needle 3 adopts a needle core with the size of 22G or more, the other end of the sleeve 2 is fixedly connected with a catheter seat 4, and the catheter seat 4 is provided with a needle core protecting wing 8 and a plug 9 which are convenient for medical staff to operate. The infusion joint assembly comprises an infusion joint 10 and a conical connecting pipe 11, the infusion joint 10 is connected with the three-way pipe 5 and the conical connecting pipe 11 is connected with the catheter seat 4 through a connecting hose 1, and a clamp 12 is arranged on the connecting hose 1 between the conical connecting pipe 11 and the catheter seat 4.
With continued reference to fig. 1-2, the liquid injection assembly includes a three-way pipe 5 and a three-way switch 6 disposed on the three-way pipe 5 and used in cooperation with the three-way pipe 5, specifically, the three-way switch 6 is disposed on the three-way pipe 5 by screwing, for controlling the opening and closing of the three-way pipe 5, the specific screwing structure can adopt the existing conventional structure, one branch pipe of the three-way pipe 5 is connected with the connecting hose 1, and the other two branch pipes of the three-way pipe are respectively provided with a protective cap 7.
