Detailed Description
The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.
By figure 1 to 6 and give, sleeve pipe 1 including the left and right directions, coaxial upside incomplete annular guide way 2 of having seted up on the sleeve pipe 1 outer wall, sleeve pipe 1 is run through to the left end of annular guide way 2, the right-hand member of annular guide way 2 runs through sleeve pipe 1 right side outer fringe face, sliding connection has the right-hand member to stretch out annular guide way 2's steel needle 3 in the annular guide way 2, the left end of steel needle 3 is tangent with sleeve pipe 1's upside for the inclined plane and its inclined plane of stretching out annular guide way 2, be equipped with a plurality of annular stoppers 4 of arranging and with 3 inner wall in close contact with of steel needle along its axis direction in the annular guide way 2, every annular stopper 4 all sets up along the circumferencial direction of guide way.
In order to facilitate puncture and prevent the steel needle 3 from scratching a patient, the outer edge surface of the left end of the sleeve 1 is tangent to the outer edge surface of the steel needle 3.
In order to facilitate the medical staff to hold the steel needle 3 and take out the steel needle 3, the right side of the steel needle 3 is provided with a first handle 5 positioned at the rear side of the sleeve 1, and the front side of the sleeve 1 is provided with a second handle 6 positioned at the left side of the opening at the right end of the annular guide groove 2.
In order to fix the sleeve 1 conveniently, a fixing sticker 7 positioned below the second handle 6 is arranged on the lower side of the sleeve 1, and fixing glue is arranged on the lower surface of the fixing sticker 7.
In order to prevent blood from flowing back conveniently, the right end of the sleeve 1 is fixedly connected with a catheter 8, and a one-way valve 9 which can flow towards the direction of the sleeve 1 is arranged in the catheter 8.
In order to be conveniently connected with a disposable syringe and play a better role in fixing, the right end of the conduit 8 is slidably connected with a filter 10, a disposable infusion tube 11 is arranged on the right side of the filter 10, and the right end of the conduit 8 is provided with a clamping hook 12 which is positioned on the upper side and the lower side of the conduit and can be clamped on the right end face of the filter 10.
When the utility model is used, the disposable infusion tube 11 is firstly connected, the end part of the filter 10 is inserted into the right end of the guide tube 8, the clamping hook 12 is buckled on the right end surface of the filter 10 to prevent the filter from falling off, the disposable infusion tube 11 is arranged at the right end of the filter 10, and the left end of the disposable infusion tube 11 is connected with the liquid medicine bottle;
then, the first handle 5 is held by the right hand, the steel needle 3 extending out of the left end of the sleeve 1 is inserted into a blood vessel of a patient through the inclined plane at the left end of the steel needle 3 at the position of the patient needing puncture, the steel needle 3 can carry the sleeve 1 to be inserted into the blood vessel of the patient due to the fact that the outer edge surface of the left end of the sleeve 1 is tangent to the outer edge surface of the steel needle 3, the steel needle 3 located in the annular guide groove 2 stops puncture when the outer edge surface of the steel needle 3 is tightly contacted with the inner wall of the annular guide groove 2 under the filling of the annular plug 4, outside air is prevented from entering, when the steel needle 3 carries the sleeve 1 to be inserted into the proper position of the blood vessel of the patient, the puncture is stopped, then the second handle 6 is held by the left hand, the steel needle 3 is withdrawn backwards by the right hand, and the steel needle 3 is withdrawn backwards due to the fact that the second handle 6 is located on the sleeve 1, and the;
