Detailed Description

The present invention will be described in further detail with reference to the accompanying fig. 1-3.

A trocar capable of improving the fixation degree and reducing blood return comprises a flexible infusion tube 1, a Y-shaped connecting piece 2 and a needle tube 3 which are respectively connected with two ends of the infusion tube 1, wherein a Y-shaped channel is arranged in the connecting piece 2, a left inlet 4 and a right inlet 5 which are communicated with the channel are arranged at the upper end of the connecting piece 2, an outlet 6 is arranged at the lower end of the connecting piece 2, and part of the outlet 6 is connected with the infusion tube 1; a liquid outlet 7 is arranged on the needle tube 3, and an inverted Y-shaped transition piece 8 is arranged at one end of the needle tube 3 connected with the infusion tube 1; the infusion tube 1 is also provided with a clamping mechanism.

When the device is used for puncture, a transfusion bottle with a conveying pipe or other liquid medicine storage devices is connected by using the right inlet 5 on the connecting piece 2, then fingers hold the transition piece 8 for puncture, and after the needle tube 3 is punctured to the position below the skin, the medical adhesive tape is bonded on the pipeline of the transfusion tube 1 so as to realize the fixing function; when the liquid medicine is reduced in the infusion process, the infusion tube 1 is clamped by the clamping mechanism, so that the function of secondary pressurization is realized.

Structurally, the transition piece 8 is arranged, so that the function of secondarily fixing the upper part of the needle tube 3 is realized, the fixing area of the adhesive tape is enlarged, and the puncture and holding are convenient; in the fixing process, the adhesive tape is wound on the local position of the transition piece 8, and the medical adhesive tape is fixed on the transition piece 8 due to the fact that one end of the transition piece 8 is connected with the needle tube 3, so that the fixing firmness degree is improved. Moreover, owing to set up connecting piece 2 to play and stock the transition effect between the liquid mechanism, make the sticky tape fix between connecting piece 2 and transition piece 8, thereby convenience of customers operates. In order to further improve the effect of preventing blood return, the holding mechanism is provided at a position close to the puncture point.

The left inlet 4 is sleeved with a protective cap 9, the right inlet 5 is provided with an external thread 10, and the connecting piece 2 is sleeved outside the infusion tube 1 through the lower end thereof.

In the process of puncture and non-puncture, the protective cap 9 is directly taken down from the left inlet 4 or covered on the left inlet, thereby ensuring the smooth proceeding of the puncture and transfusion process. Due to the arrangement of the structure with the protective cap 9 and the Y-shaped connecting piece 2, positive pressure connection is ensured, and the function of preventing blood return is achieved. In addition, in order to reduce the occurrence of the puncture phenomenon, a needle head is not optionally arranged.

The transition piece 8 comprises two branch pipes 11, wherein one branch pipe 11 is respectively connected with the infusion tube 1 and the needle tube 3 through two ends of the branch pipe, the other branch pipe 11 is provided with a side wing 12 for pinching, and the side wing 12 is in a sheet shape.

The side wings 12 realize the function of facilitating medical care personnel to hold and then facilitate puncture, thereby reducing the possibility of puncture and improving the success rate of puncture.

The side wings 12 extend outwards from one end of the branch pipe 11, and the side wings 12 are fixedly connected with the branch pipe 11; the branch pipe 11 and the needle tube 3 are on the same straight line; the side wings 12 are provided with anti-slip bumps 13 on the surface contacting with fingers.

The anti-slip convex points 13 are dot-shaped structures with improved friction degree and are uniformly distributed on the side wings 12, so that the effect of facilitating practical operation of a user is achieved, and the possibility of puncture and puncture is further reduced.

The clamping mechanism comprises a clamp 14 movably sleeved on the infusion tube 1, and the infusion tube 1 is in a transparent tubular shape.

The clamp 13 can be closed or opened by adopting the existing single-hand clamp (such as a Chinese clamp), so that the circulation state in the infusion tube 1 is conveniently controlled, and the possibility of blood return is reduced.

The transition piece 8 is provided as a flexible structure.

The present invention and the embodiments thereof have been described above, but the description is not limited thereto, and the embodiment shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. In summary, those skilled in the art should understand that they should not be limited to the embodiments described above, and that they can design the similar structure and embodiments without departing from the spirit of the invention.
