Detailed Description

The present invention will be described in detail with reference to fig. 1 to 2.

The utility model discloses a novel blood vessel intubate assistor, including first needle body 1 and with 1 complex second needle body 2 of first needle body, first needle body is provided with the first recess 11 that supplies intubate 34 to pass through, and second needle body 2 is provided with the second recess 21 that supplies intubate 34 to pass through, and this kind of intubate is thinner usually, belongs to soft pipe, the front end of first needle body, second needle body all is provided with pinpoint portion 31, first recess, second recess extend pinpoint portion respectively, first needle body and second needle body all are provided with the pipe position of putting that supplies the intubate to penetrate, and two pipe positions of putting merge formation put tube hole 32, the rear portion activity hinge joint of first needle body, second needle body. The using principle of the assistor is as follows: firstly, an external insertion tube of the assistor is sleeved in the tube placing hole and penetrates to the tip part of the needle, then the first needle body and the second needle body are combined to form a needle head, namely the tip part of the needle is utilized to puncture a blood vessel to penetrate the blood vessel, then the assistor is flatly placed on the blood vessel, then the required insertion tube is inserted into the auxiliary device, after the insertion tube is fixed, the assistor is withdrawn, the first needle body and the second needle body are opened, and the assistor is separated from the insertion tube.

In this technical scheme, the inclination A of pinpoint portion is 25 ~ 35 degrees. Experiments show that the optimal 30 degrees can be selected, so that the cannula can be more smoothly placed into the blood vessel.

In the technical scheme, the tube placing hole is a waist circular hole. The waist round hole enables the cannula to have more operation space when being placed in, and the pinching action of hands on the rear part of the needle body is not influenced.

Therefore, the tube placing hole is preferably arranged in the middle of the first needle body and the second needle body.

In order to keep the first needle body and the second needle body in a combined needle-shaped state normally for a long time, a tension spring 33 is connected between the first needle body 1 and the second needle body 2. Namely, under the action of the tension spring 33, the first needle body and the second needle body always keep a combined state, after the insertion is completed, the first needle body and the second needle body can be separated by utilizing the external force of a hand of a person, so that the cannula is taken off from the auxiliary device, and then the first needle body and the second needle body are automatically combined after being loosened under the tension spring 33.

Experiments show that the diameter of the combined first groove and the second groove is greater than or equal to the outer diameter of the cannula by 0.01 mm. In this way, the delivery of the soft cannula into the blood vessel can be maximally ensured.

In the technical scheme, the first needle body and the second needle body are made of metal materials. Generally, stainless steel for medical use is selected, which facilitates sterilization and increases the service life.

The above description is only for the preferred embodiment of the present invention, and for those skilled in the art, there may be variations in the embodiments and applications according to the spirit of the present invention, and the content of the description should not be construed as a limitation to the present invention.
