Example 1

The embodiment provides a novel indwelling needle, as shown in fig. 1-5, including indwelling needle main part 11 and the puncture steel needle 12 of pegging graft in indwelling needle main part 11, the bottom of indwelling needle main part 11 is provided with needle file 2, needle file 2 is including being the slice and laminating the flexible glue paster 21 on skin, be located flexible glue paster 21 top and with flexible glue paster 21 fixed take seat 22, be located and take seat 22 one side flexible glue paster 21 a plurality of fixed strips 23 on the surface and be located and take seat 22 opposite side flexible glue paster 21 hanging plate 24 on the surface, indwelling needle main part 11 is lapped at the top of taking seat 22, hanging hole 23a has been seted up to the head position department of fixed strip 23, fixed strip 23 is walked around the back from the top of indwelling needle main part 11 and is hung on hanging plate 24 through hanging hole 23 a. After the remaining needle 1 is punctured, the needle seat 2 is arranged between the remaining needle body 11 and the skin of the patient to enable the needle seat 2 to be attached to the skin of the patient, so that when the remaining needle 1 is attached to the skin of the patient through a sticking film, the compressive stress generated by the needle seat 2 can be directly applied to the needle seat 2 and is dispersed by the needle seat 2, and the compression on the skin of the patient is reduced.

In this embodiment, the indwelling needle body 11 has a first end integrally formed with the indwelling catheter 111, a side end of the indwelling needle body 11 is integrally formed with the side connector 112, the end of the side connector 112 is connected to the connecting catheter 113, and the indwelling needle body 11, the indwelling catheter 111, the side connector 112 and the connecting catheter 113 are all made of medical silica gel and are communicated with each other, so that the medical liquid can be injected into the patient through the connecting catheter 113 while the pressure of the indwelling needle body 11 on the skin is reduced.

Specifically, the tail end of the indwelling needle body 11 is open and is sleeved with an isolating plug 114, the puncture steel needle 12 extends out from the head end of the indwelling catheter 111 after passing through the isolating plug 114, and the isolating plug 114 isolates the tail end of the indwelling needle body 11 from the outside, so that contaminants such as bacteria and the like are prevented from entering the indwelling needle body 11.

Furthermore, the end of the puncture steel needle 12 is embedded in the sleeve 121, the needle holding handle 122 is integrally formed at the side end of the sleeve 121, the sleeve 121 is made of hard PC plastic, and the sleeve 121 is long and can play a role in fixing the direction and the force of the puncture steel needle 12 during puncture.

In addition, the soft adhesive sheet 21, the seat 22 and the fixing strip 23 are integrally formed, and the top end of the seat 22 is provided with a groove 22a fitting with the outer surface contour of the indwelling needle body 11, so that the indwelling needle body 11 is limited in the groove 22 a.

It is worth noting that the bottom end integrated into one piece of link plate 24 has chimb 241, chimb 241 inlays and establishes in the inside of flexible glue paster 21, after the puncture is accomplished, will keep somewhere needle main part 11 overlap joint in taking groove 22a and hold the end of fixed strip 23 and hang fixed strip 23 on link plate 24, make and keep somewhere needle main part 11 and be fixed on needle file 2, this moment under chimb 241's effect, link plate 24 articulates on flexible glue paster 21, prevent that link plate 24 from droing from flexible glue paster 21 because of receiving the pulling force.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the description in the above embodiments and the description is only preferred examples of the present invention, and is not intended to limit the present invention, and that the present invention can have various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications all fall into the scope of the claimed invention.
