DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] See also Figure 1-8The present invention provides a technical solution: a pediatric indwelling needle that is easy to fix, comprising a needle seat 2 for fixing a needle tube 1 and a sleeve seat 4 for fixing a sleeve 3, a branch tube 5 is fixed on the outside of the sleeve seat 4, the needle seat 2 comprises a fixing seat 6, a mounting seat 7 and a connecting piece 8, the fixing seat 6 is used to fix the needle tube 1, and the fixing seat 6 is fixed on the mounting seat 7, the mounting seat 7 fixes the branch tube 5 through the connecting piece 8, and the sleeve seat 4 is fixed by the connecting piece 8 on the mounting seat 7 so that it cannot slide, so as to keep the sleeve 3 holding the needle tube 1 and improve the success rate of needle tube puncture 1.

[0026] The connector 8 includes a sleeve portion 9 and a connecting portion 10. The two ends of the connecting portion 10 are respectively fixed to the mounting seat 7 and the sleeve portion 9. When in use, the branch pipe 5 is wrapped by the sleeve portion 9 to limit its position.

[0027] The sleeve portion 9 is made of elastic material, so that the sleeve portion 9 can be wrapped around the outside of the branch pipe 5 .

[0028] The sleeve portion 9 is provided with raised particles 11 for increasing friction, which increases friction and facilitates operation.

[0029] The fixing seat 6 is in a cylindrical structure, which facilitates the connection between the fixing seat 6 and the sleeve seat 4.

[0030] A support member 12 is provided on the outer side of the sleeve seat 4, and the support member 12 includes a support ring 13 and a slide groove 14 opened on the outer surface of the sleeve seat 4. The support ring 13 is cam-shaped and made of silicone material. After the puncture is successful, the thicker part of the support ring 13 can be rotated downward, so that the support ring 13 plays a supporting role between the sleeve seat 4 and the skin, preventing the sleeve 3 from being lifted up due to the downward pressure of the sleeve seat 4 when the tape is tied.

[0031] A connecting sleeve 16 is fixedly installed on the inner side of the supporting sleeve 13, and the connecting sleeve 16 is movably fitted with the sleeve seat 4. A clamping ring 15 is fixedly installed on the inner side of the connecting sleeve 16, and the clamping ring 15 is movably fitted with the slide groove 14. The supporting sleeve 13 can be adjusted through the clamping ring 15 and the slide groove 14. After the adjustment is completed, tape is pasted between the supporting sleeve 13 and the skin to fix it.

[0032] The upper end of the sleeve seat 4 is provided with a limiting strip 17 for facilitating tape binding, and the upper end surface of the limiting strip 17 is arc-shaped. When the tape is pasted between the sleeve seat 4 and the skin, a large gap exists between the sleeve seat 4 and the skin. Under the action of the limiting strip 17, the tape can be pasted on the arc surface of the limiting strip 17 to improve the stability of the sleeve seat 4.

[0033] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
