Embodiment 1

[0030] A multifunctional indwelling needle, such as Figure 1 to Figure 5 As shown, it includes the indwelling needle body 1, the extension tube 2 installed at the bottom of the indwelling needle body 1, and the infusion joint 3 installed at the other end of the extension tube 2. One end of the indwelling needle body 1 is provided with a hose 11, and the outer wall of the indwelling needle body 1 is There is a chute 12, the top of the chute 12 is provided with a slider 13, the inner bottom of the indwelling needle body 1 is equipped with a steel needle 14, and the inner wall of the indwelling needle body 1 is respectively embedded with an isolation plug 15 and a one-way valve switch 16. One end of the valve switch 16 is provided with a one-way valve regulating rod 17, and the top of the one-way valve regulating rod 17 is provided with a plurality of mesh holes 18, and the bottom end of the flexible pipe 11 is equipped with a first one-way valve 19, a slide block 13 and The sli...

Embodiment 2

[0036] As the second embodiment of the present invention, in order to avoid the reflux phenomenon of the infusion connector 3, the inventors improved the structure of the infusion connector 3, as Image 6 As shown, the infusion joint 3 includes a pair of connectors 31, one end of the connector 31 is provided with a shunt pipe 32, the bottom of the shunt pipe 32 is provided with a confluence pipe 34, and the inner wall of the shunt pipe 32 is provided with a second unit near the side of the connector 31. The valve 33, the shunt pipe 32 and the confluence pipe 34 are integrally formed.

[0037] In this embodiment, both the shunt pipe 32 and the confluence pipe 34 are made of drinking hose material, which is environmentally friendly and non-toxic, and has certain toughness and is easy to bend.

[0038] Concretely, the second one-way valve 33 adopts the type 718 water-stop medical plastic one-way valve produced by Foshan Bious Valve Co., Ltd. In addition, the one-way valve involve...

Embodiment 3

[0040] As the third embodiment of the present invention, in order to increase the diversity of the overall functions of the indwelling needle body 1, the inventors made improvements to the structure of the indwelling needle body 1, as a preferred example, as Figure 7 As shown, the inside of the one-way valve adjusting rod 17 is a hollow structure, and the inside of the one-way valve adjusting rod 17 is provided with a pressure wire 171, and one end of the pressure wire 171 is respectively equipped with a first probe 172 and a second probe 173, and the pressure wire 171 An electric wire 174 is provided at the other end of the electric wire 174, and an adapter 175 is installed at the other end of the electric wire 174, and the pressure wire 171 runs through the one-way valve adjusting rod 17.

[0041] In this embodiment, the pressure wire 171 adopts the FFR series pressure wire produced by the St. Jude Company of the United States, and its supporting circuit can also be provided...

Abstract

The invention relates to the technical field of machinery, and in particular relates to a multi-purpose indwelling needle. The indwelling needle comprises an indwelling needle body, an extension pipemounted at the bottom of the indwelling needle body, and an infusion joint mounted at the other end of the extension tube. For the multi-purpose indwelling needle, a first one-way valve is arranged atthe tail end of a hose, so that liquid or blood only can enter and can not exit; meanwhile, an infusion valve is cancelled, so that the pressure injuries caused by the infusion valve can be avoided,tblood can flow out from mesh openings, on one hand, whether a steel needle is inserted into the vein or not can be confirmed, on the other hand, medical workers can carry out blood sampling work conveniently, liquid can enter the hose directly through the indwelling needle body, and then vein treatment is carried out; backflow of liquid or blood also can be prevented, and moreover, through a second one-way valve, two ends can realize smooth liquid supplementing; and in addition, due to the arrangement of a first probe and a second probe, the blood pressure, heart rate, SPO2 and body temperature can be rapidly measured.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a multifunctional indwelling needle. Background technique [0002] The indwelling needles currently used clinically have the following deficiencies: 1. Improper movement or body position changes on the side of the patient retaining the indwelling needle will cause the extension tube connecting the indwelling needle to the infusion end to be compressed and folded, resulting in poor infusion or even blockage of the indwelling needle; 2. The material of the infusion valve on the indwelling needle extension tube is relatively hard. For patients with fragile skin or puncture in the pressured part of the body or a change in body position, the skin of the pressured part will be reddened or even ruptured; 3. Ordinary There is a large space between the end of the indwelling needle or the positive pressure indwelling needle end hose and the valve of the extension tube. When blood press...
