Embodiment 1

[0030]A multifunctional indwelling needle, such asFigure 1 to Figure 5As shown, it includes an indwelling needle body 1, an extension tube 2 installed at the bottom of the indwelling needle body 1, and an infusion connector 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 A chute 12 is provided. 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 adjusting rod 17, the top of the one-way valve adjusting rod 17 is provided with a plurality of mesh holes 18, and the bottom end of the hose 11 is equipped with a first one-way valve 19, a slider 13 and With the sliding fit of the sliding ...

Embodiment 2

[0036]As a second embodiment of the present invention, in order to prevent the infusion connector 3 from generating a reflux phenomenon, the present inventors have made improvements to the structure of the infusion connector 3, such asFigure 6 As shown, the infusion connector 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 manifold 34, and the inner wall of the shunt pipe 32 is provided with a second unit on the side close to the connector 31. The valve 33, the branch pipe 32 and the manifold pipe 34 are integrally formed.

[0037]In this embodiment, both the shunt pipe 32 and the manifold pipe 34 are made of drinking hose materials, which are environmentally friendly and non-toxic, and have a certain degree of toughness, which is convenient for bending.

[0038]Specifically, the second one-way valve 33 adopts a water-stop medical plastic one-way valve of model 718 produced by Foshan Bios ...

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 of the present invention made improvements to the structure of the indwelling needle body 1. As a preferred example,Figure 7 As shown, the inside of the one-way valve adjusting rod 17 is a hollow structure, 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 installed with a first probe 172 and a second probe 173, and the pressure wire 171 An electric wire 174 is installed at the other end of the electric wire 174, an adapter 175 is installed at the other end of the electric wire 174, and the pressure wire 171 penetrates the one-way valve adjusting rod 17.

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

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 technical field of machinery, in particular to a multifunctional indwelling needle.Background technique[0002]The current clinical use of indwelling needles has the following shortcomings: 1. Improper movement or postural changes of the patient's side where the indwelling needle is retained will cause the extension tube of the indwelling needle to be connected to the infusion end to be compressed and broken, resulting in poor infusion and even blockage of the indwelling needle; 2. The material of the infusion valve on the extension tube of the indwelling needle is hard. For patients with fragile skin or puncture at the pressured part of the body or a change in body position caused by pressure, the skin of the pressured part will become red and even ruptured; 3. Normal There is a large space between the end of the indwelling needle or the positive pressure indwelling needle tip tube and the extension tube valve. When measuring blood pr...
