Embodiment 1

[0030] This embodiment is a disposable medical infusion set that automatically closes and alarms when the drip is exhausted, and the infusion set specifically includes a liquid medicine temporary storage device 1, an infusion tube 2, and a liquid medicine flow rate regulator; it is characterized in that:

[0031] The disposable medical infusion set with automatic closing and automatic alarm when the drip is exhausted is provided with a structure for automatically closing the infusion set when the medicinal liquid is exhausted:

[0032] The liquid medicine temporary storage 1 is provided with a float 4 that can move back and forth along the central axis substantially parallel to the liquid medicine temporary storage 1; there is also a structure that can ensure that the float 4 blocks the infusion channel and closes the infusion set when it falls.

[0033] The disposable medical infusion set that the present embodiment drips and automatically closes the automatic alarm also inclu...

Embodiment 2

[0041] Embodiment 2 (see attached image 3 )

[0042] The content of this embodiment is basically the same as that of Embodiment 1, and its difference mainly lies in:

[0043] 1) The alarm device 8 for the liquid medicine dripping is specifically: a block or sheet ferromagnetic material 901 is arranged on the float 4, and an electromagnetic sensor is arranged outside the liquid medicine temporary storage 1 of the infusion set 9;

[0044] During the infusion process, the user can first make the lower part of the float 4 out of the inner cavity of the hollow inner tube 5 by squeezing, etc., so that the liquid medicine temporary storage 1 is separated by the hollow inner tube 5 and the hard partition 6 The upper and lower cavities are connected, and the medicinal liquid enters the medicinal liquid temporary storage 1 from the upper infusion tube 2, and accumulates to a sufficient amount; finally, when the external force is removed, the float 4 can float in the medicinal liquid ...

Embodiment 3

[0048] The content of this embodiment is basically the same as that of Embodiment 1, and its difference mainly lies in:

[0049] 1) The alarm device 8 for dripping out of medicine is specifically: a mechanical touch switch is set near the float 4, and when the float 4 falls at the end of normal dripping, when the infusion channel is closed, the contact between the float 4 and the machine will be triggered. The associated actions between the switches meet the alarm trigger conditions.

[0050] 2) In addition, the disposable medical infusion set that automatically closes and alarms when the drip is exhausted is characterized in that: the upper part of the hollow inner tube 5 of the disposable medical infusion set that automatically closes and alarms when the drip is exhausted is provided with a temporary For the six liquid inlet holes 501 of the reservoir 1, the cross-sectional area of ​​the liquid medicine channel at the upper part of the hollow inner tube 5 in the axial direct...

Abstract

The invention discloses a dispensable medical infusion apparatus capable of automatically closing and alarming at end of dripping. The infusion apparatus concretely comprises a temporary liquid medicine container (1), an infusion tube (2) and a liquid medicine flow rate regulator, and is characterized by being provided with a structure for automatically closing the infusion tube when the liquid medicine drips out: a floater (4) capable of reciprocally moving on a central axis basically parallel to the temporary liquid medicine container (1) and a structure capable of ensuring the floater (4) blocks an infusion passage when falling down and closes the infusion apparatus are arranged in the temporary liquid medicine container (1). The dispensable medical infusion apparatus capable of automatically closing and alarming when the liquid medicine drips out is simple and effective in structure, low in cost and convenient in use. Meanwhile, the invention provides a plurality of alarming design schemes which are selectable according to actual needs. The infusion apparatus is a break through of the prior part and has foreseeable great economic and social values.

Description

technical field [0001] The invention relates to a medical transfusion device, in particular to a disposable medical transfusion device which automatically closes and alarms when the drip is exhausted. Background technique [0002] In the prior art, the medical infusion set usually cannot be automatically closed or automatically alarmed after the medicine liquid is dripped out. Although there are reports of schemes with similar functions, the structural design is generally unreasonable and cannot meet the requirements of actual use. [0003] People are eager to obtain a disposable medical infusion set with practical value and obviously better technical effect, which automatically closes and alarms when the drip is exhausted. Contents of the invention [0004] The purpose of the present invention is to provide a medical infusion set that can automatically close the infusion set and automatically alarm when the medicine liquid drips in, the technical effect is obviously bett...
