Abstract

The utility model discloses an alarm for preventing the completion of saline, comprising a saline bottle, a liquid guiding tube, a net-shaped bracket, a spring, a gasket and the like. The spring is fixed on the inner wall of an opening of the net-shaped bracket, a circular hole is arranged in the middle of the gasket which is arranged on the spring, the liquid guiding tube is inserted at the lower end of the saline bottle, an alarm circuit is arranged in the net-shaped bracket and consists of a power supply, a buzzer, an upper elastic piece and a lower elastic piece, the upper elastic piece and the lower elastic piece are respectively connected with a cathode and an anode of the power supply, the buzzer is connected in the alarm circuit in series, the upper elastic piece and the lower elastic piece are staggered up and down, arranged above the saline bottle, and separated from the saline bottle by a certain distance. The alarm can effectively remind a patient or a caregiver when the saline is nearly used up, thus preventing the corresponding safety accidents; and the alarm has a simple structure, is convenient to use, low in cost, and convenient for mass production.

Description

A kind of alarm that prevents that saline from having hung

Technical field

This utility model relates to a kind of alarm, more particularly relates to a kind of alarm that prevents that saline from having hung.

Background technology

Venous transfusion be clinical in one of modal treatment means, must constantly make an inspection tour by the nurse during transfusion, perhaps family members accompany and attend to.Long owing to hanging the brinish time; Patient and nurse personnel are difficult to keep constantly clear-headed state; Perhaps because other reasons, can't find in time that probably saline has hung this situation, if in time do not pull out syringe needle but saline has hung; Will cause blood to reflux, damage for patient's health.

Summary of the invention

The purpose of this utility model is: the alarm that provides a kind of easy to use, cheap prevented saline to hang for the defective that overcomes above-mentioned existing technology existence.

A kind of alarm that prevents that saline from having hung of this utility model comprises saline bottle 1, catheter 2, netted base body 3, spring 4, pad 5 etc.; Said described spring 4 is fixed on the inwall of opening 6 of netted base body 3, has circular hole 7 in the middle of the described pad 5, and described pad 5 is placed in above the spring 4; Described catheter 2 is inserted in the lower end of saline bottle 1; Be mounted with warning circuit 8 in the described netted base body 3, described warning circuit 8 by power supply 9, father-in-law ring device 10, go up shell fragment 11, shell fragment 12 is formed down, describedly goes up shell fragment 11 and following shell fragment 12 are connected in power supply 9 respectively through lead both positive and negative polarity place; The described father-in-law device 10 that rings is connected in the warning circuit 8; The described shell fragment 10 of going up staggers up and down with following shell fragment 11, and is placed on directly over the saline bottle 1, and keeps certain distance with saline bottle 1.

The utlity model has following advantage:

1. when saline has hung soon, can effectively remind patient or its ward, prevent the generation of corresponding security incident;

2. simple in structure, easy to use;

3. with low cost, be convenient to mass production.

The specific embodiment

Below in conjunction with accompanying drawing this utility model is done further to describe.

A kind of alarm that prevents that saline from having hung comprises saline bottle 1, catheter 2, netted base body 3, spring 4, pad 5 etc.; Said described spring 4 is fixed on the inwall of opening 6 of netted base body 3, has circular hole 7 in the middle of the described pad 5, and described pad 5 is placed in above the spring 4; Described catheter 2 is inserted in the lower end of saline bottle 1; Be mounted with warning circuit 8 in the described netted base body 3, described warning circuit 8 by power supply 9, father-in-law ring device 10, go up shell fragment 11, shell fragment 12 is formed down, describedly goes up shell fragment 11 and following shell fragment 12 are connected in power supply 9 respectively through lead both positive and negative polarity place; The described father-in-law device 10 that rings is connected in the warning circuit 8; The described shell fragment 10 of going up staggers up and down with following shell fragment 11, and is placed on directly over the saline bottle 1, and keeps certain distance with saline bottle 1.

During use, directly put into netted base body to saline bottle, then conduit is inserted saline bottle and get final product.When the liquid medicine in the saline bottle slowly flowed down, the whole weight of saline bottle descended, and spring slowly diastole comes, and the height of saline bottle will slowly improve.So, select a suitable spring, just can guarantee when the liquid medicine in the saline bottle has soon flowed, saline bottle can jack-up under shell fragment, shell fragment is contacted with last shell fragment, warning circuit conducting at this moment, father-in-law's device that rings sends chimes of doom immediately.

Claims
