Abstract

The utility model relates to a safe auxiliary device used for the intravenous transfusion, which is an infusion alarm. A support frame is arranged in a box composed of a casing and an upper cover. A draw rod whose one end is provided with a hook passes through a circular hole at the box bottom and a circular hole on the support frame. The other end of the draw rod is sheathed with a spring. In addition, a contact cap is screwed on the other end of the draw rod. The contact cap is contacted with a movable contact in switch contacts arranged in the box. The switch contacts are connected with an alarm circuit arranged in the box.

Description

Infusion alarm

This utility model relates to a kind of safe auxiliary device that venous transfusion is used, i.e. alarm for infusion of being adapted to.

Traditional venous transfusion is to observe medicinal liquid content in the infusion bottle by the people, and there are many shortcomings in this, the one, very easily cause the nervous and tired of observer, and the 2nd, be difficult to guarantee the accuracy of amount of infusion, the 3rd, be easy to generate defeated empty medicinal liquid, bring the pain of injury to the patient.

The purpose of this utility model just is to avoid the shortcoming of prior art, and provide a kind of when the bottle inner liquid medicine reaches given marginal value, can send the sound and light alarm signal rapidly in time and remind the relevant personnel to remove or change the alarm for infusion of infusion bottle, this alarm for infusion should be able to be responded to the weight of the infusion bottle that contains medicinal liquid.

This utility model is to adopt following measure to realize its purpose.

One support is arranged in the box of being made up of housing and loam cake, the pull bar that one end has suspension hook passes the circular hole of box bottom and the circular hole on the support, the other end of pull bar is with a spring, and screw in one and touch medicated cap, this touches medicated cap and the movable contact that is placed in the switch contact in the box touches mutually, and the switch contact warning circuit interior with being installed in box is connected; Warning circuit is an acoustics circuit of being made up of power supply, switch, light emitting diode, speaker and integrated circuit; And the battery of using as power supply is being laid in the both sides of box draw-in bar, settles suspension ring on the top of box.Switch contact is two dynamic and static contacts that are fixed on the housing.

The drawing of accompanying drawing is described as follows:

Fig. 1 is this utility model front view.

Fig. 2 is this utility model right view.

Fig. 3 is the cutaway view along A-A direction among Fig. 2.

Fig. 4 is the cutaway view along B-B direction among Fig. 1.

Fig. 5 is the circuit diagram of warning circuit.

Below in conjunction with accompanying drawing this utility model is further described.

Housing of the present utility model (1) and loam cake (13) fasten and form a box (12), a support (14) is arranged on the housing (1), the pull bar (5) that one end has suspension hook (15) passes the circular hole (16) of box (12) bottom and the circular hole (17) on the support (14), the other end of pull bar (5) is with a spring (4), and screw in one and touch medicated cap (20), movable contact (19) in the switch contact (18) in this touches medicated cap (20) and is placed in box (12) touches mutually, switch contact (18) is two and is fixed on moving on the housing (1), stationary contact (19), (2), moving, stationary contact (19), (2) forming the switch warning circuit interior with being installed in box (12) is connected, warning circuit be one by power supply E, on and off switch K, contact switch J, light emitting diode D, the acoustics circuit that speaker Y and IC are formed, speaker (6) and light emitting diode (8) all are placed on the housing (1), and housing has voice hole and light hole on (1).And at the top of box (12) arrangement suspension ring (9), laying the battery of using as power supply E (10) in the both sides of box (12) draw-in bar (5), also settle an on and off switch (7) in the bottom of housing (1), pull bar (5) can back and forth be worn in circular hole (16) and (17).During use, infusion bottle is hung up by this utility model, turn on the power switch (7), during beginning, because the weight of infusion bottle and medicinal liquid is by pull bar (5) and touch medicated cap (2) and force spring (4) to compress, along with the minimizing of infusion bottle inner liquid medicine, under the effect of spring (4), touch medicated cap (20) and constantly rise, movable contact (19) in pull switch contact (18) is constantly near stationary contact (2) simultaneously, when the bottle inner liquid medicine reaches given marginal value, moving, stationary contact (19), (2) butt, switch J conducting, warning circuit work, be that speaker sends sound equipment, light emitting diode sends light, reminds the relevant personnel to remove or change infusion bottle.

This utility model can send the sound and light alarm signal rapidly in time, and the personnel that need not stay in the ward to look after the patient night and day check constantly, alleviate the relevant personnel's labor intensity, have made things convenient for medical personnel's management, is particularly suitable for transfusion continuously and transfusion at night, alleviates patient's the pain of injury.
