Abstract
The utility model discloses an infusion alarm capable of timely reminding to exchange liquid or pull out an infusion needle. The infusion alarm comprises a scale plate, wherein the scale plate is arranged behind a spring, a scale hole is formed in one side of the scale plate, and a scale plug which is in an inverted L shape is inserted in the scale hole; a static contact is connected to the lower end of the scale plug in an insulating way, a connecting rod between a lifting hook and the spring is connected with the left end of a horizontal bar, a moving contact which is in insulting connection with the horizontal bar is arranged at the right end of the horizontal bar, and the moving contact and the static contact are oppositely arranged; the moving contact and the static contact are electrically connected with the alarm; the moving contact and the static contact are electrically connected with a beeper. When liquid in a bottle is totally infused, the moving contact is in contact with the static contact, the alarm or the beeper is connected, and an accompanying relative, a nurse or a patient is timely reminded to exchange the liquid or pull out the infusion needle.
Description
Technical field
This utility model relates to alarm device, particularly a kind of infusion alarm.
Background technology
Whether patient is in when transfusion, need to accompany and attend to, that nurse or patient oneself often check that liquid in infusion bottle also has is how many, according to how many decisions of liquid need to change liquid or pull out transfusion needle.Sometimes owing to checking not in time, especially when infuse the late into the night, accompany and attend to, easily there is the phenomenon of dozing off in nurse or patient, in bottle, do not have in the situation of liquid, in the time that liquid goes downwards to certain height in tube for transfusion, due to the pressure balance in endovascular pressure and tube for transfusion, transfusion can stop automatically, now the liquid level in transfusion device is positioned at dripping below kettle on transfusion device, also often occurs blood back phenomenon.Change when liquid, need to be by the Bas Discharged gas dripping below kettle, then infuse, bring unnecessary trouble to transfusion.
Summary of the invention
The technical problem that this utility model solves is to provide a kind of prompting changing liquid in time or pulls out the infusion alarm of transfusion needle.
A kind of infusion alarm, include spring scale, spring scale is made up of draw ring, graduated tile, spring, suspension hook, and graduated tile is positioned at after spring, and described graduated tile one side is provided with scale hole, in scale hole, be inserted with scale plug, scale plug is inverted L-shaped, and stationary contact insulation is connected to the lower end of scale plug, and the connecting rod between suspension hook and spring is connected with transverse bar left end, transverse bar right-hand member is provided with and the transverse bar movable contact being connected that insulate, and movable contact and stationary contact are oppositely arranged.
Described movable contact and stationary contact are electrically connected with alarm.
Described movable contact and stationary contact are electrically connected with calling set.
Described graduated tile one side 2-4 the scale hole that be arranged above and below.
Described graduated tile one side 3 the scale holes that have been arranged above and below.
Technique effect of the present utility model is, when transfusion, infusion bottle is hung on drag hook, stationary contact is located in the scale hole matching with this infusion bottle, in the time that liquid in infusion bottle reduces, under spring contraction active force, movable contact moves on can be gradually, in the time that in bottle, liquid is totally lost, movable contact and stationary contact contact, and alarm or calling set are connected, can remind in time accompany and attend to, nurse or patient change liquid or pull out transfusion needle.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Fig. 2 is the not structural representation with scale plug of this utility model.
Fig. 3 is scale plug construction schematic diagram of the present utility model.
The specific embodiment
By reference to the accompanying drawings this utility model is described in further detail, this utility model includes spring scale, spring scale is by draw ring, graduated tile 1, spring, suspension hook 7 forms, graduated tile 1 is positioned at after spring, graduated tile 1 right side is provided with scale hole 2, in scale hole 2, be inserted with scale plug 5, scale plug 5 is inverted L-shaped, stationary contact 6 insulation are connected to the lower end of scale plug 5, connecting rod between suspension hook 7 and spring is connected with transverse bar 8 left ends, transverse bar 8 right-hand members are provided with and the transverse bar movable contact 3 being connected that insulate, movable contact 3 and stationary contact 6 are oppositely arranged, described movable contact 3 and stationary contact 6 are electrically connected with alarm 4.Movable contact 3 also can be connected with other device that can play reminding effect with stationary contact 6, such as, movable contact 3 and stationary contact 6 can be used as radio switch and use.
For giving full play to the existing calling set effect of hospital, described movable contact 3 and stationary contact 6 are electrically connected with calling set.
The specification of infusion bottle is generally 100ml, 250ml, 500ml, and also some is special, and such as human albumin is 50ml, 2-4 scale hole has been arranged above and below in described graduated tile left side according to infusion bottle specification.
Be 100ml, 250ml, 500ml through conventional infusion bottle specification, for convenience of transfusion, 3 the scale holes that have been arranged above and below in described graduated tile left side, the infusion bottle of corresponding 100ml, 250ml, 500ml.
When transfusion, scale plug 5 is inserted in the scale hole 2 corresponding with infusion bottle, liquid in infusion bottle constantly reduces in infusion process, spring is along with the minimizing of weight is upwards shunk, in the time that moving contact 3 and static contact 6 contact, alarm 4 or calling set are connected and are reported to the police or call out, remind accompany and attend to, nurse or patient change liquid or pull out transfusion needle.
