Abstract
The utility model relates to a medical transfusion alarm. The utility model is characterized in that the utility model comprises a needle head for a transfusion pipe, which is inserted on a piston of an infusion bottle, and an audio alarm circuit connected with the needle head for a transfusion pipe into an integral body, wherein, the needle head for a transfusion pipe comprises an air channel having an air inlet and an air outlet and a transfusion channel communicated with liquid in the infusion bottle through a transfusion inlet; an alarm switch of the audio alarm circuit is composed of a pair of upper and lower electrodes for the alarm switch, which is controlled by water lever inside the infusion bottle to switch on or switch off and is arranged on the needle head. The apparatus can be applied to the medical transfusion device. When the liquid level in the infusion bottle is lower than the specified height, the utility model can automatically alarm. The utility model has the advantages of simple structure and safety.
Description
Technical field: this utility model relates to a kind of medical infusion alarm.
Prior art: there is a bigger problem in present employed medical Transfusion device; it is exactly the time of uncontrollable transfusion; bring very big mental pressure for like this patient and nursing staff; especially for some patients that can not take care of oneself; if no special messenger keeps an eye on, when liquid level is lower than specified altitude in the infusion bottle, owing to can not in time notifying the nurse to change bottle or getting pin; regular meeting causes in the air input patient body or the blood back phenomenon, causes bad consequence.
Summary of the invention: medical infusion alarm capable of automatic alarm when the purpose of this utility model is to provide a kind of liquid level in infusion bottle to be lower than specified altitude, this device construction is simple, and is novel, the security performance height.
This utility model is to constitute like this, it comprises tube for transfusion syringe needle that is plugged on the infusion bottle piston and the audible alarm circuit that joins together with the tube for transfusion syringe needle, the tube for transfusion syringe needle comprises air duct with air ports and the infusion channel of passing through fluid connection in transfusion import and the infusion bottle, and the alarm switch of described audible alarm circuit is made of a pair of alarm switch upper/lower electrode of being located on the syringe needle by water level control break-make in the infusion bottle.
During work, liquid enters infusion channel through the transfusion import in the infusion bottle, is entered in the tube for transfusion by infusion channel again, and air then enters air duct by air intlet from the external world, is entered in the infusion bottle from air duct by air outlet slit again.Because of the alarm switch upper/lower electrode is inserted in the infusion syrup, instrument was in the monitored state of awaiting orders when the patient infused, and audible alarm circuit is not worked; When infusion syrup drips to when being lower than the alarm switch top electrode, audible alarm circuit begins to report to the police, and after changing bottle, instrument just recovers the monitored state of awaiting orders.
This utility model product is applied in the medical Transfusion device, the safety when helping improving patient infusion greatly, thus reduce nursing staff's burden, very big facilitation is played in the development of medical treatment and nursing cause.
Description of drawings: Fig. 1 is this utility model embodiment organigram,
Fig. 2 is an embodiment warning circuit sketch map.
The specific embodiment: embodiment of the present utility model comprises tube for transfusion syringe needle that is plugged on infusion bottle 1 piston 2 and the audible alarm circuit that joins together with the tube for transfusion syringe needle, the tube for transfusion syringe needle comprises air duct 5 with air ports 3,4 and the infusion channel 7 of passing through fluid connection in transfusion import 6 and the infusion bottle, and the alarm switch of described audible alarm circuit is made of a pair of alarm switch upper/lower electrode A, the B by water level control break-make in the infusion bottle that is located on the syringe needle.
Above-mentioned tube for transfusion syringe needle is made of outer tube and the interior pipe that is used for air inlet, outer tube is composed in series by last plastic insulating tube 8 and following stainless steel tube 9, interior pipe is composed in series by last stainless steel tube 10 and following plastic insulating tube 11, the described stainless steel tube top seal of going up forms taper needle point structure 12, the top edge perimembranous of last plastic insulating tube is coated on the following perimembranous of taper needle point structure, interlayer between outer tube and the interior pipe forms infusion channel, described transfusion import is positioned on the following stainless steel tube sidepiece of outer tube, the last stainless steel tube of interior pipe and the demarcation line of following plastic insulating tube are positioned at the top of transfusion import, have the air outlet slit 3 that leads to interior pipe internal air passageway on the upper lateral part of outer tube, manage the lower end in the air intlet 4 that is used for being communicated with extraneous air is located at and be positioned at infusion bottle piston below.
The last stainless steel tube of above-mentioned interior pipe is the alarm switch top electrode, and the following stainless steel tube of described outer tube is the alarm switch bottom electrode.Adopt stainless steel tube not only to help conduction, and can effectively prevent corrosion as the alarm switch upper/lower electrode.
Above-mentioned air intlet is provided with the lid 13 in order to open and close this air intlet.When patient infusion, lid to be opened, outside air is promptly along with the carrying out of infusion process enters in the infusion bottle by air duct.
Shown in Fig. 2 embodiment warning circuit sketch map, when the alarm switch upper/lower electrode because of infusion bottle in during the higher conducting of water level, audion 3DG1 conducting, 3DG2 is high saturated because of base potential, so be in cut-off state, phonological component does not have electricity and can not work, when water level is low, 3DG1 ends, the 3DG2 conducting, and audible alarm circuit gets electric and reports to the police.The power consumption of this utility model operating circuit is economic, and when it is in when awaiting orders monitored state, operating current is no more than 5 μ A.
This utility model product configurations is simple, and is novel, be applied in the medical Transfusion device, and the safety when helping improving patient infusion greatly, thus reduce nursing staff's burden, very big facilitation has been played in the development of medical treatment and nursing cause.
