Abstract
The utility model relates to a medical transfusion alarming device which comprises a installation seat (1) for supporting the transfusion bottle, a beam transmitting tube (2), a beam receiving tube and a alarm system; the installation seat (1) is provided with a installation hole which fits the lower taper of the transfusion bottle (7). The utility model is characterized in that the beam receiving tube is composed of a first beam receiving tube (3) and a second beam receiving tube (4), the direction of the beam transmitting tube (2) and the horizontal surface form an acute angle Talta, the connecting line between the beam transmitting tube (2) and the first beam receiving tube (3) should pass the central axis OO'of the transfusion bottle, the beam transmitting tube (2) and the second beam receiving tube (4) are symmetrical with the central axis OO'of the transfusion bottle as the symmetry axis. The utility model has the advantages of high sensitivity, safe and relation operation, simple structure and low price, which can reduce the manpower and spirit burden to improve the quality of the nursing service.
Description
Technical field
This utility model relates to the patient infusion device that a kind of hospital clinical uses, and specifically, relates to a kind of medical infusion alarm.
Background technology
The infusion set of hospital clinical use at present mostly by artificial supervision transfusion, when the medicinal liquid in the infusion bottle will be totally lost, manually cuts off tube for transfusion by nurse's supervision.Chinese patent CN1473630A discloses a kind of medical infusion alarm, this transfusion device is made up of light infrared transmitting tube and infrared receiving tube, its theory is when the liquid in the infusion bottle reaches critical state, the light that infrared transmitting tube sends can be received by infrared receiving tube, after infrared receiving tube receives light, just can send alarm signal, and send chimes of doom, so that medical personnel take measures rapidly after hearing chimes of doom by self-insurance news Chinese percussion instrument power supply circuits control news Chinese percussion instrument.But the deficiency that this medical infusion alarm exists is, because the light that infrared transmitting tube sends can pass medicinal liquid and arrive infrared receiving tube always, when the liquid in the infusion bottle reaches critical state, just the light intensity of infrared receiving tube reception increases, thereby cause the sensitivity of light receiver work to be lowered, can not in time send alarm signal, its safety, reliability are difficult to reach requirement.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of working sensitivity height, safe and reliable medical infusion alarm.
The technical scheme that realizes above-mentioned purpose is: a kind of medical infusion alarm, comprise the mount pad, light emission pipe, light receiving tube and the alarm composition that support infusion bottle, has the installing hole that matches with the infusion bottle lower taper on the mount pad, the light receiving tube is made up of the first light receiving tube and the second light receiving tube, the direction of light emission pipe and horizontal plane θ in an acute angle, the line of the light emission pipe and the first light receiving tube should be by the central axis oo ' of infusion bottle, and the light emission pipe and the second light receiving tube are symmetry with the central axis oo ' of infusion bottle.
After adopting technique scheme, during the transfusion beginning, full bottle, light emission pipe emission light, light passes the medicinal liquid in the infusion bottle, because the line of the light emission pipe and the first light receiving tube passes through the central axis oo ' of infusion bottle, first receiving tube can receive light, the first receiving tube conducting gives a green light; When liquid level continues to drop to with the corresponding caution liquid level in the first receiving tube position time, first receiving tube does not receive the light that the light emission pipe is sent, and first receiving tube opens circuit, and the control alarm sends alerting.When liquid level continues to descend, arrive by liquid level, the light that the light emission pipe sends reflects through liquid level, because the light emission pipe and the second light receiving tube are symmetry with the central axis oo ' of infusion bottle, therefore reflected light is just in time received by second receiving tube, and the second receiving tube conducting is sent signal and made the news Chinese percussion instrument of alarm send chimes of doom, make infusion bottle stop transfusion by other control device simultaneously, guarantee patient's safety.Above-mentioned work process is not only highly sensitive, and safe and reliable, is not subjected to the influence of weather, environment simultaneously.

Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is a fundamental diagram of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples this utility model is described in further detail.
As Fig. 1,2, shown in 3, a kind of medical infusion alarm, comprise the mount pad 1 that supports infusion bottle, light emission pipe 2, light receiving tube and alarm are formed, has the installing hole that matches with infusion bottle 7 lower taper on the mount pad 1, the light receiving tube is made up of the first light receiving tube 3 and the second light receiving tube 4, the direction of light emission pipe 2 and horizontal plane θ in an acute angle, the line of the light emission pipe 2 and the first light receiving tube 3 should be by the central axis oo ' of infusion bottle 7, and the light emission pipe 2 and the second light receiving tube 4 are symmetry with the central axis oo ' of infusion bottle 7.Acute angle theta is the angle of incidence of the light of light emission pipe 2 emissions, and this angle is determined by medium.And guarantee when this angle light total reflection, not refraction.
As shown in Figure 2, mount pad 1 is " C " shape.This structure helps the installation of infusion bottle 7.
As shown in Figure 1, the light emission pipe 2 and the first light receiving tube 3, the second light receiving tube 4 all are positioned at mount pad 1.Adopt this structure not only to be easy to make, and easy to adjust.But when using, mount pad should keep level.
Work process of the present utility model is as follows: during the transfusion beginning, and full bottle, light emission pipe 2 emission light, light passes the medicinal liquid in the infusion bottle 7, and first receiving tube 3 can receive light, and 3 conductings of first receiving tube give a green light; When liquid level continues to drop to with the corresponding caution liquid level 5 in first receiving tube, 3 positions the time, first receiving tube 3 does not receive the light that light emission pipe 2 is sent, and first receiving tube 3 opens circuit, and the control alarm sends alerting.When liquid level continues to descend, arrive by liquid level 6, the light that light emission pipe 2 sends reflects through liquid level, reflected light is just in time received by second receiving tube 4,4 conductings of second receptor, send signal and make the news Chinese percussion instrument of alarm send chimes of doom, make infusion bottle 7 stop transfusion by other control device simultaneously, guarantee patient's safety.
This utility model is simple in structure, and low price can alleviate manpower and mental burden, improves nursing service quality.Adopt wired or wireless signal, can control by computer networking, a nurse can monitor a plurality of infusion bottles.
