Abstract
The utility model relates to a refraction type infusion alarm photoelectric switch, comprising a supporting seat and a photoelectric switch, wherein the center of the supporting seat is vertically provided with a round hole. A light emitting pipe and a receiving pipe of the photoelectric switch are installed on the inner wall of the round hole of the supporting seat, and a straight line between the light emitting pipe and the receiving pipe deviates from the radial line of the round hole. The supporting seat is provided with a transverse gap directly reaching the round hole, and the inner-wall upper edge of the round hole of the supporting seat is provided with a flange. The refraction type infusion alarm photoelectric switch has the advantages that as the straight line between the light emitting pipe and the receiving pipe deviates from the radial line of the round hole, the refracted angles of light emitted by the light emitting pipe are different under the two conditions of passing through air and solution, the light is not influenced by the color of the solution, and therefore corresponding switch signals can be automatically generated according to the fact whether the receiving pipe receives the light emitted by the light emitting pipe; the supporting seat is provided with the transverse gap directly reaching the round hole, so an infusion tube is conveniently penetrated into the supporting seat, and the installation is simple and convenient; the inner wall of the round hole of the supporting seat is provided with the flange, so the supporting seat can be buckled on a small infusion pot, and the use is convenient.
Description
Technical field
This utility model relates to a kind of transfusion warning photoswitch, refers to a kind of refraction type transfusion warning photoswitch especially.
Background technology
It is the common treatment means that hospital adopts that the patient is infused, and for preventing that the medicinal liquid in the medicine bottle has dripped the situation appearance that most patient does not obtain corresponding disposal yet in the infusion process, the nurse needs often to observe each patient's transfusion process, and labor intensity is very big.Therefore need a kind of device that when the transfusion process closes to an end, can send signal automatically.
The utility model content
The purpose of this utility model provides a kind of transfusion warning photoswitch, and it can send signal automatically when the transfusion process closes to an end, and is not subjected to the influence of medicinal liquid color.
The purpose of this utility model is achieved in that
A kind of refraction type transfusion warning photoswitch is characterized in that it comprises:
Supporting seat, its central vertical has circular hole;
Photoswitch, its luminous tube and receiving tube are installed on the inwall of circular hole of supporting seat, and luminous tube departs from the radial line of circular hole to the straight line between the receiving tube.
Further: the horizontal cut that has through circular hole on the described supporting seat.
Further: the inwall upper edge of the circular hole of described supporting seat is provided with bead.
The utlity model has following advantage:
1. because luminous tube departs from the radial line of circular hole to the straight line between the receiving tube, thereby the light that luminous tube sends is passing air and is passing under two kinds of situations of medicinal liquid, the refraction angle difference that is produced, and be not subjected to the influence of medicinal liquid color, thereby can whether receive the light that luminous tube sends according to receiving tube, produce corresponding switching signal automatically;
2. owing to have the horizontal cut of through circular hole on the supporting seat, can make things convenient for tube for transfusion to penetrate, thereby succinct facility is installed;
3. because the inwall upper edge of the circular hole of supporting seat is provided with bead, can be stuck on the transfusion pipkin, thus easy to use.
Description of drawings
Fig. 1 is the structural representation of this utility model first embodiment;
Fig. 2 is the structural representation of this utility model first embodiment;
Fig. 3 is transfusion in the pipkin during no medicinal liquid, the refraction situation of the light that luminous tube sends when passing air;
Fig. 4 is when in the transfusion pipkin medicinal liquid being arranged, the refraction situation of the light that luminous tube sends when passing medicinal liquid.
The specific embodiment
This utility model is a kind of refraction type transfusion warning photoswitch, and it comprises: supporting seat, and its central vertical has circular hole; Photoswitch, its luminous tube and receiving tube are installed on the inwall of circular hole of supporting seat, and luminous tube departs from the radial line of circular hole to the straight line between the receiving tube.
Below in conjunction with accompanying drawing this utility model is further described.
Embodiment 1
As shown in Figure 1, this utility model comprises a rectangular block shape supporting seat 1, its central vertical has circular hole, a photoswitch 2 is housed on the inwall of the circular hole of supporting seat 1, the luminous tube of photoswitch 2 to the straight line between the receiving tube departs from the radial line of circular hole, has the horizontal cut 4 of through circular hole on the supporting seat 1.
When this utility model is installed, make tube for transfusion pass the breach 4 of supporting seat 1 earlier, again the circular hole of supporting seat 1 is fixed in the periphery of transfusion pipkin, connect the power supply of photoswitch 2 at last, the output of photoswitch 2 is connected to warning circuit, can use.
As shown in Figure 2, as different from Example 1, do not establish horizontal cut on the supporting seat 1.Compare embodiment 1, it has the advantage of being convenient to make simple in structure, but when mounted, must earlier tube for transfusion be pulled up from transfusion pipkin or infusion bottle, is connected with transfusion pipkin or infusion bottle after waiting to penetrate the center hole of supporting seat 1, this point is not so good as embodiment 1 convenience again.
Narrate operation principle of the present utility model below.
Be illustrated in figure 3 as transfusion in the pipkin 5 during no medicinal liquid, the refraction situation of the light generation that luminous tube sends.The light that luminous tube sends does not reflect when passing air substantially, only when penetrating and passing transfusion pipkin 5, reflect, because incident is identical with shooting angle, thereby the relative installation relation of pressing the luminous tube and the receiving tube of diagram photoswitch, receiving tube can be received the light that luminous tube sends.The signal (photocell connection) that this moment, photoswitch produced should be represented to infuse does not have medicinal liquid in the pipkin.
Be illustrated in figure 4 as when in the transfusion pipkin 5 medicinal liquid being arranged the refraction situation that the light that luminous tube sends produces.The light that luminous tube sends has produced the very refraction of wide-angle when passing medicinal liquid after penetrating transfusion pipkin 5, thereby concern that by the luminous tube of diagram photoswitch and the relative installation of receiving tube receiving tube can not receive the light that luminous tube sends.The signal (photocell shutoff) that this moment, photoswitch produced should be represented to infuse has medicinal liquid in the pipkin.
The generation of above-mentioned situation all is significantly smaller than the density of medicinal liquid because of the density of air, and the luminous tube of photoswitch 2 departs to the straight line between the receiving tube due to the radial line of circular hole.Here can find out also that the color of it and medicinal liquid is irrelevant.
In addition, can establish bead 3 in the inwall upper edge of the circular hole of supporting seat, supporting seat just can be stuck on the top of transfusion pipkin like this, thus make install and use all very convenient.
Need to prove, if change the relative installation relation of luminous tube and receiving tube, for example, keep the luminous tube invariant position and receiving tube is placed on the position of beam projecting transfusion pipkin shown in Figure 4, then the on-state of photoswitch and off state also can be represented respectively to infuse has medicinal liquid and no medicinal liquid in the pipkin.
