Abstract
The invention provides a buoyancy-type drip warning sensor and a pressure-type drip warning sensor, which are both simply designed and manufactured, respectively cost only a few cents, are both easy for batch production and can obtain higher benefits after entering the market. The drip warning sensor is high in reliability, avoids false alarm and no alarm, can be mounted in an infusion bag or a stilligout, or on a bypass designed on the stilligout, and can also be manufactured into a whole with other infusion equipment, thereby having an extremely wide development field and an extensive application prospect.
Description
Technical field
The present invention relates to a kind of floatage-type drop alarm sensor and a kind of pressure type drop alarm sensor, belong to the medical equipment design field.
Background technology
Patient is in infusion process; often feel sleepy easily and fall asleep; can not constantly stare at dropping bottle; and doctor or nurse are because the patient who looks after often can not pay close attention to same patient constantly; therefore after the drop in the dropping bottle has been beaten; if nobody in time finds; will enter a lot of air with pathogenic bacteria in the tube for transfusion; even these enter the air that carries the germs of a disease in the tube for transfusion and can enter and cause damage to patient body in the patient body; therefore there is at present multiple drop alarm device; its effect is in time to have reminded medical personnel and patient when drop has been beaten, and the guarantee point dropping liquid is in time changed or infused in time to be stopped, with the protection patient.
In design, make in the process of infusion alarm, most important is exactly invention or design safety, effective, reliable, cheap drop alarm sensor.At present in the patented product about infusion alarm, its drop alarm sensor uses photoelectric sensor basically, but because it is different with transparency to put the dropping liquid color, the environment of in addition infusing is larger to the performance impact of normal optical electric transducer, therefore use the drop alarm device of the drop alarm sensor of photoelectric sensor conduct, photoelectric sensor is had relatively high expectations, so the sensor of this class drop alarm device or performance are bad, or cost is too high.In addition, also have some patented products about drop alarm device, it adopts device that spring-like claims as sensor, because the dropping bottle specification is different, so this type of drop alarm sensor performance has certain limitation.
Summary of the invention
For the problems referred to above, utilize cleverly the some dropping liquid to have designed a kind of floatage-type drop alarm sensor and a kind of pressure type drop alarm sensor to being immersed in buoyancy or these characteristics of pressure that its internal objects produces in the design process of the present invention, the two have simple in structure, Design and manufacture easily, the characteristics of dependable performance, the two cost of while is several sharing money only, but result of use is good.
Solving technical scheme one of the present invention is: a kind of floatage-type drop alarm sensor, and it mainly is comprised of ball float, stay cord, shell, a contact, No. two contacts, elastica, binding posts; Its housing is cylindrical, its inner hollow, and simultaneously, a contact is installed in the bottom of its inside; Shell upper seals with elastica, and the elastica below is fixed wtih the contact No. two; State is kept in touch in a contact and No. two contacts in the situation that is not subjected to external force, the two is connected by two binding posts of wire with the outside respectively, and two binding posts are connected to the signal that external circuit provides a dropping liquid whether to be totally lost for external circuit; Elastica top is by stay cord and the small floating ball connection of top of iting.
Technical scheme one described stay cord can be any material manufacture, and only in order to connect elastica and ball float, therefore for transducer sensitivity, its length should design weak point as far as possible, can omit in case of necessity in its effect.
Technical scheme one described a kind of floatage-type drop alarm sensor, it can design enough littlely as required, and it can be installed in the drip bag or in the stilligout, also can in bypass of tube for transfusion design, it be installed in the bypass simultaneously; When a dropping liquid also is not totally lost, a dropping liquid is all arranged in drip bag, stilligout or the bypass, this moment, ball float was pulled upwardly elastica because of the buoyancy meeting of a dropping liquid to its generation, No. two the contact moves upward and a contact separation with elastica, and the external circuit that is connected with binding post will be received the switching signal of a "off"; When a dropping liquid is totally lost, drip liquid level in drip bag, stilligout or the bypass descends gradually, the suffered buoyancy of ball float fades away, elastica is because of self elastic force return, No. two contacts move downward with a contact with elastica and contact, and the external circuit that is connected with binding post will be received the switching signal of " connection "; Whether external circuit can be judged a dropping liquid according to its signal that receives switching signal that is "off" or the switching signal of " connection " and be totally lost.
Solving technical scheme two of the present invention is: a kind of pressure type drop alarm sensor, and it mainly is comprised of shell, a contact, No. two contacts, elastica, binding posts; Its housing is cylindrical, its inner hollow, and simultaneously, a contact is installed in the bottom of its inside; Shell upper seals with elastica, and the elastica below is fixed wtih the contact No. two; No. one the contact can not contact in the situation that is not subjected to external force with No. two contacts, and the two connects with two binding posts of being connected by wire respectively, and two binding posts are connected to the signal that external circuit provides a dropping liquid whether to be totally lost for external circuit.
Technical scheme two described a kind of pressure type drop alarm sensors, it can design enough littlely as required, and it can be installed in the drip bag or in the stilligout, also can in bypass of tube for transfusion design, it be installed in the bypass simultaneously; When a dropping liquid also is not totally lost, a dropping liquid is all arranged in drip bag, stilligout or the bypass, elastica moves down because of the pressure-acting that a dropping liquid produces, No. two contacts move downward with a contact with elastica and contact, and the external circuit that is connected with binding post will be received the switching signal of " connection "; When a dropping liquid is totally lost, drip liquid level in drip bag, stilligout or the bypass descends gradually, the suffered pressure of elastica fades away, elastica returns to initial condition because self elastic force effect moves upward, No. two the contact moves upward and a contact separation with elastica, and the external circuit that is connected with binding post will be received the switching signal of a "off"; External circuit is whether the switching signal of " connection " or the switching signal of "off" can be judged a dropping liquid and be totally lost according to the signal that it receives.
Technical scheme one of the present invention and technical scheme two described elasticas, it can be the certain elastic film of having of rubber or other any material manufacture.
Technical scheme one of the present invention and technical scheme two described external circuits design as required for others skilled in the art; be used for and be connected a kind of floatage-type drop alarm sensor or a kind of pressure type drop alarm sensor connecting; finish in the lump other circuit of warning task, it is not at the protection domain of this patent.
The invention has the beneficial effects as follows: design and manufacture of the present invention is simple, and single cost only needs several sharing money, and easily realizes batch production, and better results after coming into the market; The present invention, reliability is high, can not produce false alarm and does not report to the police; The present invention can be installed in the drip bag or in the stilligout, also can it be installed in the bypass in bypass of stilligout design, and it also can be integrated with other drop device fabrications, so its development field is very big, and utilization has a extensive future.
