Description

Multifunction intravenous infusion telemetering device

This utility model belongs to a kind of medical treatment device that can carry out dynamic telemetry to the venous transfusion process.

When clinically patient being carried out venous transfusion when treatment, need be to normal infusion speed in the infusion process, import whether amount of liquid, liquid are totally lost, syringe needle have clog-free, deviate from, leak outside etc. to observe and handle.Therefore, needing medical personnel ceaselessly to arrive each sick bed limit makes an inspection tour.Its workload is big, especially accompanies under people, transfusion person is many, the nursing staff the is few situation in nothing, is difficult to above-mentioned situation observed in time in detail handle, even brings unnecessary loss to patient.The someone has designed the device that utilizes interior negative pressure variation of infusion bottle and liquid flow to stop to trigger warning for this reason, but this device can not be reported transfusion speed and go into liquid measure.Someone adopts the photovoltaic principals meter to drip, and is equipped with microcomputer system monitoring flow velocity and stops warning, but this device must be equipped with special infusion set, and the cost height is difficult for promoting, and can not uses radio telemetry, does not reach liberation labour force's purpose.

Deficiency in view of said apparatus, the object of the invention is to design a kind of multi-path venous transfusion telemetering equipment that is made of sampler, emitter and receptor, utilize radio telemetry, the staff in night shift room, just can be observed each sick bed transfusion speed, go into liquid measure and have needleless to block, deviate from, leak outside, infuse and situation such as whether finish.Or carry a small-sized receptor, can recognize the transfusion situation of each sick bed within the specific limits at any time, thereby alleviate nursing staff's burden that the liberation labour force increases work efficiency.

This utility model mainly is made of sampling apparatus, emitter and receiving system three parts, and sampling apparatus is formed (as shown in Figure 1) by a special hair Fei Shi dropper and a sampler.Hair Fei Shi dropper (1) is made by hard non-toxic plastic or glass, long 60～80 millimeters, 25～30 millimeters of internal diameters, 0.5～1 millimeter of wall thickness, the one liquid level adjustable pipe (2) that communicates with the external world is arranged on last 1/3 sidewall of hair Fei Shi pipe, 10～15 millimeters of this pipe ranges, two ends internal diameter are 7～10 millimeters, and its lower wall has one " V " type projection.One rubber cap (16) is arranged on the collar extension, and hair Fei Shi pipe and liquid level are regulated in the tube chamber, a horizontal vibrating reed (5).Vibrating reed is made by rustless steel or non-toxic rigid plastic, and long 20～30 millimeters, wide 4～6 millimeters, thick 0.05 millimeter; An end that is positioned at the liquid level adjustable pipe links one (5 * 2 * 2) millimeter Magnet (7); Be positioned at it " V " shape high spot of liquid level adjustable pipe, " V " type bending of direction unanimity is with it arranged.Under the hair Fei Shi dropper 1/3 with the sidewall of liquid level adjustable pipe vertical line on a tubulose circle hole that caves inward is arranged, be that tongue tube is inserted hole (13).Dark 20～25 millimeters of this hole, 4～6 millimeters of diameters.Inserting between hole and the vibrating reed at tongue tube has a magnetic float (10), (10) by the non-toxic plastic cavity and within it the magnetic sheet of portion (11) form.

Sampler is " Contraband " shape, is made up of cabinet (8) and solenoid (9), tongue tube (12) and socket (15).Long 30 millimeters of cabinet, wide 15 millimeters, thick 15 millimeters.(9) be positioned at sampler upper end liquid level and regulate mouth of pipe place, draw a lead to the socket on the hole (6A).(12) be positioned at the sampler lower end, adopt existing small-sized tongue tube, insert (13), draw a lead to the socket on the hole (6B).

Emitter (21) is 50～80 millimeters of length, wide 25～35 millimeters, high 100～150 millimeters radio transmitting apparatus (as shown in Figure 1), one hook (20) is arranged at the top, preceding upper lateral part has a velocity indicator (19), and there is a switch (18) below of (19), and a gauge tap (17) is arranged at the bottom, have one to connect jack (25) in (17) one sides, be connected with sampler by its corresponding connecting pin (22), lead (24) and sampler plug (23).

Emitter (21) internal wiring structure as shown in Figure 2.1 is sampling transducing on-off circuit, with the number of winning the confidence input main circuit handle; 2 is pulse amplifier, voltage-controlled audio oscillator; 3 are transfusion end of a period on-off circuit control emission continuous carrier; 4 are the low-frequency oscillation manipulator; 5 is brilliant control high frequency generator; 6 is the radio match circuit; 7 is power supply.

Receiver as shown in Figure 3, (26) are receiver switch; (27) be green light; (28) be the green light switch; (29) be amber light; (30) be the amber light switch; (31) be red light; (32) be the red light switch; (33) be the transfusion speed key; (34) be the amount of infusion key; (35) be display list; (36) be alarming horn; (37) be antenna.The internal wiring structure of receiver as shown in Figure 4.1 is to put in the radio tuning; 2 are demodulation; 3 amplify and mat closes for amplitude limit; 4 is the amber light indicating circuit; 5 is green light indicating circuit and throughput rate flow velocity circuit; 6 expression measuring circuits; 7 is red light indicating circuit and public warning circuit.

In this utility model work, when drop (4) (see figure 1) falls, even pipe internal vibration sheet (5) vibration, Magnet (7) vibrates simultaneously, make the solenoid (9) in the sampler produce faradic current, import emitter (21) into, send the signal of telecommunication one time by lead, after the radio receiver reception, make the green light flash of light once.When transfusion is obstructed, both do not had the emission of this signal, this moment the amber light switch open, amber light is bright, shows that transfusion blocks.When transfusion leaks outside,, all make green light drip fast display abnormality because liquid drop speed changes.When liquid was totally lost, liquid level descended in the hair Fei Shi pipe, and magnetic sheet (11) is approaching with tongue tube (12), make circuit connection in the tongue tube, import emitter by sampler into through lead and send the persistence signal of telecommunication, after receiving by receptor, make red light bright, send alarm signal simultaneously and report to the police.In infusion process,, can read the per second number of infusion drops by display list (35) by transfusion speed key (33) if need to understand transfusion speed.

Accompanying drawing 1 is sampling apparatus of the present utility model and emitter.(1) hair Fei Shi dropper; (2) liquid level adjustable pipe; (3) hair Fei Shi dropper is suitable for reading; (4) drop; (5) vibrating reed; (6A) hole on the socket; (6B) hole under the socket; (7) Magnet; (8) sampler; (9) solenoid; (10) magnetic float; (11) magnetic sheet; (12) tongue tube; (13) tongue tube is inserted the hole; (14) liquid level; (15) socket; (16) rubber cap; (17) gauge tap; (18) drip fast display switch; (19) drip fast display; (20) hook; (21) emitter; (22) emitter plug; (23) sampler plug; (24) lead; (25) emitter jack; Fig. 2 is the transmitter line block diagram.Fig. 3 is the receptor outline drawing.(26) receptor switch; (27) green light; (28) green light switch; (29) amber light; (30) amber light switch; (31) red light; (32) red light switch; (33) transfusion speed key; (34) amount of infusion key; (35) display list; (36) alarming horn; (37) antenna.Fig. 4 is a receptor circuit block diagram.
