Abstract
A kind of blood purification blood coagulation alarm is the utility model is related to, belongs to field of medical products.Blood purification blood coagulation alarm of the present utility model, including probe and alarm unit, the probe include light source, photo resistance and geometrical clamp；The alarm unit includes power supply, switch, power supply indicator and power-off alarm.Probe is fixed on dialysis pipeline.When the pachyemia in pipeline of dialysing is to a certain extent or during blood coagulation after hair, the intensity that illumination that light source is sent is mapped in photo resistance is reduced, and the rise of photo resistance resistance value, power-off alarm Circuit Interrupt, sends alarm.Patient and staff's timely processing are reminded, adds the security of blood purification treatment.
Description
Technical field
Field of medical products is the utility model is related to, more particularly to a kind of blood purification blood coagulation alarm.
Background technology
Blood purification treatment is the critical treatment method of uremic patient and rescue part critical illness.Principle is to draw blood
The dialysis pipeline through being made up of arterial blood line pipe, dialyzer and vein blood vessel is fed back in vivo after going out in vitro, in dialyzer,
Dialyzate outside blood and hollow fibre in dialyzer hollow fibers carries out mass exchange to reach therapeutic effect.Follow in vitro
During ring, for some reason, such as No heparinization HD therapy, high blood coagulation state, anti-coagulants dosage deficiency, the relatively low original of CBF
Blood coagulation occurs in dialysis pipeline because blood may occur, discarded blood, replacing dialyzer and pipeline can be caused when serious, is increased
Add blood purification cost, also bring harmful effect to patient.
Blood cleaning equipment such as haemodialysis control unit, blood filter, CRRT at present（Continuous renal replacement therapy）Machine etc. is main
Alarm to dialyzer intravascular coagulation is realized by the change of angiosthenia and vein pressure：When there is blood coagulation in dialyzer, angiosthenia is just
It can raise, vein pressure will decline, and machine can automatic alarm.The method is to judge blood status indirectly to be alarmed.But work as
Blood flow slows down but blood coagulation does not occur, though or the vein pressure of the elevated angiosthenia of blood coagulation or reduction occurs still in machine setting
Normal range (NR) in when, it is possible to fail to report.
Utility model content
In order to solve the above-mentioned technical problem, the purpose of this utility model is to provide a kind of blood purification blood coagulation alarm,
Directly directly monitoring dialysis pipeline in blood status, when pachyemia to a certain extent or occur blood coagulation when energy and alarm.
To achieve the above object, the utility model proposes a kind of blood purification blood coagulation alarm, including list of popping one's head in and alarm
Member, the probe include light source, photo resistance and geometrical clamp；The alarm unit includes power supply, switch, power supply indicator and broken
Electric alarms based on pattern recognition；The fixation accompanies two can be with the intermediate plate of folding, and the light source and photo resistance are respectively placed in two intermediate plates
Relative position, two intermediate plates form the hole to match with dialysis pipeline after closing, two intermediate plates, which are provided with, presses button, is easy to visit
Head is fixed on dialysis pipeline.The power-off alarm is parallel with one another with light source, power supply indicator again after being connected with photo resistance；
Switch is arranged on power cathode side.
The light source can launch visible ray, infrared ray or ultraviolet.
The photo resistance resistance value increases and reduced with intensity of illumination, and its spectrum is consistent with light source light spectrum.
Preferably, the light source infrarede emitting diode.
Preferably, the photo resistance is infrared photoresistor, and resistance value is reduced with the increase of intensity of illumination.
Preferably, two intermediate plate both ends of geometrical clamp have by button.
Preferably, the power supply is D.C. regulated power supply that is chargeable, being connected with AC power.
Compared with prior art, the beneficial effects of the utility model are：By directly monitoring blood status in dialysis pipeline
Blood coagulation alarm is carried out, simple in construction, cost is relatively low, is easily installed and safeguards.
Brief description of the drawings
Fig. 1 is blood purification blood coagulation alarm arrangement schematic diagram of the present utility model.
Fig. 2 is blood purification blood coagulation alarm sonde configuration schematic diagram of the present utility model.
Label declaration：1- is switched, 2- power supplys, 3- power supply indicators, 4- power-off alarms, 5- light sources, 6- photo resistance, 7-
Dialysis pipeline, 8- geometrical clamps, 9- press button.
Embodiment
The utility model is further described below in conjunction with specific embodiment.
As shown in Figure 1 and 2：The blood purification blood coagulation alarm of the present embodiment, including probe and alarm unit, the probe
Including light source 5, photo resistance 6 and geometrical clamp 8；Geometrical clamp, which includes two, to be divided with the intermediate plate of folding, light source 5 and photo resistance 6
The relative position not being placed on the inside of two intermediate plates, two intermediate plate both ends have by button 9, and two intermediate plates are formed after closing and dialysis tubing
The hole that road matches.Alarm unit includes power supply 2, switch 1, power supply indicator 3 and power-off alarm 4, power-off alarm 4 and light
Quick resistance 6 is parallel with one another with light source 5 and power supply indicator 3 again after connecting.
When being monitored to dialysis pipeline 7, probe is fixed on dialysis pipeline with geometrical clamp 8, two intermediate plates are placed in
Dialysis pipeline 7 both sides, button 9 is pressed by tight, light source 5 and photo resistance 6 are in the dialysis both sides relative position of pipeline 7, closure switch
1, power supply indicator 3 is bright, and the light that light source 5 is sent is by the blood illuminator in pipeline 7 of dialysing in offside photo resistance 6.When saturating
The analysis blood flow of pipeline 7 is unobstructed, and relatively large through the intensity of illumination of blood, the resistance of photo resistance 6 is low, and power-off alarm, which is in, closes
State；When dialyse pipeline 7 in pachyemia to a certain extent or occur blood coagulation when, absorption of the blood to light is bright when unobstructed compared with blood flow
Aobvious increase, through dialysis pipeline 7 intensity of illumination it is unobstructed compared with blood flow when decline, the resistance value rise of photo resistance 6, work as resistance value
When being increased to certain limit, Circuit Interrupt, triggering power-off alarm 4 sends alarm, reminds staff's timely processing.
When probe is arranged on the dialyzer in dialysis pipeline, the dialyzer fixture of blood purification machine can also be made
For geometrical clamp, the light source 5 of probe and photo resistance 6 are separately positioned on the inner side of blood purification machine dialyzer two intermediate plates of fixture
Relative position, alarm unit are incorporated into blood purification machine and are monitored.
Most preferred embodiment of the present utility model has illustrated, and the explanation of above example is only for help and understands that this practicality is new
Type, rather than whole embodiments, the various unsubstantialities made for the ordinary skill people of this area using this design are improved,
Or by it is of the present utility model design and technical scheme be directly used in other occasions, the scope of protection of the utility model it
It is interior.
