Description
Technical field
This utility model relates to hemodialysis field, relates in particular to a kind of hemodialysis tube.
Background technology
Hemodialysis is one of acute or chronic renal failure kidneys of patients Replacement Therapy.It is by being drained to external by body inner blood, through one by the dialyser forming without several hollow fibres in, blood to containing the similar electrolyte solution (dialysis solution) of body concentration inside and outside hollow fibre one by one, carry out mass exchange by disperse, convection current, remove metabolic waste in body, maintain electrolyte and acid-base balance; Remove too much moisture in body simultaneously.
At present, the Dialysis tubing using in dialysis procedure only has dialysis simple function, can not regulate velocity of blood flow, in the time that obstruction or other unusual conditions occur Dialysis tubing, can not find in time, can bring great risk.And in patient body, often there is chronic inflammatory reaction situation, inflammatory reaction is the risk factor that causes death, inflammatory reaction is mainly that vascular access infection, dialysis solution pollution, time leakage etc. cause, extensively adopt clinically ultraviolet radiation therapy to treat, and traditional ultraviolet radiation therapy troublesome poeration, and easily occur pollution, blood coagulation, bubble etc., therapeutic effect is not good.
Utility model content
For the deficiencies in the prior art, this utility model provides a kind of hemodialysis tube, and this hemodialysis tube prevents body distortion by pressure transducer, and monitoring body internal pressure is also passed through the aperture of control device flow automatic regulation actuator, make blood circulation smooth and easy, thereby reduce medical-risk.
A kind of hemodialysis tube, comprise body, body is provided with flow regulator, the below of flow regulator is provided with annular pressure transducer, the inwall of body offers cannelure, pressure transducer is positioned at cannelure, is connected with the control device that regulates described flow regulator aperture according to the signal of described pressure transducer on flow regulator.
Preferably, on pressure transducer, be connected with alarm.
Preferably, the lower end of body is provided with spiral quartz ampoule, and body is connected by tube for transfusion with quartz ampoule.
Preferably, also comprise columniform heater, quartz ampoule hovers above the side of heater.
Preferably, the side opening of heater is provided with the groove matching with quartz ampoule, and quartz ampoule spirals in groove.
Preferably, heater is provided with locking device, and locking device locks quartz ampoule.
Compared with prior art, the utlity model has following beneficial effect: the utility model discloses a kind of hemodialysis tube and comprise body, body is provided with flow regulator, the below of flow regulator is provided with annular pressure transducer, the inwall of body offers cannelure, pressure transducer is positioned at cannelure, is connected with the control device that regulates described flow regulator aperture according to the signal of described pressure transducer on flow regulator.Hemodialysis tube of the present utility model prevents body distortion by pressure transducer, monitoring body internal pressure, can find in time that Dialysis tubing blood flow is not smooth or other are abnormal, and by the aperture of control device flow automatic regulation actuator, regulate blood flow, make blood flow unimpeded, convenient and swift, and reduce medical-risk.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Accompanying drawing indicates as follows: 1-body, 2-tube for transfusion, 3-quartz ampoule, 4-heater, 5-locking device, 6-pressure transducer.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in detail.
Referring to Fig. 1, a kind of hemodialysis tube of the present embodiment, comprise body 1, body 1 is provided with flow regulator, the below of flow regulator is provided with annular pressure transducer 6, the inwall of body 1 offers cannelure, and pressure transducer 6 is positioned at cannelure, is connected with the control device that regulates described flow regulator aperture according to the signal of described pressure transducer 6 on flow regulator.The hemodialysis tube of the present embodiment prevents that by annular pressure transducer 6 body 1 is out of shape, and accurate, Real-Time Monitoring body 1 internal pressure, when occurring in hemodialysis tube that blood flow is not smooth or other are when abnormal, by the aperture of control device flow automatic regulation actuator, regulate blood flow, thereby blood flow is unimpeded, body 1 internal pressure recovers stable, reduces medical-risk; In the time that serious obstruction appears in hemodialysis tube, the pressure that pressure transducer 6 detects strengthens lastingly, and flow regulator is closed in control device control, and alarm equipment alarm reminds medical worker to process.Control device in the present embodiment can be circuit board, does not relate to software program.
Preferably, the lower end of body 1 is provided with spiral quartz ampoule 3, and body 1 is connected by tube for transfusion 2 with quartz ampoule 3.In the time that needs carry out ultraviolet irradiation treatment, by tube for transfusion 2, body 1 is connected with quartz ampoule 3, then irradiate with ultraviolet, because quartz ampoule 3 is spiral type, make irradiated area larger, avoid occurring the situation such as blood contamination, blood coagulation, easy to use, therapeutic effect is obvious.
Preferably, also comprise columniform heater 4, quartz ampoule 3 hovers above the side of heater 4.Particularly cold season, in hemodialysis tube, blood heat is lower, when patient directly carries out hemodialysis, can not feel well, by heater 4, blood is heated, blood and human body in hemodialysis tube are adapted, eliminate sense of discomfort, quartz ampoule 3 spirals and makes quartz ampoule 3 inner blood heating surface (area) (HSs larger with the side of heater 4.
Preferably, the side opening of heater 4 is provided with the groove matching with quartz ampoule 3, and quartz ampoule 3 spirals in groove, and heater 4 is provided with locking device 5, and locking device 5 locks quartz ampoule 3.Quartz ampoule 3 spirals in groove, makes quartz ampoule 3 larger with the contact area of heater 4, is conducive to quartz ampoule 3 and is heated, moreover be conducive to protect quartz ampoule 3, and locking device 5 locks, fixes quartz ampoule 3.
Applicant's statement, this utility model illustrates detailed structure of the present utility model and technique by above-described embodiment, but this utility model is not limited to above-mentioned detailed structure and technique, do not mean that this utility model must rely on above-mentioned detailed structure and technique could be implemented.Person of ordinary skill in the field should be understood that; to any improvement of the present utility model; the selections of the equivalence replacement to the each raw material of this utility model product and the interpolation of auxiliary element, concrete mode etc., within all dropping on protection domain of the present utility model and open scope.
