Description
This utility model relates to a kind of tube for transfusion that is used for hospital for patient's transfusion, especially a kind of one-time infusion tube that has automatic temperature control heating device.
Along with improving constantly of rapid development of economy and people's material life, people are more and more higher to the requirement of quality of medical care, and various advanced persons' armarium also constantly is born thereupon.Research to the suitable attemperation of medical transfusion (especially infusion in winter temperature and body temperature differ than conference and cause patient's pain or other multiple discomfort) also progressively is subjected to people's attention, but the tube for transfusion product that does not have pair medicinal liquid to carry out the appropriate heating temperature control at present as yet comes out.Therefore the medical worker is in that patient is carried out infusion treatment, when the patient does not feel well, have to or add a cover simple and crude method such as cotton-wadded quilt and solve with the hot water bag hot compress.
Existing declare the infusion heating device of patent, as Chinese patent ZL95239546.0 infusion heating device, its adopt can folding two semicylinder structures, during use it is enclosed within on the tube for transfusion after separately, the reuse adhesive tape is bonded together two semicircle housings.The defective of this device is: only according to the patient medicinal liquid is felt to come the manual adjustments pressure regulator in the use, thereby the temperature that changes medicinal liquid is to adapt to the patient, therefore need the special messenger to nurse, a carelessness will bring danger when fluid temperature surpasses the human body temperature certain proportion slightly.If dimmed that of patient's mind just more can't use.
The purpose of this utility model is a kind of one-time heating temperature-controlling infusion pipe of design, and it can realize medicinal liquid is heated temperature control, thereby uses safety, convenient.
This utility model comprises two parts: control box and heater.Wherein, AC-DC conversion and potential device and temperature controller are arranged in the control box, power supply indicator, burner on light, on and off switch, thermoregulator and alternating current power supply input lead, dc source output lead and feedback signal lead are arranged on the control box.
Heater of the present utility model mainly comprises the reservoir that is connected on the tube for transfusion and is looped around the heater coil in the reservoir outside and the temperature sensor that is positioned at the reservoir groove that dc source input socket and temperature sensor signal accessory power outlet all are provided with (fixing) on the outer housing of heater.Because a special reservoir of storing medicinal liquid is arranged on the tube for transfusion, when the medicinal liquid in the tube for transfusion constantly flows, the medicinal liquid of instantaneous turnover reservoir only accounts for the very little part of reservoir inner liquid medicine, and is therefore little to the influence of temperature change of reservoir inner liquid medicine, thereby is convenient to control the temperature of medicinal liquid.
When the purpose of this utility model is achieved in that transfusion, at first allow medicinal liquid be full of tube for transfusion, close transfuse switch, connect control box and heater, again the alternating current power supply input lead is connected the 220V alternating current power supply, turn on the power switch, the rotary temperature actuator is set needed temperature, AC-DC conversion and potential device become direct current safe voltage (to human body safely) to alternating current and are added on the heater coil that is looped around the reservoir outside, and medicinal liquid is heated.When fluid temperature arrived the safe temperature range limit of setting, the temperature sensor that is positioned at the reservoir groove will be sent signal to control box at last, and temperature controller is just carried out and stopped the heating action, just can infuse to the patient at this moment.Because the medicinal liquid in the tube for transfusion is mobile, bring in constant renewal in, thereby the temperature of reservoir inner liquid medicine also can slowly descend thereupon, when fluid temperature is reduced under the design temperature in limited time, the temperature sensor that is positioned at the reservoir groove feeds back signal to control box, and temperature controller is just carried out and continued the heating action.Like this, in the infusion process herb liquid remains at the temperature range to human body safety of setting.
Owing to adopt such scheme, this utility model has solved the temperature control problem of heating medicinal liquid preferably, heater and tube for transfusion integrated (heater is fixed on the reservoir outside) have been realized simultaneously, control box and heater be separated the flexible connection of plugs and sockets formula (they by), thereby the utlity model has simple in structure, heats is good, safe in utilization, characteristics easily.
Below in conjunction with drawings and Examples this utility model is further specified.
Fig. 1 is a sketch map of the present utility model.
Fig. 2 is a heater structural representation of the present utility model.
Fig. 3 is a control box structural representation of the present utility model.
As Figure 1-3, a kind of one-time heating temperature-controlling infusion pipe, it is characterized in that: tube for transfusion is provided with a reservoir (5), heater coil (6) is looped around the outside of reservoir (5), temperature sensor (3) is positioned at the groove of reservoir (5), dc source input socket (4) and temperature sensor signal accessory power outlet (2) all are arranged on the outer housing of heater (1), and power supply indicator (10) is housed on the control box (7), burner on light (15), on and off switch (9), thermoregulator (8) and alternating current power supply input lead (16), have the dc source output lead (11) of attaching plug (12) and have the feedback signal lead (14) of Signal plug (13).
During transfusion, close transfuse switch after at first allowing medicinal liquid be full of tube for transfusion, then the attaching plug (12) of dc source output lead (11) and the Signal plug (13) of feedback signal lead (14) are inserted into respectively in dc source input socket (4) and the temperature sensor signal accessory power outlet (2), again alternating current power supply input lead (16) is connected the 220V alternating current power supply, turn on the power switch (9), power supply indicator this moment (10) is bright.Then, rotary temperature actuator (8) is set needed temperature, and burner on light this moment (15) is bright.By AC-DC conversion and the potential device in the control box (7), alternating current becomes the direct current safe voltage and is added on the heater coil (6) that is looped around reservoir (5) outside, and medicinal liquid is heated.At last when fluid temperature arrives the safe temperature range limit of setting, the temperature sensor (3) that is positioned at reservoir (5) groove will be sent signal to control box (7), temperature controller disconnects the power supply of heater (1), stop heating, burner on light (15) extinguishes, and just can infuse to the patient this moment.Because the medicinal liquid in the tube for transfusion is mobile, cause the medicinal liquid in the reservoir (5) also to be brought in constant renewal in, thereby the temperature of reservoir (5) inner liquid medicine also can slowly descend thereupon.Reduce under the range of set temperature in limited time when fluid temperature, temperature sensor (3) is just sent signal and is given control box (7), and temperature controller is connected the power supply of heater (1), continues heating.Like this, in the infusion process herb liquid remains at the safe temperature scope of setting.
