Abstract
The utility model relates to a transfusion control device which comprises a housing body, a transfusion tube clamping device arranged in the housing body, a clamping slot and a controller, wherein the transfusion tube clamping device is composed of a motor, a worm arranged on an output shaft of the motor, a worm wheel and a cam arranged on a shaft of the worm wheel. One side of the lower part of the clamping slot is provided with a luminous tube, and the other side of the lower part of the clamping slot is provided with a photosensitive tube. The luminous tube, the photosensitive tube and the motor are all connected with the controller. The utility model can set and accurately adjust the dropping speed, and solve the problems that the dropping speed is not easy to control.
Description
This utility model belongs to a kind of infusion apparatus, particularly relates to a kind of device of controlling transfusion speed.
Be to adopt the mode of manual adjustments that the switching degree of tube for transfusion is regulated during transfusion at present, drip speed thereby adjust.The randomness of manual adjustments is bigger, drips speed and is difficult to set accurately, causes the trouble that need regulate repeatedly frequently.After the end of instiling, need the manual-lock tube for transfusion, or be nurse on duty in advance, perhaps by nurse on duty once, increased nurse's workload every a period of time inspection.Finish the back owing to carelessness is not in time found if instil, can cause the blood back accident, cause suffering to the patient, even major accident can take place.
The purpose of this utility model provides a kind of can the adjustment automatically and drips speed and can close the control device of tube for transfusion after finishing automatically instiling, to reach speed governing accurately and transfusion safety.
For reaching above-mentioned purpose, this utility model adopts following technical scheme: a kind of transfusion control device, it comprises housing, is contained in the intravital tube for transfusion clamping device of shell, clip slot and controller, the tube for transfusion clamping device by motor, be contained in worm screw, the worm gear on the motor output shaft and the cam that is contained on the worm-wheel shaft is formed, clip slot bottom one side luminous tube is housed, opposite side is equipped with photosensitive tube, and luminous tube, photosensitive tube and motor all are connected with controller.
Controller has the fast initialization circuit of dripping, and initialization circuit is connected with treatment circuit, and the output of photosensitive tube connects treatment circuit, the output termination drive circuit of treatment circuit, and the outfan of drive circuit is connected with motor.
Also being provided with radiating circuit in the above-mentioned controller is connected with treatment circuit.
Because the output of this utility model controller after setting a speed makes machine operation, make tube for transfusion clamped by worm-and-wheel gear and cam, simultaneously because drop changes the luminous intensity of luminous tube through the luminous tube present position time, this variation is received and input processing circuit by photosensitive tube, treatment circuit is counted the blanking time of two adjacent drops and is compared with setting value, when inconsistent, give motor by treatment circuit output corrected signal, motor is rotated to adjust the clamping degree, blanking time until two adjacent drops is identical with setting value, reaches the purpose of accurate control drip velocity.The blanking time that detects last two adjacent drops when treatment circuit greater than the time that sets in advance after, the rotation of controller control motor is clamped tube for transfusion fully, thereby tube for transfusion is closed automatically.Simultaneously treatment circuit makes radiating circuit launch alarm signal, and receiving system can be located at nurse's night shift room, makes nurse on duty make respective handling according to calling out corresponding bed label, can not in time find after having avoided transfusion to finish and the blood back accident takes place.
Further specify this utility model below in conjunction with accompanying drawing and by embodiment:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a control circuit functional-block diagram of the present utility model.
Embodiment: housing 7 is provided with clip slot 18, and the shape of clip slot 18 is consistent with the shape of tube for transfusion and horse Fei Shi pipe 16.The tube for transfusion clamping device is housed in housing 7, forms by motor 8, worm screw 9, worm gear 10 and cam 12,
Worm screw 9 is contained on motor 8 output shafts, and worm gear 10 is contained on the housing 7, and cam 12 is contained on the worm-wheel shaft 11.Manage 16 places at clip slot corresponding to horse Fei Shi, a side is equipped with luminous tube 15, and opposite side is equipped with photosensitive tube 13, changes in order to detect drop 14 logical out of date light intensity.Luminous tube 15, photosensitive tube 13 and motor 8 all are connected by connecting line 6 with controller 17.Controller 17 is provided with and drips speed setting turn-knob 1, on and off switch 2, call button 3, forced deceleration button 4 and force to quicken button 5, and button 4 and 5 is to be provided with for the switching degree of manually adjusting tube for transfusion.As shown in Figure 2, the fast initialization circuit 19 that drips of control circuit is connected with treatment circuit 20, photosensitive tube 13 outfans are connected with treatment circuit 20, treatment circuit 20 outfans are connected with drive circuit 21, drive circuit 21 outfans are connected with motor, treatment circuit 20 also is connected with radiating circuit 22, and power supply 23 is connected to it with foregoing circuit working power is provided.The operation principle of control circuit partly describes in detail in effect.
Only need during transfusion tube for transfusion and horse Fei Shi pipe are put into clip slot, set corresponding speed value according to patient's different situations, opening power 2 gets final product work.
