Abstract
A medical contrast medium electric pusher consists of a casing (1), a screw (2), a push plate (3), a speed regulation motor (M) and a control circuit; the two ends of the screw (2) are arranged on the casing (1), the power shaft of the speed regulation motor (M) is connected with one end of the screw (2), and the push plate (3) is arranged on the screw (2) through threads; the control circuit consists of a remote switch (K1), a three-pin plug (CP1), a three-pin plug gang switch (K2), a proximity switch (K3), a motor positive and negative rotation switch (K4), a forward limit switch (K5), a backward limit switch (K6), and diodes (D1, D2). The medical contrast medium electric pusher has the advantages of realizing remote bolus of the contrast medium, protecting medical personnel against X-ray radiation exposure, and ensuring the health of the medical personnel.
Description
Technical field
This utility model relates to medical instruments field.
Background technology
At present, hospital carries out Salpingography when checking with X-ray machine to the patient of sterility and infertility, needs contrast agent is injected in patient's body with the hand propelled syringe by the side of the patient by the medical worker, passes through the inspection of X-ray machine film viewing screen while injecting.This mode of injecting is under the x-ray bombardment medical worker all the time, so can damage injecting the medical worker for a long time.
Summary of the invention
The purpose of this utility model is exactly contrast agent to be injected in patient's body with the hand propelled syringe at existing, and this mode of injecting is under the x-ray bombardment medical worker all the time, for a long time so can be to injecting the deficiency that the medical worker damages.
This utility model is made up of housing 1, screw rod 2, push pedal 3, buncher M and control circuit; Screw rod 2 two ends are installed on the housing 1, and the line shaft of buncher M links to each other with screw rod 2 one ends, and push pedal 3 is contained on the screw rod 2 by screw thread; Control circuit by remote switch K1, three-prong plug CP1, three-prong plug gang switch K2, proximity switch K3, motor positive and inverse K switch 4, the limit switch K5 that advances, retreat limit switch K6, diode D1, D2 form; Two terminals of buncher M connect respectively and advance limit switch K5 and retreat limit switch K6, the limit switch K5 that advances is in parallel with diode D1, it is in parallel with diode D2 to retreat limit switch K6, motor positive and inverse K switch 4 is made up of two single-pole double-throw switch (SPDT)s, the common port of each single-pole double-throw switch (SPDT) meets the limit switch K5 and retreat limit switch K6 of advancing respectively, and limit switch K5 and retreating on the housing 1 that limit switch K6 is installed in push pedal 3 both sides respectively advances; The public termination motor positive and inverse K switch 4 of proximity switch K3, the common port of remote switch K1 connects positive source by three-prong plug CP1, and the two ends of three-prong plug gang switch K2 meet power supply and three-prong plug CP1 respectively.
The utility model has the advantages that: can realize the long-range contrast agent of injecting by this utility model, avoid the medical worker to be subjected to x-ray bombardment, guarantee that the medical worker's is healthy.
Description of drawings
Accompanying drawing 1 is this utility model structural representation.Accompanying drawing 1 is this utility model circuit diagram.
The specific embodiment
The screw rod two ends are installed on the housing, and the line shaft of buncher (15V direct current) links to each other with screw rod one end, and push pedal is contained on the screw rod by screw thread; Two terminals of buncher connect respectively and advance limit switch and retreat limit switch, limit switch and retreating on the housing that limit switch is installed in the push pedal both sides respectively advances, the driven by motor screw rod rotates, the promotion push pedal is advanced or is retreated into when limiting the position, advance limit switch or move back limit switch work makes the motor stall.Limit switch is in parallel with diode D1, the afterflow path when retreating as motor.It is in parallel with diode D2 to retreat limit switch, the afterflow path when advancing as motor.The motor positive and inverse switch is made up of two single-pole double-throw switch (SPDT)s, and the common port of each single-pole double-throw switch (SPDT) connects respectively and advances limit switch and retreat limit switch; Another termination power.Far, process control is finished by remote switch, two single-pole double-throw switch (SPDT)s of proximity switch and three-prong plug and gang switch; The public termination motor positive and inverse switch of proximity switch, the common port of remote switch connects positive source by three-prong plug, and the two ends of three-prong plug gang switch connect power supply and three-prong plug respectively.After pulling up three-prong plug, three-prong plug gang switch closure, this moment, proximity switch was realized short range control to this injector.After plugging three-prong plug, the three-prong plug gang switch disconnects, and this moment, remote switch and proximity switch can be realized short range control to this injector.
During use, contrast medium injector 4 is placed on the housing, the push rod of contrast medium injector 4 is against in the push pedal and gets final product.
