Description

A kind ofly be used for the utensil that medical science radiography compartment maneuver is injected contrast agent

Technical field

This utility model relates to medical apparatus and instruments, particularly a kind ofly is used for the utensil that medical science radiography compartment maneuver is injected contrast agent.

Background technology

The method that many medical science contrast examination projects need adopt maneuver to inject contrast agent is implemented, as hysterosalpingography, angiography, the CT enhanced ct scans, urinary tract retrograde urography etc., up to now, the maneuver method of injecting contrast agent has following mode and drawback clinically: the first is injected implementing maneuver with the patient under with the situation of chamber by the medical worker, the medical worker is exposed under the roentgen radiation x, be subject to radiation injury, dress heavy radiation protection apparatus as the medical worker, then make its operation inconvenience or uncomfortable, no matter whether the medical worker protects, the drawback that can not Real Time Observation when all existing in maneuver and inject contrast agent enters patient's physiological disposition to contrast agent; It two is to implement maneuver by patient oneself under medical worker's indication to inject, because contrast agent injects in the body often with the pain discomfort, the patient does not have maneuver and injects experience in addition, exists patient Chang Buneng on dynamics of injecting and speed to meet the drawback of medical requirement well thus.It is above-mentioned that both all have a strong impact on the quality of contrast examination.In addition, the application of injecting instrument for the contrast agent of medical science contrast examination is automatically still arranged, this quasi-instrument injects contrast agent automatically by preestablishing injection pressure and/or speed, there is and eliminated application and the performance that medical worker's maneuver is injected contrast agent experience and skill etc., this drawback also has a strong impact on the quality of contrast examination.

The utility model content

The purpose of this utility model is intended to overcome above-mentioned drawback of the prior art, provides a kind of compartment maneuver that helps promoting medical worker's radioactivity protection and significantly improve the contrast examination quality to inject the utensil of contrast agent.

The purpose of this utility model is achieved in that and originally is used for the utensil that medical science radiography compartment maneuver is injected contrast agent, comprise the syringe fixed card slot, the hydraulic drive flexible pipe, syringe, handle and hydralic pressure gauge, it is characterized in that syringe is provided with 3, No. 1 syringe and No. 2 syringes are the mode of relative contact and the mode of the vertical geometrical axis of two syringes on same straight line are placed in the syringe fixed card slot with piston push rod rear end separately, the syringe handle of No. 1 syringe and No. 2 syringes is fixed by symmetrically arranged bayonet socket on the cell wall of syringe fixed card slot both sides respectively, the needle holder of No. 2 syringes is communicated with an end of hydraulic drive flexible pipe, offer the hydralic pressure gauge caulking groove in the handle, three-way pipeline and syringe pipe, hydralic pressure gauge is embedded in the hydralic pressure gauge caulking groove, the preceding pipeline of three-way pipeline is communicated with the other end of hydraulic drive flexible pipe, hydralic pressure gauge in the last pipeline of three-way pipeline and the hydralic pressure gauge caulking groove is communicated with, the back pipeline of three-way pipeline is communicated with the front end of syringe pipe, the rear end of syringe pipe is open, and the syringe pipe supplies the syringe reversibility of No. 3 syringes to be inserted in it whole or in part and the needle holder of No. 3 syringes is communicated with the back pipeline of three-way pipeline; Described handle is drawn materials and is transparent rigid plastics material; Described hydralic pressure gauge can be set to the mechanical type hydraulic table, also can be set to contain or do not contain the electronic type hydralic pressure gauge of data-out port.

This utility model accessory manipulation is injected the principle of contrast agent:

No. 2 is to be the relative mode that contacts and the mode of the vertical geometrical axis of two syringes on same straight line is placed in the syringe fixed card slot with separately piston push rod rear end with No. 1 syringe, and the syringe handle holding of this two syringe is fixed on the bayonet socket on the cell wall of syringe fixed card slot both sides, the relative position relation of No. 2 and No. 1 syringe syringes is fixed, when maneuver promotes the piston push rod of No. 3 syringes, be filled in the aforementioned maneuver of liquid transfer thrust to 2 syringe in the hydraulic drive flexible pipe, pressure promotes the piston push rod of No. 2 syringes and No. 1 syringe successively and does with respect to the motion of syringe separately, at 3 syringes selecting for use is under the condition of same model, because liquid has hardly can compressed physical characteristic, the promotion pressure of liquid transfer maneuver in the hydraulic drive flexible pipe, the piston push rod of 3 syringes can be done relative to almost synchronous the moving of syringe separately.Hydralic pressure gauge is set injects pressure to medical worker's demonstration in real time of operation, avoid unreasonable or unsafe operation of injecting, under the condition of selecting the electronic type hydralic pressure gauge that contains data-out port for use, can be connected with the external computer equipment that is loaded with corresponding demonstration and storing software, reach demonstration, record thus and print the pressure delta data and the curve image of injecting in the contrast agent process.

This utility model accessory manipulation is injected the beneficial effect of contrast agent:

1, because the setting of the hydraulic drive flexible pipe of certain-length, can will place No. 3 syringes of handle one end to be placed in the observation ward in contrast examination place, and will be placed in and No. 1 syringe is placed in the residing radioscopy of the patient instrument room in the syringe fixed card slot No. 2, make No. 1 syringe extract an amount of contrast agent, and make its needle holder and insert the intravital contrast-medium injection pipe of patient and be connected, the medical worker controls the injection of No. 1 syringe interimage agent by the motion of No. 3 syringe piston push rods of manipulation, realize that thus medical worker's maneuver injects the compartment operation of contrast agent, significantly help its radioactivity protection.

2, because the pressure loss of hydraulic pressure in hydraulic drive flexible pipe and No. 2 syringes is small, at 3 syringes selecting for use is under the condition of same model, the medical worker injects No. 3 syringes and directly injects No. 1 syringe and sensuously almost be equal in manual controls such as dynamics and speed, and help it did not thus have the experience of directly injecting contrast agent under this utility model intervention condition and the performance of skill in the past.

3, this utility model is got involved contrast examination, makes the medical worker implement contrast agent bolus under Real Time Observation is had an X-rayed the condition of the dynamic image on the display screen, helps improving the quality of contrast examination, also helps holding better the opportunity of radiography film making.

4, this utility model is got involved contrast examination, has avoided patient oneself to implement inhuman, irrational operator scheme that maneuver is injected under medical worker's indication.
