Abstract
The utility model discloses a T-shaped valve type three-way indwelling needle for injecting radioactive medicine, and relates to the field of medical auxiliary equipment. The T-shaped valve type three-way indwelling needle is characterized in that an extension tube (11) is arranged on an indwelling needle cannula (12), a valve is arranged at the other end of the extension tube (11) and comprises a connector (4), a connecting tube (1) and a control handle, the connecting tube (1) and the connector (4) are of integrated structures, the connecting tube (1) is connected with the extension tube (11), three outlets are formed in the connector (4), a first protective cap (2), a second protective cap (3) and a heparin cap (5) are respectively arranged on the three outlets, and the control handle is arranged on the connector (4). The T-shaped valve type three-way indwelling needle for injecting the radioactive medicine has the advantages that the T-shaped valve type three-way indwelling needle is simple in structure and high in practicality, and medicine which remains in an inner cavity of the indwelling needle can be effectively cleaned; medicine-human contact can be reduced in injection procedures, and accordingly the medication safety can be improved.
Description
[technical field]
This utility model relates to medical auxiliary equipment field, especially relates to a kind of T-shaped valve type three-way remaining needle of injection of radioactive substances.
[background technology]
Known, radionuclide image technology is the important component part of nuclear medicine, inject chemical molecular using radionuclide or its labelling as tracer by vein, application ECT, SPETCT-CT, the detection instrument detectable radionuclides such as PET-CT are at the ray that occurs to emit in the process of nuclear decay, thereby make the diagnosis of disease, but the gamma-rays producing due to these radiopharmaceutical has higher emittance, therefore in injection process, adopting under the prerequisite of good radiation protection measure, to optimize radiopharmaceutic injecting method simultaneously, when requiring safety injection exactly, reduce in syringe and remaining needle radiopharmaceutic residual, guarantee that enough radiopharmaceutical can inject in patient body fully, but in practice process, often there is the residual defect that too much contacts radiopharmaceutical overlong time with staff of syringe and radiopharmaceutical in remaining needle, so, be unfavorable for person under inspection's inspection, also affected greatly medical personnel's personal safety.
[summary of the invention]
In order to overcome the deficiency in background technology, the utility model discloses a kind of T-shaped valve type three-way remaining needle of injection of radioactive substances, this utility model by arranging three outlets on connector, and by the joystick on connector, outlet is controlled, reach abundant injectable drug with this and contact object with reducing a staff.
In order to realize described goal of the invention, this utility model adopts following technical scheme:
A kind of T-shaped valve type three-way remaining needle of injection of radioactive substances, comprise remaining needle, extension tube and valve, remaining needle is by puncture needle, remaining needle sleeve pipe, remaining needle pin cap, batching pig and the pin wing form, in remaining needle pin cap, be provided with puncture needle and batching pig, puncture needle is provided with remaining needle sleeve pipe, on remaining needle sleeve pipe, be provided with extension tube, the other end of extension tube is provided with valve, valve is by connector, connection tube and joystick form, connection tube and connector are structure as a whole, connection tube is connected with extension tube, on connector, be provided with three outlets, in three outlets, be respectively equipped with the first helmet, the second helmet and calparine cap, on connector, be provided with joystick.
Described connector is hollow-core construction, and three outlets of connector are T-shaped structure respectively on connector.
Described extension tube is provided with clip.
Owing to having adopted technique scheme, the utlity model has following beneficial effect:
The T-shaped valve type three-way remaining needle of a kind of injection of radioactive substances described in the utility model, comprise remaining needle, extension tube and valve, by three outlets are set on connector, and by the joystick on connector, outlet is controlled, reach abundant injectable drug with this and contact object with reducing a staff; The T-shaped valve type three-way remaining needle of a kind of injection of radioactive substances described in the utility model, simple in structure and practical, can effectively clear up the medicine that remains in remaining needle inner chamber, and in the process of injection, reduce the artificial contact of medicine, improve the safety of medication.
[brief description of the drawings]
Fig. 1 is structural representation of the present utility model;
In figure: 1, connection tube; 2, the first helmet; 3, the second helmet; 4, connector; 5, calparine cap; 6, clip; 7, puncture backshank; 8, the pin wing; 9, batching pig; 10, puncture needle; 11, extension tube; 12, remaining needle sleeve pipe; 13, remaining needle pin cap.
[detailed description of the invention]
Explanation this utility model that can be detailed by the following examples, open the purpose of this utility model is intended to protect all technological improvements within the scope of this utility model.
The T-shaped valve type three-way remaining needle of a kind of injection of radioactive substances described in 1 by reference to the accompanying drawings, comprise remaining needle, extension tube 11 and valve, remaining needle is by puncture needle 10, remaining needle sleeve pipe 12, remaining needle pin cap 13, batching pig 9 and the pin wing 8 form, in remaining needle pin cap 13, be provided with puncture needle 10 and batching pig 9, puncture needle 10 is provided with remaining needle sleeve pipe 12, on remaining needle sleeve pipe 12, be provided with extension tube 11, the other end of extension tube 11 is provided with valve, valve is by connector 4, connection tube 1 and joystick form, connection tube 1 is structure as a whole with connector 4, connection tube 1 is connected with extension tube 11, on connector 4, be provided with three outlets, in three outlets, be respectively equipped with the first helmet 2, the second helmet 3 and calparine cap 5, on connector 4, be provided with joystick, described connector 4 is hollow-core construction, and three outlets of connector 4 are T-shaped structure respectively on connector 4, described extension tube 11 is provided with clip 6.
Implement the T-shaped valve type three-way remaining needle of a kind of injection of radioactive substances described in the utility model, first make three outlets keep unimpeded by the joystick on connector 4 in use, then the syringe of the outlet of the first helmet 1 access normal saline, connector 4 is rinsed with normal saline, clean the inner chamber of remaining needle through extension tube 11 simultaneously, outlet from calparine cap 5 after cleaning out pours into heparin in remaining needle, then removing remaining needle pin cap 13 with hand-held the pin wing 8 punctures to person under inspection's forearm vein blood vessel again, insert, and can regulate the length of puncture needle 10 in remaining needle sleeve pipe 12 by puncture backshank 7 and batching pig 9, after adjusting to correct position, just can pass through joystick, make the second helmet 3 outlets keep unimpeded with connection tube, exported again with radioactivity syringe and be connected, so just radiopharmaceutical can be exported to injection by the second helmet 3, open calparine cap 5 exports and heparin is poured in remaining needle simultaneously simultaneously, and the first helmet 2 outlets can be injected into normal saline in remaining needle, not only by infusion of medicine person under inspection body, also the radiopharmaceutical remaining in syringe and in remaining needle is rinsed, and clip 6 in extension tube 11 can play good fixation.
This utility model does not describe part in detail for prior art.
