Description

Trochar

Technical field

The utility model is related to a kind of medicine equipment, more particularly to a kind of trochar.

Background technology

Trochar is a kind of common medicine equipment, and it is punctured using draw point, and draw point is pierced into patient together with sleeve pipe In vivo, then extract draw point out, be only that sleeve pipe is retained in patient vessel, therefore will not occur to cause due to patient motion The situation that blood vessel is pierced through by needle point, it is adaptable to the long-term situation that syringe needle is retained to progress long-term infusion in the blood vessel.Trochar The problem of be, every time transfusion interruption or terminate after, it is necessary in trochar inject heparin solution carry out tube sealing, otherwise blood flow back The phenomenon that resulted in blockage in sleeve pipe can be condensed in.

As shown in figure 12, the joint below figure is divided into two joints to the trochar of prior art, and a joint is used for The dosing in infusion process a, joint is used to infuse.If necessary to injection heparin solution tube sealing, it is necessary to first by infusion connector Liquid pull up, then by syringe inject heparin solution, this method for a bottle liquid medicine infuse terminate situation also compare Relatively rationally, but for transfusion tempus intercalare, such as patient needs pause transfusion then being infused after going to conduct a survey and checking out Situation (patient check when be to be carried out together with the liquid of transfusion, transfusion liquid is hung on movable stand for transfusion), then can It is cumbersome, pull up woven hose and carry out plugging woven hose again after the completion of tube sealing, tube sealing, woven hose is pulled up in transfusion midway then in addition Woven hose is plugged again, adds the contaminated chance of decoction.

Utility model content

In view of the above problems, the utility model proposes a kind of trochar, it carries tube-sealing solution, need not be pulled out in the transfusion intermittent phase Lower woven hose carries out tube sealing.

Trochar of the present utility model, it includes connector portions, and connector portions include dosing connector, infusion connector；The joint Portion further comprises tube sealing joint；

Tube sealing joint is formed as body, and tubular body space is formed as the first space of cylinder and the second sky of cylinder Between, the first space is connected with second space, and the diameter in the first space is less than second space；First space and the output of infusion connector End connection；Longitudinal guide is formed with the lower end of the body corresponding to second space, is formed at least in longitudinal guide side One horizontal shift slot；Longitudinal guide is connected with horizontal shift slot.

Second space, which is hermetically accommodated, to be accommodated in the plug of cylinder, the space that plug is limited together with body for sealing The heparin solution of pipe described sleeve pipe pin；Handle is formed with the outside of plug；Handle stretches out from the longitudinal guide, by promoting Moved with rotary plug in second space, handle is optionally trapped in the horizontal shift slot；

Be formed with valvular valve in first space, by the output end in the first space and infusion connector selectively communicate with or every It is disconnected.

Preferably, the horizontal shift slot is two.

Preferably, the horizontal shift slot further comprises recess, for handle described in clamping.

Contained because trochar of the present utility model is further comprised on its joint in tube sealing joint, tube sealing joint The tube-sealing solution of heparin solution composition is, it is necessary to when interrupting transfusion and carrying out outgoing check, it is only necessary to one gear of driving handle, you can will The tube-sealing solution of respective amount is sent into the sleeve pipe of trochar via the output end of second space and infusion connector and carries out tube sealing, it is to avoid blood Liquid backflow condenses plugging, and without woven hose is pulled up, easy to operate avoid when existing trochar plugs woven hose may lead The introducing of the pollution of cause.

Embodiment

Below, it is described in detail with reference to Fig. 1-11 pairs of trochars of the present utility model.

Trochar of the present utility model, it includes needle section 10, connecting tube 20, connector portions 30, and connector portions 30 include dosing Joint, infusion connector and tube sealing joint 40.

Tube sealing joint 40 is formed as body, tubular body space be formed as cylinder the first space 45 and cylinder the Two spaces 44, the first space 45 is connected with second space 44, and the diameter in the first space 45 is less than second space 44；First space 45 Connected with the output end of infusion connector, be eventually leading to connecting tube 20.It is formed with the lower end of the body corresponding to second space 44 Longitudinal guide 41, at least one horizontal shift slot 42, longitudinal guide 41 and horizontal shift slot 42 are formed in longitudinal guide 41 sideways Connection.

Second space 44 hermetically accommodates the plug 47 of cylinder, that is to say, that a part for plug 47 is inserted into vertical all the time Into the second space 44 on the top of guide groove 41.Accommodated in the space that plug 47 is limited together with body for tube sealing trochar Heparin solution.

The outside of plug 47 is formed with handle 48；Handle 48 stretches out from longitudinal guide 41, passes through promotion and rotary plug 47 are moved in second space, and handle 48 is optionally trapped in horizontal shift slot 42.

Valvular valve 46 is formed with first space 45, the first space 45 and the output end of infusion connector are optionally connected Logical or cut-off.

Horizontal shift slot 42 is two.

Horizontal shift slot 42 further comprises recess 43, for firmly clamping handle 48.

Before use, handle is in position as shown in Figure 2, now valvular valve is in Fig. 5 and Fig. 7 shown state.When need When temporarily interrupting transfusion, driving handle forward, now valvular valve be in state as shown in Figure 6 and Figure 8, heparin solution is noted Enter into trochar, reach rotary handle after horizontal shift slot, be held in horizontal shift slot or in recess, due to stopping Driving handle, after external pressure is removed, valvular valve returns to Fig. 5 and Fig. 7 shown state, and second space is separated.

The amount of heparin solution required for one gear tube sealing of correspondence, generally 5 milliliters.

When with multiple gears, trochar of the present utility model can repeatedly interrupt transfusion tube sealing.

In order to portable, tube-sealing solution should not be injected in tube sealing joint too much, that is to say, that the tube sealing after the completion of transfusion, most Carried out well or by infusion connector using syringe, as in the prior art.
