Summary of the invention
Problem to be solved in the utility model is: provide a kind of structure simple, vacuum magnitude in drainage cylinder can be changed thus conversion drainage speed and improve the Cardiological drainage device of drain precision.
In order to solve the problem, Cardiological drainage device of the present utility model, the interior drainage sleeve comprising external drainage cover and be inserted in external drainage cover, the front end of described external drainage cover is fixed with the drainage tube interface be connected with external drainage cover, described drainage tube interface is connected with drainage tube, the front end of described drainage tube is connected with drainage needle, the front end face of described interior drainage sleeve is provided with an interior draining hole, one is provided with for hiding the rubber lid of interior draining hole in described interior drainage sleeve, described rubber covers and is fixed with a guide post, described guide post to be inserted in interior draining hole and to be inserted into external drainage cover from interior draining hole, two extension springs are also provided with in the inner chamber of described external drainage cover, one end of described extension spring is overlapped with external drainage and is connected, one end is connected with guide post in addition, piston is provided with in described interior drainage sleeve, described piston is fixed with piston rod, the afterbody of described piston rod fixes a handles.
Firm in order to be pressed by drainage needle when drain, Cardiological drainage device of the present utility model, described drainage needle comprises needle stand and is fixed on the syringe needle on needle stand, and described needle stand is provided with the circular hole that two are inserted finger.
Conveniently pull interior drainage sleeve to move forward and backward, Cardiological drainage device of the present utility model, the end of described interior drainage sleeve is fixed with pull bar, and described pull bar is perpendicular to interior drainage sleeve.
The beneficial effect that this utility model obtains is: (1) structure is simple, (2) in time extracting pericardial effusion, first syringe needle is inserted in pericardium, then firmly pull pull bar, under the drive of pull bar, pull interior drainage sleeve to move backward, now form larger negative pressure in drainage sleeve outside, thus the speed of hydrops is extracted, when the hydrops in pericardium is less time, then pull handle, piston rod and piston is driven to move backward by handle, now in interior drainage sleeve, form less negative pressure, thus the speed extracting hydrops is slower, more thoroughly hydrops can be extracted clean, so compared with existing drainage device, Cardiological drainage device of the present utility model, extraction speed can be changed according to the number of hydrops in pericardium, extraction precision is high, extract hydrops more thorough, (3) needle stand is provided with the circular hole that two are inserted finger, when thus extracting hydrops, can extract hydrops on the other hand, and be inserted in circular hole by two fingers on the other hand, it is firm to be pressed by drainage needle, avoids drainage needle to deviate from, (4) end of interior drainage sleeve is fixed with pull bar, and pull bar, perpendicular to interior drainage sleeve, is thus convenient to pull pull bar and drives interior drainage sleeve to move.

Detailed description of the invention
As shown in Figure 1, Cardiological drainage device of the present utility model, the interior drainage sleeve 9 comprising external drainage cover 7 and be inserted in external drainage cover 7, the front end of described external drainage cover 7 is fixed with overlaps 7 drainage tube interface be connected 5 with external drainage, described drainage tube interface 5 is connected with drainage tube 4, the front end of described drainage tube 4 is connected with drainage needle, the front end face of described interior drainage sleeve 9 is provided with an interior draining hole 8, one is provided with for hiding the rubber lid 12 of interior draining hole in described interior drainage sleeve 9, described rubber lid 12 is fixed with a guide post 11, described guide post 11 to be inserted in interior draining hole 8 and to be inserted into external drainage cover 7 from interior draining hole 8, two extension springs 6 are also provided with in the inner chamber of described external drainage cover 7, one end and the external drainage of described extension spring 6 overlap 7 and are connected, one end is connected with guide post 11 in addition, piston 13 is provided with in described interior drainage sleeve 9, described piston 13 is fixed with piston rod 14, the afterbody of described piston rod 14 fixes a handles 10, the syringe needle 1 that described drainage needle comprises needle stand 2 and is fixed on needle stand 2, described needle stand 2 is provided with the circular hole 3 that two are inserted finger, the end of described interior drainage sleeve 9 is fixed with pull bar 15, and described pull bar 15 is perpendicular to interior drainage sleeve 9.
Cardiological drainage device of the present utility model, structure is simple, in time extracting pericardial effusion, first syringe needle 1 is inserted in pericardium, then firmly pull pull bar 15, under the drive of pull bar 15, pull interior drainage sleeve 9 to move backward, now form larger negative pressure in drainage sleeve 7 outside, meanwhile, rubber lid 12 is placed on interior draining hole 8, interior drainage sleeve 9 is in closed state, thus the speed of hydrops is extracted, when the hydrops in pericardium is less time, then pull handle 10, piston rod 14 and piston 13 is driven to move backward by handle 10, now in interior drainage sleeve 9, form less negative pressure, and rubber lid 12 is due to the effect of negative pressure, the pulling force of extension spring 6 can be overcome, interior draining hole 8 is opened, thus the speed extracting hydrops is slower, more thoroughly hydrops can be extracted clean, so compared with existing drainage device, Cardiological drainage device of the present utility model, extraction speed can be changed according to the number of hydrops in pericardium, extraction precision is high, extract hydrops more thorough.
Needle stand 2 is provided with the circular hole 3 that two are inserted finger, when thus extracting hydrops, can extract hydrops on the other hand, and be inserted in circular hole 3 by two fingers on the other hand, it is firm to be pressed by drainage needle, avoids drainage needle to deviate from.
The end of interior drainage sleeve 9 is fixed with pull bar 15, and pull bar 15, perpendicular to interior drainage sleeve 9, is thus convenient to pull pull bar 15 and drives interior drainage sleeve 9 to move.
