Description
Technical field
This utility model belongs to medical instruments field, particularly a kind of thoracic cavity closed drainage device control valve and this thoracic cavity closed drainage device.
Background technology
Closed drainage of pleural cavity is that thoracic cavity is put in drainage tube one end, and the drainage bottle that other end access is lower than its position, to discharge intrathoracic gas or liquid, lung tissue is opened and restore funcitons again.
During closed drainage of pleural cavity, for ensureing that drainage tube is unobstructed, need to regulate negative pressure to promote the discharge of chest drainage liquid.The existing thoracic cavity closed drainage device used clinically is generally only made up of drainage bottle and drainage tube, negative pressure adjustment can only rely on artificial hands to smooth out with the fingers pipe and complete: first Pulvis Talci is spread upon drainage tube surface, then the right hand blocks drainage tube upper end, left hand blocks drainage tube glide downwards from top to bottom, to drainage tube hypomere, the right hand unclamps, thus strengthen drainage tube negative pressure, the cellulose draining frailish blood clot or solidify; Or the external Electric negative pressure actuator of closed thoracic drainage bottle, but Lasting vacuum aspiration may make damaged blood vessels healing time extend, thus drainage flow may be caused to increase, and Electric negative pressure suction pump cost is higher, increases patient medical expense.
This pipe of manually smoothing out with the fingers regulates negative pressure mode easily to rub pain finger, and wastes time and energy, and it is not good to smooth out with the fingers pipe effect by hand yet.
Summary of the invention
Existing thoracic cavity closed drainage device can only rely on manually smoothes out with the fingers pipe adjustment negative pressure, pain of easily rubbing finger, and wastes time and energy, poor effect.The purpose of this utility model is, for above-mentioned the deficiencies in the prior art, provides a kind of thoracic cavity closed drainage device control valve and this thoracic cavity closed drainage device.
For solving the problems of the technologies described above, the technical scheme that this utility model adopts is:
A kind of thoracic cavity closed drainage device control valve, described control valve comprises guide frame, the first roller and the second roller; Described guide frame both sides are oppositely arranged the track of inclination, and the axle core two ends of described first roller are placed in the track of guide frame both sides respectively; The axle core two ends of described second roller are embedded in two sidewalls of guide frame epimere respectively; The drainage tube of thoracic cavity closed drainage device is from top to bottom through described control valve, when the axle core two ends of the first roller are positioned at the top of track, drainage tube clamps by the first roller and the second roller, when the first roller is positioned at the least significant end of track, first pair of rollers drainage tube does not form compressing, drainage tube Full-open.
By this structure, when needs regulate negative pressure, first the first roller is rolled into the top of track, then the drainage tube above a hands secured adjusted valve, another hands is by control valve toward drop-down, and the direction namely toward drainage bottle is drawn, thus control valve can get rid of the drainage-fluid in section of passing by, in the drain pipeline section of passing by, form negative pressure, the negative pressure in drainage tube can promote the outflow of chest drainage liquid.Negative pressure Principles of Regulation of the present utility model with manually smooth out with the fingers pipe and regulate identical, but regulate during negative pressure and by the direct extrusion friction drainage tube of staff, need not avoid damaging staff, improve efficiency simultaneously.
In addition, the flow speed control valve used when this structure of described control valve and transfusion is similar, the openings of sizes that therefore can also be used to regulate half folder to close as required to regulate drain size, or be adjusted to entirely press from both sides close state after change drainage bottle.
As a kind of optimal way, described track is skewed slot.
Based on same inventive concept, this utility model additionally provides a kind of thoracic cavity closed drainage device, comprises drainage tube, and described drainage tube is from top to bottom through described control valve.
As a kind of optimal way, one end of described drainage tube is placed in chest, and the other end is placed in the bottom of drainage bottle.
Compared with prior art, this utility model structure is simple, and can not damage staff, use easy to operate, with low cost, efficiency is higher.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model one embodiment.
Wherein, 1 is control valve, and 11 is guide frame, and 12 is the first roller, and 13 is the second roller, and 14 is track, and 2 is drainage tube, and 3 is drainage bottle.
Detailed description of the invention
As shown in Figure 1, an embodiment thoracic cavity closed drainage device control valve 1 of the present utility model comprises guide frame 11, first roller 12 and the second roller 13; Described guide frame 11 both sides are oppositely arranged the track 14 of inclination, and the axle core two ends of described first roller 12 are placed in the track 14 of guide frame 11 both sides respectively; The axle core two ends of described second roller 13 are embedded in two sidewalls of guide frame 11 epimere respectively; The drainage tube 2 of thoracic cavity closed drainage device is from top to bottom through described control valve 1, when the axle core two ends of the first roller 12 are positioned at the top of track 14, drainage tube 2 clamps by the first roller 12 and the second roller 13, when the first roller 12 is positioned at the least significant end of track 14, first 12 pairs, roller drainage tube 2 does not form compressing, drainage tube 2 Full-open.
Described track 14 is skewed slot.
A kind of thoracic cavity closed drainage device, comprises drainage tube 2, and described drainage tube 2 is from top to bottom through described control valve 1.
One end of described drainage tube 2 is placed in chest, and the other end is placed in the bottom of drainage bottle 3.
When needs regulate negative pressure, first the first roller 12 is rolled into the top of track 14, then the drainage tube 2 above hands opisthotonos (or a pinching) control valve 1, another hands by control valve 1 toward drop-down, namely the direction toward drainage bottle 3 is drawn, thus make to form negative pressure in the drainage tube 2 between turn-over point to control valve 1, finally unclamp invagination, the negative pressure in drainage tube 2 can promote the outflow of chest drainage liquid.
In addition, the openings of sizes that described control valve 1 can also be used to regulate half folder to close as required to regulate drain size, or is adjusted to after full folder closes state and is changed drainage bottle 3.
If operate miss, control valve 1 pulls from one end end close to drainage bottle 3 toward chest end by operator by mistake, first roller 12 can roll to control valve 2 bottom under the effect of frictional force, thus cannot extrude drainage tube 2, avoids drainage-fluid to blow back into chest.
