Abstract
The invention relates to a medical instrument, and particularly relates to a negative pressure drainage apparatus. The negative pressure drainage apparatus disclosed by the invention comprises a drainage ball and a drainage pipe connected to the drainage ball. The negative pressure drainage apparatus is characterized in that a filter plate is arranged inside the drainage pipe; and a spine section is arranged on the filter plate. The negative pressure drainage apparatus is simple in structure and convenient to use, drain can quickly enter the drainage ball, the drainage pipe is hardly blocked, and the workload of a medical worker is reduced when pain of a patient is relieved.
Description
Technical field
The present invention relates to technical field of medical instruments, relate in particular a kind of depression drainage device.
Background technology
Patient needs drain at surgery post-operative wound exudate, the object of drain be by operation between tissue or the pus gathering in body cavity, blood etc. be directed to externally, prevent postoperative infection and affect wound healing.Existing drainage device in use easily causes blocked drainage tube, thereby affects drainage effect or the drainage device that needs repeatedly to peg graft in patient body increases patient's misery of performing the operation.
Granted publication number is CN86201263U, and the day for announcing is that the Chinese utility model patent on March 18th, 1987 discloses a kind of vacuum liquid extractor for operation, and in this patent document, disclosed this vacuum liquid extractor for operation comprises drainage device body, drainage tube and check valve.Its object aim to provide a kind of processing technology convenient, assemble simple, non-leakage, cheap vacuum liquid extractor for operation, do not solve in drain process exudate in patient body and stop up check valve, thereby cause the incomplete problem of drain.
Summary of the invention
The object of the invention is for the deficiencies in the prior art part, provide a kind of simple in structure, easy and simple to handle, prevent the depression drainage device of blocked drainage tube, make drain thorough in time.
In order to solve the problems of the technologies described above, technical scheme of the present invention is as follows: a kind of depression drainage device, and comprise drainage ball and be connected to the drainage tube on drainage ball, in described drainage tube, be provided with filter, described filter is provided with sharp portion.
Depression drainage device of the present invention, by pushing drainage ball with hands, in drainage device, produce negative pressure, thereby the hydrops in patient body and operation exudate are sucked in drainage device, by the filter with spine arranging in drainage tube, the larger exudate of area is stopped or punctured simultaneously, after exudate that these areas are larger is inhaled into, check valve is stopped up preventing, thereby affect drainage effect.
As preferably, on described filter, be provided with successively long spine and short spine.
On filter, set gradually long spine and short spine, can more effectively stop or puncture the exudate that area is larger.
As preferably, apart from 2CM place, described drainage tube one end, be provided with the joint of horn shape, described joint and the socket of drainage ball one end.
The socket of the joint of drainage tube one end horn shape and drainage ball one end, not only easy and simple to handle, stable connection but also good airproof performance there will not be the phenomenon of seepage.
As preferably, described drainage tube one end is provided with check valve.
Drainage tube one end arranges check valve, one-way valve opens opening under negative pressure state, and the exudate inflow drainage ball of taking advantage of a situation, closed check valve opening, prevents that exudate from refluxing under normal conditions.
As preferably, described check valve is flat cone, along tapered tip, has a gap.
Check valve is flat cone, along tapered tip, has a gap, prevents the better effects if that exudate refluxes.
As preferably, described check valve, drainage tube, joint is one-body molded makes.
Check valve, drainage tube, joint is one-body molded makes, and process velocity is fast, quality good, easy to operate, is easy to carry.
As preferably, described drainage ball bottom is provided with liquid outlet.
When exudate is more, open liquid outlet and topple over after exudate, then close liquid outlet, can reuse drainage device.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is described further:
Fig. 1 is the schematic perspective view of one embodiment of the invention;
Fig. 2 is filter schematic diagram.
In figure:
1-drainage ball;
2-drainage tube;
3-filter;
4-sharp portion;
5-joint;
6-check valve;
7-liquid outlet.
The specific embodiment
The following stated is only preferred embodiment of the present invention, not scope of the present invention is limited.
Embodiment, is shown in accompanying drawing 1, and a kind of depression drainage device comprises drainage ball 1 and is connected to the drainage tube 2 on drainage ball 1, and in drainage tube 2, be provided with filter 3, filter 3 is provided with sharp portion 4.Horn shape joint 5 and drainage ball 1 one end socket apart from drainage tube 2 2CM places, one end.Drainage tube 2 one end arrange check valve 6, and described check valve 6 is flat cone, along tapered tip, have a gap.Drainage ball 1 bottom is provided with liquid outlet 7.Described check valve 6, drainage tube 2, joint 5 is one-body molded makes.
As shown in Figure 2, in order to increase blockage resisting effect, the length that filter 3 is provided with a plurality of sharp portions 4 and sharp portion 4 differs, and can effectively stop or puncture the exudate that area is larger.
In operation, drainage device one end is connected in patient body, by medical personnel, with hands, push drainage ball 1, in drainage device, produce negative pressure, hydrops in patient body and operation exudate are sucked in drainage ball 1 through drainage tube 2, the filter 3 with spine of drainage tube 2 interior settings stops the larger exudate of area or puncture, and effectively prevents that the exudate that area is larger from stopping up drainage tube 2.The check valve 6 stretching in drainage ball 1 is opened opening under negative pressure state, and exudate is taken advantage of a situation and flowed into drainage ball 1, closes under normal conditions opening, prevents that exudate from refluxing.When drainage ball 1 is filled exudate, open drainage ball 1 bottom liquid outlet 7, after exudate is toppled over, then close liquid outlet 7 and re-start drain.
More than explanation is only explanation of the invention, make those of ordinary skills' can completely implement this programme, but be not limitation of the present invention, those skilled in the art can make to the present embodiment the modification that there is no creative contribution as required after reading this description, and these are all not creative modifications.But as long as within the scope of claim of the present invention, be all subject to the protection of Patent Law.
