Abstract
The present invention relates to a kind of medical apparatus and instruments, particularly relate to a kind of depression drainage device.Depression drainage device of the present invention comprises drainage ball and is connected to the drainage tube on drainage ball, and it is characterized in that being provided with filter in described drainage tube, described filter is provided with sharp portion.Structure of the present invention is simple, easy to use, drain can be made to enter drainage ball rapidly, and drainage tube not easily blocks, and while alleviating patient's misery, reduces the amount of labour of medical worker.
Description
Technical field
The present invention relates to technical field of medical instruments, relate to a kind of depression drainage device in particular.
Background technology
Patient needs drain at surgical wounds exudate, the object of drain be by operation between tissue or the pus, blood etc. that gather in body cavity be directed to external, prevent postoperative infection and affect wound healing.Existing drainage device in use easily causes blocked drainage tube, thus affect drainage effect or need repeatedly in patient body grafting drainage device increase patient and to perform the operation misery.
Authorization Notice No. 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 disclosed in this patent document, 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, not solve in drainage process exudate blocking check valve in patient body, thus 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 structure simple, 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, be provided with filter in described drainage tube, described filter is provided with sharp portion.
Depression drainage device of the present invention, by extruding drainage ball with hands, negative pressure is produced in drainage device, thus the hydrops in patient body and operation exudate are sucked in drainage device, simultaneously by arrange in drainage tube with spine filter by exudate larger for area stop or puncture, after being inhaled into prevent the larger exudate of these areas, check valve is blocked, thus affect drainage effect.
As preferably, described filter is provided with successively long spine and short spine.
Filter sets gradually long spine and short spine, can more effective stop or puncture the larger exudate of area.
As preferably, be provided with the joint of horn shape apart from 2CM place, described drainage tube one end, described joint and drainage ball one end are socketed.
Joint and drainage ball one end of drainage tube one end horn shape are socketed, and 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 exudate is taken advantage of a situation inflow drainage ball, under normal conditions closed check valve opening, prevents exudate from refluxing.
As preferably, described check valve is flat cone, has a gap along tapered tip.
Check valve is flat cone, has a gap, prevent the better effects if that exudate refluxes along tapered tip.
As preferably, described check valve, drainage tube, joint are one-body molded to be made.
Check valve, drainage tube, joint are one-body molded to be made, and process velocity is fast, quality good, easy to operate, is easy to carry.
As preferably, bottom described drainage ball, be provided with liquid outlet.
When exudate is more, opens after liquid outlet topples over exudate, then close liquid outlet, can drainage device be reused.

Detailed description of the invention
The following stated is only preferred embodiment of the present invention, not limits scope of the present invention.
Embodiment, is shown in accompanying drawing 1, a kind of depression drainage device, and the drainage tube 2 comprising drainage ball 1 and be connected on drainage ball 1, be provided with filter 3 in drainage tube 2, filter 3 is provided with sharp portion 4.Horn shape joint 5 apart from 2CM place, drainage tube 2 one end is socketed with drainage ball 1 one end.Drainage tube 2 one end arranges check valve 6, and described check valve 6, in flat cone, has a gap along tapered tip.Liquid outlet 7 is provided with bottom drainage ball 1.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, filter 3 is provided with multiple sharp portion 4 and the length of sharp portion 4 differs, and can effectively stop or puncture the larger exudate of area.
In operation, drainage device one end is connected in patient body, drainage ball 1 is extruded with hands by medical personnel, negative pressure is produced in drainage device, hydrops in patient body and operation exudate are sucked in drainage ball 1 through drainage tube 2, exudate larger for area stops or punctures by the filter 3 with spine arranged in drainage tube 2, the exudate blocking drainage tube 2 effectively preventing area larger.The check valve 6 stretched in drainage ball 1 opens opening under negative pressure state, and exudate is taken advantage of a situation and flowed into drainage ball 1, closes opening under normal conditions, prevents exudate from refluxing.When drainage ball 1 is filled exudate, open liquid outlet 7 bottom drainage ball 1, after exudate is toppled over, then close liquid outlet 7 and re-start drain.
More than illustrate it is only explanation of the invention, those of ordinary skill in the art's can completely is made to implement this programme, but be not limitation of the present invention, those skilled in the art can make to the present embodiment the amendment not having creative contribution as required after reading this description, and these are all not creative amendments.As long as but be all subject to the protection of Patent Law in right of the present invention.
