Abstract
The utility model relates to a medical device, in particular to a negative pressure drainage device. The negative pressure drainage device comprises a drainage ball and a drainage tube connected to the drainage ball. The negative pressure drainage device is characterized in that a filter piece is arranged in the drainage tube and provided with a spike part. The negative pressure drainage device is simple in structure and convenient to use, drained objects can quickly enter the drainage ball, the drainage tube is not blocked easily, and the labor amount is reduced for workers while pain of patients is reduced.
Description
Technical field
This utility model relates to technical field of medical instruments, relates 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, the blood etc. that in body cavity, gather 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 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.
Utility model content
The purpose of this utility model is for the deficiencies in the prior art part, provides a kind of simple in structure, easy and simple to handle, prevents the depression drainage device of blocked drainage tube, makes drain thorough in time.
In order to solve the problems of the technologies described above, the technical solution of the utility model 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 utility model, 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, exudate larger 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, be provided with the joint of horn shape apart from 2CM place, described drainage tube one end, 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 under normal conditions, prevents that 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 along tapered tip, 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.
In the time that exudate is more, open liquid outlet and topple over after exudate, then close liquid outlet, can reuse drainage device.

Detailed description of the invention
The following stated is only preferred embodiment of the present utility model, not scope of the present utility model 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.Apart from the horn shape joint 5 and drainage ball 1 one end socket at drainage tube 2 2CM places, one end.Drainage tube 2 one end arrange check valve 6, and described check valve 6 is flat cone, have a gap along tapered tip.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 multiple 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, push drainage ball 1 by medical personnel with hands, 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 exudate larger 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.In the time that 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 to explanation of the present utility model, make those of ordinary skill in the art's can completely implement this programme, but be not to restriction of the present utility model, those skilled in the art are reading after this description and can make to the present embodiment the amendment that there is no creative contribution as required, and these are all not creative amendments.But as long as within the scope of claim of the present utility model, be all subject to the protection of Patent Law.
