Description

A kind of external sucked type negative pressure drainage device

Technical field

This utility model relates to a kind of medical apparatus and instruments, is specifically related to a kind of external sucked type negative pressure drainage device.

Background technology

When patient is subject to various acute injury, during the situations such as the ulcer that skin, soft tissue injury and a variety of causes cause, wound surface generally there will be secretions, faster in order to make the wound healing of patient obtain, and generally needs secretions to remove.Wound surface closed negative pressure treatment technology is the new Wound treatment technology that development in recent years is got up.Result of study surface, closed negative pressure can promote acute and chronic wound healing, and has been widely used in the treatment of a series of intractable wound, can accelerate the healing infecting the closed of lacuna and infective wound surface.Remove the processing mode of secretions to be generally and to utilize the negative pressure device with drainage tube, drainage material and biological permeable membrane to close wound surface and the external world are separated, drainage tube is connected with negative pressure source.But when specifically using, existing negative pressure drainage device needs negative pressure source work to remain on normal condition always, once negative pressure source work is abnormal, the negative pressure distress resolves produced or deficiency, secretions or the fragment of tissue of vacuum suction wound out are then likely back to wound surface by negative pressure drainage device, cause secondary pollution to the wound surface of patient.

Utility model content

This utility model aims to provide a kind of external sucked type negative pressure drainage device, and its structure is simple, easy to use and reliable.Effectively can prevent the secretions of wound or fragment of tissue from being refluxed by external sucked type negative pressure drainage device, be conducive to the clean of wound surface and healing.

The technical solution of the utility model is a kind of external sucked type negative pressure drainage device, comprise disk body, the drainage channel of through disk body upper and lower surface, the drain that is connected with disk body upper surface be responsible for, drain supervisor end is provided with a lid, drain supervisor sidewall is connected with drain time pipe, drainage channel and drain are responsible for and are connected, the position of disk body lower surface skew drainage channel is provided with plush copper, and plush copper cross-sectional area accounts for the 10%-60% of disk body lower surface area.

Further, built-in Medical check valve in described drain time pipe, the Medical check valve in drain time pipe is unidirectional outflow.

Further, described disk body upper surface is coated with transparent applicator, transparent applicator have for drain supervisor through hole.Transparent applicator covers disk body remainder completely.

Further, the material of described disk body, drain supervisor, drain time pipe and plush copper is any one in medical grade silicon rubber, medical polyvinyl, medical polyurethane, medical pla-pcl, medical latex, medical polyethylene or polypropylene for medical article.

This utility model is being responsible for built-in Medical check valve in joining drain time pipe with drain, when the negative pressure source work that connects with external sucked type negative pressure drainage device can be prevented abnormal, be attracted to the secretions of the wound in external sucked type negative pressure drainage device or fragment of tissue because of the negative-pressure sucking that negative pressure source produces by negative pressure source disappear or reduce and be back to patient wound, effectively can ensure the clean conditions of patient's wound surface, make it recover early.

In figure: 1. disk body, 2. drainage channel, 3. drain supervisor, 4. drain time pipe, 5. Medical check valve, 6. lid, 7 transparent applicators, 8. plush copper.

Detailed description of the invention

In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with accompanying drawing, the present invention is further elaborated.

As depicted in figs. 1 and 2, this utility model provides a kind of negative-pressure drainage sucker device, it comprises disk body 1, drainage channel 2, drain supervisor 3, drain time pipe 4, lid 6 and plush copper 8, described drainage channel 2 through disk body 1 upper and lower surface, described drain supervisor 3 is connected with disk body 1 upper surface, drainage channel 2 and drainage tube 3 connect, described drain is responsible for 3 sidewalls and is connected with drain time pipe 4, described drain is responsible on 3 ends and is provided with a lid 6, plush copper 8 is provided with in the position of disk body 1 lower surface skew drainage channel 2, the cross-sectional area of plush copper 8 accounts for the 10%-60% of disk body 1 lower surface area.

Further, built-in Medical check valve 5 in described drain time pipe 4, the Medical check valve 5 in drain time pipe 4 is unidirectional outflow.

Further, described disk body 1 upper surface is coated with transparent applicator 7, and transparent applicator 7 has the hole passed for drain supervisor 3.Transparent applicator 7 covers disk body 1 remainder completely.

Further, the material of described disk body 1, drain supervisor 3, drain time pipe 4 and plush copper 7 is any one in medical grade silicon rubber, medical polyvinyl, medical polyurethane, medical pla-pcl, medical latex, medical polyethylene or polypropylene for medical article.

This utility model in use, first clear up the wound of patient, wound covers and fixes porous foam, porous foam is fixed negative-pressure drainage sucker device, plush copper 8 on sucker is contacted with porous foam, and close sucker and porous foam formation confined space with transparent applicator 7, space between plush copper 8 is formed can the passage of drain, the secretions of wound or fragment of tissue enter by the space between plush copper 8 and draw in negative-pressure drainage sucker device, by drain supervisor 3 be responsible for the secondary pipe 4 of 3 drains connected with drain and be connected to negative pressure device, whole wound surface is made to be in negative-pressure sealed drainage state, start negative pressure source, negative-pressure drainage sucker device starts to attract the secretions at wound place or fragment of tissue to enter negative-pressure drainage sucker device, flow out from drain time pipe 4, as abnormal in negative pressure source work, the negative pressure distress resolves produced or reduction, the secretions or the fragment of tissue that are attracted out the wound place entering drain time pipe 4 are stopped by Medical check valve 5, the secondary pollution that wound place causes patient's wound surface can not be back to, ensure the clean conditions of patient's wound surface, it is made to recover early.

Certainly; this utility model also can have other various embodiments; when not deviating from this utility model spirit and essence thereof; those of ordinary skill in the art can make various corresponding change and distortion according to this utility model, but these change accordingly and are out of shape the protection domain that all should belong to the claim appended by this utility model.
