Abstract
The present invention relates to a kind of dedicated disposable negative-pressure sealed shield traumatic material of finger and its instruments, including VSD auxiliary material sponge, biological semi-permeable film, drainage tube, link, connector, pipette, imbibition pipe clamp, connecting hole one, attachment base one, imbibition bottle with sucker, attachment base two, breather cheek valve, unidirectional air outlet valve, hand pinches ball, antibiotic layer, adhered layer, the connection structure of the shield traumatic material from inside to outside is successively are as follows: adhered layer → antibiotic layer → VSD auxiliary material sponge → biological semi-permeable film, it is connect inside VSD auxiliary material sponge with drainage tube, drainage tube is connect by connector with pipette, has imbibition pipe clamp in pipette, imbibition bottle with sucker top, which is kept right, attachment base one, there is connecting hole one on attachment base one, one upper end of connecting hole is connect with pipette, imbibition bottle with sucker top, which is kept right, attachment base two, attachment base two is pinched ball with hand by breather cheek valve and is connect , hand, which pinches ball bottom end and keeps left, unidirectional air outlet valve.The present invention can reduce doctor's workload, shorten the operating time, and can provide corresponding negative pressure.
Description
Technical field
The present invention relates to the field of medical instrument technology, specifically, being a kind of dedicated disposable negative-pressure sealed shield wound of finger
Material and its instrument.
Background technique
Negative-pressure sealed drainage technology (VacuumSealingDrainage, VSD) is a kind of various complicated surface of a wound of processing and use
In the completely new approach of deep drainage, which has become the standard care mode of processing orthopaedics and a variety of surface of a wound of surgery.Negative pressure envelope
It closes drainage to refer to VSD auxiliary material sponge, to cover or fill the surface of a wound of skin, soft tissue defects, then with biological semi-permeable film to it
It is closed, becomes a confined space, drainage tube is finally connected negative pressure source, promote to create by controllable negative pressure
The completely new treatment method of one kind of face healing.The characteristics of technology, is that the high negative pressure environment that closing drainage is formed makes to be drained
Area is isolated from the outside world, and effectively prevent pollution and cross-infection；Meanwhile high negative pressure closing can be with the sepage of the continuous drainage surface of a wound, purulence
Liquid and necrotic tissue etc. make to be drained in area and reach " nil product is poly- ", and the surface of a wound can obtain clean environment quickly, effectively facilitate more
It closes.
The operation of negative-pressure sealed drainage be segmented into the following three steps:
1, VSD auxiliary material sponge is fitted in into the surface of a wound, is sufficiently covered, it is ensured that drainage is abundant；
2, the biological semi-permeable film for being used to seal is pasted and is wrapped in except sponge, so that drainage area is isolated from the outside world, determine close
After closing completely, negative pressure drainage device is accessed；
3, start to drain, the surface of a wound is made to form subnormal ambient.VSD auxiliary material sponge is essential used in this technology
, soft high resilience, tension stress is strong, and there is pole in the gap of the interior 0.2~1.0mm of diameter largely to communicate with each other that gathers
Good plasticity and water penetration and good biocompatibility.Negative pressure suction device by act on VSD auxiliary material sponge formed it is negative
Pressure ring border is conducive to that treatment purpose is better achieved.
In clinical hand injury, especially in fingertip injury, when using negative-pressure sealed drainage technology, need with VSD auxiliary material
The entire finger of sponge wrapping, however current product VSD auxiliary material sponge is usually monolith regular rectangular shape, when use, need to be repaired
It cuts to the suitable dimension that can wrap up finger.In addition, during plastotype, being needed because of the separation of auxiliary material sponge and biological semi-permeable film
It wants two people to assist, could cover sealing film while fixed sponge auxiliary material.Therefore, current negative-pressure sealed drainage technology
During integrated operation, inconvenient for use and labor intensive has further improvement space.
Depression drainage device connects the drainage tube with patient when in use, is used for the intracorporal liquid of patient (such as ponding)
It is drawn in flow diverter.Existing common depression drainage device is all the negative pressure pre-set in flow diverter, which is connected to
After drainage tube with patient, due to being negative pressure state in flow diverter, directly the intracorporal liquid of patient can be drawn in bottle.But
Have the following defects in actual use, preset negative pressure does not usually meet actual demand, negative pressure it is excessively high or it is too low all can be right
Patient impacts.
Chinese patent application: CN203874181U discloses a kind of portable hand closed negative pressure drainage device, comprising: negative
Press drainage component；Wound dressing；And surface of a wound closed film, wherein the negative pressure drainage component includes mobile negative-pressure source, until
A few drainage tube, and the pipe clamp of the control drainage tube on-off, the Wound dressing is corresponding with the shape of hand, has
The flexible absorbent layer directly contacted with the surface of a wound, and wrap up in the hard layer for being located at the flexible absorbent layer periphery, and with it is described
Drainage tube is connected and protrudes into the drainage tube interface of the flexible absorbent layer.
Chinese patent application: CN206414542U discloses a kind of hand VSD negative pressure drainage instrument, including hand shape dressing
Layer, the interior setting drainage tube of hand shape auxiliary material layer and flushing pipe, surface of a wound closed film, wherein equal in the setting of the dressing layer part of drainage tube
Even opening drains pipe end by connection structure and connects negative pressure suction device；The drainage tube is to open with flushing pipe finger tips
Mouth structure on the other end, rinses pipe end and plugging cap is arranged, drainage pipe end setting stopped pipe presss from both sides, and the hand shape dressing layer can be cut out
It cuts.In addition settable two layers opposite hand shape dressing layer is drawn two negative pressure using tee tube when using double-layer structure simultaneously
Flow tube is connect with negative pressure device.But above-mentioned two patent is not involved with the antibiotic property problem of VSD auxiliary material sponge, and uses
When, other medical staff is required to assist pressing VSD auxiliary material sponge, to be drained.In hand injury clinical practice,
