Description
Technical field
The present invention relates to the field of medical instrument technology, specially a kind of syringe drainage fixing device.
Background technology
Syringe negative-pressure drainage is the principle using vacuum suction, and subatmospheric pressure is generated at the surface of a wound, is sucked out
The subcutaneous liquid of the surface of a wound.In the postoperative application disposable syringe negative pressure drainage of plastic surgery, effective drainage can not only be kept, and
Convenient for observation drainage-fluid property and accurate recording drainage flow, flap necrosis, the generation of the complication such as infection are reduced.
Orthopaedic patients operation after would generally indwelling disposable syringe continuous negative pressure drainage, clinically usually in syringe
Bottom and piston rod between setting syringe needle support piston rod, with fixed piston, to ensure the negative pressure in syringe.But
In prolonged fixation procedure, due to the activity of patient itself or the external world, syringe needle is easy to fall off, so as to cause work
Plug movement can not make to keep negative pressure in syringe.And due to syringe needle can not adjustment length, such syringe cannot be satisfied different journeys
Spend the requirement of vacuum suction.In addition, clinically mostly syringe is fixed on patient using papery Breathable adhesive tape, still, by
It is pasted in prolonged, is turned on patient bed in addition or out-of-bed activity, adhesive plaster do not glue, have the danger of de- pipe.Furthermore negative pressure is drawn
During stream, just needs syringe removing the hydrops being discharged in it at regular intervals, need to reuse adhesive plaster after removing
Syringe is fixed on patient, it is not only troublesome in poeration, also reduce the working efficiency of medical staff.
Invention content
The invention is intended to provide a kind of syringe drainage fixing device, to solve in the prior art since syringe needle is easy to take off
Falling causes piston rod to fix unsteady problem.
In order to achieve the above object, the present invention provides the following technical solutions：
A kind of syringe drainage fixing device, including supporting rack, supporting rack one end are provided with through-hole, are arranged in supporting rack
There is placement plate, placing groove is provided in placement plate, several card slots are both provided on the side wall of placing groove both sides, are laterally set above card slot
It is equipped with sliding slot, card slot is connected to sliding slot, is slided in placing groove and is provided with slide plate, slide plate, which is provided at both ends with, to be caught in card slot
Pawl is connected with spring between side of the slide plate far from through-hole and the placement plate other end, the slide plate other side is provided with mounting hole, peace
Dress is provided with air bag in hole, tracheae is symmetrically arranged on the side wall of mounting hole, tracheae one end is connected to air bag, in the tracheae other end
Sliding is provided with slide bar, and slide bar is connected with clamping jaw, and clamping jaw is located in mounting hole.
The principle of this programme is：
Placement plate is used to support placement plate for placing syringe, supporting rack, and through-hole is used to place the conduit of drainage, peace
Clamping jaw in dress hole is used to clamp the piston rod of syringe so that piston rod is connect with slide plate, can be pulled by sliding skateboard
Piston rod realizes negative pressure, and the pawl on slide plate is for being clamped in card slot to realize the fixation of piston rod.When practice, it will note
Emitter is placed in the placing groove in placement plate, and the piston rod of syringe is inserted into mounting hole, can be incited somebody to action when piston rod is inserted into
In gas extrusion to tracheae in air bag, the endotracheal sliding bar of gas push, slide bar pushes clamping jaw that it is made to clamp syringe
Piston rod, be achieved in the connection of piston rod and slide plate.Slide plate slides are driven after the completion of fixed so that the pawl card on slide plate
Enter the fixation placed and piston rod can be completed in the card slot in groove sidewall, connects syringe at this time and negative pressure can be completed with conduit.
When release plunger bar, it need to only push up in the detent slide to sliding slot that slide plate makes thereon.
This programme has the beneficial effect that：
1, by the way that the piston rod of syringe to be connect with slide plate, pawl is set on slide plate, and is set on placing groove sidewall
Card slot is set, the fixation of piston rod can be completed in card slot by the way that pawl to be caught in, it is middle compared with prior art to be pushed against by syringe needle
Fixed piston rod between syringe and piston rod, it is fixed more firm using this programme fixed piston rod, it can ensure to inject
Continuous negative pressure in device.
2, mounting hole on slide plate is set, and air bag is set in mounting hole, the piston rod of syringe is inserted into mounting hole
When can be thus real by the gas extrusion to tracheae in air bag, using gas push clamping jaw to clamp the piston rod of syringe
The connection of existing piston rod and slide plate, it is easy to operate, and stable connection.
3, it is connected to card slot by the way that sliding slot is arranged above card slot, pushing up slide plate keeps pawl thereon sliding from card slot
Enter i.e. releasable slide plate in sliding slot, is convenient for the adjusting of different negative pressure drainage situation lower piston rods.
Further, it is hinged on supporting rack in the middle part of placement plate, is all connected between placement plate both ends bottom and support frame bottom
There is telescopic rod, blow-off pipe is provided with below through-hole.Placement plate is pressed down on close to one end of through-hole so that placement plate rotates, i.e.,
It may make syringe to be detached from conduit, then syringe be connected to the discharge that hydrops in syringe can be realized with blow-off pipe.It is whole
A process is easy to operate without removing syringe, improves the working efficiency of medical staff.
Further, sliding is provided with the pressing plate that can be caught in through-hole above through-hole, and pressing plate both ends are with placement plate close to logical
The one end in hole is connected with drawstring.Placement plate can pull pressing plate when rotating by drawstring so that and pressing plate compresses the conduit in through-hole,
Prevent the hydrops that conduit is detached from syringe in rear tube from overflowing.
Further, anti-slop serrations are provided on the inside of clamping jaw.Anti-slop serrations can increase the friction between clamping jaw and piston rod so that
Piston rod is fixed more firm.
Further, be connected with elastic band on the side wall of supporting rack side, the elastic band other end and supporting rack other side side wall it
Between be connected with connector.Elastic band is connected on supporting rack by the way that elastic band to be wrapped in patient, and using connector,
Whole device can be so fixed on patient, be convenient for patient's out-of-bed activity during negative pressure drainage.
Further, it places in groove sidewall and is provided with elastic component.Syringe can squeeze placing groove when being placed into placing groove
Elastic component on side wall, elastic component can utilize the elastic restoring force of itself to push against syringe so that syringe can be more steady
Solid be placed in placing groove.
