Abstract
The utility model discloses syringes, including syringe and push rod, the push rod inlet of the syringe is installed by finger pressing section, the cross-sectional shape of the push rod is cross, it is characterized in that, the edge of the push rod longitudinally opens up multiple card slots, support rod is installed in the finger pressing section, one end of the support rod is connect with finger pressing section, and the other end of the support rod can be inserted into card slot；One end in the support rod insertion card slot is arranged elastic anti-slip set；Antiskid thread is arranged in the side wall of the card slot.Syringe in the utility model, by the way that support rod is arranged between push rod and syringe, and support rod is stuck in the card slot of push rod, make to keep negative pressure state in syringe for a long time, the situation that supporter easily slides, fixing intensity is low and supporter is easy to be lost can be effectively prevent to occur.
Description
Technical field
The utility model relates to medicine technology field more particularly to syringes.
Background technique
Negative pressure wound therapy is to form subnormal ambient in wound using vacuum plant, to extract wound fester and infectious agent out
Matter, and attract health tissues liquid to maintain moist Curing circumstance, and promote peripheral blood microcirculation and reach and wound is accelerated to be cured
The effect of conjunction.Currently, medical staff mostly uses conventional syringe to manufacture subnormal ambient, make length in syringe since push rod need to be pulled out
Time keeps negative pressure, and existing mode of operation is: being stuck between the push rod of syringe and syringe using needle cap or other objects.On
Stating mode of operation, there are supporters easily to slide, the disadvantage that fixing intensity is low and supporter is easy to be lost.
Utility model content
For solve keep negative pressure in syringe for a long time in the prior art, existing supporter easily slides, fixing intensity it is low with
And the technical problem that supporter is easy to be lost, the technical solution of the utility model are as follows:
The push rod inlet of syringe in the utility model, including syringe and push rod, the syringe is installed by finger pressing section, institute
The cross-sectional shape for stating push rod is cross, and the edge of the push rod longitudinally opens up multiple card slots, the finger pressing section installation branch
One end of strut, the support rod is connect with finger pressing section, and the other end of the support rod can be inserted into card slot；The support rod is inserted
Enter one end in card slot and be arranged elastic anti-slip set, antiskid thread is arranged in the side wall of the card slot.
In a preferred embodiment, fixed block, the support rod and fixed block are installed by turning in the finger pressing section
Axis is hinged.
In a preferred embodiment, the card slot is equidistant arrangement.
In a preferred embodiment, the spacing of the card slot is 4mm, 6mm, 8mm or 10mm.
In a preferred embodiment, the material of the support rod is rigid plastics.
In a preferred embodiment, the shape of the support rod is L shape.
Syringe in the utility model, compared with prior art, it has the advantage that:
Syringe in the utility model by the way that support rod is arranged between push rod and syringe, and support rod is stuck in and is pushed away
In the card slot of bar, make to keep negative pressure state in syringe for a long time, can effectively prevent that supporter easily slides, fixing intensity is low and branch
Object situation easy to be lost is supportted to occur.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of syringe in the utility model.
Specific embodiment
Below in conjunction with the attached drawing of the utility model, the technical solution of the utility model is clearly and completely described.
Based on the embodiments of the present invention, obtained by those of ordinary skill in the art without making creative efforts
Every other embodiment, fall within the protection scope of the utility model.
As shown in Figure 1, the utility model provides syringe, finger pressing section 6, push rod 2 are installed in 2 inlet of push rod of syringe 1
Cross-sectional shape be cross, push rod 2 opens up multiple card slots 5, and support rod 3, one end of support rod 3 and finger are installed in finger pressing section 6
Splenium 6 connects, and the other end of support rod 3 can be inserted into card slot 5, and one end that support rod 3 is inserted into card slot 5 is arranged elastic anti-slip set
7, antiskid thread is arranged in the side wall of the card slot.Support rod 3 may be stuck between push rod 2 and syringe 1, when in syringe 1 be negative pressure shape
When state, push rod 2 can be effectively prevent movable into syringe 1.Support rod 3 connect with syringe and is stuck in card slot 5, and fixation can be improved
Intensity simultaneously avoids supporter from losing, and elastic anti-slip set 7 and antiskid thread can increase frictional resistance, prevents support rod 3 out of card slot 5
It slides.Also it can be horizontally arranged a stiff rod in a card slot 5 nearest apart from finger pressing section, stiff rod is made to be stuck in card slot 5 and finger pressure
Between portion, anti-throw-out lever 2 is movable into syringe 1.
Support rod 3 can be fixedly connected or be flexibly connected with finger pressing section 6, for convenient for operation, fixed block 4, branch are installed in finger pressing section
Strut 3 is hinged by shaft with fixed block 4, surrounds support rod 3 and rotates with the junction of fixed block 4.
For the stretching of push rod 2 is accurately positioned convenient for medical staff, card slot 5 is equidistantly to arrange, spacing 4mm,
6mm, 8mm or 10mm.
To further increase support strength, the material of support rod 3 is rigid plastics, acetal resin can be selected or poly- to benzene
Diformazan acids plastics；The shape of support rod 3 is L shape, is made in bending part insertion card slot 5.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in variation
Or replacement, it should be covered within the scope of the utility model.Therefore, the protection scope of the utility model should be with the power
Subject to the protection scope that benefit requires.
