Abstract

The utility model relates to a pressurizing syringe, which is composed of a needle head, a needle pipe and a pressurizing device of a needle bolt strand, wherein, the pressurizing device is composed of a screw plate, a screw rod, a slide bar, a slide plug, a lantern ring and a handle. Because a pressurizing device is sheathed on the basis of the existing syringe, the screw rod is propelled by rotating the handle, and a needle bolt of a normal syringe is pushed by a bolt to oppress physic liquor to enter the human body, use is labor-saving, quick, safe and reliable. The utility model has the advantages of simple structure, convenient operation, easy manufacture and low cost and is a quite ideal pressurizing syringe.

Description

Pressure injector

Technical field:

This utility model belongs to medical instruments field, particularly be the frequent pressure injector that uses of injection in the clinical treatment.

Background technology:

Syringe is the most a kind of apparatus of normal application in the clinical treatment work, uses syringe with the medicinal liquid of using, and different parts is injected in the various medicinal liquid processes in body, all is the pulling pintle, extracts medicinal liquid, uses the hand propelled pintle then, injecting liquid drug to the target position.In the bigger injection site of some resistances with when needing fast injection to require to reach treatment, and during the injection thick liquid, it is bigger often to require great effort with the hand propelled pintle, and does not reach specification requirement, and for example, the injection hypertonic glucose is annotated difficult with hand push.Some people adds the rubber band pulling and has an injection between needle tubing and pintle, alleviate people's thrust, and the injection speed shakiness is also not too safe like this, needs a kind of pressure injector of exploitation badly.

Summary of the invention:

The purpose of this utility model provides a kind of energy fast injection, thrust is bigger, energy safety, the laborsaving pressure injector of in time finishing the injection requirement.

The purpose of this utility model is achieved in that concrete technical scheme is described as follows;

A kind of pressure injector is made up of syringe needle, needle tubing, pintle, and its construction features installs pressue device additional in the needle tubing outside to be formed; The structure of pressue device is:

1. pressue device is made up of spiral shell plate, screw rod, slide bar, sliding plug, the collar; The spiral shell plate is a circular slab; Slide bar is made up of upper slide bar and drop shot;

2. two parallel upper and lower slide bar left ends, respectively with spiral shell plate border on upper and lower two corresponding point become vertical direction fixedly connected; Upper and lower slide bar right-hand member inwall becomes the vertical direction axle to be connected with upper and lower two corresponding point in outer, collar border respectively;

3. the upper and lower end walls of sliding plug is slidingly connected respectively and between the upper and lower slide bar inwall.

The advantage of this utility model pressure injector clearly, since be on the basis of existing syringe suit a pressue device, with rotary handle screw rod is advanced, the pintle compressing medicinal liquid that the reuse bolt promotes syringe commonly used enters human body, and is promptly laborsaving quick again, promptly safety is reliable again, and the structure letter, easy to operate, make easily, cost is low, is a kind of more satisfactory pressure injector.

Description of drawings:

Accompanying drawing 1 is existing syringe generalized section

Accompanying drawing 2 is existing syringe pressue device generalized section

Can find out by accompanying drawing 1, the syringe of general usefulness is made up of syringe needle 1, needle tubing 2, pintle 3, be that by human hand push pintle 3 medicinal liquid in the syringe 2 to be expelled to the people by syringe needle 1 intravital in the use, run into the medicinal liquid thickness or when advancing fast, it is big and more haste, less speed to only depend on hand-power to promote really effort.

Can find out that by accompanying drawing 2 the syringe pressue device is made up of spiral shell plate 8, screw rod 7, upper slide bar 5, drop shot 5-1, sliding plug 6, the collar 4; Spiral shell plate 8 is one certain thickness circular slab; Slide bar is made up of upper slide bar 5 and drop shot 5-1; Screw rod 7 is one externally threaded bolt, and spiral shell plate 8 has centre bore, and centre bore has female thread, and the interlock that is complementary of the female thread of the external screw thread of screw rod 7 and spiral shell plate 8 centre bores; Two parallel upper and lower slide bars 5,5-1 left end, respectively with spiral shell plate 8 borders on upper and lower two corresponding point become vertical direction fixedly connected; Upper and lower slide bar right-hand member inwall becomes the vertical direction axle to be connected with upper and lower two corresponding point in outer, the collar 4 border respectively, can be linked in together with the concave, convex mode, also can link together with the mode of axle and axle sleeve.Require distance between slide bar 5, the 5-1 should be slightly larger than the diameter of needle tubing 2 left end wings in the making, the diameter of the collar 4 is slightly less than the diameter of needle tubing 2 left end wings, purpose is that syringe can be packed among slide bar 5, the 5-1, and the collar 4 can be lived pintle 3 hind wings by shelves, makes needle tubing 2 moving to the right.At screw rod 7 left end fixed handles 11, more can laborsaving, propelling to the right fast.

The upper/lower terminal wall of sliding plug 6 is slidingly connected respectively and between the upper and lower slide bar 5,5-1 inwall, can be found out by accompanying drawing 2, when turning clockwise screw rod 7, changes screw rod 7 front ends and can promote sliding plug 6 and slide to the right.

For the ease of using and improving stability, on the left and right sidewall of sliding plug 6, establish groove 9,10 respectively; The front end groove 10 that groove 9 can block bolt 7 can block the left end of pintle 3.Establish handle 11 at screw rod 7 left ends, rotary screw 7 more easily and quickly.

The specific embodiment:

During this utility model pressure injector is made, there is not special processing request; Syringe utilizes existing product to get final product, and only producing the syringe pressue device that is complementary can supporting forming.Because existing syringe has several specifications of different capabilities, do not wait the multiple syringe of specification as 5ml-50ml-100ml commonly used, the syringe pressue device of several specifications that form a complete production network out gets final product.

Use: with usual manner medicinal liquid is sucked in the needle tubing 2 earlier, again the collar 4 is revolved and turn 90 degrees, the syringe of having taken out medicinal liquid is horizontally through the collar 4 by syringe needle 1 end, be stuck on the collar 4 until needle tubing 2 rear end wings, the collar 4 is turn 90 degrees together with syringe is counter, pintle 3 is entered, drop shot 5, between the 5-1 inwall, and needle tubing 2 rear end wings are stuck in the left side of the collar 4, at this moment twist handle 11 again, screw rod 7 up times are rotated, its right-hand member snaps in the sliding plug 6 left wall grooves 9, promoting sliding plug 6 right sides advances, the pintle left end is snapped in the sliding plug 6 right wall grooves 10, promote the pintle right side and advance, block under the motionless condition of needle tubing 2 that at the collar 4 medicinal liquid is pushed in the human body.

Do not have specific (special) requirements in the production of the present utility model, the colleague technical staff all can implement.
