Abstract

The utility model relates to a drug delivery device, the technical proposal of which is as follows: a main body structure is composed of a pump box, a coupling head and an infusion soft tube, the coupling head is composed of a core tube and a thread pressing cover which are integrated, the two parts can be made into the separated type, when in use, the two parts can be assembled together to combine the coupling head; the infusion tube is a medical rubber tube. The innovation of the utility model is that the head part of the core tube of the coupling head adopts a broken melon wedge structure in all the components; a circle center of a round head or a flat round head of the head part of the core tube is opened with grooves as wedges, the number of the grooves as wedges is 2 to 10, when in use, the coupling head thread pressing cover is screwed tightly after a round tube of the broken melon wedge type core tube enclosing the infusion soft tube, and the broken melon wedge of the head part of the core tube expands the infusion tube tightly by relying on the expansive force. The utility model has the benefits that: the utility model is more safe and reliable than the normal drug pump boxes, the infusion tube is unlikely to shed; furthermore, the utility model can be used for increasing the pressure or decreasing the pressure of the blood blockers and have good control function of the blood supply of the target organs.

Description

Doser

Doser belongs to a kind of and in the subcutaneous injection mode medium is introduced intravital medical apparatus and instruments.

At present, relevant technology report and production marketing are arranged; Invalid patent 94221146, the description of " Endermic implantating device for administration of drugs " is the most approaching prior art document of the present utility model, import Teat pipette pump box then is immediate existing product, and also having home-made old-fashioned Teat pipette pump box in addition also is reference background technology of the present utility model.Because this utility model is to have adopted " melon processing wedge " expansion type extruding draw bail in that the coupling head of key is technical, is a kind of innovation to this class technology.

The purpose of this utility model is, a kind of doser that uses " expansion type extruding draw bail " parts is provided, and it is more safe and reliable than common Teat pipette pump box, and can be used for the pressurization or the decompression of device of blocking out blood flow.

Its technical scheme is as follows:

The agent structure of doser is made of pump box, coupling head, infusion tube assembling, and its pump box is made up of box body 1, capping 2, injection flexible glue lid 3 and needle tubing 4; Coupling head screws gland 6 by incorporate coupling head core pipe 5 and screw thread and constitutes, and it is split type that two parts also can be made, and is fitted together the composition coupling head in use; Tube for transfusion 7 is medical sebific ducts, and one is contained in the core pipe and the doser connection, and the other end is connected on dispenser target organ, lesions position or the block device.In all members of the present utility model, innovation is that the core tube head of coupling head has adopted " melon processing wedge " structure: with the round end of core tube head or the circle centre position of flat round end, with the method that waits the branch central angle circle at place is left some grooves, its groove stricture of vagina such as melon are so be named " melon processing wedge "; The fluting number is 360 °/n, i.e. the five equilibrium round end; The number of slotting into wedge is 2-100, and also available not bisecting method is slotted into wedge.After the pipe of " melon processing wedge " core barrel encases infusion tube during use, screw the coupling head union (screwed)bonnet (UB, " melon processing wedge " of core tube head incited somebody to action dependence expansive force swelling tube for transfusion tightly.

Its benefit is: this utility model is more safe and reliable than common Teat pipette pump box, the tube for transfusion difficult drop-off; And can be used for the pressurization or the decompression of device of blocking out blood flow, the blood supply of target organ is had good control action.
