Description

External wound drug delivery device

Technical Field

The utility model relates to a medical instrument, an external wound device of dosing specifically says so. It is mainly suitable for the administration of gel, and can be conveniently injected; secondly, the depth of the wound can be measured through the scales of the administration tube; the medicine discharging from the tail end of the third administration tube is more uniform, and the gel surface is smoother when the administration tube is withdrawn, so that the wound healing is facilitated; fourthly, the wound needs to be debrided before the medicine is taken by the external medicine, the time is needed, when the aseptic operation is carried out, the gravity center of the medicine delivery system moves downwards and is vertically placed on a table top more stably, the injector is prevented from falling, and the convenience of the operation is increased.

Background

The medicine feeding tube and the medicine feeder of the existing external medicine feeding device are in interference fit through the elastic material property of plastics, but the connection part lacks an effective fixing structure, and the gel has the characteristic of difficult flowing, so that the medicine pushing plate has overlarge thrust during use, and the medicine feeding tube is very easy to fall off. Simultaneously, in the process of dispensing and when disinfecting the wound before administration and operating such as debridement, medical personnel need to hold the administration device in real time to avoid the medicine to topple over, use and inconvenience.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an external wound device of dosing, fundamentally has solved above-mentioned problem, and it has advantages such as simple structure is compact, convenient to use is swift.

In order to achieve the above purpose, the utility model provides a following technical scheme: this external wound device of dosing includes that sliding fit gives medicine ware subassembly and pushes away the medicine subassembly, sets up the pipe of dosing at ware subassembly front end of dosing, pushes away the medicine subassembly including pushing away the powder column, set up pushing away the powder stopper pushing away the powder column front end, set up at the tablet pushing away of pushing away the powder column rear end, give medicine ware subassembly include that the barrel sets up the ware connecting portion of dosing at the barrel front end, set up at the barrel rear end with push away tablet complex accessory plate, its technical essential is: the administration tube is arranged at the front end of the administration device component through a thread structure, and the medicine pushing plug is in a waist-round shape.

Furthermore, the administration tube comprises a connecting cap in threaded fit with the administration device connecting part, an administration tube hard part and a sealing ring which are limited in the connecting cap, and an administration tube flexible part integrated with the administration tube hard part, wherein a blocking platform is arranged on the administration device connecting part, and the sealing ring is limited between the blocking platform and the administration tube hard part.

Furthermore, the flexible part of the administration tube is provided with scale marks.

Furthermore, the tail end of the administration tube is of an inclined plane shovel-shaped structure.

Furthermore, an adsorption structure is arranged on the medicine pushing plate.

The utility model has the advantages that: the administration tube is screwed on the connection part of the administration device through the connection cap, the administration tube can be firmly installed on the front end of the barrel body, and accidental falling of the administration tube caused by the use of the medicine pushing assembly is avoided. Meanwhile, due to the adoption of a standard screw structure, the expandability of the administration device can be effectively improved, and the multipurpose use is realized by matching with various administration pipe components.

The weight of the medicine pushing plate is increased, and the center of gravity of the medicine feeding system is moved downwards and vertically placed on a table top to be more stable during aseptic operation. Furthermore, through setting up adsorption structure, like magnet, rubber suction cup, can adsorb the ware of dosing on the horizontal plane wholly, avoid the medicine to empty.

The administration tube comprises a hard portion and a flexible portion which are of an integrated structure, hot melting forming can be adopted between the hard portion and the flexible portion, machining efficiency and connection firmness are effectively improved, and meanwhile sealing performance is guaranteed. Wherein, the flexible part is marked with a graduated scale which can measure the sinus depth when the sinus is dosed.

The front end of the administration tube is of an inclined surface structure, so that the medicine discharging area is larger and more uniform, and the medicine can be prevented from being blocked in the tube. The shovel-shaped structure can assist the dressing to smoothly cover the wound surface when the gel dressing is given.
