Description

Sterile funnel

Technical Field

The utility model relates to a funnel, in particular to a sterile funnel.

Background

Hemodialysis (HD) is one of the alternative treatments for the kidney of patients with acute or chronic renal failure. The method comprises the steps of draining blood in vivo to the outside of the body, enabling the blood and electrolyte solution (dialysate) with similar body concentration to be inside and outside one hollow fiber through a dialyzer consisting of a plurality of hollow fibers, and carrying out substance exchange through dispersion, ultrafiltration, adsorption and convection principles, so as to remove metabolic waste in the body and maintain the balance of electrolyte and acid and alkali; at the same time, the excess water in the body is removed, and the whole process of purified blood reinfusion is called hemodialysis. When hemodialysis is carried out, the dialysate is divided into AB two liquids, glucose powder needs to be added into the liquid A before the diabetes patient uses the AB dialysate to carry out hemodialysis so as to supplement glucose lost by dialysis and avoid hypoglycemia; calcium powder is added into the solution A before the low-calcium patient uses the composition, so as to adjust the concentration of calcium in hemodialysis and control the calcium in the patient body within a normal range.

The existing AB dialysate is stored in a common plastic barrel. When adding glucose powder, calcium powder or other powder in toward the dislysate, generally directly pour powder into the dislysate from the bung hole of dislysate directly, because powder is bagged, bad operation, powder pours into the bung hole outside very easily, cause the waste, some medical personnel are convenient for the operation, can use ordinary funnel to assist in the powder pours into the dislysate occasionally, but still can not avoid the powder to pour out outside the bung hole completely like this, and powder exposes in the air, can contact with foreign matter or dust in the air, thereby pollute the dislysate, there is the safety problem.

SUMMERY OF THE UTILITY MODEL

The technical problem to be solved by the utility model is as follows: the utility model provides an aseptic funnel, at the in-process of adding powder, not only can prevent that powder from pouring out the bung hole outside, avoid extravagant, can also avoid powder to expose in the air and dust or foreign matter contact, keep aseptic environment.

In order to solve the technical problems, the utility model adopts the following technical scheme:

aseptic funnel, including fighting and intubate, fight and be the toper and upwards extend and go out the connecting portion that form by the big port edge of fighting, connecting portion are equipped with the bottle of placing that is used for accomodating the powder bag, place the bottle and fight the intercommunication, the miniport and the intubate intercommunication of fighting.

As a further improvement of the above technical solution:

the placing bottle comprises a barrel body and a barrel cover, one end of the barrel body is inserted into the connecting part, the other end of the barrel body is connected with the barrel cover, and the barrel cover is slidably sleeved on the barrel body; the barrel cover is a shell with a hollow inner part and an opening at the bottom, the inner wall of the barrel cover is provided with internal threads, the outer surface of the barrel body is provided with external threads, and the end head of the barrel body is inserted into the barrel cover from the opening of the barrel cover and is in threaded connection with the barrel cover; a clip for clamping the powder bag is arranged in the cylinder cover. After the clamp gripped the medicinal powder bag, the cylinder cover was continuously screwed into the cylinder body, which not only could prevent the medicinal powder from contacting the dust or foreign matter in the air to the sealed cylinder body and the hopper, but also the medicinal powder bag could be continuously close to the hopper, so that the medicinal powder could be rapidly added into the dialysate to shorten the time.

Furthermore, the inner wall of the connecting portion is provided with a clamping groove, the clamping groove is formed by extending the non-connecting end edge of the connecting portion towards the inside, the barrel is provided with a clamping block, and after the barrel is inserted into the connecting portion, the clamping block is clamped into the clamping groove.

The barrel cover is rotated, the medicine powder bag continuously moves towards the hopper, and under the extrusion action of the barrel cover, the bag body is punctured by the sharp tips of the sharp teeth, so that medicine powder in the medicine powder bag can flow out of the medicine powder bag, and finally flows into dialysate through the hopper and the insertion tube.

Furthermore, the side surface of the barrel is provided with a placing opening and a door for covering the placing opening, one side of the door is hinged with the barrel, and the other side of the door is connected with the barrel through a buckle. After the door is opened, the medicine powder bag can enter the placing bottle through the placing opening; after the door is closed, the placing opening is sealed, foreign matters and dust can not enter the dialysate through the sterile funnel, the medicine powder bag is guaranteed to be punctured by the sharp teeth, and the process that medicine powder flows into the dialysate can be kept in a sterile state all the time, and the safety of the dialysate is guaranteed.

Furthermore, the outer wall of the barrel body protrudes with a mounting ring, the mounting ring is positioned at the lower part of the placing opening, a notch is arranged at the position of the mounting ring opposite to the placing opening, one side of the door is hinged with the edge of one side of the notch, the other side of the door can be opened or closed at the edge of the other side of the notch, and a gap is reserved between the door and the barrel cover after the door is closed. The mounting ring protrudes out of the outer wall of the barrel body, so that the door can be sealed after being closed, foreign matters and dust are prevented from entering the door, and a gap can be reserved between the door and the barrel cover, so that the barrel cover can slide on the barrel body smoothly.

The utility model has the beneficial effects that:

the bung hole of dislysate is inserted to the intubate, and the medicine powder bag is accomodate in placing the bottle, and in powder added the dislysate through fighting, whole process placed the bottle and all is connected with connecting portion, can not only prevent that powder from pouring out the bung hole outside, avoids extravagant, can also avoid powder to expose in the air with dust or foreign matter contact to keep aseptic environment, guarantee the safety of dislysate.
