Description
[technical field]
This utility model relates to be introduced in body cavity or the reservation medium, and for example the apparatus of medicine refers to a kind of disposable cavity/canal drug administration device that has sealing gasket especially.Be mainly used in human or animal's cavity/canal drug administration.
[background technology]
Disposable cavity/canal drug administration device is similar to syringe, comprise sealing cap 1 ' as shown in Figure 4, deposit cartridge case 2 ', push away medicated cushion 3 ' and pushing ram 5 ', depositing cartridge case 2 ' main body is hollow cylinder, front end is a medicine outlet, the rear end is the pushing ram import, the middle part is a drug storage portion, and according to different medicines, the medicine outlet bore can be less than or equal to the drug storage portion internal diameter at middle part.Sealing cap 1 ' will be deposited cartridge case sealing so that the medicine that stores in depositing cartridge case can effectively be deposited depositing the cartridge case front end; Pushing ram 5 ' main body is a column structure, cross section generally is a cross, front end is fixed with one and pushes away medicated cushion 3 ', and this pushes away the approximate straw hat of medicated cushion, and the outside is an annulus, the middle part is hollow convex edge, push away medicated cushion and can also be the hollow cylinder of head sealing, the described medicated cushion that pushes away uses and has certain elastic material to make, and its external diameter is a bit larger tham deposits the cartridge case internal diameter, with depositing cartridge case is interference fit, relies on the strain of its outer edge to realize it and deposits sealing between cartridge case 2 '.Pushing ram 5 ' pushes away medicated cushion 3 ' and forward medicine is released medicine outlet, because of pushing away medicated cushion 3 ' external diameter greater than depositing cartridge case 2 ' internal diameter, can make the people feel that friction is big when advancing, and advances difficulty; On the other hand, deposit cartridge case and generally adopt injection mo(u)lding, because of its main body is a strip hollow cylinder body structure, in order to withdraw from core rod smoothly, the bore of rear end can be slightly larger than front end during production, causes and deposits slightly taper of cartridge case.The structure of this slightly taper makes that push away medicated cushion has to strengthen external diameter and deacclimatize its bigger inlet, causes friction to increase and friction can be more and more big in propelling, feel is uncomfortable, and this is its shortcoming.
[summary of the invention]
At the shortcoming of prior art, the less disposable cavity/canal drug administration device that has sealing gasket of friction when the purpose of this utility model is to provide a kind of favorable sealing property and propelling.
The technical scheme that its technical problem that solves this utility model adopts is: comprise sealing cap, deposit cartridge case, push away medicated cushion, and pushing ram, sealing cap will be deposited the sealing of cartridge case medicine outlet in depositing the cartridge case front end, depositing cartridge case is hollow column structure, pushing ram injects deposits that its front end pushes away medicated cushion in the cartridge case, pushing away medicated cushion is the hollow structure in head sealing middle part, the pushing ram front end has a convex edge and the middle part hollow parts that pushes away medicated cushion to match, can inject and to push away medicated cushion in this hollow parts and push the place ahead to, pushing ram and push away medicated cushion and form moving sets and connect to depositing cartridge case, it is characterized in that: deposit have a step will deposit cartridge case in the cartridge case to be divided into before, two sections of backs, the back segment internal diameter is greater than the internal diameter of leading portion, in depositing the cartridge case back segment, be fixed with a sealing gasket, the sealing pad is a hollow cylinder, its outer cylinder is formed interference fit with the inner cylinder (endoporus) of depositing the cartridge case back segment, form sealing state, pushing ram can pass sealing pad endoporus and form moving sets with the sealing pad and connect; The described internal diameter that pushes away the external diameter of medicated cushion greater than sealing gasket, described sealing gasket front end has a step to make the sealing gasket front end form a recess, the internal diameter of this recess is with to push away the medicated cushion outer suitable, pushing away medicated cushion is positioned in this recess, the outer and this recess endoporus that push away medicated cushion are formed interference fit, form sealing state; Push away medicated cushion and deposit cartridge case composition matched in clearance;
Because the sealing gasket outer cylinder is a sealing state with depositing cartridge case back segment inner cylinder, and sealing gasket front end recess is a sealing state with pushing away medicated cushion, and sealing cap will be deposited the sealing of cartridge case front end medicine outlet, make the drug storage portion of this disposable cavity/canal drug administration device be in sealing state, interior powder charge thing can effectively be preserved, during use the reeve of pushing ram front end convex edge is pushed away in the hollow convex edge, medicated cushion middle part, can promote forward pushing away medicated cushion, is matched in clearance because of pushing away medicated cushion with depositing cartridge case, interference fit compared with prior art, its friction is quite little, uses comfortable feel.
The beneficial effects of the utility model are: both solved sealing, the inconvenience that friction is brought too greatly when having solved administration again.Solved the contradiction of sealing and friction, friction is little when favorable sealing property and propelling, comfortable feel.As the disposable cavity/canal drug administration device of human body or animal, medicine directly can be loaded on again and deposit in the cartridge case, save packing materials.Solved administrator when depositing liquid, semifluid, solid because bad, the seepage of sealing, moisture absorption phenomenon.
[description of drawings]
The utility model will be further described below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that this utility model is deposited cartridge case and sealing cap split structural representation.
