[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a suppository injector. More specifically, it is easy to insert a solid suppository, does not require the use of vinyl gloves during use, is less painful to the patient, and completely infects the injector during administration. It is a disposable suppository inserter that can be prevented.

[0002]

[Prior art]

 Although suppository medication is currently increasing clinically, when administering a solid suppository, the patient is usually placed in the lateral position and a nurse wearing vinyl gloves pushes it directly into the patient's anus with his fingers. To prevent the discharge of the suppository inserted by anal stimulation, the suppository is held for a while as it is, or the suppository is inserted as deeply as there is in the rectum with a cotton swab or the like, and the medication is properly devised.

However, these methods are cumbersome and time-consuming to administer, and not only cause some pain to the patient, but also recently, injecting AIDS or methicillin-resistant staphylococcus aureus to the injector during administration. As it has become a social problem, there are many problems and dangers in the administration method of solid suppositories.

[0004]

[Problems to be solved by the device]

 Paying attention to the recent increase in clinical suppository medication, it is easy to handle when administering solid suppositories mainly in hospitals and the like, and it is not necessary to wear vinyl gloves during use, but the patient's pain is less In this case, it is intended to provide a disposable suppository injector that can prevent the infector from being infected.

Particularly, recently, a malignant pathogenic bacterium or viral infection has become a social problem in a hospital or the like, and therefore it is suitable for this purpose.

[0006]

[Means for Solving the Problems]

 The present inventor has focused on the fact that there are various problems as described above when mainly administering a solid suppository, and it is possible to administer the drug easily by a method like a syringe, and the physical and psychological distress of the patient is extremely high. As a result of various studies on small suppository injectors, a cylindrical injector loaded with a solid suppository was provided with a plurality of longitudinal cracks in the outer cylinder, and when a plunger was pushed into the body, a snake was just a frog. The suppository can be gradually inserted into the rectum without friction with the inner wall of the rectum so that the frog gradually moves in the esophagus of the snake when swallowed, and the tip of the injector is thinned and the rubber is The inventor arrived at the present invention based on the idea that the pain can be remarkably reduced by attaching such a cover.

That is, the suppository injector body 1 is composed of an outer cylinder 2, a sucker 3, and an outer cylinder cover 4, and an opening 5 is provided at the tip of the outer cylinder 2, and a cylindrical outer cylinder front portion connected to the opening 5. 6, an outer cylinder middle part 7 whose inner diameter gradually increases, a cylindrical outer cylinder rear part 8 with a large inner diameter, and projections 9 and 9'on the end of the outer cylinder in order, and from the tip of the outer cylinder to the middle part. Alternatively, a plurality of fissures 10 and 10 'are provided in the longitudinal direction toward the rear part, and the sucker 3 includes a guide 11 and a plunger 12, and the inner surface of the outer cylinder and the guide or plunger are always kept airtight. There is no need to cover the cover 4 with a rubber or elastic sheet from the front end to the middle part or the rear part of the outer cylinder. When the rear end of the plunger is pushed in, the suppository loaded between the outer cylinder and the sucker is not necessary. Moves forward and the splits 10 and 10 'of the outer cylinder are pushed open, Is a suppository injector having a structure of being injected into the body from the tip of the outer cylinder.

The present invention will be described in detail below.

The main body 1 of the suppository injector of the present invention comprises an outer cylinder 2, a sucker 3 and a cover 4. The outer cylinder 2 pushes the suppository loaded in the rear part of the outer cylinder into the plunger, so that when the snake drinks the frog, the frog gradually moves in the esophagus of the snake, so that the inside of the outer cylinder is moved. In order to make it transferable, it is preferable to use a material having high elasticity or plasticity from the front part of the outer cylinder to the middle part or the rear part. Therefore, a tube made of soft low-density polyethylene, soft plastics such as soft polyvinyl chloride resin, or rubber is preferable.

In addition, it is preferable for use that the injection state of the suppository can be confirmed from the outside, and transparent plastics are preferable from the viewpoint of moldability. In addition, it is not necessary to use a material with high elasticity or plasticity in the rear part of the outer cylinder because it is almost not necessary to expand the inner diameter when injecting suppositories, but plastic is preferable from the viewpoint of moldability, and the front part and the middle part are preferable. A material that is rich in elasticity or plasticity may be used for, and a hard material may be used for the rear portion.

The sucker 3 is a member used for pushing the suppository loaded inside the outer cylinder. The material is not particularly limited, but plastics are preferable from the viewpoint of moldability. In addition, the cover 4 facilitates insertion of the distal end into the anus, and since there are many longitudinal cracks in the distal end and front part of the outer cylinder, the cover 4 comes into contact with the suppository during expansion and contraction. It is used to pinch the inner wall of the rectum or to relieve discomfort, and a material with low friction and high elasticity or plasticity is preferable. For example, rubber or a material rich in elasticity and / or plasticity is preferable. To facilitate insertion of the tip of the injector into the anus, it is also preferable to partially use a fluororesin film or the like if necessary.

Next, the present invention will be described in detail with reference to the drawings. FIG. 1 shows a front view of one embodiment of the suppository injector of the present invention, and FIGS. 2 (a) and 2 (b) show a left side view and a front view of an injector barrel, respectively.

The outer cylinder 2 is composed of a tube of soft low-density polyethylene resin having a high elasticity and plasticity even at room temperature and a thin wall thickness, and has an opening 5 at the tip and a cylindrical outer cylinder with a small inner diameter connected to it. A portion 6, an outer cylinder middle portion 7 whose inner diameter is gradually thickened, a cylindrical outer cylinder rear portion 8 having a large inner diameter, and projections 9 and 9'on the end of the outer cylinder are provided in order. The opening at the distal end and the portion adjacent to the opening should preferably have a smooth crimped shape in order to facilitate the insertion of the injector into the body and reduce the pain of the patient.

An opening 5 is provided at the tip of the outer cylinder 2, and the inner diameter of the front portion of the outer cylinder connected to the outer cylinder 2 is preferably generally the same as the opening, and the inner diameter is gradually increased by connecting to the opening. The outer cylinder middle part 7, the cylindrical outer cylinder rear part 8 having a large inner diameter connected to the outer cylinder middle part 7, and the end of the outer cylinder are sequentially provided with projections 9 and 9 '. Further, the outer cylinder is provided with four cracks 10 and 10 'in the longitudinal direction from the front end to the middle part or the rear part. The number of cracks in the outer cylinder may be further increased, or more cracks may be provided only in the tip portion so that the tip portion looks like a brush tip. The crack may extend from the tip to the middle portion, or may extend from near the rear end of the outer cylinder.

The material of the sucker 3 is a polypropylene resin molded body, which is composed of a guide 11 and a plunger 12. Further, a pushing projection 13 is provided at the end of the plunger so that the medicine can be pushed in easily. preferable. The material of the suction element is not particularly limited, and a wide range of materials can be used, but polypropylene resin and the like are preferable in consideration of moldability and economic efficiency. Since the suppository is usually a solid drug, it is not always necessary to keep airtight between the guide of the sucker or the plunger and the inner surface of the outer cylinder. However, when using a soft suppository that may leak inside the injector or at the rear of the guide when using a jelly-like drug, it is necessary to make the space between the plunger and the inner surface of the outer cylinder airtight. It is preferable that the length of the plurality of cracks provided in the length direction from the tip of the outer cylinder to the middle portion is short, and it is preferable that the cracks end at the first partial position of the middle portion.

FIG. 1 shows the overall shape of a suppository injector in which the suction member and the cover 4 are attached to the outer cylinder shown in FIG. 2 as described above. The cover 4 is made of a thin elastic rubber tube. ing. When the tube is hung from the tip of the outer cylinder to the middle part or the rear part, due to its elasticity, four crevices 10 and 10 'in the length direction, which are provided from the tip of the outer cylinder to the middle part, are tightened from the outside and the intervals are considerably wide. It is narrowed. Also, it is preferable to attach the cover so that the tip of the cover is slightly longer than the tip of the outer cylinder. If necessary, if the tip portion 13 of the cover is made of a sponge-like tissue, jelly, water, edible oil, or glycerin may be used. It is more effective when a lubricant such as

3 (a), (b), (c) and (d) are sectional views showing the action of injecting a suppository 15 using the suppository injector of the present invention shown in FIG. . (a) shows a state in which a solid suppository is loaded inside the suppository injector. The solid suppository 15 is usually in the shape of a bullet with a sharp tip. When loading, the sucker 3 attached to the outer cylinder 2 of the injector is pulled out backward, and the suppository is inserted inside the outer cylinder, then again. Insert the sucker into the outer cylinder.

Next, FIG. 3 (b) shows a state during suppository injection, which is a stage before the tip of the suppository still reaches inside the body. When injecting a drug, insert the tip of the outer cylinder, whose tip is covered with a cover, gently into the anus, and once the tip reaches the inside of the anal sphincter, place your fingers on the projections 9 and 9'at the rear end of the outer cylinder. When the rear end 13 of the sucker is gradually pushed, the suppository is pushed by the plunger 12 of the sucker and moves forward. The outer cylinder has four cracks in the length direction, and since it is a thin tube of low-density polyethylene resin that has high elasticity and plasticity even at room temperature, as the drug moves forward, the middle of the outer cylinder The solid medicine gradually moves forward, just as the frog moves inside the esophagus of the snake when the inside diameter of the front part and the front part expands and the snake swallows the frog. At this time, the cover behaves as if it were seamless and extensible. It also has the function of promoting the movement of the drug and keeping the surface of the front part of the outer cylinder opened by the expansion of the cracks smooth. Furthermore, when inserting the tip of the outer cylinder into the anus, if a small amount of a lubricant such as jelly, water, edible oil or glycerin is applied to the tip of the rubber cover, the frictional resistance is significantly reduced. It is also effective for ease of insertion and reduction of patient's pain. The rubber cover beyond the tip of the outer cylinder is in a small contracted state until the tip of the medicine reaches that portion, but when the tip is pushed from the rear part, the opening easily expands and passes the medicine. Let

FIG. 3C shows a state in which the tip of the suppository reaches the inside of the anal sphincter from the anus and is injected into the rectum. The drug in the outer cylinder is gradually pushed by the sucker, moves in the front part of the outer cylinder, and is injected into the rectum through the opening at the front end. At this time, the inner diameter of the tip is greatly expanded and the gap between the cracks 10 and 10 'is also wide open, but since the outside is covered with a smooth rubber cover, the unevenness directly affects the inner wall of the rectum. It does not make you feel uncomfortable. The suppository injector of the present invention covers the surface of the injector with a film having smoothness and elasticity in order to facilitate the injection and reduce the pain of the patient. The most significant feature of the present invention is the provision of cracks.

FIG. 3 (d) shows a state immediately before the injection of the suppository is completed and the injector is pulled out from the anus to the outside. When all of the drug is injected into the rectum and the rear end of the shell-shaped suppository leaves the tip of the injector and cover, the injector returns to its pre-suppository state. At this time, a particular problem is that the inner diameter of the front part of the expanded outer tube contracts rapidly and the gap between the cracks on the surface of the outer tube also contracts rapidly, so that the inner wall of the rectum is not pinched. It is necessary to fully consider the thickness and elasticity of the cover. After injection of the drug, the tip of the outer cylinder is contracted and thinned, so it can be easily pulled out from the anus, and can be easily discarded by putting it in a pre-installed vinyl bag and sealing it.

When the suppository is not solid but jelly-like, it is preferable that the crack in the length direction of the outer cylinder is from the tip to the beginning of the middle portion, and to prevent leakage to the outside during drug injection, An airtight structure is preferably provided between the inner surface of the outer cylinder and the plunger of the sucker. The injection method is almost the same as for solid drugs.

FIG. 4 is a front view of another embodiment of the suppository injector of the present invention, and FIGS. 5 (a) and 5 (b) are a left side view and a front view of the outer cylinder of the injector, respectively. Indicates.

The outer cylinder 2 is made of a soft vinyl chloride resin tube that has high plasticity and considerable elasticity even at room temperature, and has a thin wall thickness. The middle part and the rear part are made slightly thicker to reinforce the mechanical properties. . This is because the physical properties of the soft vinyl chloride resin were taken into consideration, and the number of cracks provided in the length direction from the tip of the outer cylinder to the middle or rear was eight, and only the tip was the middle of each strip. There is another crack in the area. This is to facilitate tip injection when using the injector and to further alleviate patient distress. Other structures and functions of the outer cylinder and the sucker are almost the same as those of the injector shown in FIGS.

The cover 4 is made of a thin tube of a soft low-density polyethylene film, and is made of a material having the highest plasticity and elasticity at room temperature as the low-density polyethylene film, but it does not have high elasticity like rubber in advance. A film is formed into a shape that fits the outer cylinder of the injector, and the part that covers the tip and front of the outer cylinder has a length from the tip so that it easily tears when the inner diameter of the tube expands. There are multiple perforations in the vertical direction. Therefore, when the tip of the shell-shaped suppository is pushed by the sucker and enters from the middle part of the outer cylinder to the front part, and the inner diameter of the polyethylene film cover expands as the inner diameter of the front part expands, the polyethylene cover expands easily. If necessary, the perforation can be torn into strips and the suppository can be injected smoothly into the rectum. When a suppository is injected into the entire rectum and leaves the tip of the injector, the front part of the outer cylinder contracts, but if a soft vinyl chloride resin that has extremely high plasticity at room temperature is selected, cracks in the length direction will occur. When the space between the two contracts, nothing like pinching the inner wall of the rectum occurs.

Furthermore, when the tip of the injector is inserted into the anus, a small amount of a lubricant such as jelly, water, edible oil or glycerin is preferably applied to the tip of the polyethylene film cover to reduce friction resistance. However, it is effective in facilitating the insertion and reducing the pain of the patient, and the disposal method after use is almost the same as the injector shown in FIG.

[Effect of device]

 Since the suppository injector of the present invention also has an injector cover that is highly flexible and elastic at room temperature, it is easy to handle when a solid suppository is mainly administered in hospitals and the like, and it is not necessary to wear vinyl gloves during use. Moreover, it is a disposable suppository injector with less pain for the patient. Further, it is also effective in preventing the infection of malignant pathogens or viruses such as in hospitals, which have become a social problem recently.
