Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a resin-molded drip container, and more particularly to a ventilation structure for the container.

[0002]

2. Description of the Related Art FIG. 6 shows an example of a conventional drip container. This drip container 1 is provided with an opening cap 2 on the upper side and a hook 3 on the lower side. When used, the hook 3 is suspended with the hook 3 on the upper side, and the opening cap 2 is disposed on the lower side to be connected to an infusion tube. ing.

Since the drip container 1 is closed except for the opening cap 2 (because there is no opening), the atmospheric pressure in the bottle decreases when the infusion is continued to be infused. Therefore, in the medical field, the ventilation needle 5 is inserted into the lower end portion (hook side; the same applies hereinafter) of the drip container 1 to maintain ventilation with the atmosphere.

[0004]

By the way, the operation of applying atmospheric pressure to the drip container as described above is simple, but is often troublesome in the actual medical field. This is because it is necessary to prepare a ventilation needle, wipe the portion into which the needle is inserted with alcohol to disinfect it, and separate and discard the ventilation needle after use.

This ventilating needle is a thick needle used during blood transfusion and is not a dedicated needle for drip. Therefore, it is necessary to prepare a ventilating needle in advance when initiating infusion, and the time for searching for the needle may be bothersome during busy times. Also, the drip container must be disinfected when the needle is pierced. This is because if the surface of the container is dirty, bacteria may be sent into the body.Although wiping with absorbent cotton soaked with disinfectant alcohol is a routine routine, there are work steps such as management of absorbent cotton and alcohol liquid. It is desirable to reduce the increase as much as possible.
This is because, even if the work is simple, if the number of work steps increases, it may easily lead to accidents in other aspects. Moreover, after the drip infusion, the ventilation needle must be separated, but it may be psychologically troublesome to dispose of it separately from absorbent cotton and other general waste, and it is rare that the separation treatment is not thoroughly performed at the actual medical site. is not.

Therefore, an object of the present invention is to ensure the air permeability of the drip container without using a ventilating needle.

[0007]

In order to achieve the above object and achieve the object, a drip container according to the present invention is provided with a recess at the lower end of a resin-molded drip container, and a folding claw is projected on the bottom surface of the recess. When the folding claws are arranged, a minute opening is formed on the bottom surface of the recess. In addition, the recess may be covered with an easily peelable thin seal.

[0008]

According to this drip container, by pushing down the folding nail, a minute opening is formed at the base end portion of the folding nail, and the air permeability is secured. The folding claws rise from the bottom of the recess, and the bottom of this recess does not come into contact with human hands when carrying,
Hygiene can be ensured by disinfecting it during manufacturing.
Also, if a thin seal is stretched over the recess, hygiene is significantly improved.

[0009]

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 shows an example of the drip container according to the present invention. This drip container 10 has the same basic shape as a conventional drip container, and has an opening cap 14 on the upper part of a resin-molded container body 11 and a hook 16 on the lower end. Further, a recess 20 is provided at the lower end of the container body 11 as shown in FIG.
The folding claw 23 connected to is provided.

The folding claw 23 is fixed to the lower end surface 21, and the lower end surface 21 can form an opening when the folding claw 23 is pushed down. This opening may have any shape such as a slit or a small circular hole. For example, as shown in FIG. 2, a cut (thin line) 2 is formed on the bottom surface 21.
5 may be provided, and when the folding claw 23 is pushed, the cut 25 is opened (broken) to ensure ventilation.
This is a structure similar to a so-called ring pull in canned beverages, but the opening according to the present invention does not need to be wide open, so that even a slit that can partially form a slit line can sufficiently function.

In this recess 20, as shown in FIG.
A thin sealing material 28 such as cellophane is stretched to form the recess 20.
It is desirable to prevent bacteria from adhering to the wall surface of. In this case, the length dimension of the folding claw 23 is set so as not to project outside the outer peripheral general surface 29 of the recess 20. It suffices that the sealing material 28 prevent invasion of germs and can be easily broken (or peeled) during use. Therefore, in addition to using a resin seal material or paper seal material that can be easily broken, an easily peelable adhesive is used so that the sticking surface of the outer periphery of the seal can be easily peeled off, and a seal material of appropriate rigidity is used. To do. When the peeling property is good, the breakability of the sealing material itself does not matter.

Therefore, according to the drip container 10, when the container body 11 is hung upside down with the hook 16 facing upward,
By removing the sealing material 28 located on the upper side of the container body 11 to expose the folding claw 23 and pushing down the folding claw 23, the ventilation opening can be secured.

The shape of the ventilation opening does not matter. For example, as shown in FIG. 4, when the folding claw 30 is pushed down, the minute circular holes 31
This is because the slits (regardless of the number), the slits, and the openings having an appropriate shape may be exposed. The shape and material of the folding claw and the fixed relationship between the folding claw and the bottom surface of the recess are not particularly limited. When the folding claws (23, 30) are pulled (or when pushed down)
The reason is that the ventilation opening may be exposed.

Therefore, the folding claw may be pulled and peeled off similarly to the conventionally known ring pull for canned beverages, and in this case, the resin further fixed to the lower side of the bottom surface to be peeled off. A bottom surface may be provided and a minute opening may be provided on the fixed bottom surface. Also, folding nails (23, 30)
The bottom surface material that supports the lower end of the container need not be a resin material that is continuous with the container body 11, but may be a sealing material such as resin, paper, or metal that pushes down (or pulls out) the folding claw.
The structure may be such that the sealing material comes off to expose the ventilation opening when exposed. In this case, the folding claw peels off the sealing material seal that closes the ventilation opening, but since the disinfectant can be applied to the back surface of the sealing material seal in advance, the recess 20 is sealed. It is not necessary to particularly provide the sealing material 28 to be used.

As described above, in the drip container 10 according to this embodiment, the folding nail 23 (30) is provided in the recess 20 and the folding nail 2 is formed.
Since 3 (30) is pushed down (or peeled off) to secure the ventilation opening, the drip work can be performed without using a ventilation needle, and the burden on the medical staff can be reduced. In addition, since it is not necessary to use a ventilation needle unnecessarily, the risk (psychological burden) of cuts and nosocomial infections can be significantly reduced. Since it is only necessary to provide a recess and a folding claw in a part of the conventional drip bottle, the amount of resin used does not increase, and the molding cost can be maintained at the current state.

If the ventilation opening is simply provided, it is sufficient to provide the opening and the lid at appropriate portions of the container body 11, but if the portion to be the protrusion is provided on the bottle surface, the carrying efficiency becomes poor. Further, providing a lid (for example, a cap) increases the bottle cost. Further, if the lid is loosened, another problem such as leakage of infusion occurs. Therefore, it is desired that these sealing lids are not easily opened due to vibration during transportation or a mistake in handling, and the folding claws are configured to rise from the bottom surface of the recess.

It is sufficient that the position of the recess is such that it does not break during transportation and transportation and is easy to open when the container body 11 is hung upside down, and the lower end portion (upper end portion when inverted).
The arrangement position is not particularly limited as long as it is an appropriate position. For example, the hook 16 may be disposed on the lower end surface. This is because even the lower end surface (lower surface) does not affect the opening / closing operation with a finger. That is, the positions where the recesses and the folding claws are arranged depend exclusively on the bottle molding cost and the general rigidity of the bottle.

Although not easy to use, as shown in FIG. 5, a ventilation tube 41 is raised from the recess 40, a cap 42 is placed on the ventilation tube 41, and a sealing seal 44 is attached to the recess 40. It may be a structure to wear. in this case,
An inner diameter of the ventilation tube 41 of 1 to 2 mm is sufficient. Also in this case, the sealing seal 44 is not always necessary. This is because it is sufficient that the cap 42 portion is sufficiently sterilized.
