Abstract

PROBLEM TO BE SOLVED: To stably and safely such pituita by equipping a suction head part onto a container and an elastic tube laterally extended communicating with the container to constitute a pituita aspirator used for clean the snuffles of infants. SOLUTION: On use, a nursing person such as a mother holds an infant in an upward facing posture by a hand. The she/he holds a suction piece 18 of an elastic tube 17 in her/his mouth, the container 11 part of the pituita aspirator 10 in the other hand, and makes a suction port 14a of the suction head 14 about on in the naris of the infant. On that condition, the nursing person performs sucking through the suction piece 18. When the pituita sucked from the naris of the infant has low viscosity, the pituita is passed through a communicating passage equipped so as to open to the container 11 side and guided into the container 11. At that time, the nasal discharge is effectively prevented from being turned into an inner opening of an elastic tube attaching/detaching part 15 by the communicating passage to make the pituita be securely stored in the container 11.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a small nasal suction device used by an assistant such as a mother for an infant or the like.

[0002]

2. Description of the Related Art Conventionally, the following is used as a nasal suction device for removing a stuffy nose from a baby. That is, such a nasal suction device is provided with a contact piece at one end of an elongated elastic tube, and this contact piece is slightly applied to the nostril of an infant, and the helper holds the other end of the tube to the mouth. It is designed to draw in breath from the tube and out of nasal discharge. In such a suction device, nasal discharge may directly enter the mouth of the caregiver, which is not only unsanitary but also dangerous because a strong negative pressure is momentarily applied to the nostrils of the infant.

Therefore, a nasal suction device as shown in FIG. 6 is also known. In the figure, a suction device 1 has a container 6 and first and second tubes 3, 3, each having one end inserted into the container 6 via a lid 2 and arranged to extend above the container 6. The contact piece 5 is attached to the other end of the second tube 4.

In such a nasal aspirator 1, a user (assistant) applies the contact piece 5 to the nostril of an infant, applies the other end of the first tube 3 to the mouth, and aspirates. Due to the negative pressure applied to the nostrils, the nasal discharge of the infant is sucked out, and the nasal discharge passes through the second tube 4 and accumulates in the container 6. Accordingly, the sucked nasal discharge does not enter the mouth of the caregiver, which is sanitary. Further, it is possible to effectively prevent sudden strong negative pressure from being applied to the nares of the infant through the container 6.

[0005]

However, when using such a nasal aspirator 1, the caregiver holds the baby with one hand and holds the contact piece 5 of the first tube 3 on the other hand. It is necessary to hold it in your hand and attach it to the nostrils of infants.
In such a state, the container 6 swings unstablely between the two tubes 3 and 4 and is difficult to use. However, since both hands of the caregiver are occupied, this cannot be suppressed. That is, since the container 6 swings between the two long tubes 3 and 4, the contact piece 5 is stably prevented from hitting the nostrils, and there is a problem that the usability is extremely low.

The above-mentioned nasal aspirator 1 aspirates nasal secretion through two long tubes 3 and 4 with a container 6 interposed therebetween. As described above, it is possible to prevent an excessive negative pressure from being applied to a nostril of an infant or the like as described above. On the other hand, the suction force acts through two long conduits, and thus a pressure loss due to the long conduit is reduced. It becomes larger and the suction power becomes weaker than necessary. For this reason, there is a drawback that the caregiver must rub the tube 3 with a correspondingly stronger suction force, which places a burden on the caregiver.

The present invention has been made in order to solve such a problem, and it is possible to stably perform a suction operation in which a suction head is applied to a nostril of an infant or the like without burdening a caregiver. It is an object of the present invention to provide a nasal aspirator that can be used safely.

[0008]

SUMMARY OF THE INVENTION According to the first aspect of the present invention, there is provided a storage container for storing nasal discharge, and a storage container provided at an upper portion of the storage container and communicating with the storage container. This is achieved by a nasal aspirator comprising a suction head directly in contact with the nostrils and a resilient tube extending in the lateral direction in communication with the container and having a mouthpiece at the tip.

According to the first aspect of the present invention, since the suction head to be applied to the nostrils of an infant or the like is formed on the upper portion of the container, the caregiver holds the portion of the container by hand. , You can hit the suction head. Accordingly, the holding container is securely held, so that the suction operation can be stably performed. Moreover, the suction power of the caregiver
Since the caregiver is designed to connect the elastic tube and the storage container to be added, the pressure loss is smaller and the suction force applied to the nostrils is prevented from being insufficient compared with passing through two conduits. Is attenuated.

According to the second aspect of the present invention, the storage container is a bottomed cylindrical body having a bottom, and a reduced diameter portion having a predetermined height is provided on an upper portion of the storage container. May be provided with the suction head section continuously provided through the suction head section.

According to a second aspect of the present invention, in the configuration of the first aspect, when the suction head is applied to a nostril of an infant, the reduced-diameter portion maintains a predetermined distance from the suction head. Since it is located, the large-sized container does not interfere with the lips or the like of the baby.

According to a third aspect of the present invention, in the configuration of the first or second aspect, the storage container is provided with a lid portion that is attached to and detached from an upper portion of the storage container, and the lid portion is formed of the storage container. A reduced diameter portion having an inner space that is reduced in diameter from the diameter of the container and extends upward and has an open lower part, and communicates with the inner space of the reduced diameter portion. The elastic tube is provided so as to extend in the lateral direction, and is provided so as to protrude upward from the upper portion of the reduced diameter portion, so as to communicate with the internal space of the reduced diameter portion. And a suction head configured as described above.

According to the third aspect of the present invention, by removing the lid, the container body and the lid having other structures are separated from each other, so that the inside of the container can be easily cleaned.

According to a fourth aspect of the present invention, in the configuration of the first to third aspects, a communication passage communicating with a tip end of the suction head portion extends long in the internal space of the lid portion.

According to the third aspect of the present invention, the nasal passage sucked from the suction head unit is formed by the long communication passage communicating from the distal end of the suction head unit into the internal space of the lid unit. Since the gas passes through the communication passage, the creepage distance from the suction head portion to the attaching / detaching portion of the elastic tube can be increased, and the nasal discharge can be effectively prevented from easily flowing to the elastic tube side.

[0016]

Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings. The embodiment described below is a preferred specific example of the present invention, and thus various technically preferable limitations are added. However, the scope of the present invention particularly limits the present invention in the following description. The embodiment is not limited to these embodiments unless otherwise stated.

FIG. 1 is a schematic perspective view showing the entire nasal aspirator according to an embodiment of the present invention, FIG. 2 is a plan view of the nasal aspirator of FIG. 1 excluding a tube, and FIG. FIG. 4 is a cross-sectional view of the nasal aspirator of FIG.

In FIG. 1, the nasal aspirator 10 includes a housing container 11 for housing the sucked nasal secretion, and a lid 12 that is attached to and detached from the housing container 11. Container 11
Is a container having a bottomed cylindrical body and formed of, for example, plastic having a diameter of about 24.7 mm and a height of about 22 mm. Preferably, the storage container 11 is formed of a light-transmitting or transparent member so that the inside state can be visually recognized from the outside.

As shown in FIG. 4, an attaching / detaching portion 11a is formed on the upper portion of the container 11, and the attaching / detaching portion 11a is formed.
a is formed by, for example, the male screw 11b. On the other hand, the lid portion 12 that is attached to and detached from the storage container 11 is an attachment / detachment portion 12a having an inner diameter slightly larger than the outer shape of the attachment / detachment portion 11a of the accommodation container 11, and for example, is screwed into the male screw 11a. A mating female screw 12b is provided. Further, as shown in FIG. 5, the detachable portion 12a of the lid portion 12 has an inner peripheral wall 12c which enters the inner peripheral side of the detachable portion 11a of the storage container 11, and an outer peripheral wall 12e which is located on the outer peripheral side of the detachable portion 11a. And a sealing means 12 having a circular convex shape protruding toward the opening edge of the container 11 in the region between
d is formed integrally.

Thus, the container 11 and the lid 12 are
The screw portions are easily fixed by screwing, or the fixing is released by removing the screw.
Moreover, when the lid 12 is attached to the container 11,
The sealing means 12d abuts the opening edge of the storage container 11 to close the gap therebetween, so that airtightness can be maintained. Therefore, a sealing effect can be obtained without interposing another member such as a packing between the storage container 11 and the lid 12.

The lid 12 is provided with a reduced diameter portion 13. The reduced-diameter portion 13 includes the container 11 and the lid 12.
This is a portion formed to have a smaller cross-sectional diameter than the lower part of. As shown in FIG. 3, the reduced diameter portion 13 is formed to have a predetermined height L1 from the lower portion of the lid portion 12, and a space S is formed therein as shown in FIG. ing.
A tubular tube attaching / detaching portion 15 is provided to protrude laterally from the reduced diameter portion 13 so as to communicate with the space S. In this embodiment, the tube attaching / detaching portion 15
Extends horizontally from the reduced diameter portion 13, but may have a slight inclination with respect to the storage container 11 as long as it is in the horizontal direction.

On the reduced diameter portion 13 of the lid portion 12, a suction head portion 14 is provided integrally. The suction head 14 has a suction port 14a at the tip, a swelling portion 14b having a substantially spherical or elliptical cross section in the middle, and a narrow neck portion between the suction head 14 and the reduced diameter portion 13. 14c
It has become. The outer peripheral portion of the suction port 14a is large enough to be inserted into the nostril, for example, about 6 mm. This prevents the suction head unit 14 from accidentally entering the nostrils when the tip of the suction head unit 14 contacts the nostrils of an infant or the like. Also,
In this case, since the contact portion is formed with a curved surface, unnecessary stimulation is not applied to the nostrils. Further, a lower end of the suction head portion 14 is provided with a communication passage 16 extending downward in communication with the suction port 14a. As shown in FIG. After passing through S, it opens to the container 11 side below the tube attaching / detaching portion 15.

Thus, as described later, the nasal discharge sucked from the suction port 14a from the suction head section 14
It is guided into the storage container 11 through the communication path 16, and since the lower end opening 16a of the communication path 16 is disposed below the tube attaching / detaching portion 15, they are separated by a long creepage distance. As a result, the sucked nasal discharge is prevented from going around the tube attaching / detaching portion 15 side.

As shown in FIG. 1, an elastic tube 17 is attached to the tube attaching / detaching portion 15. The elastic tube 17 is made of a durable and flexible material, and is preferably made of, for example, silicon rubber or the like, and its length is preferably about 220 mm. Here, the tube attaching / detaching portion 15 is a tubular portion as shown in FIG. 3, and is attached by forcibly inserting it into the elastic tube 17 as shown in FIG.
It is designed to be removed by forcibly pulling it out.

At the tip end of the elastic tube 17,
8 are formed. The mouthpiece 18 is formed by inserting a mouthpiece member 19 from an opening on the distal end side of the elastic tube 17. The mouthpiece member 19 is attached to the mouthpiece 18 so that when the caregiver holds the mouthpiece 18, the mouthpiece member 19 reaches deeper than the position where the teeth touch. To do so, the entire length of the mouthpiece member 19 is formed sufficiently long. Therefore, the mouth member 19 is
An expanded portion 19a having an overall length of, for example, about 30 mm and located on the distal end side of the tube and exposed to the outside, and a reduced-diameter portion 19b provided on the inner side thereof and inserted into the elastic tube 17 are provided. Have.

As a result, the location of the mouthpiece 18 is held in a mold by the mouthpiece member 19 and is less likely to be deformed. That is, since the mouth member 19 has a length reaching the back side from the position where the caregiver's teeth touch, the mouth 18 is effectively prevented from being deformed by engaging the caregiver's teeth. In addition, since the mouthpiece member 19 is formed to be long, the diameter-reduced portion 19b on the back side is formed so as to gradually become thinner toward the end in order to assist the insertion of the mouthpiece 18 from the front end opening. I have.

A plurality of non-slip protruding portions 12f extending in the vertical direction are formed on the outer periphery of the lower end portion, which is the portion having the largest diameter, of the lid portion 12.

The present embodiment is configured as described above. Next, its operation will be described while explaining how to use it. A caregiver (not shown) such as a mother holds an infant or the like with one hand in an upright posture. Next, the mouthpiece 18 of the elastic tube 17 is attached to the mouth, and FIG.
Of the nasal aspirator 10 of FIG. At this time, the accommodation container 11 has an appropriate size that fits in the palm, and in this state, the suction head 14 above the lid 12
The suction port 14a at the tip of is slightly inserted into the nostril of an infant or the like.

At this time, the container 1 having a relatively large outer diameter is used.
1, a reduced diameter portion 13 of the lid portion 12 is provided for a distance of L1 in FIG. 3, and a distance to the tip of the suction head 14 by the neck portion 14c and the bulging portion 14b. Therefore, the suction port 14a can be arranged in the nostril at an angle at which an appropriate suction operation can be performed without the large outside diameter of the housing container 11 interfering with the slightly protruding lips of the infant.

Then, the caregiver performs suction through the suction port 18 of the elastic tube 17. At this time, the container 11
Is firmly supported by the caregiver's hands, so it does not swing as before,
The suction head is not pulled and does not shift.

When the nasal discharge sucked from the nostrils of the infant has low viscosity, it passes through the relatively long communication path 16 via the suction head 14 and is guided into the container 11. At this time, as described above, since the communication passage 16 has a long creepage distance to the inner opening of the tube attaching / detaching portion 15,
Based on the suction force, nasal discharge is effectively prevented from reaching the inner opening of the tube attaching / detaching portion 15. In this way, the nasal discharge is reliably stored in the storage container 11, so that accidental intrusion into the mouth of a caregiver such as a mother can be effectively prevented and sanitary.

Further, in the above suction operation, the path through which the suction force as a negative pressure is transmitted is short because the suction head 14 is not separated from the storage container 11 by a tube or the like. Therefore, a large pressure loss is applied to the suction force as in the past,
It is not damaged more than necessary. On the other hand, since the opening of the elastic tube 17 having a small cross-sectional diameter communicates with the container 11 having a large inner diameter via the tube attaching / detaching portion 15, a relatively large negative pressure based on the suction of the caregiver is thereby reduced.
Appropriately reduced. This effectively prevents an excessive negative pressure from being suddenly applied to the nostrils of the infant or the like from the suction port 14a of the suction head 14.

In the case of nasal secretion having a large viscosity, the nasal secretion present on the back side is drawn into the vicinity of the nostril without being sucked up to the housing container 11 by the above-mentioned suction operation. Can be removed.

Further, in addition to the above, in the conventional suction device 1 shown in FIG. 6, the two tubes 3 and 4 extend above the container 6 with the container 6 interposed therebetween. As a whole, its center of gravity was higher. For this reason, when the aspirator 1 is washed and left to dry by drying, the portion of the container 6 falls down, which makes storage difficult. However, the nasal aspirator 10 of the present embodiment has a drawback. Then, it differs in the following points. That is, according to this embodiment, there is only one relatively heavy elastic tube 17,
Moreover, it extends laterally from the side surface of the lid 12. For this reason,
After the nasal aspirator 10 has been washed without any extreme movement of the center of gravity, the bottom of the container 11 can be placed downside down, which is convenient for organizing.

The present invention is not limited to the above embodiment.
If the suction head has a bulge larger than the nostril,
Any shape may be used. Further, the suction head portion and the reduced diameter portion may be integrated without providing a neck portion. Alternatively, the reduced diameter portion may be formed on the container side, and only the suction head portion may be attached and detached to open the container side. Furthermore, the shape of the storage container 11 may be modified so that the caregiver is particularly easy to use with one hand.

[0036]

As described above, according to the present invention, it is possible to stably perform a suction operation in which a suction head is applied to a nostril of an infant or the like, and to safely use the suction work without imposing a burden on an assistant. A nasal aspirator capable of being provided can be provided.
