Abstract
The present invention relates to a drip tube for an infusion device, and in particular, to a drip tube for an infusion device capable of preventing accidents such as injection of air into a patient when infusion ends or when an infusion discharge in an infusion bag has occurred.
Description
Technical Field
The present invention claims the benefit of priority based on korean patent application No. 10-2021-0110275, which was filed on the year 2021, month 09, and date 0110275, and korean patent application No. 10-2022-0108557, which was filed on the year 2022, month 08, and 29, all of which are disclosed in the documents of the corresponding korean patent applications are incorporated as part of the present specification.
The present invention relates to a drip tube for an infusion device, and in particular, to a drip tube for an infusion device capable of preventing accidents such as injection of air into a patient when infusion ends or when an infusion discharge in an infusion bag has occurred.
Background
Infusion sets may be used for patients who have problems in the digestive system or who are unable to take drugs or food due to loss of consciousness or the like. In particular, the artificial solution may be injected intravenously or subcutaneously, rather than orally, and may be injected into the patient over a period of minutes or even hours.
At this time, when the infusion is empty or a problem occurs in the infusion flow path, air may be injected into the patient instead of the infusion. If air flows into the vein, the air can block the blood vessel, thereby causing dysfunction and possibly even death in severe cases.
For example, medical staff is very concerned about medical accidents caused by the fact that the empty infusion in an infusion bottle (bag) is not found in time, and in fact, the related infusion accidents frequently occur. Particularly, in the night or civil and military emergency measures, the condition that whether the transfusion bottle (bag) and the transfusion tube are exhausted or not is frequently and orderly confirmed is unavoidable.
Due to fear of this, the patient and guardian always closely observe the state of the infusion in the infusion bottle (bag) and the infusion tube, and often seek assistance to medical staff such as nurses at a point in time when the infusion bottle (bag) is empty.
Accordingly, there is a need for a technique for preventing air from entering into a blood vessel of a patient when infusion is ended or when there is a problem with an infusion bag and an infusion flow path.

Fig. 8 is a conceptual diagram illustrating a method of manufacturing the regulator 110 provided in the drip chamber 100 for an infusion device according to the present invention.
Hereinafter, the drip tube 100 for an infusion device according to the present invention will be described in detail with reference to fig. 1 to 8.
The drip tube 100 for an infusion device according to the present invention prevents air from being injected into a patient when the infusion is completely consumed in an infusion container (an infusion bottle, an infusion bag, etc.) in which the infusion is stored, and thus can prevent accidents such as blood reflux of the patient. Specifically, the flow path is blocked when the transfusion in the transfusion tube 100 for the transfusion device connected to the lower end portion of the transfusion container is exhausted, so that the air injection into the patient can be prevented.
The drip tube 100 for an infusion set of the present invention may be provided in a flow path connecting an infusion container and a patient. Specifically, the infusion device is arranged at the lower side of the infusion container, and the infusion is injected into a patient by gravity through the infusion tube.
As shown in fig. 1 and 2, a drip tube 100 for an infusion device of the present invention may include:
an introduction needle 130 extending in the up-down direction, the upper end portion of which is inserted into an infusion container in which infusion is stored;
a transparent container 120 extending in the up-down direction and receiving the infusion solution through the introduction needle 130; and
the regulator 110 is located inside the transparent container 120 and has a lower specific gravity than the infusion solution.
The introduction needle 130 may be provided in a rod shape formed with a sharp upper end and extending in the up-down direction. The inside of the introduction needle 130 is formed with a flow path extending in the up-down direction so that the infusion of the infusion container can be injected from the upper end portion of the introduction needle 130 and then discharged from the lower end portion of the introduction needle 130 through the flow path, thereby allowing the infusion of the infusion container to be injected into the drip tube.
As shown in fig. 2 and 3, the transparent container 120 may include: a transparent body part 121 extending in the up-down direction, having an infusion drip space 121a for dripping the infusion, and having an open upper end; a stopper 122 coupled to an upper end of the transparent body 121, and to which a lower end of the introduction needle 130 is coupled; a discharge port 123 provided at a lower end portion of the transparent body 121 and discharging the infusion solution inside the transparent body 121.
The inside of the transparent body part 121 may be formed as a hollow as the infusion drip space 121 a. For example, the transparent body portion 121 may be provided in a cylindrical shape extending in the up-down direction. More specifically, the transparent body portion 121 may be provided in a tapered shape with a diameter gradually decreasing toward the lower side. The transparent body portion 121 is provided in a shape with an upper end portion opened, and the stopper portion 122 is coupled to the upper end portion, so that the infusion drip space 121a can be formed as a closed space.
The plug 122 may have a drip hole 122a formed therethrough in the up-down direction. The lower end of the introduction needle 130 is inserted into the upper inlet of the drip hole 122a, and can be coupled to the plug 122. The lower inlet of the drip hole 122a protrudes downward from the bottom surface of the stopper 122, so that the infusion solution injected into the drip tube through the introduction needle 130 can be guided to drop in the form of droplets.
The transparent body portion 121 may be made of a rigid material that is transparent to visible light. The transparent body part 121 is made of a transparent material so that the drip state of the infusion can be visually observed at the outside of the transparent body part 121.
As shown in fig. 2 to 4, an attaching groove 124 having the same shape as the bottom surface of the regulator 110 may be formed at the inner bottom surface of the infusion drop space 121a of the transparent body part 121, and the upper inlet of the discharge port 123 may be located at the center of the attaching groove 124.
As shown in fig. 2 to 4, the regulating member 110 may move up and down along with the change in height of the liquid level 13 formed by the infusion in the infusion drip space 121a, and when the infusion is completely discharged in the infusion drip space 121a, the bottom surface of the regulating member 110 adheres to the adhesion groove 124, blocking the upper side inlet of the discharge port 123. The density of the regulating member 110 is set to be smaller than that of the infusion solution so that the regulating member 110 can be positioned at the liquid level 13 of the infusion solution formed in the infusion drip space 121 a. Therefore, when the infusion drip space 121a is filled with sufficient infusion, the regulator 110 is spaced from the upper inlet of the discharge port 123 and does not block the flow of the fluid discharged from the discharge port 123, but when the infusion is completely discharged in the infusion drip space 121a, the regulator 110 falls down and blocks the discharge port 123.
The adjusting member 110 may include: a lower end member 112 having a bottom surface attached to the attaching groove 124; an upper end member 111 coupled to an upper end portion of the lower end member 112.
As an embodiment, as shown in fig. 5a, the upper end member 111 may be formed in a hemispherical shape with a bottom surface constituting a plane, and the lower end member 112 may be formed in a hemispherical shape with a top surface constituting a plane.
As another embodiment, as shown in fig. 5b, the upper end member 111 may be formed in a hemispherical shape having a bottom surface constituting a plane, and the lower end member 112 may be formed in a conical shape having a top surface constituting a plane and a vertex facing downward.
As in the above embodiment, the lower end member 112 may be formed in such a shape that a contact surface with the inner peripheral surface of the attachment groove 124 can be formed large. The large contact surface of the lower end member 112 with the attaching groove 124 can enable the regulator 110 to reliably block the air discharged through the discharge port 123.
The lower member 112 may be a polymer formed by connecting a silicone to which an organic group is bonded through a siloxane bond. Since the density of the regulating member 110 needs to be formed to be smaller than that of the infusion solution, the overall load of the regulating member 110 may be limited. In the drip tube 100 for an infusion device of the present invention, the lower end member 112 is provided of the material excellent in viscoelasticity so that even a small load can be sufficiently attached to the attachment groove 124, whereby the air flowing in through the discharge port 123 can be blocked.
The lower end of the lower end member 112 may have a downwardly extending tail member (not shown). The tail member may be provided in a cylindrical shape, and an outer diameter of the tail member may be formed smaller than an inner diameter of the discharge port 123. For example, the outer diameter of the tail member may be formed to be 50% or less of the inner diameter of the discharge port 123. The lower end of the tail member is inserted into the discharge port 123, and the length of the tail member may be formed longer than the length of the infusion drip space 121a in the up-down direction. The lower end portion of the lower end member 112 is provided with a tail member, so that the lower end member 112 can be prevented from facing upward.
As described above, the upper end member 111 is made of a material having a higher hardness than the lower end member 112, and the upper surface of the lower end member 112 is formed with the coupling protrusion 112a for inserting the upper end member 111, and the bottom surface of the upper end member 111 may be formed with the receiving groove 111a into which the coupling protrusion 112a is inserted. The upper end member 111 is made of a rigid material and the lower end member 112 is made of a flexible material, thereby making assembly for the coupling between the upper end member 111 and the lower end member 112 easier.
The depth of the receiving groove 111a may be formed deeper than the height of the coupling protrusion 112a, so that the inside of the upper end member 111 may be formed to be hollow in a state where the upper end member 111 is coupled with the lower end member 112. The density of the adjusting member 110 may be adjusted by the size of the hollow.
As shown in fig. 6 and 7, the coupling protrusion 112a is provided in a cylindrical shape, a coupling groove 112b may be formed in a circumferential direction at a lower side of an outer circumferential surface of the coupling protrusion 112a, and an insertion protrusion 111b capable of being inserted into the coupling groove 112b may be formed at a lower side of an inner circumferential surface of the receiving groove 111a. For example, the coupling groove 112b and the insertion protrusion 111b may be provided in a ring shape, and an inner diameter of the ring formed by the insertion protrusion 111b may be formed smaller than an upper outer diameter of the coupling protrusion 112a, and a depth of the coupling groove 112b may be greater than a difference between the upper outer diameter of the coupling protrusion 112a and the inner diameter of the ring formed by the insertion protrusion 111b.
As shown in fig. 8, the method of manufacturing the regulator 110 provided in the drip chamber 100 for an infusion device of the present invention may include:
a needle insertion step of inserting the suction needle 11 so as to penetrate the lower end member 112 from the lower side of the lower end member 112 in the up-down direction;
a bonding step of bonding the upper end member 111 and the lower end member 112 such that a bottom surface of the upper end member 111 faces an upper surface of the lower end member 112;
a discharging step of discharging the air formed in the hollow through the suction needle 11;
a final step of removing the suction needle 11 from the lower end member 112.
An upper end portion of the coupling protrusion 112a may form a hemispherical recess 112c, and an upper end portion of the suction needle 11 may protrude from a center of the recess 112c in the needle insertion step. The recess 112c may be provided in a spherical shape.
In the needle insertion step, a flow path is formed inside the suction needle 11 so that air existing in the hollow inside the regulator 110 formed by combining the upper end member 111 and the lower end member 112 can be discharged to the outside of the regulator.
In the coupling step, the recess 112c formed in the coupling protrusion 112a can make the coupling protrusion 112a more easily contracted, so that insertion of the coupling protrusion 112a into the receiving groove 111a becomes easier.
Further, the recess 112c makes the hollow inside the adjuster 110 formed by combining the upper end member 111 and the lower end member 112 larger in size, thereby making it easier to achieve density adjustment of the adjuster 110.
During the coupling of the upper end member 111 and the lower end member 112, the air of the accommodating groove 111a is compressed, and the hollow medium pressure inside the regulator 110 formed by the coupling of the upper end member 111 and the lower end member 112 rises. The high pressure air may separate the upper end member 111 from the lower end member 112. To prevent this, the hollow space inside the regulator 110, which may be formed by combining the upper end member 111 with the lower end member 112, may be formed to be capable of having a lower pressure than the atmospheric pressure through the discharging step.
Although embodiments according to the present invention have been described above, this is only illustrative, and it is to be understood that various modifications and equivalent scope of embodiments can be made according to these embodiments by those skilled in the art. Accordingly, the true technical scope of the present invention should be defined by the appended claims.
