BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a chemical-solution injecting apparatus including a plurality of balloon infusers,

The present application relates to a chemical liquid injecting apparatus including a plurality of balloon infusers.

A balloon infuser, also referred to as a balloon infusion pump or a portable infusion pump (PIP), is used to continuously infuse a drug at a constant rate, such as an anticancer drug, It is a disposable drug injection device used for. It is common that a separate speed adjusting mechanism is used in combination.

Balloon infusers are safe and hygienic from external factors, are easy to carry, do not need separate power supply, and do not have a designation in everyday life, so patients who need continuous medication can go to hospital without hospitalization Research and demand are on the rise.

In the case of the balloon infuser, the drug is stored in the expanding member, and as the expanding member is reduced, the drug is discharged to the outside as the elasticity changes. However, the elasticity changes according to the size of the expanding member, and when the drug is fully stored, the drug injection rate is fast, but when the drug is only stored in a small amount, the drug injection rate is slow.

To solve these drawbacks, Korean Patent Registration No. 10-0893780 discloses a technique of arranging a plurality of balloon infusers in parallel in order to minimize the change of the elastic force according to the size of the expansion member. However, since the drug discharged from each balloon infuser is directly mixed at the outlet side in such an injection apparatus, crystallization phenomenon easily occurs when the different drugs are mixed and injected. It is important to minimize the crystallization phenomenon because it is fatal when the crystallized drug is injected into the human body.

In modern medicine, cocktail therapy, which is a mixture of different drugs, is used not only for AIDS treatment but also for nutritional therapy, and there is a growing need for an injection device that does not cause crystallization even with different drugs It is true.

One. Balloon Of the infuser  Outline description

Referring to FIG. 1, a chemical liquid injecting apparatus according to an embodiment of the present application includes a plurality of balloon infusers 100 (100a, 100b).

The balloon infuser may be any conventional balloon infuser. Shown in Figures 2 and 3 is an example of a balloon infuser.

The lower cover 122 is located on the lower side.

The upper connector 113 and the lower connector 117 can use the same member, and the upper connector holder 112 and the lower connector holder 118 can use the same member. This makes it easier to manufacture and lower the manufacturing cost.

The upper cover 121 and the lower cover 122 form the appearance of the balloon infuser according to the present invention. A graduation line 121a is printed on the upper cover 121. The graduation line 111a of the ascending and descending section 111 ascends and descends according to the ascending and descending of the ascending and descending section 111, Contents can be guided.

The upper connector holder 112 and the upper connector 113 are coupled to the ascending and descending portion 111. It is firmly fixed by snap coupling without the need for an adhesive or the like.

Similarly, the lower connector holder 118 and the lower connector 117 are fixed to each other by the snap connection without the adhesive in the lower opening 123 of the lower cover 122 as well.

An inner shaft 114, an outer shaft 116 and an expansion member 115 are located between the upper connector 113 and the lower connector 117.

The inner shaft 114 is fixed to the lifting and lowering portion 111 by the upper connector 113.

The outer shaft 116 is fixed to the lower cover 122 by a lower connector 171.

As the contents are injected into the balloon infuser, the expansion member 115 expands, and the inner shaft 114 and the ascending / descending portion 111 coupled thereto rise. Conversely, as the contents flow out, the expansion member 115 shrinks, and the inner shaft 114 and the ascending / descending portion 111 coupled thereto descend.

At both ends in the longitudinal direction of the inner shaft 114, stopping hooks 114a and 114b for installing the expansion member 115 may be formed. The amount of the chemical solution stored in the expansion member 115 can be accurately determined by installing the expansion member 115 at the same position of the inner shaft 114. [

2. Chemical solution  Description of injection device

Referring to Figs. 1, 3 and 4, a chemical liquid injecting apparatus 1000 according to an embodiment of the present application will be described in more detail.

1, a chemical liquid injecting apparatus 1000 according to an embodiment of the present invention includes a plurality of balloon infusers 100 (100a, 100b), a plurality of discharge lines 200 (200a, 200b), and a single mixing line 300 ).

Since the configuration of the balloon infuser 100 has been described above, the description of the overlapping portions will be omitted.

The upper cover 121 and the lower cover 122 form an outer appearance. Hereinafter, the upper cover 121 and the lower cover 122 are collectively referred to as a case 120. In addition, the internal structure accommodated in the case 120 is defined as a chemical liquid storage unit 110. [

The chemical liquid injector 1000 according to the embodiment of the present application includes a plurality of balloon infusers 100. 1 shows two balloon infusers, but it is also possible to have three or more ballpoint infusers.

The balloon infusers 100 (100a, 100b) are preferably arranged in a row as shown in FIG. Therefore, only by viewing the plurality of balloon infusers 100 (100a, 100b) from one side, the scale guide line 111a of the ascending and descending portion 111 is lifted and lowered in accordance with the ascending and descending of the ascending and descending portion 111 of each balloon infuser And refers to the scale line 121a of the case 120. [ That is, the amount of the chemical liquid remaining in each balloon infuser can be easily known.

The chemical liquid injector 1000 according to the embodiment of the present application is provided such that one case 120 accommodates each of the chemical liquid storage units 110 of the plurality of balloon infusers 100a and 100b. The case 120 is formed by an injection method. Since the case 120 receives only one case 120 to accommodate each of the chemical solution storage units 110, the convenience of manufacture is improved.

In addition, one handle 130 is formed on the upper portion of the case 120. One end of the chemical liquid injector 1000 is mounted and fixed to the chemical liquid injecting object, and the balloon infuser 100 (100a, 100b) must also move for the chemical liquid injecting object to move. The handle 130 is formed on the case 120 so that the balloon infuser 100 (100a, 100b) can be easily moved while holding the handle 130. [

The balloon infusor 100 (100a, 100b) is connected to a discharge line 200 (200a, 200b) which is a passage through which the chemical solution stored in the expansion member 115 is discharged. Since one discharge line is connected to one balloon infuser, the number of discharge lines is equal to the number of balloon infusers.

The important point here is that the respective discharge lines 200a and 200b are provided separately from each other so that the chemical solution stored in each balloon infuser is discharged without mixing.

The chemical liquid injection ports 201a and 201b are formed in the discharge lines 200a and 200b, respectively. It is possible to inject the chemical solution into the expansion member 115 through the chemical solution injection ports 201a and 201b.

Further, a discharge rate control unit (not shown) may further be formed in the discharge lines 200a and 200b. Therefore, when the different chemical fluids are stored in the respective balloon infusers 100 (100a, 100b), it is possible to separately control the discharge speed of the respective chemical fluids.

The discharge rate control unit (not shown) may adjust the discharge rate by controlling the intensity of the discharge lines 200a and 200b by the movement, such as the discharge rate control unit installed in the liquid line of the infusion set. have.

It is also possible to make the materials of the expansion members included in the respective balloon infusers to be different from each other, and to take different velocities from the respective balloon infusers. When the materials are taken differently, the elastic restoring forces of the expanding members will be different from each other, and therefore, this principle is used.

One end of the plurality of discharge lines (200a, 200b) is connected to one mixing line (300). That is, the plurality of discharge lines 200a and 200b are combined into one mixing line 300, and the chemical liquid discharged through each of them is mixed in the mixing line 300. [

Here, it is preferable that the inner diameter of the mixing line 300 is larger than the inner diameter of the discharge lines 200a and 200b. It is most important that the chemical liquid injector 1000 inject the chemical liquid at a desired speed.

Since the mixing line 300 is a passage through which the chemical liquids passing through the discharge lines 200a and 200b are all injected, when the inner diameter is smaller than or equal to the inner diameter of the discharge lines 200a and 200b, . Therefore, it is preferable that the inner diameter of the mixing line 300 is larger than that of the discharge lines 200a and 200b in order to be injected into the chemical liquid injecting object through the mixing line 300 at the speed of being discharged to the discharge lines 200a and 200b .

배인 것이 바람직하다. 이는 n개의 배출 라인을 통과하는 약액의 총량과 1개의 혼합 라인을 통과하는 약액의 양이 일치하는 수치이다. 따라서, 실제로 팽창 부재(115)를 통하여 배출되는 속도만큼 약액 주입 대상에 약액을 주입할 수 있다.More preferably, the inner diameter of the mixing line 300 is set such that the number of the discharge lines 200a, 200b is n, and the inner diameter of the discharge lines 200a,

It is preferable that it is double. This is a numerical value in which the total amount of the chemical liquid passing through the n discharge lines and the amount of the chemical liquid passing through one mixing line coincide with each other. Therefore, the chemical liquid can be injected into the chemical liquid injecting object at the speed at which it is actually discharged through the expansion member 115.

Referring to FIG. 1, the mixing line 300 includes a first mixing line 310, a filter 320, and a second mixing line 330.

The filter 320 is a part for removing foreign substances contained in the chemical liquid, and removes a part where crystallization occurs and precipitates.

The first mixing line 310 is connected to the upper side of the filter 320 and has one end connected to the plurality of discharge lines 200a and 200b.

The second mixing line 330 is connected to the lower side of the filter 320 and is connected to an injection catheter 400 which is inserted and fixed at one end to the chemical liquid injecting object.

Here, the length of the first mixing line 310 is preferably 3 cm to 5 cm, and the length of the second mixing line 330 is preferably 15 cm to 17 cm.

As described above, when different drugs are stored in the balloon infuser, a crystallization phenomenon occurs when the chemical liquid discharged through the discharge line is mixed in the mixing line 300. The frequency of occurrence of the crystallization phenomenon is proportional to the mixing time of the different chemical liquids. Therefore, it is important to minimize the length of the mixing line 300.

Specifically, the length of the mixing line 300 is preferably 18 cm to 22 cm.

An injection catheter 400 is connected to the end of the mixing line 300. One end of the injection catheter 400 is positioned inside the blood vessel and injects the drug solution delivered through the mixing line 300 into the blood vessel.

Since the infusion catheter 400 has to be inserted and inserted into the blood vessel, the mixing line 300 connected to the infusion catheter 400 is also required to be fixed. As shown in FIG. 6, the mixing line 300 is fixed by an adhesive tape or the like, and the important thing is not fixed in a straight line but fixed in a curved shape to the chemical liquid injection object.

The length of the mixing line 300 itself may be shorter but the movement of the mixing line 300 is still transmitted to the injection catheter 400 so that the movement of the injection catheter 400 causes the blood vessel A phenomenon of puncturing may occur.

Therefore, it is preferable to have a length that can be attached and fixed to the hand of the chemical liquid injection object in a curved shape.

A length of 18 cm to 22 cm of the mixing line 300 is a length design considering the aforementioned items and an average hand size. When the length of the mixing line 300 is shorter than 18 cm, even if it is attached in a curved shape, Of the total length. Therefore, there is a high possibility that the movement of the drug solution injection target is uniformly transmitted to the mixing line 300, which is transmitted to the injection catheter 400, which causes the above-mentioned punching phenomenon.

Further, when the length of the mixing line 300 is longer than 22 cm, there occurs a phenomenon that solids and the like are precipitated while different drugs are mixed with each other. This causes line clogging and is fatal when injected into blood vessels.

The length of the mixing line 300 is set to be 18 cm to 22 cm, which is a length that has a sufficient fixing force attached to the chemical liquid injecting object in accordance with the average hand size of a person, but has a minimized crystallization phenomenon.

Therefore, stable chemical liquid injection can be performed, and crystallization phenomenon can be minimized.

The discharge lines 200a and 200b and the mixing line 300 are connected by a connecting part 220. The connection portion 220 is a portion where a plurality of discharge lines 200a and 200b are gathered. That is, it serves as a hub for connecting the plurality of discharge lines 200a and 200b to one mixing line 300. [

Since the rear end of the connection part 220 is connected to the discharge lines 200a and 200b, the first connection passage 221 positioned at the rear end is connected to the inner diameter of the discharge line 200a and 200b, And the front end (the lower portion of the connecting portion) is connected to the mixing line 300, the second connecting passage 222 located at the front end has an inner diameter into which the mixing line 300 can be inserted.

It will be apparent to those skilled in the art that various modifications and variations may be made in the present invention without departing from the spirit and scope of the present invention as defined by the appended claims. It will be appreciated that embodiments are possible. Accordingly, the scope of protection of the present application should be determined by the claims.
