Abstract

PROBLEM TO BE SOLVED: To provide an extracorporeal puncture-in type drain system wherein scars after drain extraction are hard to be left, and which does not impart a large load on a patient when indwelling drains again.SOLUTION: In an extracorporeal puncture-in type drain system, a plurality of three-way cocks mounted with indwelling needles through extension tubes are connected, and a closed type continuous aspirator is connected to the three-way cook positioned in the most downstream position through a drainage tube.

Description

  The present invention relates to an extracorporeal insertion type drain system in which scars after removal are less likely to remain and the burden on a patient at the time of repositioning is small.

In general, when there is exudate or bleeding from the wound surface in a surgical wound and there is a possibility that it will be collected after the operation, a drain for drainage is inserted and placed in the wound subcutaneous (muscle layer) at the time of suturing ( For example, refer nonpatent literature 1).
However, since the drain inserted and placed in the wound subcutaneous (muscle layer) has a large outer diameter of 10 to 15 Fr (about 3.3 to 5 mm), there is a problem that the scar after the drain is removed remains large. was there.
Further, in the conventional method as described above, when the drain becomes necessary again after being removed, it must be re-opened and inserted and placed, so that the burden on the patient is large. It was.

  The present invention has been made in view of the above-described conventional problems and circumstances, and provides an extracorporeal insertion type drain system in which scars are hardly left after the drain is removed, and the burden on the patient at the time of repositioning is small. It is an issue.

  As a result of repeated studies to solve the above problems, the present inventor used an indwelling needle having a smaller outer diameter as compared to a conventionally used drain as the drain, and the indwelling needle and the three-way stopcock via a tube. The present invention has been completed by finding that extremely good results can be obtained by connecting a closed continuous suction device with a closed type.

  That is, the present invention is to connect a plurality of three-way stopcocks equipped with indwelling needles via extension tubes and connect a closed continuous suction device to the most downstream three-way stopcocks via drainage tubes. The above-described problems are solved by the extracorporeal insertion type drain system.

  Since the present invention uses an indwelling needle having a smaller outer diameter as compared to a conventionally used drain, the scar is hardly noticeable after the indwelling needle is removed, and is particularly effective for use in the field of cosmetic surgery. It is.

  In addition, since the present thin indwelling needle is inserted from the skin side and used, the present invention can be easily and reliably inserted and placed in a place where the exudate is easily stored, and there is a need for a drain again after removal. Even if it occurs, it can be percutaneously inserted and placed without opening, so the physical and mental pain and burden on the patient can be greatly reduced, especially for outpatients. Thus, continuous suction can be performed easily and effectively.

  Furthermore, since the closed suction device is used in the present invention, unlike the open type, contact with the outside world is blocked, so that retrograde infection can be prevented.

BRIEF DESCRIPTION OF THE DRAWINGS Schematic structure explanatory drawing of this invention drain system.

  Embodiments of the present invention will be described below with reference to the drawings.

  In FIG. 1, 10a to 10c are three-way stopcocks, each of which is connected in a straight line with three sides opened. One indwelling needle 30a, 30b is attached to and communicated with the three-way stopcocks 10a, 10b via extension tubes 20a, 20b, respectively, and the extension tubes 20c, 20d are connected to the three-way stopcock 10c at the most upstream position. A total of two indwelling needles 30c and 30d are attached and communicated via the.

Generally, the indwelling needle has a smaller diameter than that of a conventionally used drain, but the indwelling needles 30a to 30d used in the present invention have an outer diameter of 2 mm or less, particularly a 16 to 18G surflow needle, which reduces scarring and drainage efficiency. In this respect, better results are obtained.
As the extension tubes 20a to 20d, extension tubes that are usually used for medical purposes (for example, an outer diameter of 3.8 mm, an inner diameter of 2.5 mm, and a length of 50 cm) are preferably used.

Further, a closed continuous suction device 50 is connected to the most downstream three-way cock 10a through a drain tube 40. Here, as the closed continuous suction device 50, for example, “J-VAC drain” (manufactured by Johnson & Johnson) is preferably used. Incidentally, the suction pressure of the suction device 50 is usually preferably 40 to 60 mmHg.
As the drainage tube 40, for example, a 15 Fr tube is preferably used as in the case of the conventional drain.

Next, a method of using the extracorporeal insertion type drain system of the present invention will be described.
First, the indwelling needles 30a to 30d are inserted into portions where the exudate is easily stored percutaneously. Next, the connection region between the indwelling needles 30a to 30d and the extension tubes 20a to 20d exposed to the outside is appropriately fixed with an adhesive tape or the like. Next, when the closed continuous aspirator 50 is operated, the exudates are respectively transferred from the indwelling needles 30a to 30d to the extension tubes 20a to 20d, and then from the three-way stopcocks 10a to 10c through the drain tube 40 to the closed continuous aspirator 50. Sucked.

  Incidentally, although the indwelling needles 30a to 30d have a smaller diameter than the conventionally used drain, a plurality of the indwelling needles 30a to 30d are used for suction, so that the same suction amount as in the conventional case is secured.

10a to 10c: Three-way stopcocks 20a to 20d: Extension tubes 30a to 30d: Indwelling needle 40: Drainage tube 50: Closed continuous suction device
