Description

Technical Field

[0001] The present invention relates to a holder for an infusion tube for infusion, in a medical infusion set in which an infusion tube connected to a patient is connected to a plurality of infusion pumps or syringe pumps via a multi-way three-way stopcock and a plurality of infusion tubes connected thereto. Between the multi-way three-way stopcock and the infusion pump or syringe pump, a plurality of infusion tubes are arranged in parallel and held by a support around the bed like a bedrail without entanglement.

Background Art

[0002] Conventionally, in a medical infusion system, a plurality of infusion tubes each connected to a plurality of infusion pumps or syringe pumps for each drug are connected to an infusion tube connected to a patient via a multi-way three-way stopcock. In such an infusion system, since a plurality of infusion tubes are intricately entangled, it becomes difficult to identify and confirm the drugs passing through the infusion tubes, which hinders the quick and accurate replacement of the drug-specific infusion tubes. To solve this problem, a fixing belt for an infusion tube has been proposed in Patent Document 1, in which a plurality of fasteners are provided at regular intervals on a belt-like body, and the infusion tubes are fixed in parallel by passing the infusion tubes through each passage formed by fastening these fasteners. In addition, when a plurality of intravenous drip injections of different drugs are performed on a single patient, a holder for an infusion tube that prevents entanglement of the infusion tube has been proposed in Patent Document 2 so as not to interfere with the patient's movement or the replacement operation of the infusion device. This holder for an infusion tube is attached to an infusion stand via a fixing member, is located at a position away from the patient, and does not address the congestion of the infusion tubes near the patient.

Summary of the Invention

Problems to be Solved by the Invention

[0004] An object of the present invention is to provide a simple and easy-to-handle holder that can hold a plurality of infusion tubes in parallel without entanglement between a plurality of infusion pumps or syringe pumps and a multi-way stopcock and hold them on a support around the bed.

Means for Solving the Problems

[0005] In the following description, reference is made to the reference numerals in the accompanying drawings, but the present invention is not limited thereto. The holder 1 of the present invention for solving the above problems comprises a base body 2 made of a foamed plastic molded body having substantially rectangular parallelepiped side surfaces in the front-rear, left-right, and up-down directions, a reinforcing member 3 made of an elastic synthetic resin fitted and fixed in the base body 2, and a fixing member 4 for holding the base body 2 on a support 106 around the bed such as a bed rail. The base body 2 includes a plurality of slits 21 arranged in parallel at a predetermined mutual interval in the left-right direction and extending to a terminal position exceeding half of the vertical height from the upper surface to the lower surface, a plurality of guide grooves 22 having a substantially V-shaped cross section that open upward along the upper ends of the slits 21 and extend in the front-rear direction, a plurality of clamping portions 23 defined by the slits 21 on the left and right and connected to each other by a continuous portion 24 at the lower portion, and a substantially upward U-shaped notch 25 for fitting the reinforcing member 3. The notch 25 includes a horizontal cut portion 25a that penetrates the continuous portion 24 through the front and rear surfaces and extends horizontally in parallel with the lower surface, and vertical cut portions 25b that bend upward at right angles from both ends of the horizontal cut 25a and extend into the clamping portions 23 located at both left and right ends.

Embodiments for Carrying Out the Invention

[0008] Embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a general drip set to which a holder 1 for a drip tube according to the present invention is applied. An infusion tube 103 extends from a plurality of syringe pumps 101 or infusion pumps 102 and is connected to each stopcock of a multi-way stopcock 104. A drip tube 105 extends from the multi-way stopcock 104 to the patient side. The holder 1 is provided at a position close to the multi-way stopcock 104 in the middle of the extension of the infusion tube 103 and is fixed on a support 106 near the patient's bed such as a bed rail.

[0009] As shown in FIG. 2, the holder 1 includes a substantially rectangular parallelepiped-shaped base body 2 having front, rear, left, right, upper, and lower side surfaces, a reinforcing member 3 made of an elastic synthetic resin fitted and fixed in the base body 2, and a fixing member 4 for holding the base body 2 on the support 106.

[0010] The base body 2 is a foamed plastic molded body, and includes a plurality of slits 21 for sandwiching the infusion tube 103, a plurality of guide grooves 22 for guiding the insertion of the infusion tube 103 into the slits 21, a plurality of clamping portions 23 for elastically clamping the infusion tube 103 on both sides of the slits 21, and a notch 24 for fitting the reinforcing member 3.

[0011] The material of the base body 2 can be selected from various ones. According to experiments, it is preferably composed of a closed-cell foam with a polyethylene resin as the base material. Considering the attachment to the bed fence, the size of the base body 2 is preferably about 50 mm in left-right width, 20 mm in front-back width, and 30 mm in height.

[0012] The slits 21 are arranged in parallel at a predetermined mutual interval in the left-right direction and extend to a terminal position exceeding 1 / 2 of the vertical height from the upper surface to the lower surface.

[0013] The guide grooves 22 open upward in a substantially V-shaped cross-section along the upper ends of the slits 21 and extend in the front-back direction.

[0014] The clamping portions 23 are defined left and right by the slits 22 and are connected to each other by a continuous portion 24 at the lower part.

[0015] The notch 25 includes a horizontal cut portion 25a that penetrates the continuous portion 24 through the front and rear surfaces and extends left and right parallel to the lower surface, and vertical cut portions 25b that bend upward at right angles from both ends of the horizontal cut portion 25a and extend into the clamping portions 23 at both left and right ends.

[0016] The reinforcing member 3 is made of a bent plate material of an elastic synthetic resin such as polyethylene, and includes a bottom plate portion 31 and a pair of standing plate portions 32 that bend and stand up from both left and right ends thereof. The bottom plate portion 31 is fitted into the horizontal cut portion 25a of the base body 2, and the standing plate portions 32 are fitted into the vertical cut portions 25b.

[0017] The pair of standing plate portions 32 are inclined inward in the natural state shown in Fig. 2, but are inserted into the slits 25 with the space between them widened against elasticity. After insertion, the standing plate portions 32 return to their original state, elastically tightening the space between the multiple clamping portions 23. The clamping force between adjacent clamping portions 23 is adjusted so that the infusion tube 101 can be held without causing a change in the flow rate of the medicinal liquid in the infusion tube 103 inserted into the slit 21.

[0018] The fixing member 4 is composed of first and second hook-and-loop fasteners 41 and 42. The first hook-and-loop fastener 41 is pre-adhered to the underside of the base 2 with its engaging portion 41a facing downward. The second hook-and-loop fastener has an engaging portion 42a on its upper surface that engages with the first hook-and-loop fastener 41, and an adhesive layer 42b formed on its lower surface. Before use, a release paper is attached to the adhesive layer 42b.

[0019] The fastening force between the hook-and-loop fasteners 41, 42 constituting the fixing member 4 is selected so that when the patient's body moves significantly, the base body 2 will detach from the support 106 before the intravenous needle comes out.

[0020] When using holder 1, adhesive layer 42b of hook-and-loop fastener 42 is exposed by peeling off the release paper or the like, and is adhered to support 106 close to the part of the patient's body to which drip tube 105 is connected, thereby fixing base 2. Next, transfusion tube 103 connected from syringe pump 101 or infusion pump 102 to multiple three-way stopcock 104 is inserted into slit 21 of base 2. At this time, the order of transfusion tube 103 in slit 21 is adjusted to match the order of the tubes in multiple three-way stopcock 104.

[0021] Even if the patient in the drip moves and the multi-way stopcock 104 moves, the infusion tube 103 is held by the holder 1 and its movement is restricted, so there is no risk of it falling from a support 106 such as a bedrail and causing a change in the flow rate. When the patient's movement is greater than a certain level, the surface fasteners 41a, 42a peel off to prevent the drip needle from coming out. Also, when the base 2 is composed of a closed-cell foam with a polyethylene resin as the base material, the infusion tube 103 is held with a predetermined frictional resistance between the slits 21. Therefore, when a tensile force greater than a certain level is applied to the infusion tube 103 due to the patient's movement, the infusion tube 103 moves axially between the slits 21 to prevent the drip needle from coming out.

[0022] For example, when replacing the infusion tube 103 of a specific syringe pump 101, by pulling the infusion tube 103 connected to the syringe pump 101 starting from the holder 1, the infusion tube 103 to be replaced can be easily found.

[0023] When transferring the patient from the bed to the stretcher, peel off the surface fastener 41, remove the holder 1 from the support 106, and move it together with the infusion tube 103. At this time, the transfer of the patient can be completed in a short time without causing entanglement of the infusion tube 103. Since no metal material is used for the holder 1, it can also be brought into inspection equipment such as an MRI.

[0024] Although not shown, if trumpet-shaped outward-opening openings are provided at the front and rear ends of the lower end of the slit 21 in the base 2, extreme bending that obstructs the infusion of the infusion tube 103 held in the slit 21 can be prevented.
