Description

Technical Field

[0001] The present application relates to a medical device, and in particular to an auxiliary fixation device for a limb drainage tube. Background Art

[0002] Patients with delirium or Alzheimer's disease are very likely to have drainage tubes pulled out after surgery. The root of the drainage tube first exposed from the drainage port needs to be observed frequently. This brings difficulties to the fixation of the drainage tube. Although there are various drainage tube fixing devices in the prior art, such as the "Use of Portable Drainage Tube Fixer" disclosed in CN115957422A, these fixing devices basically adopt the strategy of sticking the fixed base on the surface of the patient's body, and then clamping and fixing the drainage tube on the base. This fixing method cannot effectively fix the root of the drainage tube (i.e., the part just exposed from the drainage port), and the effect of preventing the drainage tube from being accidentally pulled out is relatively poor. Although CN210644807U sets a sticker around the drainage port and then fixes the drainage tube with a sticker, although this method fixes the root of the drainage tube, the large-area use of stickers can easily cause the covered skin to sweat and dissipate heat, which can easily cause the drainage port to ulcerate. Especially for drainage tubes on the upper or lower limbs, since they require activities and expose longer tubes, it is not conducive to the stability of the drainage tubes. Utility Model Content

[0003] In view of the above problems, the present application aims to propose an auxiliary fixation device for limb drainage tubes, which does not use adhesive, can protect the root of the drainage tube, and can effectively reduce the exposed length of the drainage tube.

[0004] The limb drainage tube auxiliary fixation device of the present application comprises: a shell;

[0005] The shell is made of transparent plastic and is used to cover the root of the drainage tube so that the root of the drainage tube is enclosed in the shell; the outer surface of the shell is a smooth curved surface; an extension plate is formed at the first end of the shell; an extension groove is formed at the second end of the shell; the lower side of the extension groove is open; the extension groove passes through the shell; the extension groove is used to guide the drainage tube from the shell to the outside; a first fixing belt is fixed on the extension plate; a second fixing belt is fixed on the outside of the extension groove; the first fixing belt and the second fixing belt are both composed of self-adhesive bandages; the first fixing belt is used to wrap and fix the limb and the extension plate together; the second fixing belt is used to wrap and fix the extension groove and the limb together; the second fixing belt is also used to wrap and fix the drainage tube extending from the extension groove to the outside with the limb, so that as much of the drainage tube as possible is wrapped and covered by the second fixing belt.

[0006] Preferably, an expansion edge extending horizontally outward is formed on the lower edge of the shell.

[0007] Preferably, slits or air holes are formed on the shell.

[0008] Preferably, a plurality of through holes are formed on the upper side of the extension groove, and a rubber column is installed in each through hole; the lower end of the rubber column is tightly pressed against the upper side of the drainage tube in the extension groove.

[0009] The auxiliary fixing device for limb drainage tubes of the present application covers the root of the drainage tube through a shell, which, on the one hand, protects the root of the drainage tube from being easily touched, and on the other hand, can clearly observe the condition of the drainage port at the root of the drainage tube; the auxiliary fixing device for limb drainage tubes of the present application is fixed at both ends by wrapping with self-adhesive bandages, and no adhesive is used on the skin surface, thereby ensuring heat dissipation and moisture removal from the skin surface; the auxiliary fixing device for limb drainage tubes of the present application wraps and covers as much of the drainage tube as possible through a second fixing belt, so that the drainage tube is fixed more firmly, and on the other hand, the drainage tube exposed to the outside is shorter, which increases the difficulty of tube removal.

[0015] The limb drainage tube auxiliary fixation device of the present application is described in detail below with reference to the accompanying drawings.

[0016] The auxiliary fixing device for limb drainage tube of the present application comprises: a shell 10 .

[0017] The shell 10 is made of transparent plastic and is used to cover the root of the drainage tube so that the root of the drainage tube is enclosed in the shell.

[0018] The outer surface of the shell is a smooth curved surface, such as a semi-ellipsoidal shape.

[0019] An extension plate 13 is formed at a first end of the housing 10 , and an extension slot 14 is formed at a second end of the housing 10 .

[0020] The lower side of the extension groove 14 is open; the extension groove 14 is connected to the housing 10; the extension groove 14 is used to guide the drainage tube from the housing 10 to the outside.

[0021] A first fixing belt 20 is fixed on the extension plate 12 ; and a second fixing belt 30 is fixed outside the extension groove 14 .

[0022] The first fixing belt 20 and the second fixing belt 30 are both made of self-adhesive bandages; the first fixing belt 20 is used to wrap and fix the limb and the extension plate 13 together; the second fixing belt 30 is used to wrap and fix the extension groove 14 and the limb together; the second fixing belt 30 is also used to wrap and fix the drainage tube extending from the extension groove to the outside with the limb, so that the drainage tube is wrapped and covered by the second fixing belt as much as possible.

[0023] An expansion edge extending horizontally outward is formed on the lower edge of the shell to increase the contact area and reduce the pressure.

[0024] The housing is formed with slits or air holes 11a to facilitate heat dissipation.

[0025] A plurality of through holes 14 a are formed on the upper side of the extension groove 14 , and a rubber column 14 b is installed in each through hole 14 a ; the lower end of the rubber column 14 b is tightly pressed against the upper side of the drainage tube in the extension groove.

[0026] When in use, the shell is buckled above the root of the drainage tube, and the drainage tube is led out from the extension groove to the outside; then the first fixing belt is used to wrap the shell and the limb together through the extension plate at the first end of the shell; similarly, the shell is wrapped and fixed together with the limb through the extension groove by the second fixing belt at the second end of the shell; the second fixing belt can be formed longer, not only wrapping and fixing the extension groove, but also wrapping and fixing the drainage tube extending from the extension groove with the limb, so that the fixation of the drainage tube is more stable and the drainage tube is less exposed. The upper end of the rubber column in the extension groove extends to the outside of the extension groove, and the lower end extends to the inside of the extension groove, abutting against the upper side of the drainage tube; when the second fixing belt is wrapped around the extension groove, the upper end of the rubber column is compressed by the second fixing belt, so that the lower end of the rubber column is tightly pressed on the drainage tube, making the fixation of the drainage tube more secure. The fixation of the entire device does not require glue, ensuring the breathing and heat dissipation of the patient's skin; the root of the drainage tube is covered by the shell, which is convenient for observation and not easy to be touched.
