Description

Fixed decompression device for medical drainage tube

The new model relates to a care product, in particular to a fixed decompression device for a medical drainage tube.

Drainage tubes are mainly placed in human tissues or specific body cavities, thereby draining blood, tissue fluid, secretions and other liquids to avoid accumulation in specific parts of the body and cause adverse symptoms such as compression and irritation of organs. Since most of the drainage tubes need to be indwelled for a period of time, how to fix the drainage tubes will inevitably greatly affect the comfort of the user.

At present, the most traditional way of fixing the drainage tube is to attach a part of the drainage tube to the human body through tape, so that the drainage tube inserted by the user is less likely to be accidentally pulled off. When the tape is removed, the skin surface is damaged, and the drainage tube is directly fixed on the contacted skin, which is also prone to pressure injury.

As shown in FIG. 1 , it is an existing medical pipeline fixing clip 1 , which includes a sheet-shaped base 11 suitable for being fixed to the human body, and a clamping member 12 connected to the sheet-shaped base 11 . As long as the sheet-like base 11 is fixed to the human body by means of sticking, the medical pipeline, such as a drainage tube, can be fixed through the clamping member 12 in a more flexible positioning way relative to the sticking. described medical lines.

However, the sheet-like base 11 is made of a relatively hard plastic material, so when it is attached to the human body for a long time, it will inevitably cause pressure injury. Therefore, even though the medical pipeline fixing clip 1 provides a specialized fixing mechanism, it does not take into account the comfort of the user and still needs to be further improved.

Therefore, the purpose of the present invention is to provide a fixed decompression device for a medical drainage tube that is easy to use and can improve user comfort.

Therefore, the fixed decompression device of the novel medical drainage tube includes a base foam having an attaching surface and an outer surface opposite to the attaching surface, and a base foam disposed on the attaching surface of the base foam. pressure-sensitive adhesive, and a fixing member disposed on the outer surface of the base foam.

The pressure-sensitive adhesive can produce stickiness under certain pressure.

The fixing piece includes a plate-shaped sheet body fixed on the outer surface, and a ring buckle connected to the sheet body and surrounding and defining a positioning space with an opening away from the sheet body.

The effect of the new model is: when using the pressure-sensitive adhesive, the base foam can be fixed on the human body with a certain pressure, and then the medical drainage tube can be fixed with the fixing piece. It is very convenient to use without the need for additional accessories. In addition, when the base foam is attached to the human body, compared with contacting the human body with a hard material, the comfort during use can be significantly improved, and the risk of pressure injury can be thereby reduced.

Before the present invention is described in detail, it should be noted that in the following description, similar elements are designated by the same reference numerals.

Referring to FIG. 2 , it is a first embodiment of a fixed decompression device for a novel medical drainage tube. The first embodiment includes an adhesive surface 21 and an outer surface 22 opposite to the adhesive surface 21 . The base foam 2 , a pressure-sensitive adhesive 3 disposed on the attaching surface 21 of the base foam 2 , and a fixing member 4 disposed on the outer surface 22 of the base foam 2 . In this embodiment, the base foam 2 is attached to the human body through the pressure-sensitive adhesive 3 , and a drainage tube 9 is positioned by the fixing member 4 to be described.

The base foam 2 is preferably rectangular. In terms of the physical parameters of the material, it is considered that it is more suitable for the specification of the drainage pipe fitting 9. The backwash coefficient is less than 10%, the thickness is 1~5 mm, and the density is 0.15~ 0.45g/cm ³ , and the hardness measured by ASKER F-type durometer is 8~50. In addition, the water absorption rate of the base foam 2 is 8 to 15 times, and the water vapor transmission rate of the 24-hour contact with liquid is 500 to 1000 g/m ² , so that when it is attached to the human body, it can slightly absorb the metabolism of the human body. The moisture of sweat is expelled outward through the property of water vapour penetrating. In addition to preventing the moisture from accumulating on one side of the attaching surface 21 and affecting the viscosity of the pressure-sensitive adhesive 3, it can also produce a certain ventilation effect to optimize the comfort of attaching.

The pressure-sensitive adhesive 3 is preferably made of acrylic or silicone material, which can produce adhesion under a certain pressure, and it is particularly preferred that the applied pressure can be maintained for 2 to 10 seconds, which is optimized and adhered to. Therefore, the physical properties of the base foam 2 can be matched, and the operation of attaching the first embodiment to the human body can be conveniently completed under the condition of a little force. In addition, the peeling force of the pressure-sensitive adhesive 3 is 7.50~11.25N/25mm, which means that for every 25 millimeters (mm) of material, the external force required for 180-degree reverse tearing is 7.5~11.25 Newtons (N). Thereby, the skin of the human body can be prevented from being damaged when the first embodiment is torn off.

The fixing member 4 includes a plate-shaped sheet body 41 fixed on the outer surface 22 , and a ring buckle 42 integrally formed with the sheet body 41 and defining a positioning space 400 around it. The ring buckle 42 has a main body portion 421 extending along an auxiliary line L and having a C-shaped cross section, so that the defined positioning space 400 has an opening 401 facing away from the sheet body 41 . The elasticity of the main body portion 421 is Young's modulus of 1-5GPa, so as to match the specification range of the medical drainage tube that may be matched, and under the condition of ensuring stable fixation, it also avoids compressing the medical drainage tube and affecting the fundamental the evacuation function. In the first embodiment, the fixing member 4 is made of polyethylene (PE) adhesive, so that the sheet body 41 can be stably fixed on the base foam 2 .

Referring to FIG. 2 and FIG. 3 at the same time, when the drainage pipe 9 is to be fixed, the drainage pipe 9 can be conveniently entered into the positioning space 400 through the opening 401 . Due to the different diameters of the drainage pipe 9, the main body 421 can also be used to force the annular buckle 42 to slightly expand the opening 401, thereby making the drainage pipe 9 with a wider diameter. It can be accurately positioned in the positioning space 400 , and is slightly clamped by the ring buckle 42 to produce a limiting effect. In addition, when the drainage tube 9 is to be disassembled, since the sheet body 41 extends from the left and right sides of the ring buckle 42 for a certain distance, the user can conveniently apply downward force with, for example, the index finger and the middle finger. At this time, as long as an upward force is applied to the drainage pipe 9 , the drainage pipe 9 can be separated from the positioning space 400 upward from the opening 401 .

Taking the case where the drainage tube 9 is a nasogastric tube, although the nose is more concave and convex than other parts, the base foam 2 can still be firmly attached due to the flexibility and elasticity of the base foam 2. , and the drainage tube 9 is positioned through the fixing member 4 . According to the actual use of the first embodiment to fix the nasogastric tube, after the actual operation of 40 cases, the mucosal pressure injury caused by the nasogastric tube has never occurred, so the first embodiment is not only convenient to operate, but also can indeed Greatly reduces the chance of crushing injuries.
