[0024] Referring to Figure 2 , the cutting line 11 is in the form of T, the cutting line 11 comprises a longitudinal part 15 and a transverse part 16, the longitudinal part 15 is located in the bandage unit 1, and the transverse part 16 is perpendicular to the longitudinal part 15, and the left and right ends of the transverse part 16 are connected with the longitudinal part 15 and the edge of the bandage unit 1 respectively.

[0025] The utility model discloses a cutting line 11 is formed on the bandage unit 1 through cutting the bandage unit 1, compared with the existing butterfly bandage needs manual ordinary bandage to use scissors and other tools to cut, reduce the adhesion area of bandage, simultaneously, the cut off bandage part exists the situation of waste, the bandage unit 1 can use the automatic cutting station to cut and form the cutting line 11 in production, need not use manual cutting again, can improve the convenience of the utility model for use, simultaneously, cutting forms the cutting line 11 and can not form the waste material, can improve the use ratio of bandage unit 1, simultaneously, improve the adhesion area of bandage unit 1 and patient's skin to improve the fixing effect.

[0026] Referring to Figure 2 The cutting line 11 is provided with two and is symmetrically arranged left and right to the bandage unit 1, and the transverse part 16 of the two cutting lines 11 is connected with the left and right edges of the bandage unit 1 respectively.

[0027] Through the setting of the two cutting lines 11, the upper half 12 and the lower half 14 can be adhered to the skin of the patient while being overlapped with each other on the front and back sides of the catheter 3, so that the fixing effect of the upper half 12 and the lower half 14 on the front and back sides of the catheter 3 is improved, and the probability of separation between the bandage unit 1 and the skin of the patient is reduced.

[0028] Referring to Figure 2 The connecting line 2 and the cutting line 11 between the adjacent bandage units 1 are both easy-to-tear lines in a dashed line shape.

[0029] In the production of the utility model, the easy-to-tear lines are cut between the adjacent bandage units 1, so that the medical staff can easily tear off the single bandage unit 1 along the easy-to-tear lines at the end, and the convenience of use of the utility model is improved.

[0030] In the embodiment, the cutting line 11 is also an easy-to-tear line, which can be torn by the medical staff along the easy-to-tear line to form the cutting line 11, so that the situation that the winding operation of the bandage unit 1 is affected by the bending and lifting of the position of the cutting line 11 on the upper half 12 and the lower half 14 during the production of the utility model is reduced, and after the winding of the bandage unit 1, the situation that the deformation of the bandage unit 1 and the pollution of the inner layer caused by the lifting of the position of the cutting line 11 is also reduced. Therefore, compared with the mode that the cutting line 11 is directly cut during the production of the utility model, the structure of the easy-to-tear line can reduce the winding difficulty of the bandage unit 1 and prolong the storage time of the bandage unit 1.

[0031] Referring to Figure 4When a long length of catheter 3 needs to be fixed, the existing butterfly bandage needs to be cut and separated into multiple bandage units 1 to be pasted on the catheter 3 in multiple places in turn, increasing the steps and time required for fixing the catheter 3, while the utility model can tear off multiple bandage units 1 together in use, the connecting lines 2 between adjacent bandage units 1 in the torn-off part remain connected, then the cutting lines 11 in each bandage unit 1 are torn off, so that the middle part 13 of all the bandage units 1 can be pasted on the upper side of the catheter 3, and the overlapping positions of the upper half 12 and the lower half 14 of all the bandage units 1 can be bent and wound to the lower side of the catheter 3, so that the upper half 12 and the lower half 14 are pasted together and then pasted on the skin of the patient to realize fixation. Therefore, when fixing a long length of catheter 3, the utility model keeps multiple bandage units 1 connected with each other, thereby simplifying the cutting steps of the bandage and shortening the time required for fixing the catheter 3, and meanwhile, the connection between the bandage units 1 enables each bandage unit 1 to be subjected to the pulling force of the adjacent bandage unit 1, thereby improving the anti-external force pulling capacity of each bandage unit 1, and compared with the mode of fixing the catheter 3 by separating each bandage unit 1 from each other, the utility model can reduce the probability of the bandage unit 1 separating and falling off from the skin of the patient, and improve the fixing effect of the catheter 3.

[0032] Referring to Figure 5 , the bandage unit 1 comprises, from outside to inside, a base layer 17, a glue layer 18 and a separation layer 19, the glue layer 18 is arranged between the base layer 17 and the separation layer 19, and the base layer 17 and the glue layer 18 both adopt a multi-microporous breathable structure.

[0033] The separation layer 19 can cover and protect the glue layer 18, and needs to be torn off to expose the glue layer 18 in use, so that the bandage unit 1 has the effect of adhesion. The use of the multi-microporous breathable structure for the base layer 17 and the glue layer 18 can improve the breathability of the bandage unit 1 adhered to the skin of the patient, and reduce the discomfort caused by the long-term adhesion of the bandage unit 1 to the skin of the patient.

[0034] The glue layer 18 of the middle part 13 does not adopt a multi-microporous structure.

[0035] Since the middle part 13 is adhesively fixed to the catheter 3, the adhesion layer can not be arranged in a multi-microporous structure, so as to improve the adhesion area between the adhesion layer and the outer wall of the catheter 3, thereby improving the fixing effect between the middle part 13 and the catheter 3.

[0036] The base layer 17 is woven with elastic fiber filaments.

[0037] The elasticity of the base layer 17 can be improved through the elastic fiber yarn, and since the viscous layer 18 (the material is usually natural rubber or hot melt adhesive) also usually has a certain ductility, the utility model can be stretched within a certain range, so that the catheter 3 with different diameters within a certain range can be fixed, the application range of the utility model is improved, meanwhile, the utility model has elasticity, and the skin damage caused by long-time adhesion on the skin of a patient can be reduced.

[0038] The above in the specification is only an example of the utility model. The skilled in the art to which the utility model belongs can make various modifications or supplements to the described specific embodiments or adopt similar ways to replace, as long as the content of the specification of the utility model is not deviated or the range defined by the claims is not exceeded, which shall belong to the protection range of the utility model.
