Detailed Description

This is described in detail below with reference to fig. 1-5.

Example 1

The present embodiments provide a medical tubing set that can be adhered to the skin of a patient or attached to a medical device worn at a corresponding intubation site of the patient. The medical device can be an elastic face sleeve (used for fixing a stomach tube) worn on the face of a patient, a waistband (used for fixing a drainage tube) worn on the waist of the patient and the like. Specifically, the method comprises the following steps: as shown in fig. 1, the medical tube fixing device includes a base 100 and an elastic groove edge 200. The back of the chassis 100 is a film that allows the fastening device to be adhered to the skin of a patient or a medical device. The clamping groove 300 is formed between the base 100 and the elastic groove edge 200. The width of the holding groove 300 and the diameter of the medical tubing 400 match each other, namely: the width is slightly smaller than the diameter (generally smaller than 2 mm-5 mm), so that the clamping groove can clamp the medical pipeline. Therefore, the fixing device can be designed into different specifications according to different medical pipelines.

Preferably, as shown in fig. 2-3 and 5, the inner side surface of the elastic slot rim 200 has several holding protrusions 200a arranged along the axis thereof. The clamping protrusion 200a mainly enables the medical tube 400 to deform to a certain extent, so that a contact surface is formed between the medical tube 400 and the clamping groove 300, and the medical tube is not easy to fall off from the clamping groove. The holding protrusion 200a is formed by a smooth curve, for example, the holding protrusion 200a may be spherical or ellipsoidal. Also, as shown in fig. 2 and 3, the grip protrusions 200a adjacent to each other are smoothly connected by the transition protrusions 200 b. On one hand, the transition protrusion 200b makes the contact surface of the clamping groove 300 and the medical tube 400 a continuous curved surface; on the other hand, the protrusion height of the grip protrusions 200a is greater than that of the transition protrusions 200b, so that the portions of the medical tubing protruding between the adjacent grip protrusions 200a are supported by the transition protrusions 200 b.

Preferably, the protrusion height of the clamping projection 200a is one fifth to one fourth of the tube diameter of the medical tube. This has the advantages that: the medical tube 400 can be relatively fixed by its own elastic deformation when the clamping action of the clamping groove 300 is obtained. As shown in fig. 1, the medical tube 400 has a substantially elliptical cross-section after receiving the function of the grasping groove 300.

Preferably, the gripping protrusion 200a and the transition protrusion 200b are both smoothly curved.

Preferably, as shown in fig. 5, the elastic groove edge 200 has at least an arc edge 200c and a straight edge 200d connected to each other. According to the observation, the medical tube 400 extends out of the human body to form an arc-shaped section, namely a straight line section, and the clamping groove 300 corresponding to the arc edge 200c is used for clamping the medical tube 400 in the arc-shaped section part, so that the medical tube 400 can keep the original shape without operations such as bending the medical tube 400, and the fluid can be more smoothly in the medical tube 400. And the holding groove 300 corresponding to the straight side 200d is used for holding the medical tube 400 in a straight line segment, so that the medical tube 400 can be extended to an external medical device (e.g., a urine bag, a nasal feeding bag, etc.). Therefore, as shown in fig. 4, the height of the arc side 200c is greater than the height of the straight side 200 d.

Preferably, the resilient slot edge 200 grips the medical tubing without the application of a force thereto. The elastic groove edge 200 can slightly expand the clamping groove 300 under the condition of applying a tensile force, so that the medical pipeline 400 is conveniently placed into the clamping groove 300; then, the pulling force is removed, and the elastic groove edge 200 clamps the medical tube 400.

Preferably, the chassis 100 and the elastic channel edge 200 are integrally connected. The base 100 and the elastic groove edge 200 may be integrally molded by injection molding.
