In the embodiment of the present invention, 4 connecting pillars 70, 4 are disposed between the fixing bracket 10 and the adhesive tape bracket 50, and the connecting pillars 70 are arranged circumferentially around the center of the adhesive tape bracket 50. In other embodiments of the present invention, the number of connecting struts 70 is adjusted to 2, 6, etc. as needed.
1. Referring to fig. 8, the overall stress analysis of the fixing device for clinical medical drainage tube 30 provided in the embodiment of the present invention is as follows:
as shown in fig. 8, the top of the fixing bracket 10 has two force components at each side, i.e., two force components at each side, because the medical adhesive tape 60 is adhered to the skin and the fixing bracket 10Tension in the horizontal direction and compression in the vertical direction, F1 and F3 are tension in the horizontal direction, and F2 and F4 are compression in the vertical direction; and F5 and F6 are the suction force of the negative pressure suction cup 40 by the atmospheric pressure. Due to the deformation of the vacuum chuck 40, the lower port of the stent where the drainage tube 30 is located is in contact with the affected part of the patient, so that a resultant force F is formed. The resultant force F is synthesized from F2, F4, F5, F6. Wherein F2 and F4 are synthesized by a plurality of component forces of the rubberized fabric at the joint of the top of the stent, namely F2 ═ integral ^0 ∏FiFi is the vertical component of each point where the adhesive tape is connected with the bracket, and similarly, F4 ═ integral-∏ 2∏FjIn which F isjIs the vertical component force of each point of the connection between the adhesive plaster and the bracket. F5 ═ Δ P1*S1，F6＝ΔP2*S2In which Δ P1And Δ P2The pressure difference between the inside of the two negative pressure suction cups 40 and the atmospheric pressure, S1And S2The projected areas of the vacuum cups 40 on the horizontal plane are respectively.
So that F is F2+ F4+ F5+ F6
Then, F ═ n-0 ∏Fi+∫0 ∏Fj+ΔP1*S1+ΔP2*S2
Therefore, when Fi、Fj、ΔP1、S1、ΔP2、S2In both positive values, F must be greater than 0, i.e., the resultant force is directed downward. It is clear that the above values are all non-negative values, so that the fixation stent 10 can be fixed on the patient's skin 80 and can perform a fixation function.
2. Referring to fig. 9, the force applied to the drainage tube 30 of the fixing device for clinical medical drainage tube 30 provided in the embodiment of the present invention is analyzed as follows:
because the elastic sealing sleeve 20 and the drainage tube 30 are in interference fit, the drainage tube 30 receives radial pressure Ft generated by the deformation of the elastic sealing sleeve 20 on the contact surface with the elastic sealing sleeve 20 (Ft is the radial integral after the elastic deformation pressure of the contact surface between the drainage tube 30 and the elastic sealing sleeve 20 is integrated along the axial direction), and when the drainage tube 30 tries to move along the axial direction, the drainage tube 30 receives friction force Fm ═ Ft × Δ, and Δ is a friction coefficient. When the elastic sealing sleeve 20 is going to move axially along the drainage tube 30, its contact surface with the stent is subjected to an elastic deformation pressure Fk (Fk and Ft are obtained by integrating the force of each point of the sealing sleeve and the stent contact surface in the same way), and the component forces F7 and F8 of Fk are affected by the moving direction, and the value will change. Wherein, when the elastic sealing sleeve 20 moves downwards (i.e. moves towards the large port of the elastic sealing sleeve 20), F7 and F8 will rapidly become 0, whereas when moving upwards, F7 and F8 will become larger as the deformation quantity becomes larger, preventing the movement towards the direction, so that the elastic sealing sleeve 20 can only move in one direction. Since the direction of the large end and the small end of the elastic sealing sleeve 20 at the upper cover plate 11 is opposite to the direction of the large end and the small end of the elastic sealing sleeve 20 at the bottom of the stent body 12, the drainage tube 30 cannot move in the axial direction after being sleeved on the elastic sealing sleeve 20.
Referring to fig. 10, in addition, because the drainage tube 30 and the elastic sealing sleeve 20, the elastic sealing sleeve 20 and the stent are in interference fit when in use, no gap exists, and the outer circumference of the elastic sealing sleeve 20 is larger than the wound surface of the affected part, thereby achieving the sealing and leakage-proof effects.
The above mentioned is only the embodiment of the present invention, and not the limitation of the patent scope of the present invention, all the equivalent transformations made by the contents of the specification and the drawings, or the direct or indirect application in the related technical field, are included in the patent protection scope of the present invention.
