Abstract
Description
Technical Field
[0001] This invention relates to the field of medical device technology, and in particular to a support for a ventilator extension tube. Background Technology
[0002] Ventilators are commonly used medical devices and are widely used in respiratory failure caused by various reasons, respiratory management during major surgery, respiratory support therapy, and emergency resuscitation. They occupy a very important position in the field of modern medicine.
[0003] In clinical practice, for some patients who have undergone oral or nasal endotracheal intubation, when using invasive ventilator-assisted breathing, in order to prevent the ventilator tubing from pulling on the endotracheal tube and to facilitate sputum suction, a ventilator extension tube is usually used to connect the endotracheal tube end and the ventilator tubing end.
[0004] Currently, in clinical practice, the ventilator extension tube rests directly on the patient due to its own weight, causing an angle between the extension tube and the ventilator pathway. This compromises effective ventilation and increases traction on the endotracheal tube. Furthermore, for patients who are bedridden for extended periods or require ventilator use after surgery, the prolonged contact between the ventilator tubing and their body, coupled with the patient's limited mobility, makes the areas in contact with the tubing highly susceptible to pressure injuries. Summary of the Invention
[0005] The purpose of this invention is to provide a support for a ventilator extension tube, thereby solving the aforementioned problems.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0007] This invention discloses a support for a ventilator extension tube, comprising an arc-shaped chest-fitting assembly. A binding and fixing assembly is connected to the bottom of the chest-fitting assembly. A mounting plate is connected to the top center of the chest-fitting assembly, and a lifting assembly is connected to the mounting plate. A support assembly is rotatably connected to the top of the lifting assembly. The support assembly includes a mounting base, on which two symmetrically arranged deformable arc-shaped clamps are connected. A force-bearing plate is connected to the bottom of the outer wall of each arc-shaped clamp. A condensate collection assembly is connected to the front end of the mounting plate. A pressure sensor is provided on the top surface of the mounting base between the two arc-shaped clamps. The pressure sensor has its own power supply, and a support plate is connected to the top surface of the pressure sensor. The pressure sensor is electrically connected to an alarm connected to the chest-fitting assembly.
[0008] Furthermore, the chest-fitting component includes a U-shaped PVC shell, with a medical-grade silicone foam inner layer on the inner wall of the PVC shell. A non-woven fabric layer is wrapped around the end face of the medical-grade silicone foam inner layer away from the PVC shell. Honeycomb-shaped ventilation holes are provided on the PVC shell and the medical-grade silicone foam inner layer. The binding and fixing component is connected to the bottom of the PVC shell, and the mounting plate is fixed at the top center of the PVC shell.
[0009] Furthermore, the thickness of the PVC outer shell is 1-3mm, the thickness of the medical silicone foam inner layer is 3-5mm, the diameter of the vent holes is 1-2mm, and the spacing between the holes is 3-4mm.
[0010] Furthermore, the binding and fixing assembly includes two fixing straps connected to the bottom of the chest-fitting assembly, and buckles are connected to the other ends of the two fixing straps.
[0011] Furthermore, the lifting assembly includes a column whose bottom is connected to the top surface of the mounting plate and an adjusting cap fastened to the top of the column. The column has several equally spaced adjusting holes, and the adjusting cap has a locking hole that is open at both the front and back. The adjusting cap is fixed to the column by a pin passing through the locking hole and one of the adjusting holes. The top of the adjusting cap is connected to a lifting plate, and the bottom of the mounting base is rotatably connected to the top surface of the lifting plate.
[0012] Furthermore, the bottom of the mounting base is rotatably connected to the top surface of the lifting plate via a rotating assembly. The rotating assembly includes a rotating plate and a rotating shaft. One end of the rotating shaft is connected to the bottom of the rotating plate, and the other end of the rotating shaft is rotatably connected to the top surface of the lifting plate via a bearing.
[0013] Furthermore, the rotating plate is fixed to the lifting plate by a locking assembly, the locking assembly including a locking pin, the rotating plate having an insertion hole, and the top surface of the lifting plate having a plurality of locking slots, the bottom of the locking pin passing through the insertion hole and inserting into one of the locking slots.
[0014] Furthermore, a reinforcing rib is provided between the top of the arc-shaped clamp and the load-bearing plate, and a reinforcing plate is provided between the bottom of the arc-shaped clamp and the top surface of the mounting base.
[0015] Furthermore, the mounting base, arc-shaped clamp, pressure plate, reinforcing rib, and reinforcing plate are integrally formed structures.
[0016] Furthermore, the condensate receiving assembly includes a hinge plate connected to the front end face of the mounting plate, a hinge shaft is connected through the hinge plate, hinge members are connected to both ends of the hinge shaft, and a water receiving groove is connected to the end of the hinge member away from the hinge plate.
[0017] Compared with the prior art, the beneficial technical effects of the present invention are as follows:
[0018] This invention allows the support device to be placed on the patient's chest, making the extension tube nearly parallel to the patient, ensuring effective ventilation, reducing traction on the endotracheal tube, and preventing the extension tube from pressing on the patient's body, thus avoiding pressure injury. Furthermore, if the patient rotates their body or head significantly, the extension tube will also rotate with the rotation component without affecting ventilation. The support height can also be adjusted via the lifting component to adapt to different situations. Attached Figure Description

Detailed Implementation
[0026] like Figure 1-5As shown, a support for a ventilator extension tube includes an arc-shaped chest-fitting assembly. The chest-fitting assembly includes a U-shaped PVC outer shell 5. A medical-grade silicone foam inner layer 6 is provided on the inner wall of the PVC outer shell 5. A non-woven fabric layer 7 is wrapped around the end face of the medical-grade silicone foam inner layer 6 away from the PVC outer shell 5. Honeycomb-shaped ventilation holes 8 are formed on the PVC outer shell 5 and the medical-grade silicone foam inner layer 6. A binding and fixing assembly is connected to the bottom of the PVC outer shell 5, and a mounting plate 1 is fixed to the top center of the PVC outer shell 5. The honeycomb-shaped ventilation holes 8 improve breathability and prevent sweating at the point where the non-woven fabric layer 7 contacts the patient's chest.
[0027] The thickness of the PVC outer shell 5 is 1-3mm, the thickness of the medical silicone foam inner layer 6 is 3-5mm, the diameter of the vent holes 8 is 1-2mm, and the spacing between the holes is 3-4mm.
[0028] The bottom of the chest-fitting component is connected to a binding and fixing component, which includes two fixing straps 9 connected to the bottom of the chest-fitting component. The other end of the two fixing straps 9 is connected to a buckle 10. The PVC shell 5 can be connected to the patient through the fixing straps 9 and the buckle 10.
[0029] A mounting plate 1 is connected to the top center of the chest-adhesive assembly. A lifting assembly is connected to the mounting plate 1, and a support assembly is rotatably connected to the top of the lifting assembly. The support assembly includes a mounting base 2, on which two symmetrically arranged deformable arc-shaped clamps 3 are connected. A force-bearing plate 4 is connected to the bottom of the outer wall of each arc-shaped clamp 3. A pressure sensor 23 is provided on the top surface of the mounting base 2 between the two arc-shaped clamps 3. The pressure sensor 23 has its own power supply, and a support plate 24 is connected to the top surface of the pressure sensor 23. The pressure sensor 23 is electrically connected to an alarm connected to the chest-adhesive assembly. The alarm is connected to the PVC shell 5, the specific structure of which is not shown in the figure. When there are water droplets inside the extension tube, the weight of the extension tube will increase. When the pressure sensor 23 senses the pressure change reaching the set value, the alarm will sound to alert medical staff.
[0030] The lifting assembly includes a column 19 connected to the top surface of the mounting plate 1 at its bottom and an adjusting cap 20 fastened to the top of the column 19. The column 19 has several equally spaced adjusting holes 21, and the adjusting cap 20 has a locking hole that is open at both the front and back. The adjusting cap 20 is fixed to the column 19 by a pin passing through the locking hole and one of the adjusting holes 21. The top of the adjusting cap 20 is connected to a lifting plate 22. According to the actual situation, a suitable adjusting hole 21 can be selected to fix the height of the adjusting cap 20, thereby adjusting the height of the support assembly.
[0031] The bottom of the mounting base 2 is rotatably connected to the top surface of the lifting plate 22 via a rotating assembly. The rotating assembly includes a rotating plate 11 and a rotating shaft. One end of the rotating shaft is connected to the bottom of the rotating plate 11, and the other end of the rotating shaft is rotatably connected to the top surface of the lifting plate 22 via a bearing. When the patient turns their head, the two arc-shaped clamps 3 drive the extension tube to rotate via the rotating shaft, preventing the patient from pulling on the extension tube while rotating, thus affecting the gas supply.
[0032] The rotating plate 11 is fixed to the lifting plate 22 by a locking assembly, which includes a locking pin. The rotating plate 11 has an insertion hole 13, and the top surface of the lifting plate 22 has several locking slots 14. The bottom of the locking pin passes through the insertion hole 13 and is inserted into one of the locking slots 14. When the patient remains still for a long time, the position of the rotating plate 11 can be fixed by inserting the locking pin into the insertion hole 13 and the locking slot 14.
[0033] The front end of the mounting plate 1 is connected to a condensate collection assembly, which includes a hinge plate connected to the front end face of the mounting plate 1. A hinge shaft is connected through the hinge plate, and hinge members 17 are connected to both ends of the hinge shaft. A water collection trough 18 is connected to the end of the hinge member 17 away from the hinge plate. In use, the water collection trough 18 can collect condensate falling from the insertion end of the extension tube, preventing condensate from falling directly onto the patient's body.
[0034] A reinforcing rib 15 is provided between the top of the arc-shaped clamping plate 3 and the force-bearing plate 4, and a reinforcing plate 16 is provided between the bottom of the arc-shaped clamping plate 3 and the top surface of the mounting base 2. The mounting base 2, the arc-shaped clamping plate 3, the pressure-bearing plate 4, the reinforcing rib 15 and the reinforcing plate 16 are integrally formed structures.
[0035] The operation process of this invention is as follows:
[0036] In use, place the PVC outer shell 5 on the patient's chest, so that the non-woven fabric layer 7 adheres to the chest. Then, wrap the two fixing straps 9 around the patient's back and fix them with buckles 10. The length of the fixing straps 9 can be adjusted according to the patient's chest circumference. Then, press the two force plates 4 to increase the distance between the tops of the two arc-shaped clamps 3. Then, place the extension tube between the two arc-shaped clamps 3. Open the force plates 4, and the two arc-shaped clamps 3 will return to their original position. The extension tube body is clamped by the two arc-shaped clamps 3. Adjust the height of the adjusting cap 20 according to the actual situation. At this time, place the water tank 18 between the patient's chest and chin, and then place the end of the extension tube at the patient's mouth and nose.
