Description

Technical Field

[0001] This invention belongs to the field of medical and nursing technology, specifically referring to a catheter fixation frame for neurosurgical nursing. Background Technology

[0002] Neurosurgical care often involves intravenous infusions or drainage, requiring catheter fixation and guidance to prevent tangling and bending during patient movement. Current techniques often use tape to secure the catheter to the patient's skin. This method is inconvenient for repositioning the catheter, causes skin discomfort, and is painful to remove. Using clamps for catheter fixation can easily lead to catheter collapse, causing deformation or blockage of the internal flow channel.

[0003] Therefore, a catheter fixation device for neurosurgical care is needed to address the above problems. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a catheter fixation frame for neurosurgical care. Airflow enters the control cylinder, and the ventilation tube one and ventilation tube two are alternately ventilated by the pneumatic alternating sealing mechanism. Two sets of Bernoulli suction cups are alternately attached to the patient's skin, which can not only guide and fix the catheter, avoiding the catheter from tangling and bending, but also solve the problems of skin discomfort and catheter collapse caused by traditional fixation methods.

[0005] The technical solution adopted by this invention is as follows: This invention proposes a catheter fixation frame for neurosurgical care, including a support plate. The lower wall of the support plate is provided with a guide clamp. The upper wall of the support plate is rotatably provided with two rotating arm assemblies. The middle parts of the two rotating arm assemblies are cross-rotatably set on the upper wall of the support plate through a central axis. The ends of the rotating arm assemblies are provided with Bernoulli suction cups. The upper rotating arm assembly is provided with a control cylinder. The two rotating arm assemblies are respectively connected to the outer wall of the control cylinder through a first ventilation pipe and a second ventilation pipe. The upper end of the control cylinder is provided with an air inlet pipe, and the air inlet pipe is provided with a switch valve. The control cylinder is provided with a pneumatic alternating sealing mechanism. The pneumatic alternating sealing mechanism includes a power transmission component and a sealing transmission component, and the power transmission component is connected to the sealing transmission component.

[0006] Furthermore, the power transmission assembly includes an upper fixed plate, a lower fixed plate, fan blades, a drive shaft, and a reducer. The upper and lower fixed plates are fixed to the inner walls of the control cylinder. The upper end of the drive shaft is rotatably mounted on the lower wall of the upper fixed plate, and the lower end of the drive shaft passes through the lower fixed plate. The fan blades are mounted on the drive shaft, and the reducer is mounted on the lower wall of the lower fixed plate. The lower end of the drive shaft is connected to the input end of the reducer.

[0007] Furthermore, the sealing transmission assembly includes a rotating shaft, a gear shaft, a sealing plate, a bevel gear disk, a bevel gear, an incomplete gear, a rack, a connecting column, a connecting plate, and a support rod. The upper end of the rotating shaft is connected to the output end of the reducer. The bevel gear disk is located at the lower end of the rotating shaft. Four support rods are provided at equal intervals on the inner bottom wall of the control cylinder. The gear shaft passes through the upper end of the support rod. The bevel gear is located at the inner end of the gear shaft and meshes with the bevel gear disk. The incomplete gear is located at the outer end of the gear shaft. The racks are arranged in pairs on both sides of each incomplete gear. The outer wall of the sealing plate has the same shape as the inner wall of the control cylinder and slides along the inner wall of the control cylinder. The sealing plate and the rack are fixed by the connecting column. The ends of adjacent racks are fixed by the connecting plate. The racks on both sides alternately mesh with the incomplete gears. When half of the teeth of the incomplete gear are directly opposite the rack, the sealing plate is exactly between the connection point of the first and second vent pipes and the control cylinder.

[0008] Furthermore, the rotating arm assembly includes a rotating plate, a movable sleeve, a fixed rod, and a connecting tube. The rotating plate is rotatably mounted on a central shaft. The movable sleeve is a hollow cavity with one open end. The closed end of the movable sleeve is hinged to the end of the rotating plate. The fixed rod is composed of a straight rod and a bent rod. The straight rod is slidably mounted inside the movable sleeve. The interiors of the straight rod and the bent rod are hollow structures. The lower end of the bent rod is a closed end. The Bernoulli suction cup is connected to the lower end of the bent rod via a ball joint. The two ends of the connecting tube are respectively connected to the lower end of the bent rod and the Bernoulli suction cup.

[0009] Furthermore, the movable sleeve in the upper rotating arm assembly is connected to the upper part of the control cylinder through vent pipe one, and the movable sleeve in the lower rotating arm assembly is connected to the lower part of the control cylinder through vent pipe two.

[0010] Furthermore, a locking screw is provided on the upper wall of the open end of the movable sleeve.

[0011] Furthermore, the two rotating plates are stacked and rotatably mounted on a central axis, with the lower end of the central axis fixed to the upper wall of the support plate.

[0012] The beneficial effects achieved by the present invention using the above structure are as follows: 1. It abandons the method of directly fixing the patient's skin with tape and uses Bernoulli suction cups for fixation. The two sets of Bernoulli suction cups are alternately attached to the patient's skin through the wind-driven alternating sealing mechanism, which avoids the pressure or damage to the skin caused by long-term attachment of a single suction cup. It fundamentally solves the skin discomfort caused by tape fixation and the pain caused by tearing the tape. 2. No need to use traditional clamps to hold and fix the catheter. The guide clamps and the overall frame structure limit and guide the catheter, eliminating the problem of excessive clamping force causing the catheter to collapse, the flow channel to deform or block, thus ensuring the normal use of the catheter. 3. The two rotating arm assemblies can rotate crosswise around the central axis and the crosswise angle can be adjusted. The fixed rod in the rotating arm assembly can slide in the movable sleeve. The movable sleeve is hinged to the rotating plate and the Bernoulli suction cup is hinged to the bent rod ball. With the fixing effect of the locking screw, the suction position of the fixation frame, the arm length and the suction cup angle can be flexibly adjusted according to the patient's body part and nursing needs, with strong adaptability. 4. Powered by external high-pressure gas, the ventilation tube is alternately ventilated through the mechanical transmission of the wind-driven alternating sealing mechanism. The two sets of suction cups can be alternately adsorbed without frequent manual operation. The adsorption process is stable, and the Bernoulli suction cup adsorption method is more reliable than the traditional fixation method, and will not cause hard damage to the patient.

[0020] like Figure 2 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the sealing transmission assembly 12 includes a rotating shaft 18, a gear shaft 19, a sealing plate 20, a bevel gear 21, a bevel gear 22, an incomplete gear 23, a rack 24, a connecting column 25, a connecting plate 26, and a support rod 27. The upper end of the rotating shaft 18 is connected to the output end of the reducer 17. The bevel gear 21 is located at the lower end of the rotating shaft 18. Four support rods 27 are provided at equal intervals on the inner bottom wall of the control cylinder 6. The gear shaft 19 passes through the upper end of the support rod 27. The bevel gear 22... Located at the inner end of gear shaft 19, bevel gear 22 meshes with bevel gear disk 21. Incomplete gear 23 is located at the outer end of gear shaft 19. Racks 24 are arranged in pairs on both sides of each incomplete gear 23. The outer wall of sealing plate 20 has the same shape as the inner wall of control cylinder 6 and slides along the inner wall of control cylinder 6.

When half of the teeth of the incomplete gear 23 are directly opposite the rack 24, the sealing plate 20 is exactly between the connection between the first vent pipe 7 and the second vent pipe 8 and the control cylinder 6.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the rotating arm assembly 3 includes a rotating plate 28, a movable sleeve 29, a fixed rod 30, and a connecting pipe 31. The rotating plate 28 is rotatably mounted on the central shaft 4. The movable sleeve 29 is a hollow cavity with one open end. The closed end of the movable sleeve 29 is hinged to the end of the rotating plate 28. The fixed rod 30 is formed by connecting a straight rod 32 and a bent rod 33. The straight rod 32 is slidably mounted inside the movable sleeve 29. The interiors of the straight rod 32 and the bent rod 33 are hollow structures. The lower end of the bent rod 33 is a closed end. The Bernoulli suction cup 5 is connected to the lower end of the bent rod 33 via a ball joint. The two ends of the connecting pipe 31 are respectively connected to the lower end of the bent rod 33 and the Bernoulli suction cup 5.

[0022] like Figure 1 As shown, the upper wall of the open end of the movable sleeve 29 is provided with a locking screw 34. The length of the straight rod 32 inside the movable sleeve 29 is adjusted, and the position of the straight rod 32 is fixed by the locking screw 34.

[0023] like Figure 1 and Figure 4 As shown, the two rotating plates 28 are stacked and rotated on the central shaft 4, and the lower end of the central shaft 4 is fixed to the upper wall of the support plate 1.

[0024] In practical use, the air inlet pipe 9 is connected to the external high-pressure gas, the switch valve on the air inlet pipe 9 is opened, and the tube is passed through the guide clamp 2. The angle of the intersection of the two rotating plates 28 is controlled, and the length of the straight rod 32 in the movable sleeve 29 is adjusted so that the four Bernoulli suction cups 5 are pressed into the appropriate position on the patient's body. The high-pressure gas is turned on, and the gas enters the control cylinder 6 through the air inlet pipe 9. The airflow drives the fan blade 15 to rotate, and the fan blade 15 drives the drive shaft 16 to rotate.

Inside the Bernoulli suction cup 5, the Bernoulli suction cup 5 adheres to the patient's skin. When the incomplete gear 23 continues to rotate and engages with the rack 24 on the other side, the rack 24 moves downward. The rack 24 drives the connecting post 25 and the sealing plate 20 to move downward. When the sealing plate 20 is between the ventilation tube 1 7 and the ventilation tube 2 8 and the control cylinder 6, all four Bernoulli suction cups 5 simultaneously adhere to the patient's skin. The rack 24 continues to move downward, driving the connecting post 25 and the sealing plate 20 to continue moving downward. The sealing plate 20 blocks the ventilation tube 2 8, and ventilation begins. When tube 7 is in a ventilated state, gas enters the corresponding movable sleeve 29 through the ventilation tube 7, then passes through the movable sleeve 29, straight rod 32, and curved rod 33 into the connecting tube 31, and finally into the Bernoulli suction cup 5. The Bernoulli suction cup 5 is attached to the patient's skin. During the rotation of the incomplete gear 23, the two sets of Bernoulli suction cups 5 are alternately attached to the patient's skin, thereby avoiding long-term attachment of the Bernoulli suction cups 5 to the patient's skin and preventing damage. Multiple such fixation devices can be used to attach to the patient's skin to guide the catheter.
