Description

Technical Field

[0001] This invention relates to the field of medical device auxiliary equipment, and more specifically to a fixing device for a suction tube of a negative pressure suction device. Background Technology

[0002] In clinical intensive care units, for patients requiring suctioning, suction catheters and negative pressure suction tubes are typically only connected during suctioning procedures. Outside of suctioning, the suction tube opening remains open and lacks a designated placement location. Currently, a common clinical practice is to temporarily attach a new suction catheter to an adjacent device, allowing the suction tube to adhere to the suction catheter. This method has several drawbacks.

[0003] On the one hand, the suction catheters are haphazardly tied to the equipment and placed in a disorderly manner, which not only affects the overall cleanliness of the intensive care unit, but also makes it easy for them to get tangled with other items during the retrieval process, making it difficult for medical staff to quickly and accurately obtain the suction catheters. Especially in emergency suctioning situations, every second is crucial, and this inconvenience may delay the rescue opportunity.

[0004] On the other hand, the tip of the suction catheter is exposed to the outside for a long time without effective protective measures, making it very susceptible to contamination by bacteria and other pollutants in the surrounding environment. This can lead to the introduction of pathogens into the patient's body during subsequent use, increasing the risk of infection and other complications, which is detrimental to the patient's treatment and recovery.

[0005] Therefore, we propose a suction tube fixing device for negative pressure suction devices, which can properly fix the suction tube and effectively protect its end, while also being a convenient device for medical staff to use in emergency situations. Summary of the Invention

[0006] The present invention aims to provide a suction tube fixing device for a negative pressure suction device, in order to solve the problem that in the prior art, suction tubes are randomly tied to the equipment and placed in a messy manner, which not only affects the overall cleanliness of the intensive care unit, but also makes them easy to get tangled with other items during use. Furthermore, the ends of the suction tubes are exposed to the outside for a long time without effective protective measures, making them highly susceptible to contamination by bacteria and other pollutants in the surrounding environment. This may lead to the introduction of pathogens into the patient's body during subsequent use, increasing the risk of infection and other complications, which is detrimental to the patient's treatment and recovery.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] The technical solution provided by the present invention is: a negative pressure suction tube fixing device, including a base, a fixing device fixedly provided below the base, an automatic cap removal device movably provided on the inner wall of the base, a rotating device movably provided at one end of the base, a support plate fixedly provided on the surface of the rotating device, a plurality of clamping devices evenly provided on one side of the support plate, and a guide plate fixedly provided on one side of the support plate.

[0009] The base has an outlet at one end, a protective opening facing upwards on the surface of the base, a placement groove on the inner wall of the base, and symmetrical slots at one end of the base.

[0010] The base serves as the fundamental support structure for the entire device, supporting and connecting other components. It is made of medical-grade high-strength plastic, possessing excellent corrosion resistance and a certain degree of toughness, ensuring it will not be easily damaged during long-term use.

[0011] The outlet is located at one end of the base. Its function is to provide a channel for the removal of the cap removal plate, ensuring that the cap removal plate can smoothly pass through it after the protective cap is removed, so that the next protective cap can be moved to the protective opening for easy access by medical staff.

[0012] The protective opening, with its upward-facing orientation, is located on the base surface and serves as a passage for the protective cap to enter and exit. Its size is adapted to the protective cap, allowing the cap to be accurately placed onto the suction tube after being removed from the automatic cap removal device, thus protecting the end of the suction tube.

[0013] The placement slot is located on the inner wall of the base and is used to accommodate the automatic cap removal device. Its size is reasonably designed according to the external dimensions of the automatic cap removal device to ensure that the automatic cap removal device can be stably installed inside the base and will not be obstructed during cap removal and other operations.

[0014] The slots are symmetrically located at one end of the base, forming a snap-fit ​​relationship with the cap removal plate of the automatic cap removal device. This is used to fix the position of the automatic cap removal device, ensuring that it will not be accidentally displaced during use and guaranteeing the normal operation of the cap removal function.

[0015] Furthermore, the fixing device includes a U-shaped plate fixedly installed below the base, with threaded rods symmetrically provided on the surface of the U-shaped plate and adhesive layers symmetrically provided below the U-shaped plate;

[0016] The fixing device is used to securely install the entire device in a suitable position next to the hospital bed, so that it remains stable during use and that the device will not shake or tip over when medical staff operate it.

[0017] The U-shaped plate is fixedly installed under the base. It is U-shaped and made of metal such as stainless steel. It has sufficient strength to withstand the overall weight of the device and the external forces that may be applied during use.

[0018] The threaded rods are symmetrically arranged on the surface of the U-shaped plate and are connected to the U-shaped plate by threaded adaptation. When the device is installed at the bedside, the threaded rods can be rotated to screw them into the corresponding screw holes to fix the device to the bed surface, further enhancing the device's fixation.

[0019] The adhesive layer is symmetrically positioned under the U-shaped plate and uses medical-grade strong double-sided adhesive. When the device is placed on the wall next to the hospital bed for fixation, the adhesive layer can be tightly adhered to the vertical wall, ensuring the device is placed stably and can be used by sticking it to the wall.

[0020] Furthermore, the automatic hat-removing device includes a hat-removing box movably installed on the inner wall of the base. One end of the hat-removing box has a hat-discharge port, and a hat-removing pull ring is fixedly installed at one end of the hat-removing box. Hat-removing plates are symmetrically installed at both ends of the hat-removing pull ring. The hat-removing plates are fitted into slots. A first column is fixedly installed at one end of the inner wall of the hat-removing box. A hat-removing spring is fixedly installed on the surface of the first column. A second column is fixedly installed at one end of the hat-removing spring. A hat-removing push plate is fixedly installed at one end of the second column. The hat-removing push plate is movably fitted into the inner wall of the hat-removing box. Several hat-removing plates are evenly arranged on the inner wall of the hat-removing box. The hat-removing plates are fitted into the size of the hat-discharge port and the outlet. Protective caps are movably installed on the surface of each hat-removing plate. The protective caps are fitted into the size of the protective opening. A hat-removing cover plate is movably installed on the surface of the hat-removing box. The two ends of the hat-removing cover plate are fixedly connected to one end of the inner wall of the hat-removing box and one side of the hat-removing push plate, respectively.

[0021] The automatic cap removal device is designed to provide a disposable protective cap to the end of the suction catheter and to enable a convenient cap removal operation, effectively reducing the possibility of bacterial contamination of the suction catheter.

[0022] The cap retrieval box is installed in the placement slot on the inner wall of the base. Its external dimensions match the placement slot. It is made of transparent medical plastic, which allows medical staff to visually observe the remaining number of protective caps inside. One end of the cap retrieval box has a cap ejection port, which is used to push out the cap retrieval plate one by one after the protective cap is taken out. The size and shape of the cap ejection port are adapted to the cap retrieval plate and the subsequent outlet to ensure that the cap retrieval plate can pass through and be discharged smoothly.

[0023] The cap removal pull ring is fixed at one end of the cap removal box, providing medical staff with a convenient point of force to pull the cap removal box for installation, disassembly or adjustment. The cap removal pull ring has symmetrical cap removal plates at both ends. The cap removal plates are fitted into the slots of the base. When the cap removal box is installed in the placement slot, it can be firmly fixed to the base by the snap-fit ​​method, ensuring that it will not move at will during normal use.

[0024] The first column is fixedly installed on one end of the inner wall of the cap removal box, serving as a fixed support component for the cap removal spring. Its material is selected from plastic or metal with a certain strength to ensure that it will not be deformed or damaged during long-term use of the device, thus affecting the normal function of the cap removal spring.

[0025] One end of the cap-removing spring is fixed to the surface of the first column, and the other end is connected to the second column. Its function is to provide elastic restoring force for the cap-removing push plate, so that the protective caps can move one by one towards the cap-dispensing opening.

[0026] One end of the second column is connected to the cap-removing spring, and the other end is fixedly connected to the cap-removing push plate. It plays the role of transmitting the spring force, converting the extension and retraction of the cap-removing spring into the translational movement of the cap-removing push plate, and pushing the cap-removing plate to move the protective cap in an orderly manner toward the protective opening.

[0027] The cap removal push plate is fitted to the inner wall of the cap removal box and slides along the inner wall of the cap removal box under the action of the cap removal spring, ensuring that the cap removal plate can be pushed smoothly during the movement, so that the cap removal plate can drive the protective cap to move.

[0028] The cap removal plates are evenly distributed on the inner wall of the cap removal box. Their size is adapted to the cap ejection port and outlet. They are used to support and position the protective caps, so that the protective caps can be neatly arranged in the cap removal box and pushed out one by one through the cap ejection port in sequence. Each cap removal plate can hold one protective cap. The protective cap is made of disposable medical sterile plastic material. Its shape matches the end of the suction tube and can be tightly fitted to the end of the suction tube to play a sealing and protective role, and isolate external bacteria and other contaminants.

[0029] The cap removal cover is movably mounted on the surface of the cap removal box. Its two ends are fixedly connected to one end of the inner wall of the cap removal box and one side of the cap removal push plate, respectively. As the cap removal push plate moves, the cap removal cover moves accordingly, which covers the cap removal box and keeps the inside of the cap removal box relatively closed, thus increasing its aesthetic appeal.

[0030] Furthermore, the rotating device includes a rotating shaft that is movably mounted on one end of the base, and an adjusting wheel is fixedly provided on one end of the rotating shaft;

[0031] The rotating device allows for angle adjustment of the support plate, enabling medical staff to adjust the placement angle of the suction tube according to actual operational needs and usage scenarios, facilitating its retrieval and operation.

[0032] The rotating shaft is movably mounted on one end of the base, allowing it to rotate flexibly around its own axis. The fit between the shaft and the base is highly precise, ensuring smooth rotation while preventing loosening or excessive wobbling. An adjustment wheel is fixed at one end of the rotating shaft, facilitating precise control of the rotation angle.

[0033] Furthermore, the clamping device includes several clamping slots opened on one side of the support plate, a clamping plate is fixedly provided on the inner wall of the clamping slot, clamping rods are fixedly provided on both sides of the clamping plate, clamping blocks are movably embedded on the surface of the clamping rods, clamping springs are fixedly provided on both sides of the clamping plate, the other end of the clamping springs is fixedly connected to one side of the clamping block, the clamping springs are movably adapted to the surface of the clamping rods, a fixing clamp is fixedly provided on one side of the clamping block, a clamping slot is opened on the inner side of the fixing clamp, a clamping cover plate is provided on the surface of the clamping slot, and the two ends of the clamping cover plate are fixedly connected to the inner wall of the clamping slot and the two sides of the clamping block, respectively.

[0034] The support plate is used to support and fix the suction tube, providing a stable placement position for the suction tube. Multiple components related to the fixation of the suction tube are located on one side of the support plate. Clamping devices are evenly distributed on one side of the support plate to clamp the suction tube, ensuring that the suction tube is firmly placed on the device and will not shake or slip off. Each clamping device includes the following components working together:

[0035] The clamping plate is fixedly installed on the inner wall of the clamping groove as the main support and fixing component. Its material is medical plastic or thin metal plate with a certain rigidity, which provides the installation base for other clamping components and can withstand a certain external force to ensure the clamping effect of the suction tube.

[0036] The clamping rods are fixedly installed on both sides of the clamping plate to guide and limit the movement of the clamping block. Their smooth surfaces ensure that the clamping block can slide smoothly on them, enabling the clamping and releasing of the suction tube.

[0037] The clamping block is embedded in the surface of the clamping rod and can move back and forth on the clamping rod. It can clamp the suction tube by cooperating with other components.

[0038] One end of the clamping spring is fixedly connected to both sides of the clamping plate, and the other end is connected to one side of the clamping block. Its elasticity causes the clamping block to move towards the center of the clamping groove under normal conditions, thereby driving the fixed clamp to move and clamp the suction tube placed in the clamping groove.

[0039] The fixing clip is fixedly installed on one side of the clamping block, and a clamping groove is opened on the inner side. When in use, the clamping grooves of the two opposing fixing clips cooperate with each other to clamp the suction tube from both sides.

[0040] The two ends of the clamping cover are fixedly connected to the inner wall of the clamping groove and the two sides of the clamping block, respectively, which serves to cover and protect the internal components of the clamping device and increase the aesthetics of the device.

[0041] The guide plate is fixedly installed on one side of the support plate. The surface of the guide plate is smooth and marked with the words "Emergency Use". Below the words is an arrow pointing in the direction of extension of the guide plate. Its function is to provide guidance for the removal of the suction tube, so that the suction tube can pass smoothly through the outlet along the guide plate during the retrieval process, avoiding entanglement or jamming, and improving the convenience of retrieval.

[0042] Furthermore, a handle is fixedly provided on one side of the base, and the surface of the handle is provided with anti-slip texture and made of anti-slip material;

[0043] The handle is fixed to one side of the base and has an anti-slip texture. It is made of an anti-slip material such as rubber to make it easy for medical staff to hold. Especially when it is necessary to move or adjust the position of the device, holding the handle can make the device more stable and convenient to operate.

[0044] The beneficial effects of this technical solution are:

[0045] (1) Through various fixing methods of the fixing device, it can adapt to different bedside environments, firmly install the device in a suitable position, and will not easily shake during use, providing a stable foundation for the placement of the suction tube and subsequent operations, so that the device can be fixed to the bedside and pasted on the wall, improving the versatility and practicality of the device.

[0046] (2) The automatic cap removal device enables convenient use of the protective cap. Medical staff can easily put the protective cap on the end of the suction tube without complicated operations, which effectively reduces the chance of the suction tube being contaminated by external bacteria, ensures the hygiene of the suction tube, reduces the risk of infection for patients due to suctioning, and is beneficial to the health and recovery of patients.

[0047] (3) The clamping device can firmly clamp and fix the suction tube, ensuring that the suction tube is placed neatly and orderly on the device, and there will be no mess or tangling. With the guidance of the guide plate, it is more convenient and faster for medical staff to take the suction tube. Especially in emergency situations, the suction tube can be quickly and accurately obtained, which improves the efficiency of clinical work.

[0048] (4) The rotating device allows the angle of the support plate to be flexibly adjusted according to the actual operation scenario and the usage habits of medical staff, making it suitable for use on the bed and wall, further optimizing the convenience of placing and retrieving the suction tube, and improving the overall user experience.

[0067] The specific implementation process is as follows:

[0068] Open the cap removal cover 311 of the automatic cap removal device 3, and place the disposable sterile medical caps 309 one by one on the cap removal plates 308 inside the cap removal box 301, ensuring that the caps 309 are placed neatly and accurately. After placement, hold the cap removal pull ring 302 at one end of the cap removal box 301 and move the cap removal box 301 to the placement groove 103 on the inner wall of the base 1, so that the cap removal plates 303 on both sides of the cap removal box 301 accurately engage with the symmetrically opened grooves 104 at one end of the base 1.

At this time, the cap removal box 301 is firmly installed in the base 1, and the internal protective caps 309 can be seen through the protective opening 102 on the surface of the base 1. The cap removal box 301 will not move arbitrarily, preparing for subsequent cap removal operations.

[0069] One end of the suction tube is placed into the clamping groove 601 of the clamping device 6 evenly opened on one side of the support plate 5. When the suction tube enters the clamping groove 601, due to the elastic action of the clamping springs 605 fixed on both sides of the clamping plate 602, the clamping springs 605 push the clamping block 604 connected to it to move along the clamping rod 603 towards the suction tube, which drives the clamping groove 607 of the fixed clamp 606 to gradually clamp the suction tube until the suction tube is firmly fixed in the clamping groove 601, and one end of the suction tube is inserted into the protective cap 309.

[0070] When a suction catheter is needed, medical staff pull the suction catheter to remove the protective cap 309 from one end of the suction catheter, remove the protective cap 309, and then use the suction catheter.

[0071] After the protective cap 309 is removed, the surface of the cap removal plate 308, without the restriction of the protective cap 309, allows the automatic cap removal device 3 to push the next set of cap removal plates 308 and protective caps 309 to move below the protective opening 102. The cap removal plate 308 without the protective cap 309 is then removed through the cap discharge opening 310 and the outlet 101. After the operation is completed, the used suction tube can be discarded in accordance with the medical waste disposal regulations. If it is necessary to use this device to fix a new suction tube, the above-mentioned fixing, cap removal and retrieval operation steps can be repeated. Then the suction tube can be connected to the negative pressure suction device to start the normal suction operation.
