Description

Technical Field

[0001] The invention relates to the technical field of gastrointestinal surgical catheter fixation, in particular to an adjustable gastrointestinal surgical catheter fixation device. Background Art

[0002] The gastric tube is used to deliver necessary water and food to patients who cannot swallow under special circumstances. The gastric tube is generally made of polyurethane or silicone. Depending on the material, polyurethane and silicone gastric tubes should be replaced once a month. There are different specifications for thickness, length and length. The gastric tubes are orogastric tubes and nasogastric tubes. Among them, the orogastric tube is about 45cm long and can be inserted 35 to 40cm through the mouth. The nasogastric tube is about 105cm long and needs to be inserted about 55cm through the nostril, through the pharynx, through the esophagus to the stomach. The nasogastric tube is easy to fall out and should be firmly pasted to prevent repeated intubation and aspiration. It consists of a tube, a gastric tube feeding port connector, a gastric tube clamp, and a cross knot cap. When a nasogastric tube is placed in the esophagus, the patient's original digestive tract physiological environment is changed, which will lead to poor closure of the terminal esophageal sphincter, poor airway, severe coughing and other pressure stimulations that can easily lead to complications such as esophageal reflux. Gastric juice can also be extracted through the gastric tube. There are usually two feeding port connectors for a gastric tube. When the top cap is opened, you can only use a small syringe to manually pressurize the push rod and piston to inject some liquid food like water. The booster and a 100ml large syringe can be used to inject some thicker meat and vegetable foam or mechanically grind it into a paste or pasty noodles, which can increase dietary fiber, facilitate defecation, and promote digestion and nutrient supply.

[0003] In the prior art, a catheter holder for gastrointestinal surgery is disclosed in publication number "CN109364346B". The purpose of the present invention is to overcome the problems of low efficiency of two-way movement, inability to achieve normal movement, and unreasonable movement mode and limited application range caused by factors such as the fixed ring diameter being immutable in the existing catheter holder for gastrointestinal surgery. The present invention provides a catheter holder for gastrointestinal surgery, including a side surrounding positioning mechanism, a bottom carrier plate, a circumferential displacement platform, a normal rotation mechanism, and a top fixed bracket. The bottom carrier plate is movably connected to the bottom of the side surrounding positioning mechanism, the circumferential displacement platform is movably arranged above the bottom carrier plate, the normal rotation mechanism is fixedly connected to the upper surface of the circumferential displacement platform, and the top fixed bracket is movably connected to the top of the normal rotation mechanism. The present invention can realize a catheter holder for gastrointestinal surgery that can move and position in multiple directions, has normal freedom, and has an adjustable fixed diameter.

[0004] However, the existing technology still has major deficiencies, such as:

[0005] In the above-mentioned device and the prior art, the nasogastric tube needs to be slowly inserted into the patient's nasal cavity. During the insertion process, the nasogastric tube is relatively soft and easily wrinkled, which affects the air supply capacity of the nasogastric tube. At the same time, the surface of the nasogastric tube needs to be lubricated to reduce the stimulation of the patient's nasal mucosa by the insertion of the nasogastric tube. The above-mentioned technology lacks guiding technology for the nasogastric tube. If the nasogastric tube is lubricated by applying a lubricating liquid before insertion, the nasogastric tube can be lubricated. However, during the delivery of the nasogastric tube, the lubricating liquid on the surface of the nasogastric tube is difficult to retain moisture, resulting in irritation of the patient's nasal mucosa by the insertion of the nasogastric tube.

The liquid spraying bins 75 are arranged in a ring shape and are arranged in a plurality of groups, and an electromagnetic nozzle 76 is installed on the surface of the liquid spraying bin 75;

[0040] In this embodiment, when the nasogastric tube is inserted into the middle lubrication chamber 74, the spray chamber 75 and the electromagnetic nozzle 76 inside the middle lubrication chamber 74 will evenly spray the lubricating liquid on the surface of the nasogastric tube. At the same time, in order to ensure that the surface of the nasogastric tube is evenly sprayed, the primary annular guide rail 71 can be driven to rotate, and the primary annular guide rail 71 drives the rotating inner ring 72 and the connecting rod 73 to rotate. The connecting rod 73 drives the middle lubrication chamber 74 to rotate, so that the electromagnetic nozzle 76 installed in the middle lubrication chamber 74 can rotate and spray evenly, further improving the lubrication effect of the middle lubrication chamber 74 on the nasogastric tube, and further reducing the irritation of the patient's nasal mucosa caused by the insertion of the nasogastric tube.

[0041] The catheter lubrication and moisturizing guide unit is arranged on one side of the catheter delivery positioning lubrication unit, and is used to moisturize the lubricated catheter and guide and limit the active path of the catheter to ensure the insertion effect of the catheter;

[0042] The catheter lubrication and moisturizing guide unit includes a primary guide portion, which includes a guide bin 8, which is set to be conical, and the bottom of the guide bin 8 is connected and installed on one side of the middle ring body 7.

A smear roller 86 is installed on one side of the rotating end of the secondary annular guide rail 85, and the smear roller 86 is arranged at intervals of several groups.

[0043] The catheter lubrication and moisturizing guide unit also includes a secondary guide portion, which includes a support column 821 installed at the bottom of the guide cavity 82, a conveying roller 822 rotatably installed on the top of the support column 821, a support column 821 and a conveying roller 822 are also installed on the top of the guide cavity 82, a hard telescopic tube 9 is installed on the top of the guide bin 8, a nasal cannula 91 is installed at one end of the hard telescopic tube 9, and a heat preservation heat pipe 5 is installed on the surface of the guide bin 8.

[0044] Anti-skid rubber rings 92 are arranged at intervals on the surface of the nasal cannula 91 .

[0045] In this embodiment, after the nasal cannula 91 is locked in place, the electric shaft 42 is driven to rotate around the tube 43, and the driving roller 65 in the expansion cavity 64 is synchronously driven. When the driving roller 65 rotates, it will drive the nasogastric tube that is pre-clamped between adjacent guide rollers 63 to move for transportation. The nasogastric tube will slowly be inserted into the middle lubrication bin 74 and pass out from the middle lubrication bin 74. Then the nasogastric tube is inserted into the guide bin 8. The nasogastric tube is inserted into the inner cavity of the fixed outer ring 84 in the guide bin 8. At the same time, the nasogastric tube is also assisted by the adjacent conveying roller 822. After the nasogastric tube passes out of the guide bin 8, it will slowly be inserted into the hard telescopic tube 9 and inserted into the patient's nasal cavity along the hard telescopic tube 9, thereby ensuring the insertion effect of the nasogastric tube and reducing the exposure of the nasogastric tube. The lubricating fluid applied on the surface of the nasogastric tube can ensure long-term moisturizing.

[0046] Embodiment 2:

[0047] Based on the first embodiment, in order to avoid the shaking of the device during the insertion of the nasogastric tube, which may cause excessive stimulation of the patient's nasal mucosa and bleeding during the insertion of the nasogastric tube, a two-stage locking structure of the device is provided in this embodiment. In this embodiment, the locking effect of the two sections of the device can be improved by the pressurized stabilization unit and the bed guardrail locking unit, and the locking effect of the side clamping platform 2 can be improved to avoid the above-mentioned problem.

[0048] A pressurizing and stabilizing unit is provided at the bottom of the side clamping platform 2 .

[0049] The pressurized stabilization unit includes an extended pressure block 26. A bottom groove 24 is opened at the bottom of the side clamping platform 2. A movable cylinder 25 is fixedly installed inside the bottom groove 24. The extended pressure block 26 is installed on the movable end of the movable cylinder 25. A locking screw 22 is installed on the surface of the side clamping platform 2.

[0050] The surface of the center positioning ring 3 is symmetrically provided with mounting grooves 31 , and a bed guardrail locking unit is provided in the mounting grooves 31 .

[0051] The bed guardrail locking unit includes a locating pin 32, which is installed in the installation groove 31, and a limit block 321 is installed at one end of the locating pin 32. A movable arm 33 is movably sleeved on the surface of the locating pin 32, and a support spring 322 is sleeved on the surface of the locating pin 32. The two ends of the support spring 322 are respectively fixed to the limit block 321 and one side of the movable arm 33. The movable arm 33 is symmetrically arranged in two groups. An embedded guide rail 34 is installed on the movable arm 33, and an insert block 35 is installed on the movable end of the embedded guide rail 34. A slot 351 is arranged on the surface of the insert block 35.

[0052] In this embodiment, since the side clamp 2 locks the bottom of the device, during the insertion of the nasogastric tube, the area of ​​the central positioning ring 3 installed on the top of the side clamp 2 lacks fixation, so the movable arm 33 can be locked on the guardrail of the external bed 1 through the provided movable arm 33. When the movable arm 33 is locked in place, the embedded guide rail 34 installed on the movable arm 33 can be driven, and the moving end of the embedded guide rail 34 can drive the insert block 35 to move to the positioning pin 32 area, and the slot 351 on the surface of the insert block 35 will be inserted into the positioning pin 32 area, thereby locking the rotation function of the movable arm 33 to ensure the stability of the movable arm 33 during the insertion of the nasogastric tube.

[0053] Working principle: When the device is in use, the medical staff winds the required nasogastric tube onto the surface of the tube winding tube 43, and then controls the rotation of the tube winding tube 43 through the electric rotating shaft 42, thereby inserting the nasogastric tube. Then, the medical staff installs the device on the side wall of the bed on one side of the external bed 1 through the side clamping platform 2, and locks the position of the side clamping platform 2 through the clamping groove 21 and the pressure rod 27, and then tightens the locking screws 22 on both sides of the side clamping platform 2, so that the locking screws 22 are completely locked on both sides of the surface of the external bed 1;

[0054] During the insertion of the nasogastric tube, the area of ​​the central positioning ring 3 installed on the top of the side clamping platform 2 lacks fixation, so the movable arm 33 can be locked on the guardrail of the external bed 1 through the movable arm 33. When the movable arm 33 is locked in place, the embedded guide rail 34 installed on the movable arm 33 can be driven, and the moving end of the embedded guide rail 34 drives the plug block 35 to move to the area of ​​the positioning pin 32, and the slot 351 on the surface of the plug block 35 will be inserted into the area of ​​the positioning pin 32, thereby locking the rotation function of the movable arm 33;

[0055] The insertion path of the nasogastric tube is unfolded, and the medical staff assists the patient to lie on the external bed 1. After the patient lies in place, the hard telescopic tube 9 in the top area of ​​the guide bin 8 is stretched and bent, so that the nasal cannula 91 at one end of the hard telescopic tube 9 is bent toward the nasal area of ​​the patient, and then the nasal cannula 91 is inserted into the nasal cavity of the patient. The anti-slip rubber ring 92 on the surface of the nasal cannula 91 can improve the fitting effect between the nasal cannula 91 and the patient's nose;

[0056] When the nasal cannula 91 is locked in place, the electric rotating shaft 42 is driven to rotate around the tube 43, and the driving roller 65 in the expansion cavity 64 is driven synchronously. When the driving roller 65 rotates, the nasogastric tube pre-loaded between the adjacent guide rollers 63 is driven to be transported and moved. The nasogastric tube is slowly inserted into the middle lubricating bin 74 and passes through the middle lubricating bin 74. Then, the nasogastric tube is inserted into the guide bin 8. The nasogastric tube is inserted into the inner cavity of the fixed outer ring 84 in the guide bin 8. At the same time, the nasogastric tube is also guided by the adjacent conveying roller 822. After the nasogastric tube passes through the guide bin 8, it is slowly inserted into the hard telescopic tube 9 and inserted into the patient's nasal cavity along the hard telescopic tube 9.

[0057] When the nasogastric tube is inserted into the middle lubricating chamber 74, the spray chamber 75 and the electromagnetic spray head 76 inside the middle lubricating chamber 74 will spray the lubricating liquid evenly on the surface of the nasogastric tube. At the same time, in order to ensure that the surface of the nasogastric tube is evenly sprayed, the primary annular guide rail 71 can be driven to rotate, and the primary annular guide rail 71 drives the rotating inner ring 72 and the connecting rod 73 to rotate, and the connecting rod 73 drives the middle lubricating chamber 74 to rotate, so that the electromagnetic spray head 76 installed inside the middle lubricating chamber 74 can rotate and spray evenly;

[0058] When the nasogastric tube is inserted into the guide bin 8, in order to prevent the lubricating liquid on the surface of the nasogastric tube from being too thick, the secondary annular guide rail 85 drives the coating roller 86 to rotate when the nasogastric tube passes through the fixed outer ring 84. Since the coating roller 86 does not directly contact the nasogastric tube, the coating roller 86 will evenly smooth the thicker lubricating liquid on the surface of the nasogastric tube during the rotation process.

[0059] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
