Abstract
Description
Technical Field
[0001] The invention relates to the technical field of jejunal tube placement equipment, and in particular to a handheld bedside visualized jejunal tube placement device. Background Art
[0002] Jejunal tube placement is a medical procedure that is usually used for patients who cannot eat orally or cannot be fed through nasogastric feeding. A tube is inserted into the jejunum of the small intestine through the nasal cavity or direct percutaneous puncture to provide nutritional support or other treatment measures. This procedure is generally performed by professional medical staff. After the patient undergoes jejunal tube placement, attention should be paid to catheter care, monitoring for complications, and following specific diet or feeding instructions.
[0003] Blind insertion of a jejunal tube refers to the process of inserting a jejunal feeding tube into the jejunum without endoscopic guidance, based on anatomical landmarks and the operator's experience. Jejunal tube guidance usually refers to the method of tube insertion under the guidance of imaging such as gastroscopy and X-rays. This approach can more accurately place the feeding tube at the target location and reduce the risk of complications. However, the accuracy rate is low during blind insertion, and high operator experience is required. The equipment involved in X-ray guidance is large and inconvenient to move, and it is impossible to accurately determine the position of the end of the jejunal tube. It is also less suitable for critically ill patients who are not suitable for transfer; gastroscopy guidance needs to be completed by a doctor and is not widely used. Summary of the invention

[0021] like Figure 1 and Figure 3As shown, the handheld bedside visualized jejunal tube placement device comprises a visual unit 1, a fixing unit 2 and a jejunal tube 3. The fixing unit 2 is connected to one end of the jejunal tube 3, and the top of the visual unit 1 is a display panel 11, which is connected to the flexible insertion tube 5 through the handle 4. An auxiliary channel 53 is provided in the center of the flexible insertion tube 5, and a light source 12 and a camera 13 are provided at intervals at the end of the flexible insertion tube 5 at the edge of the auxiliary channel 53. An elastic airbag 51 is sleeved at the lower part of the flexible insertion tube 5, and the air inlet 54 of the elastic airbag 51 is connected to the air inlet pipe 55 outside the auxiliary channel 53, and the auxiliary channel 53 is connected to the auxiliary inlet on one side of the handle 4.
[0022] The visual unit 1 collects and presents the image of the environment at the end of the flexible insertion tube 5. The fixing unit 2 and the elastic airbag 51 fix the two ends of the jejunal tube 3 to the handle 4 and the flexible insertion tube 5 respectively, to prevent the jejunal tube 3 from being displaced relative to the flexible insertion tube 5 during the entry process, thereby affecting the accuracy of the insertion position of the jejunal tube 3. The light source 12 at the end of the flexible insertion tube 5 illuminates the entry position, and the camera 13 collects and transmits the image of the illuminated area to the display panel 11. Image collection and transmission are prior arts and are not described in detail here. A water injection tube or an air injection tube can be inserted into the auxiliary channel 53 to promote gastric peristalsis by water injection or air injection.
[0023] The catheter placement device is portable and movable as a whole, which is convenient for catheter placement for patients who are inconvenient to move. The material of the flexible insertion tube 5 is corrosion-resistant material to prevent the flexible insertion tube 5 from being corroded by gastric acid after entering the stomach and causing damage. The flexible insertion tube 5 is detachably connected to the handle 4, and the detachable connection structure is a prior art. The flexible insertion tube 5 is disassembled after use and disinfected.
[0024] like Figure 2 As shown, the fixing ring clamp 21 of the fixing unit 2 is connected to the fixing ring groove 41 of the handle 4, and the second ring clamp claw 23 of the fixing ring clamp 21 has the same structure as the first ring clamp claw 22. The first ring clamp claw 22 is hinged to one end of the first connecting rod 24, and the other end of the first connecting rod 24 is hinged to one end of the second connecting rod 25, and the other end of the second connecting rod 25 is connected to the moving block 29 of the clamping cylinder 28.
[0025] like Figure 5 As shown, the limiting rod 26 connected to the second connecting rod 25 is hinged to the fixed platform 27, the limiting rod 26 is fixedly connected to the first connecting rod 24, the fixed platform 27 is connected to the handle 4 above the fixed ring groove 41, and the fixed platform 27 is provided with a clamping cylinder 28 in the center of the two limiting rods 26.
[0026] The fixed ring clamp 21 is opened or closed relative to the fixed ring groove 41, thereby clamping and connecting one end of the jejunal tube 3 to the fixed ring groove 41. During the clamping process, the clamping cylinder 28 is started to drive the moving block 29 to move in the direction close to the handle 4, and the second connecting rod 25 rotates accordingly. The rotation of the second connecting rod 25 drives the limiting rod 26 to rotate, thereby driving the first connecting rod 24 to rotate through the limiting rod 26. The rotated first connecting rod 24 drives the first ring clamp 22 to approach the fixed ring groove 41, thereby clamping the jejunal tube 3 between the first ring clamp 22 and the fixed ring groove 41. The clamping process of the second ring clamp 23 is the same as that of the first ring clamp 22. The first ring clamp 22 and the second ring clamp 23 move synchronously to clamp the jejunal tube 3.
[0027] The first U-shaped groove 210 of the first connecting rod 24 is hinged to the first rotating rod of the first ring jaw 22, and the first ring jaw 22 and the second ring jaw 23 match the curvature of the fixed ring groove 41. The first U-shaped groove 210 is hinged to the upper and lower sides of the first rotating rod at the same time, which improves the stability of the first connecting rod 24 when driving the first ring jaw 22 to move.
[0028] like Figure 4 As shown, the jejunal tube 3 is sleeved outside the flexible insertion tube 5, one end of the jejunal tube 3 is connected to the fixed ring groove 41 through the fixed ring clamp 21, and the lower part of the flexible insertion tube 5 is in contact with the lower part of the jejunal tube 3 through the elastic airbag 51. The two ends of the jejunal tube 3 are fixed by the fixed ring clamp 21 and the elastic airbag 51 respectively, so that the position of the jejunal tube 3 and the flexible insertion tube 5 is fixed, avoiding relative displacement between the jejunal tube 3 and the flexible insertion tube 5 during the insertion process, which affects the accuracy of the insertion position of the jejunal tube 3.
[0029] The elastic airbag 51 is located above the camera 13, and the air inlet 54 of the air inlet pipe 55 is located in the middle of the handle 4. The air inlet 54 of the elastic airbag 51 is connected to the air inlet pipe 55 that penetrates the flexible insertion tube 5, and the air inlet 54 is connected to the inflation device outside the catheter placement device, and the elastic airbag 51 is expanded by replenishing gas through the air inlet pipe 55. The side wall of the inflated elastic airbag 51 contacts the inner wall of the jejunal tube 3 and props it up. The setting of the elastic airbag 51 prevents the jejunal tube 3 from being damaged after it expands and props up the jejunal tube 3. The end of the flexible insertion tube 5 can be swung up and down, left and right to adjust the angle. The angle adjustment improves the accuracy of the insertion of the jejunal tube 3. The relevant structure for adjusting the angle by swinging is a structure in the prior art and is not described in detail here.
[0030] The rotating ball at the bottom of the display panel 11 is rotatably connected to the rotating groove at the top of the handle 4 , so that the angle of the display panel 11 can be adjusted, making it convenient for the user to observe the image captured by the camera 13 .
[0031] An optical fiber and a transmission signal line are provided on the periphery of the auxiliary channel 53 inside the flexible insertion tube 5. The camera 13 is connected to the image processing unit through the signal transmission line, and the image processing unit is connected to the display panel 11 through the signal transmission line. The optical fiber and the transmission signal line are located in the annular cavity between the outer wall of the auxiliary channel 53 and the inner wall of the flexible insertion tube 5. The optical fiber is connected to the light source 12, and the connection between the signal transmission line and the camera 13 and the display panel 11 are all existing technologies and will not be described in detail here. The light source 12 is used to illuminate the environment where the end of the flexible insertion tube 5 is located, and the camera 13 transmits the image of the illuminated area to the display panel 11.
[0032] The camera 13 is provided with an anti-fouling lens to avoid being contaminated during the insertion process and thus collecting unclear images.
[0033] A pH sensor 52 is also provided at the end of the flexible insertion tube 5. The pH sensor 52 detects the pH value of the environment at the end of the flexible insertion tube 5 to assist in determining whether the flexible insertion tube 5 enters the stomach or the intestine.
[0034] When in use, the jejunal tube 3 is sleeved outside the flexible insertion tube 5 until one end of the jejunal tube 3 moves to the fixed ring groove 41, the fixed ring clamp 21 is started to clamp the jejunal tube 3, and air is injected into the elastic airbag 51 at the same time to fix the other end of the flexible insertion tube 5 to the jejunal tube 3. The jejunal tube 3 and the flexible insertion tube 5 are inserted through the nose together, and the position of the jejunal tube 3 is observed through the display panel 11 until it is completed. The gas in the elastic airbag 51 is released, and the fixed ring clamp 21 is opened to withdraw the flexible insertion tube 5. The deflated elastic airbag 51 contacts the side wall of the flexible insertion tube 5, but not the inner wall of the jejunal tube 3.
[0035] Therefore, the present invention adopts a handheld bedside visualized jejunal tube placement device of the above structure, which has a simple structure. One end of the jejunal tube is fixedly connected to the handle through a fixed ring clamp, and the other end is supported and fixed by an elastic airbag, so that the two ends of the jejunal tube are fixed on the flexible insertion tube and the handle. The visual unit makes the jejunal tube insertion path visible, improves the insertion accuracy of the jejunal tube, and reduces the operation time. Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that they can still modify or replace the technical solution of the present invention with equivalents, and these modifications or equivalent replacements cannot make the modified technical solution deviate from the spirit and scope of the technical solution of the present invention.
