Wherein, the nasal indwelling tube 1 is a nasogastric tube or a nasointestinal tube, the side wall of the insertion end is spaced apart with a plurality of through holes, and the concentration of lidocaine in the lubricating anesthetic is 2%-5%.

[0046] Specifically, the present invention provides a nasal indwelling tube assembly with lubricating anesthesia function, including a nasal indwelling tube 1, a lubricating anesthesia component 2, a cotton swab bag 3, a spiral pine cone type external joint 4 and a rubber plug 5. The lubricating anesthetic composed of an anesthetic and a lubricant is used to combine the lubricant and the anesthetic into one, so that the lubricating anesthetic preparation can simultaneously meet the two effects of lubrication and anesthesia, thereby reducing costs and alleviating the economic burden of patients. The lubricating anesthetic component 2 can be used to set the lubricating anesthetic on the outer wall of the insertion end of the nasal indwelling tube 1. When the nasal indwelling tube 1 is inserted When the insertion end is inserted into the patient's nasal cavity for catheterization, the lubricating anesthetic on the outer wall of the insertion end can play a local anesthetic and lubricating role on the nasal and throat mucosa, reduce the irritation of the tube to the mucosa, relieve the discomfort caused by the indwelling tube to the patient, improve comfort, and reduce the risk of diagnosis and treatment; the cotton swab package 3 includes a cotton swab packaging bag 31 and a cotton swab 32, and the cotton swab 32 is sealed inside the cotton swab packaging bag 31. During clinical use, before catheterization, the cotton swab packaging bag 31 can be opened, the cotton swab 32 can be taken out, and the cotton swab head of the cotton swab 32 soaked with anesthetic lubricant can be used to wet the catheter. The nasal cavity on the side can be used to provide local anesthesia and lubrication for the mucous membranes of the nose and throat, thereby improving the effect of anesthesia and further reducing the patient's discomfort. The end of the connecting end of the nasal indwelling tube 1 is fixed with a spiral pine cone-shaped external joint 4 with an inner diameter that increases from the insertion end to the connecting end. The outer size of the rubber plug 5 with a truncated cone-shaped structure is adapted to the inner size of the spiral pine cone-shaped external joint 4. The first external thread provided on the outer wall of the rubber plug 5 is adapted to the internal thread provided on the inner wall of the spiral pine cone-shaped external joint 4. The rubber plug 5 can be inserted into the spiral pine cone-shaped structure. The interior of the external joint 4 is threadedly connected through a first external thread and an internal thread to connect the rubber plug 5 to the spiral pine cone type external joint 4 by means of a thread, so as to seal the spiral pine cone type external joint 4 through the rubber plug 5, thereby closing the nasal indwelling tube 1. In addition, the spiral pine cone type external joint 4 is made of elastic material and has a certain elasticity. The design of the frustum of the spiral pine cone type external joint 4 and the frustum of the rubber plug 5 are sealed together, so that the inner wall of the spiral pine cone type external joint 4 can better fit with the outer wall of the rubber plug 5, thereby enhancing the connection stability and sealing.

[0047] In some possible implementations, the anesthetic is lidocaine, and the lubricant is paraffin oil. Specifically, the lubricating anesthetic can be prepared from lidocaine and paraffin oil.

[0048] Those skilled in the art will appreciate that lidocaine in lubricating anesthetics can penetrate mucous membranes and skin well, and can produce sufficient analgesic effect at the local site of medication. Paraffin oil can reduce friction in the pipeline and alleviate the patient's pain.

[0049] In some possible embodiments, the lubricating anesthetic part 2 includes: a lubricating anesthetic coating, which is coated on the outer walls around the insertion end along the length direction of the transnasal indwelling tube 1, and the lubricating anesthetic coating is prepared from the lubricating anesthetic. Specifically, the lubricating anesthetic coating can be formed by evenly coating the lubricating anesthetic on the outer walls around the insertion end; a sealing film 21, which is wrapped around the outer periphery of the lubricating anesthetic coating.

[0050] This is because the lubricating anesthetic coating made of lubricating anesthetic is coated on the outer walls around the insertion end of the transnasal indwelling tube 1 along the length direction. When the insertion end of the transnasal indwelling tube 1 is inserted from the nasal cavity for catheterization, the lubricating anesthetic on the outer wall of the insertion end can play a local anesthetic and lubricating role on the nasal and throat mucosa; the sealing film 21 is wrapped around the outer periphery of the lubricating anesthetic coating to seal and preserve the lubricating anesthetic coating of the insertion end, so that the sealing film 21 and the transnasal indwelling tube 1 with the lubricating anesthetic coated on the insertion end form an integrated structure. When catheterization is required, the sealing film 21 can be torn off for catheterization, which is easy to operate and saves operation time.

[0051] In some possible implementations, the lubricating anesthetic part 2 includes: a lubricating anesthetic bag 22, in which the lubricating anesthetic is sealed; a cotton sheet bag 23, wherein the cotton sheet bag 23 includes a cotton sheet packaging bag and cotton sheets, and the cotton sheets are sealed inside the cotton sheet packaging bag.

[0052] This is because lubricating anesthetic package 22 is sealed with lubricating anesthetic, cotton sheet package 23 includes cotton sheet packaging bag and cotton sheet, cotton sheet is sealed inside the cotton sheet packaging bag, before wetting the nasal cavity and placing the tube, the cotton sheet packaging bag can be torn open to take out the cotton sheet, and then the lubricating anesthetic package 22 can be torn open, and the lubricating anesthetic in the lubricating anesthetic package 22 can be absorbed with cotton sheet, and the lubricating anesthetic can be applied to the end of the insertion end of the nasal indwelling tube 1 to 20 cm with the cotton sheet soaked with lubricating anesthetic, and then the tube can be placed, so that the lubricating anesthetic on the outer wall of the insertion end can play a local anesthetic and lubricating role on the nasal and throat mucosa; through the split design of lubricating anesthetic package 22, cotton sheet package 23 and nasal indwelling tube 1, the lubricating anesthetic is independently packaged, and the length of the lubricating nasal indwelling tube 1 can be flexibly controlled according to actual needs, and the tube can be lubricated repeatedly.

[0053] In some possible embodiments, it also includes: a pipe fixing sticker 6, which is a double-layer structure, one layer of the double-layer structure is made of viscose material, and the other layer of the double-layer structure is made of foam sponge material. The pipe fixing sticker 6 has a strip fixing portion 61 and two wrapping portions 62, and the strip fixing portion 61 and the two wrapping portions 62 are integrally formed, and the wrapping portion 62 is a semi-arc structure. The two wrapping portions 62 are symmetrically distributed on both sides of the strip fixing portion 61 with the central axis of the strip fixing portion 61 along the length direction of the strip fixing portion 61 as the center line.

[0054] This is because the pipe fixing patch 6 has a strip fixing portion 61 and two wrapping portions 62. The two wrapping portions 62 in a semi-arc structure are symmetrically distributed on both sides of the strip fixing portion 61 with the central axis of the strip fixing portion 61 along the length direction of the strip fixing portion 61 as the center line. In clinical use, Figure 7-9 As shown, when the transnasal indwelling tube 1 is placed, the strip fixing portion 61 can be arranged in a direction perpendicular to the length of the transnasal indwelling tube 1, and the one-layer structure made of viscose material of the tube fixing patch 6 is pasted on the tube of the transnasal indwelling tube 1 near the nostril. At this time, the two wrapping portions 62 are wrapped on the tube of the transnasal indwelling tube 1, and the middle part of the strip fixing portion 61 located between the two wrapping portions 62 is wrapped on the tube of the transnasal indwelling tube 1 and then close to each other under the tube of the transnasal indwelling tube 1, so as to form a rectangular area under the tube of the transnasal indwelling tube 1 near the nostril, thereby supporting and lifting the transnasal indwelling tube 1. The two ends of the strip fixing portion 61 are respectively attached to the cheeks along the direction from the philtrum to the cheek, so as to lift and fix the transnasal indwelling tube 1 through the high-lifting platform method to avoid tube crushing, and the cross structure formed by the two wrapping portions 62 and the strip fixing portion 61 can improve the connection stability between the tube fixing patch 6 and the transnasal indwelling tube 1; in addition, during the high-lifting fixation process, a wrapping portion 62 pasted and wrapped on the tube of the transnasal indwelling tube 1 can enter the nostril with the tube. At this time, another layer of structure made of foam sponge material of the tube fixing patch 6 is close to the inner wall of the nostril, and the foam sponge can reduce the pressure of the tube on the inside of the nostril to prevent pressure sores.

[0055] In some possible embodiments, it also includes: a drainage bag 7, wherein the drainage bag includes a drainage bag body 71 and a first spiral pine cone type inner joint 72, wherein the first spiral pine cone type inner joint 72 is fixed to the end of the drainage bag body 71 and is an integral structure with the drainage bag body 71, the interior of the first spiral pine cone type inner joint 72 is connected to the interior of the drainage bag body 71, the first spiral pine cone type inner joint 72 is a truncated cone cylindrical structure, the external dimensions of the first spiral pine cone type inner joint 72 are adapted to the internal dimensions of the spiral pine cone type outer joint 4, the outer wall of the first spiral pine cone type inner joint 72 is provided with a second external thread, the second external thread is adapted to the internal thread, and the first spiral pine cone type inner joint 72 is threadedly connected to the spiral pine cone type outer joint 4 via the second external thread and the internal thread.

[0056] This is because the first spiral pine cone type internal joint 72 is fixed at the end of the drainage bag body 71, the external dimensions of the first spiral pine cone type internal joint 72 of the truncated cone cylindrical structure are adapted to the internal dimensions of the spiral pine cone type external joint 4, and the second external thread set on the outer wall of the first spiral pine cone type internal joint 72 is adapted to the internal thread of the spiral pine cone type external joint 4, the first spiral pine cone type internal joint 72 can be inserted into the interior of the spiral pine cone type external joint 4, and the second external thread is threadedly connected to the internal thread, so that the outer wall of the first spiral pine cone type internal joint 72 is threadedly connected to the inner wall of the spiral pine cone type external joint 4, and then the drainage bag body 71 is connected to the nasal indwelling tube 1, in addition, through the spiral pine cone design of the first spiral pine cone type internal joint 72 and the spiral pine cone type external joint 4, the outer wall of the first spiral pine cone type internal joint 72 and the inner wall of the spiral pine cone type external joint 4 can fit better, thereby enhancing the tightness of the connection. During use, when the catheter is placed, the connecting end of the nasal indwelling tube 1 can be connected to the drainage bag 7 for drainage. When the drainage bag 7 is not connected, the drainage bag 7 can be removed and the spiral pine cone type external joint 4 can be closed with a rubber stopper 5 to close the nasal indwelling tube 1.

[0057] In some possible implementations, the drainage bag further includes a buckle 73, and the buckle 73 is sleeved on the outside of the drainage pipe on the drainage bag body 71. The buckle 73 is used to open or close the drainage pipe, which is easy to operate.

[0058] In some possible embodiments, the buckle 73 is provided with a conducting hole and a clamping channel connected to the conducting hole, the conducting hole has a V-shaped structure on one side close to the clamping channel, the size of the clamping channel at one end close to the conducting hole decreases gradually toward the size of the other end of the clamping channel away from the conducting hole, and the buckle 73 is sleeved on the outside of the drainage pipe on the drainage bag body 71 through the conducting hole.

[0059] Those skilled in the art can understand that when the drainage pipe on the drainage bag body 71 is located at the conducting hole, the drainage pipe is opened for drainage, and when the drainage pipe is moved along the conducting hole toward the clamping channel, the drainage pipe passes through the V-shaped structure on the side of the conducting hole close to the clamping channel, and under the action of the V-shaped structure, the diameter of the drainage pipe is reduced, and then enters the clamping channel. Since the size of the clamping channel at one end close to the conducting hole decreases toward the size of the other end of the clamping channel away from the conducting hole, the diameter of the drainage pipe is further reduced, so that the drainage pipe can be closed through the clamping channel.

[0060] In some possible embodiments, it also includes: a syringe 8, the syringe 8 includes a syringe body 81 and a second spiral pine cone type internal joint 82, the second spiral pine cone type internal joint 82 is fixed to the end of the syringe body 81 and is an integral structure with the syringe body 81, the interior of the second spiral pine cone type internal joint 82 is connected with the interior of the syringe body 81, the second spiral pine cone type internal joint 82 is a truncated cone cylindrical structure, the external dimensions of the second spiral pine cone type internal joint 82 are adapted to the internal dimensions of the spiral pine cone type external joint 4, the outer wall of the second spiral pine cone type internal joint 82 is provided with a third external thread, the third external thread is adapted to the internal thread, and the second spiral pine cone type internal joint 82 is threadedly connected to the spiral pine cone type external joint 4 through the third external thread and the internal thread.

[0061] Those skilled in the art can understand that the second spiral cone-shaped internal joint 82 is fixed at the end of the syringe body 81, and the external dimensions of the second spiral cone-shaped internal joint 82 with a truncated cone cylindrical structure are adapted to the internal dimensions of the spiral cone-shaped external joint 4. The third external thread provided on the outer wall of the second spiral cone-shaped internal joint 82 is adapted to the internal thread of the spiral cone-shaped external joint 4. The second spiral cone-shaped internal joint 82 can be inserted into the interior of the spiral cone-shaped external joint 4, and the third external thread is threadedly connected to the internal thread, so that the outer wall of the second spiral cone-shaped internal joint 82 is threadedly connected to the inner wall of the spiral cone-shaped external joint 4, and then the syringe body 81 is connected to the nasal indwelling tube 1, so that (gas) liquid can be sucked or injected through the syringe 8. In addition, through the spiral pine cone design of the second spiral pine cone type inner joint 82 and the spiral pine cone type outer joint 4, the outer wall of the second spiral pine cone type inner joint 82 and the inner wall of the spiral pine cone type outer joint 4 can fit better, thereby enhancing the tightness of the connection. Moreover, the unique joint design makes it impossible for the nasal indwelling tube 1 to match the ordinary intravenous infusion device joints on the market, thereby fundamentally eliminating all kinds of adverse events caused by incorrect pipeline connection.

[0062] In some possible embodiments, it also includes: a metal guide wire 9, one end of which is detachably arranged inside the transnasal indwelling tube 1 by insertion, and the other end of the metal guide wire 9 is a truncated cone structure, and the external dimensions of the other end of the metal guide wire 9 are adapted to the internal dimensions of the spiral pine cone type external connector 4, and the outer wall of the other end of the metal guide wire 9 is provided with a fourth external thread, and the fourth external thread is adapted to the internal thread, and the other end of the metal guide wire 9 is threadedly connected to the spiral pine cone type external connector 4 through the fourth external thread and the internal thread.

[0063] This is because the nasogastric tube is longer than the nasogastric tube. By inserting one end of the metal guide wire 9 into the interior of the nasal indwelling tube 1, that is, embedding the metal guide wire 9 in the nasal indwelling tube 1, it can play a better guiding role when blindly inserting the nasal indwelling tube 1 into the intestine, thereby improving the success rate of tube placement and facilitating the use of the nasogastric tube. The outer dimensions of the other end of the metal guide wire 9 with a truncated cone structure are adapted to the inner dimensions of the spiral pine cone type external connector 4, and the fourth external thread provided on the outer wall of the other end of the metal guide wire 9 is adapted to the internal thread of the spiral pine cone type external connector 4. After one end of the metal guide wire 9 is inserted into the interior of the nasal indwelling tube 1, the fourth external thread can be threadedly connected to the internal thread to thread the outer wall of the other end of the metal guide wire 9 to the inner wall of the spiral pine cone type external connector 4 to fix the other end of the metal guide wire 9 inside the spiral pine cone type external connector 4. After the nasogastric tube is successfully implanted, the other end of the metal guide wire 9 is removed to pull out the metal guide wire 9.

[0064] In some possible implementations, the lubricating anesthetic coating has a length of 60 cm.
