Description

Technical Field

[0001] The invention belongs to the technical field of therapeutic feeding tubes, and in particular relates to an anti-entanglement wired speculum type nasointestinal tube. Background Art

[0002] A nasogastric tube is an enteral nutrition support medical device that is inserted into the nasal cavity and then passes through the pharynx, esophagus, stomach, and intestines. It is mainly used for patients who cannot take food orally normally or who have insufficient gastric motility and delayed gastric emptying.

[0003] Since it is necessary to pass through multiple parts to reach the intestine, the insertion operation of the nasointestinal tube is difficult. Currently, there are nasointestinal tubes that reduce the difficulty of operation by setting a camera at the insertion end to visualize the insertion. Publication (Announcement) No. CN222033106U discloses a nasointestinal tube for a gastroenteroscope. Since the camera and the lamp head need to be powered, an electrical housing is set at the tail end of the nasointestinal tube, that is, a mobile power supply is used. Since the nasointestinal tube needs to rotate the part of the nasointestinal tube left outside the body to adjust the direction of the insertion end when passing through certain parts during the insertion process, the electrical housing set at the tail end is large in size, which will cause the operator to be blocked by the electrical housing when turning the nasointestinal tube, and the rotation of the nasointestinal tube is not smooth, but the electrical housing is small in size and cannot meet the battery life required for the insertion operation. Therefore, this application proposes an anti-entanglement wired endoscope type nasointestinal tube. Summary of the invention

[0004] The purpose of the present invention is to provide an anti-entanglement wired endoscope type nasoenteric tube to solve the technical problem that the mobile power supply module used in the existing nasoenteric tube with a camera will affect the intubation operation.

[0005] In order to solve the above technical problems, the present invention provides an anti-entanglement wired endoscope nasointestinal tube, comprising: a main tube, whose outer wall is covered with a leather cover to form a wire harness through-hole; the wires of the camera and the wires of the lamp beads are wrapped by the leather cover to form a wire harness, and the wire harness is inserted into the wire harness through-hole from one side of the outer end of the main tube, and passes out from the outlet of the wire harness through-hole at the insertion end of the main tube, and the camera and the lamp beads are left at the insertion end of the main tube; a vertical line bracelet, on which a wire harness guide rod is provided, so that when it is put on the wrist, the wire harness outside the wire harness through-hole is inserted into the wire harness guide rod, and is tilted out of an arc segment between the base of the thumb and the wire harness guide rod.

[0006] Furthermore, the vertical line bracelet includes: a bracelet body, the top surface of which is provided with the wire harness guide rod; the wire harness guide rod is arranged obliquely and faces the hand when the bracelet body is put on the wrist; and a wire harness burying groove is opened on the wire harness guide rod.

[0007] Furthermore, an annular groove is formed on the outer wall of the end portion of the wire harness guide rod located at the bracelet body; a binding strap is sleeved in the annular groove.

[0008] Furthermore, the wiring harness includes: a main pipe fitting section, which is formed by a leather case wrapping the camera wiring harness and the lamp bead wiring harness part, and is a flat wire with a crescent-shaped cross-section; an extended section, which is formed by the leather case wrapping the camera wiring harness and the remaining part of the lamp bead wiring harness, and is a flat wire with an elliptical cross-section; the wiring harness perforation is a crescent-shaped groove; and the wiring harness buried groove is an elliptical groove.

[0009] Furthermore, a limiting hole is opened on the leather cover forming the wiring harness through hole on one side of the insertion end of the main pipe; a threading guide column is provided at the end of the main pipe fitting section passing through the wiring harness through hole on the insertion end side of the main pipe, and is suitable for passing through the limiting hole when the camera and the lamp bead are flush with the insertion end of the main pipe.

[0010] Furthermore, the walls of the wire harness guide rod on both sides of the wire harness buried groove are both arc surfaces, so that the wire harness buried groove is located in the middle depression between the two arc walls.

[0011] Furthermore, the anti-entanglement wired endoscope nasointestinal tube also includes: a sleeve, whose diameter is smaller than the main pipe so as to be inserted into the main pipe; an injection cone cap, which is sleeved on the outer end of the sleeve; and an injection cap, which is sleeved on the cone end of the injection cone cap.

[0012] The beneficial effect of the present invention is that the present invention aims to solve the technical problem that the mobile power supply module used in the existing nasogastric tube with a camera will affect the intubation operation. The anti-entanglement wired endoscope type nasogastric tube adopts a wired method to power the camera and the lamp beads and transmit image signals. The mobile power supply module and the image signal processing module will not be hung on the tail end of the main tube, and the wires of the camera and the lamp beads are wrapped by a leather case into a wiring harness, and a vertical line bracelet is provided. When using the nasogastric tube, the user needs to pinch the tail end of the main tube. When the user puts the vertical line bracelet on the wrist, the wiring harness extending from the main tube can be inserted into the wiring harness guide rod on the vertical line bracelet, so that an arc section is tilted between the base of the hand of the user pinching the tail end of the main tube and the wiring harness guide rod on the wrist. When inserting the nasogastric tube, the main tube is rotated within a few circles counterclockwise or clockwise, and the wiring harness will not react to the main tube due to the spiral to affect the intubation operation.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments of ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Example

[0022] like Figure 1 As shown, the present invention provides an anti-entanglement wired endoscope type nasointestinal tube, comprising: a main tube 100, the outer wall of which is covered with a leather cover to form a wire harness through hole 200; Figure 2 The wires of the camera 310 and the lamp beads 320 are wrapped by a leather case to form a wire harness 400, combined with Figure 3 , and the wire harness 400 passes through the wire harness through hole 200 from the outer end side of the main pipe 100, and returns to Figure 1 , pass through the outlet of the harness through hole 200 at the insertion end of the main pipe 100, and leave the camera 310 and the lamp bead 320 at the insertion end of the main pipe 100; the vertical line bracelet 500 is provided with a harness guide rod 520, so that when it is put on the wrist, the harness 400 outside the harness through hole 200 can pass through the harness guide rod 520 and tilt up to form an arc section between the base of the thumb and the harness guide rod 520.

[0023] The anti-entanglement wired endoscope nasogastric tube uses a wired method to power the camera 310 and the lamp bead 320 and transmit image signals. The tail end of the main tube 100 will not be hung with a mobile power supply module and an image signal processing module, and the wires of the camera 310 and the lamp bead 320 are wrapped by a leather case into a wire harness 400, and a vertical line bracelet 500 is provided. When using the nasogastric tube, the user needs to pinch the tail end of the main tube 100. When the user puts the vertical line bracelet 500 on the wrist, the wire harness 400 extending from the main tube 100 can be inserted into the wire harness guide rod 520 on the vertical line bracelet 500, so that an arc section is tilted between the base of the hand of the user pinching the tail end of the main tube 100 and the wire harness guide rod 520 on the wrist. When inserting the nasogastric tube, the main tube 100 is rotated counterclockwise or clockwise within a range of several circles, and the wire harness 400 will not react to the main tube 100 due to the spiral to affect the intubation operation.

[0024] like Figure 4 As shown, the vertical line bracelet 500 may include: a bracelet body 510, the top surface of which is provided with the harness guide rod 520; the harness guide rod 520 is inclined and faces the hand when the bracelet body 510 is put on the wrist; and the harness guide rod 520 is provided with a harness buried groove 521. When using the present anti-entanglement wired endoscope nasointestinal tube, taking the right hand as the main hand, the thumb and index finger of the right hand pinch the tail end of the main tube 100, and then the bracelet body 510 is worn on the wrist of the right hand with the left hand, and the harness guide rod 520 faces the right hand, and then the harness 400 extending from the main tube 100 is buried in the harness buried groove 521 with the left hand, so that an arc section is tilted between the right hand's base and the harness guide rod 520 on the wrist, and when inserting the nasointestinal tube, the main tube 100 is rotated counterclockwise or clockwise within a few circles, and the harness 400 will not react to the main tube 100 due to the spiral to affect the intubation operation.

[0025] like Figure 4 As shown, the outer wall of the wire harness guide rod 520 located at the end of the wristband body 510 is provided with an annular groove 522; a bandage 530 is sleeved in the annular groove 522. By providing the bandage 530, it can be ensured that during the intubation operation, the wire harness will not be lifted out of the buried groove 521 when it is lifted out of an arc, and it can always be lifted above the right hand and will not be entangled on the user's hand. When the anti-exit function of the bandage 530 is needed, it is necessary to bury the wire harness 400 in advance, and then adjust the length of the lifted arc section so that it can maintain the lift without falling.

[0026] In at least one embodiment, Figure 2As shown, the wiring harness 400 may include: a main fitting section 410, which is formed by a leather case wrapping the wiring harness of the camera 310 and the part of the wiring harness of the lamp bead 320, and is a flat wire with a crescent-shaped cross-section; an extended section 420, which is formed by a leather case wrapping the remaining part of the wiring harness of the camera 310 and the wiring harness of the lamp bead 320, and is a flat wire with an elliptical cross-section; the wiring harness perforation 200 is a crescent-shaped groove; and the wiring harness buried groove 521 is an elliptical groove. The crescent-shaped main pipe fitting section 410 and the crescent-shaped groove can make the main pipe fitting section 410 that needs to enter the body fit better with the round main pipe 100. In addition, the main pipe fitting section 410 is also relatively flat, which can reduce the impact on the turning of the main pipe 100 in the body; the elliptical protruding section 420 can be like a flat headphone wire, not easy to curl, so that the protruding arc section can be quickly converted between counterclockwise and counterclockwise winding when the main pipe 100 sometimes turns around to adjust the direction or is observed by the camera 310, instead of forming a curl that is difficult to recover due to frequent counterclockwise and clockwise winding, and failing to keep up with the rotation rhythm of the main pipe 100.

[0027] like Figure 2 and Figure 1 As shown, a limiting hole 600 is formed on the leather cover forming the harness through hole 200 on the insertion end side of the main tube 100; a threading guide column 411 is provided at the end of the main tube fitting section 410 passing through the harness through hole 200 on the insertion end side of the main tube 100, and is suitable for passing through the limiting hole 600 when the camera 310 and the lamp bead 320 are flush with the insertion end of the main tube 100. After the threading guide column 411 is provided, the main tube fitting section 410 can be passed through the harness through hole 200 by means of guide wire traction, and finally the threading guide column 411 is passed through the limiting hole 600, so that the camera 310 and the lamp bead 320 are flush with the insertion end of the main tube 100, ensuring the field of view of the camera.

[0028] like Figure 4 As shown, the rod walls of the wire harness guide rod 520 on both sides of the wire harness buried groove 521 are both arc surfaces, so that the wire harness buried groove 521 is located in the middle recess 523 between the two arc walls, so as to facilitate pressing the extended section 420 into the wire harness buried groove 521.

[0029] In at least one embodiment, the anti-entanglement wired endoscope nasointestinal tube may further include: a sleeve 700, whose diameter is smaller than the main tube 100, so as to be inserted into the main tube 100; an injection cone cap 710, which is sleeved on the outer end of the sleeve 700; and an air injection cap 720, which is sleeved on the cone end of the injection cone cap 710. After the nasointestinal tube enters the stomach, about 200ml-300ml of air can be injected into the stomach by inserting a thinner air delivery needle into the air injection cap 720, and then the air injection cap 720 is removed, and after the nasointestinal tube enters the intestine, the nutrient solution is delivered by inserting an infusion needle into the injection cone cap 710.

[0030] In summary, the present anti-entanglement wired endoscope type nasogastric tube uses a wired method to power the camera 310 and the lamp bead 320 and transmit image signals. The tail end of the main tube 100 will not be hung with a mobile power supply module and an image signal processing module, and the wires of the camera 310 and the lamp bead 320 are wrapped by a leather case into a wire harness 400, and a vertical line bracelet 500 is provided. When using the nasogastric tube, the user needs to pinch the tail end of the main tube 100. When the user puts the vertical line bracelet 500 on the wrist, the wire harness 400 extending from the main tube 100 can be inserted into the wire harness guide rod 520 on the vertical line bracelet 500, so that an arc section is tilted between the base of the hand of the user pinching the tail end of the main tube 100 and the wire harness guide rod 520 on the wrist. When inserting the nasogastric tube, the main tube 100 is rotated counterclockwise or clockwise within a few circles, and the wire harness 400 will not react to the main tube 100 due to the spiral to affect the intubation operation.
