Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and more specifically to an anti-leakage joint device for inserting a respiratory soft endoscope into an anesthesia catheter. Background Art

[0002] The soft endoscope is a minimally invasive and advanced technology. Its visual mirror is soft and the end can be bent. The soft endoscope is relatively long and can reach the various calyces of the kidney. When the patient is undergoing respiratory surgery during general anesthesia, in order to provide the patient with breathing conditions, a trachea needs to be inserted into the patient's respiratory tract and oxygen needs to be provided to the patient through a ventilator. If the soft endoscope is required during respiratory surgery, it needs to be placed in the pre-set trachea used to provide oxygen to the patient, so that the respiratory surgery and anesthesia operations share the same airway.

[0003] At present, in order to meet the needs of anesthesiology department to insert a soft endoscope into the trachea, a branch tube is usually led out of the trachea, the port of the branch tube is covered with an end cap, the center of the end cap is provided with an insertion hole, and the end cap is equipped with a sealing plug that can block the insertion hole. When only oxygen needs to be delivered to the patient, the sealing plug is inserted into the insertion hole to seal the trachea; when the soft endoscope needs to be inserted, the sealing plug is removed and the soft endoscope is inserted through the insertion hole. However, before the soft endoscope is inserted, the insertion hole in the open state connects the internal environment of the trachea with the external environment, and it is impossible to keep the internal environment of the trachea isolated from the external environment at all times, which easily leads to air carrying bacteria, fungi, and dust entering the trachea; in addition, in order to avoid friction damage when the soft endoscope is inserted, the inner diameter of the insertion hole is generally slightly larger than the outside of the soft endoscope. During the insertion and use of the soft endoscope, there is leakage in the oxygen supply of the ventilator, and its operating state stability is poor.

[0004] Therefore, how to research and design a leak-proof joint device for inserting anesthesia catheter with a respiratory soft endoscope is a problem that we urgently need to solve. Summary of the invention

[0005] In order to solve the problems of air leakage and oxygen supply environment pollution risks when a respiratory soft endoscope is inserted into an anesthesia trachea in the prior art, the purpose of the present invention is to provide an anti-leakage joint device for inserting a respiratory soft endoscope into an anesthesia catheter.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: A leak-proof joint device for inserting anesthesia catheters into a respiratory soft endoscope, comprising a connecting cylinder, one end of which is provided with an insertion hole having a diameter smaller than the diameter of the cavity inside the connecting cylinder;

[0007] A plurality of arc-shaped plates and sealing sheets are arranged in the connecting cylinder along its circumferential direction and are located below the insertion hole. The arc-shaped plates and the sealing sheets are arranged one by one in correspondence, and the sealing sheets are fixedly connected to the end faces of the arc-shaped plates away from the insertion hole.

[0008] The symmetrical side surfaces of the arc-shaped plate are provided with an oblique cut surface which is in the same plane as the oblique side surface corresponding to the sealing sheet, and the oblique cut surface is smoothly connected to the oblique side surface corresponding to the sealing sheet;

[0009] Adjacent arc-shaped plates are rotatably connected via a rotating shaft, and the rotating shaft is arranged along the oblique surface away from the edge line of the corresponding oblique side surface and inclined downward to point to the center of the arc-shaped plate;

[0010] The end of the rotating shaft located outside the arc-shaped plate is rotatably connected to a supporting shaft, and the supporting shaft and the rotating shaft can rotate relatively in a symmetric plane between corresponding adjacent arc-shaped plates;

[0011] The inner wall of the connecting cylinder is provided with a sealing ring platform, and the supporting shaft is fixedly connected to the sealing ring platform;

[0012] When multiple sealing sheets are enclosed to form a sealing layer, the arc plate is sealed against the sealing ring; when multiple arc plates are enclosed to form a sealing cylinder, the centers of the multiple sealing sheets are open, and the top of the sealing cylinder is in sealing contact with the inner top wall of the connecting cylinder.

[0013] By adopting the above technical scheme, the connecting cylinder is connected to the tracheal branch pipe port. When the soft endoscope has not passed through the connecting cylinder, the sealing layer formed by the multiple sealing sheets and the arc plate and the sealing ring are fitted together to seal the internal cavity of the connecting cylinder; when the soft endoscope continues to extend through the insertion hole, the soft endoscope simultaneously applies pressure to the arc plate and the sealing sheet, so that adjacent arc plates rotate relative to each other around the rotating axis and tend to close together. At the same time, the rotating axis and the corresponding supporting axis rotate relative to each other to realize the closing of multiple arc plates to form a sealing cylinder, the soft endoscope is fitted with the inner wall of the sealing cylinder, and the top end of the sealing cylinder is in sealing contact with the inner top wall of the connecting cylinder, so as to realize the sealing between the connecting cylinder and the soft endoscope; after the soft endoscope passes through the sealing sheet, the sealing sheet is in contact with the side of the soft endoscope; so that the entire process of the joint device is in a sealed state, which ensures the stability of oxygen delivery and reduces the risk of infection in the oxygen supply environment.

[0014] The present invention is further configured as follows: the inner wall of the sealing ring platform is provided with an arc-shaped concave surface and a notch plane, and the notch plane is located between adjacent arc-shaped concave surfaces; the arc-shaped concave surface is for the outer wall of the arc-shaped plate to fit, and the notch plane is used to block the V-shaped notch formed when the adjacent arc-shaped plates are in an open state.

[0015] By adopting the above technical solution, when the arc plate fits with the arc concave surface, the notch plane seals the corresponding V-shaped notch, preventing the arc plate from rotating relative to the sealing ring when the connection cylinder is sealed.

[0016] The present invention is further configured as follows: a support hole for inserting a support shaft is provided in the arc-shaped concave surface.

[0017] By adopting the above technical solution, the support shaft is plugged into the support hole, making the installation and disassembly operations of the arc plate convenient.

[0018] The present invention is further configured such that: the outer wall of the arc-shaped plate and the arc-shaped concave surface are connected by an elastic rope.

[0019] By adopting the above technical solution, when a plurality of arc-shaped plates form a sealing tube, the elastic rope is in a stretched state, so that the arc-shaped plate can automatically return to a state of being in contact with the arc-shaped concave surface, and can be reused.

[0020] The present invention is further configured such that: the inner edge corners of the end surface of the arc-shaped plate away from the sealing sheet are symmetrically provided with triangular cut surfaces.

[0021] By adopting the above technical solution, friction loss between the arc plate and the top wall of the connecting cylinder can be avoided during the position change process.

[0022] The present invention is further configured as follows: the sealing sheet is made of elastic rubber and is in a concave fan shape.

[0023] By adopting the above technical solution, the concave fan shape enables the sealing sheet to automatically return to its initial state after being unfolded.

[0024] The present invention is further configured as follows: the connecting cylinder comprises a main cylinder and a cylinder cover, and the cylinder cover is threadedly matched with the main cylinder.

[0025] By adopting the above technical solution, it is convenient to install the support shaft, connect the elastic rope, etc. after opening the cylinder cover.

[0026] The present invention is further configured as follows: the connecting cylinder is connected to a cover plate via a soft belt, and an end cap of the cover plate is provided with a blocking piston which can block the insertion hole.

[0027] By adopting the above technical solution, the blocking piston is plugged into the insertion hole, which can not only further enhance the sealing performance of the connecting cylinder, but also prevent debris from passing through the insertion hole and adhering to the surface of the sealing sheet.

[0028] The present invention is further configured such that: the inner diameter of the sealing cylinder is larger than the diameter of the insertion hole.

[0029] By adopting the above technical solution, the soft lens can quickly pass through the insertion hole.

[0030] The present invention is further configured as follows: 4 to 8 arc-shaped plates and sealing sheets are provided.

[0031] By adopting the above technical solution, it is convenient to install and also makes the closing and opening operations between the arc-shaped plates convenient.

A plurality of arc plates 201 and sealing sheets 202 are provided in the connecting cylinder 101 along its own circumferential direction and are located below the insertion hole 107. The arc plates 201 and the sealing sheets 202 are arranged one by one, and the sealing sheets 202 are fixedly connected to the end surface of the arc plate 201 away from the insertion hole 107. The symmetrical side surfaces of the arc plates 201 are provided with chamfered surfaces 209 which are in the same plane as the corresponding oblique side surfaces of the sealing sheets 202, and the chamfered surfaces 209 are smoothly connected to the corresponding oblique side surfaces of the sealing sheets 202. Adjacent arc plates 201 are rotatably connected by a rotating shaft 204, and the rotating shaft 204 is arranged along the edge line of the chamfered surface 209 away from the corresponding oblique side surface and tilted downward to point to the center of the arc plate 201. The end of the rotating shaft 204 located outside the arc plate 201 is rotatably connected to the support shaft 206, and the support shaft 206 and the rotating shaft 204 can rotate relatively in the symmetric plane between the corresponding adjacent arc plates 201. A sealing ring 108 is provided on the inner wall of the connecting cylinder 101, and the support shaft 206 is fixedly connected to the sealing ring 108;

[0049] like Figure 3 and Figure 4As shown, when multiple sealing sheets 202 are enclosed to form a sealing layer, the arc plate 201 is sealed against the sealing ring 108; when multiple arc plates 201 are enclosed to form a sealing cylinder, the centers of the multiple sealing sheets 202 are in an open state, and the top end of the sealing cylinder is in sealing contact with the inner top wall of the connecting cylinder 101. The connecting cylinder 101 is connected to the tracheal branch port. When the soft endoscope does not pass through the connecting cylinder 101, the sealing layer formed by the multiple sealing sheets 202 and the arc plate 201 and the sealing ring 108 are fitted together to seal the internal cavity of the connecting cylinder 101; when the soft endoscope passes through the insertion hole 107 and continues to extend, the soft endoscope simultaneously applies pressure to the arc plate 201 and the sealing sheet 202, so that the adjacent arc plates 201 rotate relative to each other around the rotating shaft 204 and tend to close together.

When the arc-shaped plate 201 is attached to the arc-shaped concave surface 109, the notch plane 110 seals and blocks the corresponding V-shaped notch 208, and prevents the arc-shaped plate 201 from rotating relative to the sealing ring 108 when the connection cylinder 101 is sealed.

[0054] like Figure 2 and Figure 3 As shown, the sealing sheet 202 is made of elastic rubber and is in a concave fan shape. The concave fan shape enables the sealing sheet 202 to automatically return to its initial state after being unfolded.

[0055] like Figure 1 and Figure 2 As shown, the connecting cylinder 101 includes a main cylinder 102 and a cylinder cover 103, and the cylinder cover 103 is threadedly matched with the main cylinder 102.

The blocking piston 106 is plugged into the insertion hole 107, which can further enhance the sealing performance of the connecting cylinder 101 and prevent debris from passing through the insertion hole 107 and adhering to the surface of the sealing sheet 202.

At the same time, the rotating shaft 204 and the corresponding supporting shaft 206 rotate relative to each other to realize the closing of multiple arc plates 201 to form a sealing cylinder, the soft endoscope is fitted with the inner wall of the sealing cylinder, and the top end of the sealing cylinder is in sealing contact with the inner top wall of the connecting cylinder 101, so as to realize the sealing between the connecting cylinder 101 and the soft endoscope; after the soft endoscope passes through the sealing sheet 202, the sealing sheet 202 is in contact with the side of the soft endoscope; so that the whole process of the joint device is in a sealed state, which ensures the stability of oxygen delivery and reduces the risk of infection in the oxygen supply environment.
