Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, in particular to a drainage tube for monitoring abdominal cavity pressure. Background Art

[0002] During surgery, an abdominal drainage tube can drain the fluid in the abdominal cavity out of the body. Placing an abdominal drainage tube after surgery can drain bleeding and exudate from the surgical area, preventing these fluids from accumulating in the abdominal cavity and causing infection. For intra-abdominal infectious diseases, the drainage tube can drain pus, reduce inflammatory response, and help patients recover. The drainage tube used to monitor abdominal pressure is a slender medical silicone tube with side holes on the tube body and a pressure sensor near the top of the tube. When placed in the abdominal cavity, pressure acts on the sensor to change its electrical properties. The signal is converted into a digital display by connecting it to an external monitor through a wire. During surgery, abdominal pressure can be monitored in real time to avoid injury. After surgery, it can help medical staff to promptly detect abnormal abdominal pressure changes to adjust treatment. One end of the drainage tube is connected to the patient's abdominal cavity to drain the fluid in the abdominal cavity, and the other end is connected to a collection bottle to collect the drained fluid, making it convenient for medical staff to observe the amount, color and properties of the fluid. etc., in order to monitor the condition of the patient's abdominal cavity, by arranging a hand-pinched airbag at one end of the bottle, when the airbag is squeezed, the air inside it is discharged, the air pressure inside the bottle is reduced, and negative pressure is formed. The drainage tube connects the patient's abdominal cavity and the bottle. Under the action of the external atmospheric pressure, the accumulated fluid in the patient's abdominal cavity will be sucked into the bottle along the drainage tube. When the airbag in the prior art is sucking, the accumulated fluid in the patient's body will also be sucked into the airbag. The entry of the accumulated fluid into the airbag will damage the internal structure of the airbag. The airbag is made of rubber-like elastic material. The chemical substances in the accumulated fluid will corrode the airbag material, causing the airbag to be damaged, leaking, etc., and the airbag rebound speed cannot be adjusted. Because medical staff need to flexibly adjust the drainage operation according to the condition and physical condition of different patients, the airbag rebound speed is fixed, and medical staff cannot optimize the operation according to the actual drainage situation, which increases the difficulty of medical operation and reduces work efficiency. Summary of the invention

[0003] The purpose of this section is to summarize some aspects of embodiments of the present invention and briefly introduce some preferred embodiments.

DETAILED DESCRIPTION

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0035] Example 1 Reference Figure 2~Figure 14 , which is the first embodiment of the present invention, provides a drainage tube for monitoring abdominal cavity pressure. The drainage tube for monitoring abdominal cavity pressure includes a suction component 200, a drive component 300 and a main body component 100. The three can prevent the accumulated fluid from entering the airbag when the accumulated fluid is absorbed, and the airbag rebound speed can be adjusted according to actual usage.

[0036] The suction assembly 200 includes a suction piece 201, including an air pressure hood 201a, an extrusion hood 201b, a connecting pipe 201c, a valve plate 201d, a transmission pipe 201e and a blocking block 201f. The extrusion hood 201b is sleeved on the outside of the air pressure hood 201a, the connecting pipe 201c is fixed to the top of the extrusion hood 201b, the valve plate 201d is hinged inside the connecting pipe 201c, the transmission pipe 201e is inserted into one side of the extrusion hood 201b, the transmission pipe 201e is connected to the extrusion hood 201b, and the blocking block 201f is arranged in the transmission pipe 201e.

[0037] The connecting tube 201c is connected to the storage bottle 101. When the extrusion cover 201b is squeezed, the air pressure cover 201a can be driven to move, and the extrusion can generate negative air pressure. At this time, the valve plate 201d can be opened. At the same time, the gas can be blocked by the setting of the blocking block 201f to prevent the gas from leaking from the transmission tube 201e. Then, when the squeezing stops, the valve plate 201d will be closed. At this time, the drainage tube body 102 is connected to the patient to absorb the accumulated fluid in the patient's body through the rebound of the air pressure cover 201a and the extrusion cover 201b. When the two rebound, the valve plate 201d is closed, and the gas will be transmitted from the transmission tube 201e. At this time, the blocking block 201f will be squeezed to move it, and then the transmission tube 2 01e can leave space for the gas to be transmitted to the pressure hood 201a, causing the pressure hood 201a to rebound, and the accumulated fluid in the patient's body will flow into the storage bottle 101 by gravity, and the gas will be transmitted to the pressure hood 201a through the transmission tube 201e. The transmission tube 201e is connected to the drainage tube body 102. Since the transmission port of the transmission tube 201e is facing downward, the accumulated fluid will not be transmitted from the transmission tube 201e, and a sloped baffle is provided in the transmission tube 201e to prevent the accumulated fluid from flowing through the transmission tube 201e. When the pressure hood 201a returns to its original position, the transmission of gas in the transmission tube 201e will stop, and then the blocking block 201f will return to its original position to block the transmission tube 201e again for the next use.

[0038] The driving assembly 300 is arranged on the extrusion cover 201b, and includes a driving member 301, including a driving plate 301a, a connecting plate 301b, a pulley 301c, a paddle plate 301d, a movable plate 301e, a slide bar 301f, a friction plate 301g and an extrusion frame 301h. The driving plate 301a is fixed to the bottom of the extrusion cover 201b, the connecting plate 301b is fixed to one side of the driving plate 301a, and the pulley 301c is arranged on the connecting plate 301 1b side, the pulley 301c and the connecting plate 301b are rotatably connected through a bearing, the dial plate 301d is rotatably connected to one side of the pulley 301c through a rotating shaft, the movable plate 301e is hinged to one side of the driving plate 301a, the slide bar 301f is fixed to one end of the movable plate 301e, the friction plate 301g is located on one side of the slide bar 301f, the extrusion frame 301h is located on the other side of the slide bar 301f, and the slide bar 301f is slidably connected in the extrusion frame 301h.

[0039] The support frame 202b is provided with a slide groove corresponding to the pulley 301c, and the pulley 301c slides in the slide groove. When the extrusion cover 201b needs to be moved, the dial plate 301d is moved. The movement of the dial plate 301d can drive the pulley 301c to move, and the pulley 301c drives the connecting plate 301b to move. The movement of the connecting plate 301b drives the driving plate 301a to move, and at this time, the extrusion cover 201b can be driven to move and squeeze it. When the pulley 301c moves, it will rotate in the slide groove to support the connecting plate 301b. After the dial plate 301d is moved, the extrusion cover 201b will be squeezed.

[0040] Then the extrusion frame 301h is moved, and the movement of the extrusion frame 301h drives the sliding bar 301f to move. By moving the sliding bar 301f to contact the friction plate 301g, and then releasing the paddle 301d, the extrusion cover 201b returns to its original position and drives the movable plate 301e to move. The movement of the movable plate 301e drives the sliding bar 301f to move on one side of the friction plate 301g. By moving the sliding bar 301f to different degrees of fit with the friction plate 301g, the rebound speed of the extrusion cover 201b can be adjusted.

[0041] Example 2 Reference Figure 2~Figure 14 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0042] Specifically, the suction assembly 200 also includes a connecting piece 202, which is arranged on the extrusion cover 201b. A first spring 202a is arranged in the extrusion cover 201b. The first spring 202a is fixed to the bottom of the connecting pipe 201c. A support frame 202b is fixed to the top of the connecting pipe 201c. A torsion spring 202c is fixed to one side of the valve plate 201d, and the torsion spring 202c is fixed to the inner wall of the connecting pipe 201c.

[0043] When the extrusion cover 201b is pressed, an extrusion force can be applied to the first spring 202a, and the valve plate 201d can be opened at this time. The opening of the valve plate 201d can apply a twisting force to the torsion spring 202c. When the pressing on the extrusion cover 201b stops, the rotation force of the torsion spring 202c can drive the valve plate 201d to return to its original position to close it. When the extrusion cover 201b is released, the rebound force of the first spring 202a can drive the extrusion cover 201b to return to its original position. The supporting frame 202b can support the connecting pipe 201c to prevent the connecting pipe 201c from being offset, and the storage bottle 101 is located in the supporting frame 202b.

[0044] Specifically, a support tube 202d is sleeved on the outside of the transmission tube 201e, and the support tube 202d is fixed to one side of the connecting tube 201c. An inner tube 202e is fixed in the transmission tube 201e. The inner tube 202e is sleeved on the outside of the blocking block 201f. The blocking block 201f and the inner tube 202e are movably connected. A second spring 202f is fixed on one side of the blocking block 201f, and the second spring 202f is fixed to the inner wall of the inner tube 202e.

[0045] The support tube 202d is used to support the transmission tube 201e to prevent the transmission tube 201e from being offset. One end of the blocking block 201f is set as an inclined surface, and the built-in tube 202e is set as an inclined surface. When the extrusion cover 201b is pressed, the gas will enter the built-in tube 202e, and then the blocking block 201f can be used to block the gas, so that the gas is transmitted from the connecting tube 201c. When the accumulated liquid is sucked to make the gas reflux, the valve plate 201d is closed, causing the connecting tube 201c to be closed, and the gas will be transmitted from the transmission tube 201e. When transmitting from the transmission tube 201e, the blocking block 201f can be squeezed to move it. The movement of the blocking block 201f can apply a squeezing force to the second spring 202f. The blocking block 201f moves and separates from the inclined surface of the built-in tube 202e. At this time, the gas can flow from the transmission tube 201e. The transmission tube 201e is connected to the squeezing cover 201b, and the gas will be directly transmitted to the squeezing cover 201b. The accumulated liquid can drip into the storage bottle 101 due to gravity. When the squeezing cover 201b completely returns to its original position, the gas in the transmission tube 201e stops transmitting. At this time, the squeezing of the blocking block 201f can be released, and then the rebound force of the second spring 202f can drive the blocking block 201f to return to its original position for next use.

[0046] Specifically, the driving assembly 300 also includes a limit member 302, which is arranged on the dial plate 301d, a connecting block 302a is fixed to one side of the dial plate 301d, a limit block 302b is arranged in the connecting block 302a, the limit block 302b and the connecting block 302a are movably connected, a third spring 302c is fixed to one side of the limit block 302b, and the third spring 302c is fixed to the inner wall of the connecting block 302a.

[0047] When the paddle plate 301d is moved to squeeze the extrusion cover 201b, the connecting block 302a can be driven to move, and the movement of the connecting block 302a can drive the limiting block 302b to move. At this time, the connecting block 302a can be limited by the setting of the limiting block 302b to prevent the extrusion cover 201b from returning to its original position. When the extrusion cover 201b needs to be returned to its original position, the limiting block 302b is moved. At this time, the limiting of the connecting block 302a can be released by the movement of the limiting block 302b, and then the extrusion cover 201b can return to its original position. When the limiting block 302b moves, an extrusion force can be applied to the third spring 302c. When the connecting block 302a needs to be limited again, the rebound force of the third spring 302c can drive the limiting block 302b to return to its original position to limit the connecting block 302a again.

[0048] Specifically, a limiting plate 302d is provided on one side of the limiting block 302b, the limiting plate 302d is fixed to one side of the supporting frame 202b, a clamping plate 302e is fixed on the top of the limiting block 302b, an inclined panel 302f is provided on one side of the clamping plate 302e, and the inclined panel 302f is fixed to one side of the connecting block 302a.

[0049] The limit plate 302d is provided with an inclined limit groove corresponding to the limit block 302b, and the limit plate 302d is set as an inclined surface. The limit plate 302d is engaged with the limit block 302b to limit the connection block 302a in one direction. When the limit block 302b is moved to separate from the limit plate 302d, in order to prevent the rebound force of the third spring 302c from driving the limit block 302b to return to its original position, the limit block 302b can be limited by moving the clamping plate 302e to engage with the inclined panel 302f, and then the extrusion cover 201b can rebound. The clamping plate 302e has a certain elastic force. When the limit block 302b needs to return to its original position, the clamping plate 302e is separated from the inclined panel 302f by toggling, and then the limit block 302b can be driven to return to its original position by the rebound force of the third spring 302c.

[0050] Specifically, a guide block 302g is fixed on one side of the movable plate 301e, a positioning block 302h is sleeved on the outer side of the guide block 302g, the positioning block 302h is fixed to one side of the movable plate 301e, a moving bar 302i is fixed on one side of the extrusion frame 301h, a connecting sleeve 302j is sleeved on the outer side of the moving bar 302i, the moving bar 302i and the connecting sleeve 302j are movably connected, a fourth spring 302k is fixed on one side of the moving bar 302i, the fourth spring 302k is fixed to the inner wall of the connecting sleeve 302j, and the connecting sleeve 302j is fixed in the support frame 202b.

[0051] When the extrusion frame 301h moves and drives the slide bar 301f to move to contact the friction plate 301g, the moving bar 302i is driven to move. The movement of the moving bar 302i can apply a pulling force to the fourth spring 302k. When the moving bar 302i moves, it can move in the connecting sleeve 302j. At this time, the moving bar 302i can be supported to prevent the moving bar 302i from deviating when moving. When it is necessary to separate the slide bar 301f from the friction plate 301g, the fourth spring 302k rebounds. The force can drive the slide bar 301f to return to its original position, and when the movable plate 301e moves, it can drive the guide block 302g to move. A sliding groove corresponding to the guide block 302g is opened on the support frame 202b. The guide block 302g slides in the sliding groove. At this time, the movable plate 301e can be supported to prevent the movable plate 301e from shifting when moving. It is fixed to one side of the movable plate 301e through the connecting sleeve 302j, and the movable plate 301e can be supported by the setting of the connecting sleeve 302j.

[0052] Example 3 Reference Figure 1 to Figure 12 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0053] Specifically, the driving component 300 also includes a pressing member 303, which is arranged on the extrusion frame 301h. An extrusion bar 303a is arranged on one side of the extrusion frame 301h. The extrusion bar 303a is inserted into one side of the support frame 202b. The extrusion bar 303a and the support frame 202b are movably connected. A guide bar 303b is fixed on one side of the extrusion bar 303a. A guide plate 303c is sleeved on the outer side of the guide bar 303b. The guide bar 303b and the guide plate 303c are movably connected. A positioning frame 303d is sleeved on the outer side of the guide plate 303c. The guide plate 303c is slidably connected to the positioning frame 303d.

[0054] There are four groups of pressing pieces 303, all of which are set on the extrusion frame 301h. The lengths of the extrusion bars 303a are different. By moving different extrusion bars 303a to one side of the extrusion frame 301h and extruding it, the extrusion frame 301h can be moved to different positions. At this time, the sliding bar 301f and the friction plate 301g can be fitted to different degrees.

[0055] A bevel groove and a fixed groove are respectively provided on the guide plate 303c. The fixed groove is located at the bottom of the bevel groove. When the extrusion strip 303a is extruded, the guide strip 303b can be driven to move. At this time, the guide strip 303b can slide in the bevel groove to squeeze the guide plate 303c to move it. When the guide strip 303b moves to the bottom of the bevel groove and contacts the fixed groove, the guide plate 303c returns to its original position so that the fixed groove and the guide strip 303b can be engaged, thereby limiting the extrusion strip 303a.

[0056] When another extrusion strip 303a is pressed, the guide plate 303c will move again to drive the fixing groove to separate from the guide strip 303b, and the pressed extrusion strip 303a will return to its original position, and then another extrusion strip 303a will be limited by the same principle as the previous extrusion strip 303a.

[0057] There is no fixing groove on one side of the fourth extrusion strip 303a. When the fourth extrusion strip 303a is pressed, the pressed extrusion strip 303a can return to its original position. Then, when the fourth extrusion strip 303a is released, the fourth extrusion strip 303a will return to its original position, thereby completing the return of all the extrusion strips 303a to their original positions.

[0058] Specifically, an extrusion plate 303e is sleeved on the outside of the extrusion bar 303a, a fifth spring 303f is fixed to the bottom of the extrusion plate 303e, the fifth spring 303f is fixed in the positioning frame 303d, a sixth spring 303g is fixed to one side of the guide plate 303c, a support bar 303h is fixed to one end of the sixth spring 303g, the support bar 303h is fixed to the inner wall of the positioning frame 303d, the guide plate 303c is sleeved on the outside of the support bar 303h, and the guide plate 303c and the support bar 303h are movably connected.

[0059] When the extrusion bar 303a is pressed, the extrusion plate 303e can be driven to move. At this time, the movement of the extrusion plate 303e can apply an extrusion force to the fifth spring 303f. After the limit on the extrusion bar 303a is released, the rebound force of the fifth spring 303f can drive the extrusion bar 303a to return to its original position. When moving, the guide plate 303c can apply a pulling force to the sixth spring 303g, and the rebound force of the sixth spring 303g can drive the guide plate 303c to return to its original position. The support bar 303h is used to support the sixth spring 303g to prevent the sixth spring 303g from deflecting.

[0060] Specifically, it also includes a main body component 100, which is arranged on the connecting tube 201c, including a storage bottle 101 and a drainage tube body 102, the storage bottle 101 is fixed to the top of the connecting tube 201c, the drainage tube body 102 is inserted into the top of the storage bottle 101, and the transmission tube 201e is fixed to one side of the drainage tube body 102.

[0061] The drainage tube body 102 has a side hole on its body, and a pressure sensor is provided near the top inside the drainage tube body 102. When placed in the abdominal cavity, pressure acts on the sensor to change its electrical properties. The signal is converted into a digital display by connecting an external monitor through a wire. During surgery, abdominal pressure can be monitored in real time to avoid injury. After surgery, it can help medical staff to promptly detect abnormal abdominal pressure changes to adjust treatment. One end of the drainage tube body 102 is connected to the patient's abdominal cavity, and the storage bottle 101 is used to collect the drained fluid, making it convenient for medical staff to observe the amount, color and properties of the fluid, so as to monitor the condition of the patient's abdominal cavity.

[0062] Specifically, a bevel cover 103 is fixed to one end of the drainage tube body 102 .

[0063] The inclined mask 103 can be provided to drain the accumulated liquid, so that the accumulated liquid can drip into the storage bottle 101 .

[0064] When in use, first squeeze the extrusion cover 201b, and when squeezing the extrusion cover 201b, the air pressure cover 201a can be driven to move, and the extrusion can generate negative air pressure. When pressing the extrusion cover 201b, an extrusion force can be applied to the first spring 202a, and then the valve plate 201d can be opened. When the valve plate 201d is opened, a torsional force can be applied to the torsion spring 202c. At the same time, the setting of the blocking block 201f can block the gas to prevent the gas from leaking from the transmission pipe 201e. After negative air pressure is generated, in order to prevent the rebound force of the first spring 202a from driving the extrusion cover 201b to return to its original position, the connection block 302a can be limited in one direction by engaging the limit block 302b with the limit plate 302d to prevent the extrusion cover 201b from returning to its original position after the extrusion cover 201b is released. After the extrusion is completed, the pressure on the extrusion cover 201b is stopped, and the rotation force of the torsion spring 202c can drive the valve plate 201d to return to its original position to close it. At this time, the drainage tube body 102 can be connected to the patient.

[0065] At this time, it is necessary to release the limit on the extrusion cover 201b to make it rebound to absorb the accumulated fluid in the patient's body. First, according to the use situation, different extrusion bars 303a are pressed according to the rebound speed of the extrusion cover 201b. When the extrusion bar 303a is pressed, the extrusion plate 303e can be driven to move. At this time, the movement of the extrusion plate 303e can apply an extrusion force to the fifth spring 303f. When the extrusion bar 303a is squeezed, the guide bar 303b can be driven to move. At this time, the guide bar 303b can slide in the inclined groove to squeeze the guide plate 303c to make it move. The movement of the guide plate 303c can apply a pulling force to the sixth spring 303g. When the guide bar 303b moves to the bottom of the inclined groove and contacts the fixed groove, the guide plate 303c is driven to return to its original position by the rebound force of the sixth spring 303g, so that the fixed groove and the guide bar 303b can be engaged. Then the extrusion bar 303a can be limited to move to the specified position.

[0066] The extrusion bar 303a can move to squeeze the extrusion frame 301h to make it move, and the movement of the extrusion frame 301h drives the sliding bar 301f to move. By moving the sliding bar 301f to contact the friction plate 301g, the sliding bar 301f can be moved by pressing the extrusion bars 303a of different lengths. The different degrees of fit with the friction plate 301g can adjust the rebound speed of the extrusion cover 201b. After the pressing is completed, the card plate 302e can be moved to drive the limit block 302b to move. When the limit block 302b is moved to separate from the limit plate 302d, in order to prevent the rebound force of the third spring 302c from driving the limit block 302b to return to its original position, the limit block 302b can be limited by moving the card plate 302e to engage with the inclined plate 302f, and then the extrusion cover 201b can rebound.

[0067] When the extrusion cover 201b rebounds, the gas can flow into the storage bottle 101 by gravity, and the gas will be transmitted to the air pressure cover 201a through the transmission tube 201e. The transmission tube 201e is connected to the drainage tube body 102. Since the transmission port of the transmission tube 201e is downward, the accumulated liquid will not be transmitted from the transmission tube 201e. At this time, the accumulated liquid can drip into the storage bottle 101. When the accumulated liquid is sucked to make the gas flow back, the valve plate 201d is closed at this time, causing the connecting tube 201c to be closed, and the gas will be transmitted from the transmission tube 201e. When transmitting from the transmission tube 201e, the blocking block 201f can be squeezed to make it move, and the blocking block 20 1f movement can apply a squeezing force to the second spring 202f, and the blocking block 201f moves and separates from the inclined surface of the built-in tube 202e. At this time, the gas can flow from the transmission tube 201e. The transmission tube 201e is connected with the squeezing cover 201b, and the gas will be directly transmitted to the squeezing cover 201b. The accumulated liquid can drip into the storage bottle 101 due to gravity. When the squeezing cover 201b completely returns to its original position, the gas in the transmission tube 201e stops transmitting. At this time, the squeezing of the blocking block 201f can be released, and then the rebound force of the second spring 202f can drive the blocking block 201f to return to its original position, thereby completing the absorption of the accumulated liquid.

[0068] After the absorption is completed, the card plate 302e is first pushed to separate from the inclined plate 302f, and then the rebound force of the third spring 302c can drive the limit block 302b to return to its original position, and then the fourth extrusion bar 303a is pressed. When pressing the fourth extrusion bar 303a, the pressed extrusion bar 303a can return to its original position, and then the fourth extrusion bar 303a is released. At this time, the fourth extrusion bar 303a will return to its original position, thereby completing the return of all the extrusion bars 303a to their original positions.
