Description

Technical Field

[0001] The invention relates to the technical field of biomedical engineering, in particular to a chest drainage component of a spherical airbag with automatic inflation and deflation functions. Background Art

[0002] Chest trauma, especially tension pneumothorax, is one of the most common and deadly surgical emergencies. Traditional chest drainage methods rely primarily on puncture needles or chest tubes with auxiliary equipment for puncture decompression or indwelling drainage. However, due to limited conditions in actual pre-hospital or field settings, traditional closed chest drainage faces the following problems:

[0003] Catheter displacement or slippage at the puncture site: During the transfer process, changes in patient position, vibration and other interferences may cause the catheter to shift or dislodge, affecting the drainage effect; Lack of a fast and effective catheter fixation mechanism: Traditional methods often require suturing or tape fixation, which is not suitable for rapid rescue or non-professional operators; Unstable puncture path: The needle track is easy to close or shift, especially after the puncture needle is removed, the puncture channel may collapse; Lack of special tools and personnel in non-hospital environments seriously restricts the efficiency and success rate of rescue.

[0004] Currently, in the existing technology, for example, Chinese patent publication number CN112121241B discloses a miniature chest drainage tube. The miniature chest drainage tube is provided with a tip section and a balloon section. The balloon section is provided with an airbag. The airbag can straighten the curved drainage tube, so that the tip section and the balloon section of the drainage tube can reach the ideal drainage position. In addition, the soft airbag reduces the irritation of the chest drainage tube to the lung tissue and chest wall, reducing the patient's discomfort. The miniaturized drainage tube can be inserted using the Seldinger puncture catheterization method, reducing trauma, and can help more pneumothorax patients reduce hospitalization time and reduce costs.

[0005] However, the above-mentioned device has obvious shortcomings when in use. When the airbag is inflated, it will squeeze the guide tube body, resulting in obstruction of the drainage medium. There is a lack of anti-extrusion mechanism. At the same time, there is a lack of coordination between the external structure of the airbag and the locking mechanism to ensure that the catheter is firmly positioned on the chest wall and avoid problems such as catheter slippage. The safety and convenience of operation need to be improved. It cannot be used in emergency scenarios in the field, pre-hospital and public emergencies. There is a lack of components for auxiliary drainage and flow control. The practicality and adaptability need to be improved.

[0006] In view of this, we proposed a chest drainage component with a spherical airbag with automatic inflation and deflation functions. Summary of the Invention

The second air vent is threaded with an air nozzle cover to provide radial support force and maintain the stability of the channel.

[0022] Compared with the prior art, the present invention provides a chest drainage assembly with a spherical airbag having automatic inflation and deflation functions, which has the following beneficial effects:

[0023] 1. The chest drainage assembly of the spherical airbag with automatic inflation and deflation functions provides radial support force, maintains channel stability, and performs better drainage. By setting a fixing component, an initial chest wall puncture channel is established using a hollow puncture needle or a guide wire sleeve before drainage, so that the head tube has smoothly entered the chest cavity along the path. During drainage, the bracket, spherical bracket, arc-shaped cover, rectangular bracket, and L-shaped bracket are placed flat so that the height of the negative pressure bottle is lower than the head tube. The height difference is used to form a drainage pressure difference. The storage plate can be used to place related parts. The conical cover and drainage holes facilitate the drainage of the medium. The long groove facilitates the placement of the air supply tube. When the micro-injection pump is started, the first air tube, the first stop valve, and the first one-way valve are used to expand the spherical airbag body. The first deflation nozzle is used to facilitate deflation. The fixing ring is used to prevent the spherical airbag body from squeezing the head tube when it is deformed, which affects the drainage of the medium. Then, radial support force can be provided, channel stability can be maintained, and drainage can be performed better.

[0024] 2. The chest drainage assembly of the spherical airbag with automatic inflation and deflation function is provided with an adsorption assembly to prevent the head tube from sliding back and forth and ensure that the drainage channel is continuously unobstructed. When the head tube and the corpus cavernosum are placed in place, the threaded column inside the circular block is rotated, so that the threaded column rotates and simultaneously pushes the first circular plate to slide inside the circular groove. At the same time, the spring rod is stretched and deformed, thereby pushing the connecting rod and the second circular plate to drive and squeeze the suction cup close to the outside of the chest cavity, so that multiple groups of suction cups are firmly adsorbed on the outside of the chest cavity. The protruding pieces facilitate pulling up the suction cups when the threaded column is reset, thereby preventing the head tube from sliding back and forth, ensuring that the drainage channel is continuously unobstructed, and the groove can accommodate part of the air supply tube.

[0025] 3. The chest drainage assembly of the spherical airbag with automatic inflation and deflation functions is provided with a control assembly to improve the overall adaptability of the drainage assembly. When the diversion pressure is insufficient, the first auxiliary stop valve on the side tube is closed and the second auxiliary stop valve is opened. Then, the piston rod is pulled inside the syringe. When the first auxiliary stop valve on the side tube is opened and the second auxiliary stop valve is closed, the piston rod is pushed inside the syringe to reset it. This reciprocating process can apply suction to the drainage point to perform auxiliary drainage. When the threaded rod is rotated inside the bracket, the movable rubber block rotates and moves axially at the same time. Through the relative distance between the movable rubber block and the fixed rubber block, the second hose can be clamped to different degrees, thereby controlling the flow rate of the medium passing through the second hose, thereby improving the overall adaptability of the drainage assembly.

[0026] 4. The chest drainage assembly of the spherical airbag with automatic inflation and deflation function is provided with an auxiliary assembly to make the overall practicality and reliability of the drainage assembly higher. When the first stop valve in the fixed assembly is closed, the elastic injection ball on the side trachea and the second trachea is squeezed and the second stop valve is opened in advance, so that the gas inside the elastic injection ball is transported to the interior of the spherical airbag body through the air supply tube, causing the latter to expand, thereby also providing radial support force and maintaining channel stability. When the second deflation nozzle is opened, the interior of the spherical airbag body can be deflated, so that when the micro-injection pump in the fixed assembly is damaged or out of power, it can still be injected, thereby improving the overall practicality and reliability.

DETAILED DESCRIPTION

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0044] In this application, the term "upper" indicates an orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. This is primarily for the purpose of better describing this application and its embodiments, and is not intended to limit the indicated devices, elements, or components to a specific orientation, or to be constructed and operated in a specific orientation. Furthermore, the term "upper" may also be used in certain circumstances to indicate a dependency or connection relationship. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0045] See also Figures 1-15 , the present invention provides a technical solution:

[0046] A chest drainage assembly with a spherical airbag having automatic inflation and deflation functions includes a drainage tube body 1. The drainage tube body 1 includes a head tube 11, a first hose 12, a Y-shaped tube 13 and a second hose 14 from the head to the tail end. The tail end of the second hose 14 is fixedly installed on the input end of a negative pressure bottle 15.

[0047] In one embodiment of the present invention, a fixing assembly 2 is provided on the drainage tube body 1, and the fixing assembly 2 includes a bracket 21. The bracket 21 is provided on the outside of the drainage tube body 1, and a spherical bracket 22 is fixedly installed at one end of the bracket 21. An arc cover 23 is clamped at one end of the spherical bracket 22, and a rectangular bracket 24 is fixedly installed at the other end of the spherical bracket 22. In addition, the negative pressure bottle 15 is adapted to the size of the internal cavity of the rectangular bracket 24, so that the negative pressure bottle 15 can be placed better when the drainage assembly body is not in use. An L-shaped bracket 25 is fixedly installed on the outer wall of the rectangular bracket 24, and the L-shaped bracket 25 is fixedly installed on the outer wall of the rectangular bracket 24. One end is connected to the other end of the bracket 21, and a storage plate 26 is fixedly installed on the arc-shaped inner wall of the spherical rack 22. In addition, three storage plates 26 are provided for storing required parts (such as parts used for puncture). The second hose 14 passes through the bracket 21, the spherical rack 22 and the storage plate 26. During drainage, the bracket 21, the spherical rack 22, the rectangular rack 24 and the L-shaped rack 25 are placed flat, so that the height of the negative pressure bottle 15 is lower than the head tube 11, and the height difference is used to form a drainage pressure difference. A conical cover 27 is fixedly installed on the head of the head tube 11, and a through hole is opened on the conical cover 27. The drainage holes 28 are penetrated. In addition, the drainage holes 28 are provided with multiple groups, and the multiple groups of drainage holes 28 are arranged with the center of the circular cross section of the conical cover 27 as the array center, and the circumferential array is evenly spaced, so that the drainage effect is better. A long groove 29 is opened inside the arc-shaped side wall of the drainage tube body 1, and an air delivery pipe 210 is arranged inside the long groove 29. A spherical airbag body 211 is fixedly installed on the outside of the head tube 11. The spherical airbag body 211 is pre-assembled in a folded state. A micro air pump 212 is fixedly installed on the outer wall of the storage plate 26. The output end of the micro air pump 212 is fixedly connected to the first air pipe 2 13, both ends of the air delivery pipe 210 are respectively fixedly installed between the inside of the side wall of the spherical airbag body 211 and the other end of the first air pipe 213. The first air pipe 213 is provided with a first stop valve 214, a first one-way valve 215 and a first air release nozzle 216. The first air release nozzle 216 is threadedly fitted with an air nozzle cover. A fixing ring 217 is fixedly installed inside the head pipe 11. In addition, six fixing rings 217 are provided, and the six fixing rings 217 are arranged in a linear array with equal spacing to prevent the spherical airbag body 211 from squeezing the head pipe 11 when it is deformed, thereby affecting the drainage of the medium.

[0048] When using this embodiment, before the drainage operation is carried out, the initial chest wall puncture channel is first constructed with the help of a hollow puncture needle or a guide wire sleeve. This step can open up a path for the head tube 11 to enter the chest cavity, ensuring that the head tube 11 can smoothly enter the chest cavity along this path (since it is a prior art, it will not be described in detail). When entering the drainage stage, the bracket 21, the spherical bracket 22, the arc cover 23, the rectangular bracket 24 and the L-shaped bracket 25 are adjusted to a lying state (such as Figure 2 As shown), at this time, the height of the negative pressure bottle 15 will be lower than the head tube 11, and the height difference between the two will form a drainage pressure difference to provide initial power for medium drainage. The storage plate 26 can be used to place the relevant parts required for puncture, which is convenient for the operator to use at any time. The conical cover 27 cooperates with the drainage hole 28 opened on it to more effectively enter the drainage area and introduce the medium into the drainage tube body 1. The long groove 29 is designed specifically for accommodating the gas supply pipe 210 to prevent the gas supply pipe 210 from being randomly placed and affecting the drainage operation. When the micro-injection pump 212 is started, the first stop valve 214 on the first air pipe 213 is opened at the same time, and the gas will flow along the first air pipe 213. The tube 213 and the air supply tube 210 enter the spherical airbag body 211, causing the spherical airbag body 211 to expand. After expansion is in place, the first stop valve 214 is closed, and the first deflation nozzle 216 can be opened at the end of drainage to realize the deflation operation of the spherical airbag body 211. The fixing ring 217 can effectively prevent the spherical airbag body 211 from squeezing the head tube 11 during the expansion and deformation process, thereby ensuring the smooth drainage of the medium in the head tube 11, and then the spherical airbag body 211 opens outward along the puncture path in the pleural cavity, forming a spherical support structure, providing radial support force, maintaining channel stability, and ensuring that the drainage work is carried out continuously and efficiently.

[0049] In one embodiment of the present invention, an adsorption assembly 3 is provided on the outside of the head tube 11, and the adsorption assembly 3 includes a circular block 31. The circular block 31 is clamped on the outside of the head tube 11, and a sponge 32 is clamped on one end of the circular block 31 close to the conical cover 27. A groove 33 is provided inside the sponge 32, and the groove 33 can accommodate part of the air delivery pipe 210. In addition, the internal thread of the circular block 31 is matched with a threaded column 34, and a circular groove 35 is provided inside the circular block 31. A first circular plate 36 is slidably provided inside the circular groove 35, and a spring rod is fixedly installed between one end of the first circular plate 36 and the inner wall of the circular block 31 37, the circular outer wall of the threaded column 34 slides in contact with the outer wall of the first circular plate 36, a connecting rod 38 is fixedly mounted on the other end of the first circular plate 36, a second circular plate 39 is fixedly mounted on the outside of the connecting rod 38, a suction cup 310 is fixedly mounted on the outside of the second circular plate 39, and a protruding piece 311 is fixedly mounted on the outside of the suction cup 310. The threaded column 34, the circular groove 35, the first circular plate 36, the spring rod 37, the connecting rod 38, the second circular plate 39, the suction cup 310 and the protruding piece 311 are arranged in three groups, and the number of spring rods 37 in a single group is set to three, so that the movement of the first circular plate 36 is more stable, which facilitates the resetting of the suction cup 310.

[0050] When this embodiment is used, after the head tube 11 and the cavernous body 32 are placed in place in the chest cavity, the operator rotates the threaded column 34 inside the circular block 31. During the rotation of the threaded column 34, its end pushes the first circular plate 36 to slide along the direction of the groove body inside the circular groove 35. At the same time, the spring rod 37 connected between the first circular plate 36 and the inner wall of the circular block 31 will be stretched and deformed to store elastic potential energy. As the first circular plate 36 moves, the connecting rod 38 connected to it will drive the second circular plate 39 to move together, thereby pushing the suction cup 310 to approach the outside of the chest cavity and squeeze the outer wall of the chest cavity. The suction cups 310 work together to firmly adhere to the outside of the chest cavity, generating a fixing force, and cooperate with the spherical airbag body 211 to achieve two-way limit fixation of the head tube 11, effectively preventing the head tube 11 from sliding back and forth during the drainage process, ensuring that the drainage channel remains unobstructed. The protrusion 311 is connected to the outside of the suction cup 310. When the threaded column 34 is reset, the operator can easily pull up the suction cup 310 by pulling the protrusion 311 to release the suction cup 310 from the outer wall of the chest cavity. The groove 33 is opened inside the cavernous body 32 to accommodate part of the air supply pipe 210 to avoid interference between the air supply pipe 210 and other components.

[0051] In one embodiment of the present invention, a control component 4 is provided on the outside of the head tube 11, and the control component 4 includes a syringe 41, a syringe 41 is fixedly mounted on the Y-shaped tube 13, a piston rod 42 is slidably fitted inside the syringe 41, a side tube 43 is fixedly mounted on one end of the syringe 41 close to the Y-shaped tube 13, a first auxiliary stop valve 44 is provided on the side tube 43, and a second auxiliary stop valve 45 is provided on the end of the Y-shaped tube 13 close to the syringe 41, which can apply suction to the drainage point to assist drainage. Furthermore, a threaded rod 46 is fitted on the internal thread of the center of the bracket 21, and a movable rubber block 47 is fixedly mounted on the end of the threaded rod 46 close to the spherical rack 22, and a fixed rubber block 48 is fixedly mounted on the inside of the bracket 21 close to the spherical rack 22. The second hose 14 passes through the fixed rubber block 48, which can control the flow rate of the medium passing through the inside of the second hose 14.

[0052] When the present embodiment is used, if the diversion pressure is insufficient during the drainage process, the first auxiliary stop valve 44 on the side tube 43 is first closed, and the second auxiliary stop valve 45 is opened. Then, the piston rod 42 is pulled outward from the inside of the syringe 41. At this time, negative pressure is formed inside the syringe 41, and suction is generated on the drainage part through the side tube 43 and the Y-shaped tube 13 to assist the drainage of the medium. Afterwards, the second auxiliary stop valve 45 is closed, and the first auxiliary stop valve 44 is opened. The piston rod 42 is pushed inside the syringe 41 to reset it, and the gas or possible medium in the syringe 41 is discharged. Such repeated operations can continuously apply suction to the drainage part, thereby enhancing the drainage pressure. Drainage effect; in addition, when the threaded rod 46 is rotated inside the bracket 21, the threaded rod 46 will drive the movable rubber block 47 to move axially while rotating. By changing the relative distance between the movable rubber block 47 and the fixed rubber block 48, the second hose 14 running through them can be clamped to different degrees. When the distance between the two is small, the clamping force on the second hose 14 is large, and the flow rate of the medium passing through the second hose 14 is reduced; when the distance between the two is large, the clamping force is small, and the flow rate of the medium passing through is increased, thereby realizing the control of the medium flow rate inside the second hose 14 and improving the adaptability of the drainage component to different drainage requirements.

[0053] In one embodiment of the present invention, an auxiliary component 5 is provided inside the spherical rack 22, and the auxiliary component 5 includes a side air pipe 51. One end of the air supply pipe 210 close to the first air pipe 213 is fixedly connected to one end of the side air pipe 51, and the other end of the side air pipe 51 is fixedly connected to one end of the second air pipe 52. An elastic injection ball 53 is fixedly installed on the other end of the second air pipe 52. A second stop valve 54, a second one-way valve 55 and a second air vent nozzle 56 are provided on the second air vent nozzle 56. The second air vent nozzle 56 is threaded with an air nozzle cover to provide radial support force and maintain the stability of the channel.

[0054] When the present embodiment is used, when the micro air injection pump 212 in the fixed component 2 is damaged or the power is exhausted and it cannot work normally, the auxiliary component 5 can be activated. At this time, the first stop valve 214 on the first air pipe 213 in the fixed component 2 is closed first to prevent gas from leaking from the air path of the fixed component 2. Then, the second stop valve 54 on the second air pipe 52 is opened. The operator squeezes the elastic injection ball 53 on the side air pipe 51 and the second air pipe 52 by hand. After the elastic injection ball 53 is pressurized, the internal gas passes through the side air pipe 51 and the second air pipe 52. The tube 52 and the air delivery pipe 210 are transported to the interior of the spherical airbag body 211, causing the spherical airbag body 211 to expand, and cooperate with the second one-way valve 55 to prevent gas backflow, which can also provide radial support force and maintain channel stability. When the spherical airbag body 211 needs to be deflated, just open the second deflation nozzle 56. The setting of the auxiliary component 5 ensures that when the injection device in the fixed component 2 fails, the inflation and deflation operations of the spherical airbag body 211 can still be achieved, thereby improving the overall practicality and reliability of the drainage component.

[0055] In summary, the drainage assembly has a simple structure, is easy to operate, and can automatically fix the drainage path in the field and during transportation, thereby effectively reducing the risks of puncture catheter displacement and slippage, and improving the stability and reliability of the drainage operation.

[0056] Among them, the micro-injection pump 212 appearing in this application document is electrically connected to its own power supply.
