Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and specifically to a breast abscess puncture and drainage device. Background Art

[0002] A breast abscess occurs when an infectious agent invades breast tissue through the nipple, causing infection of the mammary ducts and forming a suppurative tissue infection area, which is a breast abscess. Currently, the treatment of breast abscesses mostly uses incision and drainage, which is traumatic, has a slow recovery, and causes pain to patients. There are also those that use catheter drainage, where a small incision is made under local anesthesia to insert a catheter. Due to defects in the drainage device, catheter insertion is difficult, and poor drainage often occurs.

[0003] For this reason, the Chinese patent with the publication number "CN210472241U" discloses "a breast abscess puncture and drainage device". Its main structure includes a drainage tube, which is composed of a horizontal tube and a vertical tube. One end of the horizontal tube is connected to the side wall of the vertical tube. The horizontal tube is provided with a first side hole, and the vertical tube is provided with a second side hole. A flushing tube is connected to the side of the vertical tube away from the horizontal tube. One end of the horizontal tube away from the vertical tube is fixedly installed with a metal drill bit. Through the settings of the drainage tube, the horizontal tube, the vertical tube, the first side hole, the second side hole, the flushing tube, and the metal drill bit, under the guidance of B-ultrasound, the metal drill bit enters from the normal skin on one side of the abscess, passes through the abscess cavity (taking the T-arm entering the abscess cavity as the standard), and the tail line (flushing tube) is left outside the body. The metal drill bit penetrates out from the opposite side of the abscess. After adjusting the position of the drainage tube in the abscess cavity, the drainage tube is cut off at the connection of the metal drill bit, an external negative pressure drainage bottle is connected, and the tail end flushing tube is externally connected to a flushing solution. The puncture entrance automatically closes without the need for suturing.

[0004] However, during the drainage process of the above breast abscess puncture and drainage device for patients, it is unable to prevent the backflow of the aspirated pus.

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figure 1 and Figure 2 , a breast abscess puncture drainage device, including a puncture drainage tube 1 capable of docking with a breast puncture needle, a first drainage tube 2 at the liquid flow end in the puncture drainage tube 1, a second drainage tube 3 at the liquid flow end in the first drainage tube 2, and a third drainage tube 4 at the liquid flow end in the second drainage tube 3. The head end of the puncture drainage tube 1 is docked with the breast puncture needle, and then the tail end of the third drainage tube 4 is docked with the pus drainage bottle.

[0025] In order to achieve the function of slowly sucking out the pus, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4, it is necessary to set up the balloon buffer type liquid suction mechanism 5, which is internally provided with a cylindrical hollow outer shell 51 located between the first drainage tube 2 and the second drainage tube 3 and capable of realizing liquid flow, a ring-shaped hollow balloon 56 hermetically installed on the outer circumferential surface of the cylindrical hollow outer shell 51 and capable of changing the gas pressure inside it after changing its own shape, and a cylindrical elastic air film 55 embedded inside the cylindrical hollow outer shell 51 and generating an adaptive deformation under the influence of the ring-shaped hollow balloon 56. Reciprocally pressing the ring-shaped hollow balloon 56 will cause changes in the gas reserve cavity 57 and the outer region of the component activity cavity 52. The change will cause the air pressure in this region to change, thereby affecting the cylindrical elastic air film 55. The cylindrical elastic air film 55 will undergo an adaptive deformation under the action of air pressure and its own elasticity, so as to suck out the thick liquid inside the breast. During the suction process, since the cylindrical elastic air film 55 can undergo deformation and extension, the pressure formed by the cylindrical elastic air film 55 is relatively gentle, enabling the liquid to be sucked out of the breast in a slow form. During the reciprocating pressing process, it must be noted that the two balloon buffer type liquid suction mechanisms 5 need to be in a vertically inverted state. At this time, the gas inside the device will be discharged outward along the balloon buffer type liquid suction mechanism 5 located at the tail, reducing the internal pressure of the device and forming an air suction force. When the thick liquid flows into the puncture drainage tube 1 and can continuously discharge outward under the influence of its own gravity, the pressing of the ring-shaped hollow balloon 56 can be stopped. Then, the first drainage tube 2, the second drainage tube 3, the third drainage tube 4, the balloon buffer type liquid suction mechanism 5, and the two gravity type liquid one-way flow mechanisms 6 are placed in a positive hanging state, so as to realize the function of sucking out the thick liquid during slow flow.

[0026] For the specific structure of the balloon buffer type liquid suction mechanism 5, please refer to Figure 3 and Figure 4, including a cylindrical hollow outer shell 51, inside which there is a component activity chamber 52. At the top and bottom of the cylindrical hollow outer shell 51, there are respectively a first docking channel 53 and a second docking channel 54 that connect the top and bottom of the component activity chamber 52. In the middle region of the component activity chamber 52 of the cylindrical hollow outer shell 51, a cylindrical elastic air film 55 is edge-embedded. On the outer circumferential surface of the cylindrical hollow outer shell 51, a ring-shaped hollow balloon 56 is edge-mounted through two fixing rings 58, and the inner region of the ring-shaped hollow balloon 56 forms a gas reserve chamber 57. On the circumferential side surface of the cylindrical hollow outer shell 51, there is a gas flow hole 59 that connects the gas reserve chamber 57 and the component activity chamber 52. The first docking channel 53 and the second docking channel 54 are respectively docked with the first drainage tube 2 and the second drainage tube 3. The cylindrical elastic air film 55 divides the component activity chamber 52 into an outer region and an inner region. The outer region is connected to the gas flow hole 59, and the inner region is connected to the aperture regions of the first docking channel 53 and the second docking channel 54. The deformation strength of the ring-shaped hollow balloon 56 is greater than that of the cylindrical elastic air film 55.

[0027] In order to achieve the one-way flow control of gas and liquid, please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 , two gravity-type liquid one-way flow mechanisms 6 need to be set up. Inside them, there is a spherical outer shell 61 located between the puncture drainage tube 1 and the first drainage tube 2 and between the second drainage tube 3 and the third drainage tube 4 and capable of realizing liquid flow, and a hollow ball valve 65 placed inside the spherical outer shell 61, which can control the one-way downward flow of liquid under the action of its own gravity and buoyancy. When the gravity-type liquid one-way flow mechanism 6 is in an inverted state, gas can only be discharged outward through the third drainage tube 4. When the gravity-type liquid one-way flow mechanism 6 is in a positive state, under the action of the gravity and buoyancy of the ring-shaped hollow balloon 56, liquid can also only be discharged into the drainage bottle through the third drainage tube 4, thus achieving the one-way flow control of gas and liquid.

[0028] Regarding the specific structure of the gravity-type liquid one-way flow mechanism 6, please refer to Figure 5 and Figure 6, including a spherical housing 61, an outer spherical cavity 62 is provided inside the spherical housing 61, a third docking channel 63 communicating with the top region of the outer spherical cavity 62 is provided at the top of the spherical housing 61, a fourth docking channel 64 communicating with the bottom region of the outer spherical cavity 62 is provided at the bottom of the spherical housing 61, a hollow ball valve 65 capable of freely moving is placed inside the spherical housing 61 within the outer spherical cavity 62, an inner spherical cavity 66 for reducing its weight is provided inside the hollow ball valve 65, the third docking channel 63 in one of the gravity-type liquid one-way flow mechanisms 6 is docked with the tail end of the puncture drainage tube 1 and the fourth docking channel 64 at this part is docked with the head end of the first drainage tube 2, the third docking channel 63 in the other gravity-type liquid one-way flow mechanism 6 is docked with the tail end of the second drainage tube 3 and the fourth docking channel 64 at this part is docked with the head end of the third drainage tube 4, the structural radius of the outer spherical cavity 62 is greater than the structural radius of the hollow ball valve 65, and the structural radius of the hollow ball valve 65 is greater than the structural radii of the third docking channel 63 and the fourth docking channel 64.

[0029] During use, the head end of the puncture drainage tube 1 is docked with the breast puncture needle, and then the tail end of the third drainage tube 4 and the pus drainage bottle are docked. Pressing the annular hollow balloon 56 reciprocally will cause changes in the outer regions of the gas reserve cavity 57 and the component movement cavity 52. The changes will cause changes in the air pressure in the regions, thereby affecting the cylindrical elastic air film 55. The cylindrical elastic air film 55 will undergo adaptive deformation under the action of the air pressure and its own elasticity, thereby sucking out the pus inside the breast. During the sucking process, since the cylindrical elastic air film 55 can undergo deformation and extension, the pressure formed by the cylindrical elastic air film 55 is relatively gentle, enabling the liquid to be sucked out of the breast in a slow form. During the reciprocal pressing process, it must be noted that the two balloon buffer liquid sucking mechanisms 5 need to be in a vertically inverted state. At this time, the gas inside the device will be discharged outward along the balloon buffer liquid sucking mechanism 5 at the tail, reducing the internal pressure of the device and forming an air suction force. When the pus flows into the puncture drainage tube 1 and can continuously discharge outward under the influence of its own gravity, the pressing of the annular hollow balloon 56 can be stopped, and then the first drainage tube 2, the second drainage tube 3, the third drainage tube 4, the balloon buffer liquid sucking mechanism 5, and the two gravity-type liquid one-way flow mechanisms 6 are in a positive hanging state, and the liquid can only be discharged into the drainage bottle through the third drainage tube 4.

The scope of the present invention is defined by the appended claims and their equivalents.
