Description

Suture-free puncture drainage kit Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to a suture-free puncture and drainage kit. Background Art

[0002] Puncture and drainage is a common surgical procedure, typically employing a puncture trocar and drainage tube. Specifically, the puncture trocar is inserted into tissue or a body cavity to establish a channel, allowing the placement of a drainage tube to drain pus, blood, and fluids. However, this method is difficult to secure the drainage tube, which is prone to slipping against the chest wall. Consequently, careless handling can cause the tube to become dislodged, leading to failure in drainage of the effusion.

[0003] Patent CN201520500963 discloses a pleural effusion puncture drainage tube and a pleural effusion puncture drainage kit, wherein the drainage tube includes a tube body, and a retractable and inflatable balloon is provided on the side wall of the tube body. The kit includes a drainage tube, a puncture needle, and an expansion tube arranged outside the puncture needle. The expansion tube is used for inserting the tube body. Since the drainage tube is provided with a retractable and inflatable balloon, when the drainage tube is inserted into the chest cavity, it can be positioned in the chest wall by the inflated balloon, thereby preventing the drainage tube from falling off and ensuring the stable operation of the drainage tube.

[0004] Patent CN202221389535 discloses a drainage tube auxiliary device for painlessly fixing and draining leakage around a drainage tube, comprising a drainage tube and a fixing device for fixing the drainage tube to the skin around a wound; the fixing device comprises an adhesive ring, the front end face of the adhesive ring has an adhesive layer, the inner edge of the adhesive ring is connected to a fixing tube via a buffer balloon, and the fixing tube is sleeved on the outer wall of the drainage tube; the buffer balloon extends toward the rear end face of the adhesive ring, and a cavity is provided between its inner wall and the skin around the wound; a binding belt is also included; the adhesive ring and the fixing tube are connected by the buffer balloon, and when the fixing tube moves with the drainage tube, the buffer balloon can make the adhesive ring stably attached to the skin without relative movement with the skin, thereby reducing the traction between the fixing device and the skin and alleviating the patient's pain.

[0005] Patent CN201520138283 discloses a drainage tube that can be flushed and prevented from being blocked, and a device for conveniently unclogging the drainage tube. The drainage tube includes a drainage tube main body and an irrigation tube. The irrigation tube and the drainage tube main body are an integral structure and are parallel; one end of the drainage tube main body is a drainage end, and the other end is a connecting end. The drainage end is provided with a plurality of communicating holes; the irrigation tube is provided with a plurality of conducting holes connected to the drainage tube main body. The device for unclogging the drainage tube includes the above-mentioned drainage tube and an dredge. An irrigation fluid is input through the connecting port of the branch tube to flush the lesion, accelerate the healing of the patient's wound, and dilute the drainage fluid to prevent the drainage tube from being blocked. If both the drainage tube main body and the irrigation tube are blocked, the dredge rotates into the irrigation tube and inputs irrigation fluid into the irrigation tube to more effectively unblock the irrigation tube and the drainage tube main body, dilute and discharge the blockage, and the dredge has good flexibility and can pass through the bending part of the drainage tube to effectively unblock the drainage tube.

[0006] In patent CN201520500963, the balloon has only one fixed point, which has poor fixing and sealing effects, and only one narrow drainage cavity that is easily blocked.

[0007] In patent CN202221389535, the bonding can cause damage to people with sensitive skin, and when the drainage tube is removed, the tearing of the bonding may cause secondary damage to the wound;

[0008] In patent CN201520138283, it is necessary to fix the wound with sutures on the skin around the wound, which is inconvenient to fix and remove and may cause secondary damage to the wound.

[0009] Summary of the Invention

[0010] The technical problem to be solved by the present invention is to provide a suture-free puncture drainage kit to overcome the deficiencies in the above-mentioned prior art.

[0011] The technical solution of the present invention to solve the above technical problems is as follows: a suture-free puncture drainage kit, comprising: a drainage kit and a puncture kit, the drainage kit comprising: a drainage tube, and a silicone pad sleeved on the drainage tube in an interference fit manner; the drainage tube is provided with a balloon surrounding the drainage tube; the tail end of the drainage tube is provided with an inflation interface and a drainage interface, and the inflation interface is connected to the balloon; the puncture kit comprises: an expander, and a tearable sheath sleeved on the expander, the inner diameter of the tearable sheath being larger than the outer diameter of the drainage tube.

[0012] The beneficial effects of the present invention are:

[0013] First, the puncture kit penetrates the human tissue at the incision, and then the dilator is withdrawn, leaving the tearable sheath in the human body, and a channel is established with the human body through the tearable sheath;

[0014] Next, the drainage tube is inserted into the human body along the channel established by the tearable sheath. After the balloon on the drainage tube is completely inserted into the human body, the tearable sheath is pinched and slowly torn to tear the tearable sheath in half and removed from the human body.

[0015] Use an instrument to inject fluid into the balloon through the inflation port to expand the balloon. After expansion is complete, push the silicone pad toward the balloon until it is close to the skin, thus completing the fixation of the drainage tube.

[0016] Finally, connect the drainage system interface to the drainage interface at the end of the drainage tube to start drainage;

[0017] Relying on the cooperation of the balloon and silicone pad on the drainage tube, there is no need to suture and fix the drainage tube during drainage. It can not only be firmly fixed, but also seal the penetration point to isolate the human body cavity from the external environment, avoid secondary damage and reduce the risk of infection. The overall structure is simple and easy to operate. In addition, the puncture kit and drainage kit can be used together or separately according to actual conditions.

[0018] On the basis of the above technical solution, the present invention can also be improved as follows.

[0019] Furthermore, the silicone pad has a T-stage structure, with the large diameter end of the silicone pad facing the balloon.

[0020] The further beneficial effect of adopting the above is: the advantages brought by this structural form and assembly method are: when the operator pushes the silicone pad in the direction of the balloon, the resistance is small and the operation is easy, while when pushing in the opposite direction, the resistance is large, which can more effectively prevent the drainage tube from loosening after being fixed.

[0021] Furthermore, an air flow channel is defined in the wall of the drainage tube, connecting the inflation port with the balloon.

[0022] Furthermore, the drainage kit also includes: a tube clamp sleeved on the drainage tube, and a silicone pad is located between the balloon and the tube clamp.

[0023] A further beneficial effect of the above method is that before the drainage system is connected to the drainage interface at the tail end of the drainage tube, the liquid flow in the drainage tube can be blocked by a tube clamp, and after the connection, the tube clamp can be inserted to perform drainage.

[0024] Furthermore, the tail end of the drainage tube is provided with an injection interface, the wall of the drainage tube is provided with an injection channel connected to the injection interface, and a plug is provided on the injection interface.

[0025] The above further beneficial effects are: if the drainage site needs to be treated with drugs, disinfected and cleaned, or the pipeline needs to be flushed or monitored, the plug on the injection interface can be opened and connected to the relevant equipment to perform the relevant operations. For example, if flushing injection is required, the syringe can be used to connect to the injection interface for injection flushing.

[0026] Furthermore, both sides of the tearable sheath are provided with sheath handles.

[0027] A further beneficial effect of the above method is that when the tearable sheath tube needs to be torn open, the operator pinches the sheath tube handles on both sides of the tearable sheath tube and tears it, thereby facilitating the tearing open of the tearable sheath tube.

[0038] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0039] Example 1

[0040] As shown in Figures 1, 2, 3, and 4, a suture-free puncture drainage kit includes: a drainage kit 1 and a puncture kit 2. The drainage kit 1 includes: a drainage tube 110, a silicone pad 120, and a tube clamp 130. The silicone pad 120 is sleeved on the drainage tube 110 in an interference fit manner, and the tube clamp 130 is movably sleeved on the drainage tube 110.

[0041] The drainage tube 110 has a balloon 111 surrounding it, with a silicone pad 120 positioned between the balloon 111 and the tube clamp 130. The tail end of the drainage tube 110 has an inflation port 140 and a drainage port 150. The inflation port 140 is in communication with the balloon 111, allowing fluid to be injected into the balloon 111 through the inflation port 140 to expand it. The inflation port 140 has a one-way valve that allows fluid to flow from the outside into the balloon 111.

[0042] The puncture kit 2 includes: a dilator 210 and a tearable sheath 220 , wherein the tearable sheath 220 is sleeved on the dilator 210 , and the inner diameter of the tearable sheath 220 is larger than the outer diameter of the drainage tube 110 .

[0043] In clinical application:

[0044] As shown in FIG5 and FIG6, the puncture kit 2 first penetrates the human tissue at the incision, and then the dilator 210 is withdrawn, and the tearable sheath 220 is left on the human body, and a channel is established with the human body through the tearable sheath 220;

[0045] Next, the drainage tube 110 is inserted into the human body along the passage established by the tearable sheath 220. After the balloon 111 on the drainage tube 110 is completely inserted into the human body, the tearable sheath 220 is pinched and slowly torn to tear the tearable sheath 220 in half and removed from the human body, as shown in FIG7 .

[0046] A fluid is injected into the balloon 111 through the inflation port 140 with the aid of an instrument to expand the balloon 111. The instrument may be a syringe, as shown in FIG8 . After expansion is completed, the silicone pad 120 is pushed toward the balloon 111 until it is in close contact with the skin, thereby completing the fixation of the drainage tube 110. As shown in FIG9 , the drainage tube 110 only has the drainage port 150 and the inflation port 140 in the structure shown in FIG9 . This structure is merely an example structure of this embodiment.

[0047] Finally, the drainage system interface is connected to the drainage interface 150 at the tail end of the drainage tube 110, and the tube clamp 130 is opened to perform drainage.

[0048] Example 2

[0049] As shown in FIG1 , this embodiment is a further improvement on the basis of the embodiment 1, specifically as follows:

[0050] The silicone pad 120 has a T-type structure, with the large diameter end of the silicone pad 120 facing the balloon 111. The advantage of this structural form and assembly method is that when the operator pushes the silicone pad 120 toward the balloon 111, the resistance is small and the operation is easy, while when pushing in the opposite direction, the resistance is large, which can effectively prevent the drainage tube 110 from loosening after being fixed.

[0051] Example 3

[0052] As shown in FIG1 , this embodiment is a further improvement on the basis of the embodiment 1, specifically as follows:

[0053] The drainage tube 110 has an air flow channel in its wall that connects the inflation port 140 with the balloon 111 .

[0054] Example 4

[0055] As shown in FIG1 , this embodiment is a further improvement on the basis of Embodiment 1, 2 or 3, specifically as follows:

[0056] The tail end of the drainage tube 110 has an injection interface 160, and the wall of the drainage tube 110 has an injection channel connected to the injection interface 160. A plug 161 is provided on the injection interface 160. If the drainage site needs to be treated with drugs, disinfected and cleaned, or the pipeline is blocked and flushed or monitored, the plug 161 on the injection interface 160 can be opened and connected to the relevant equipment to perform related operations. For example, if flushing injection is required, a syringe can be used to connect to the injection interface 160 for injection flushing.

[0057] Example 5

[0058] As shown in FIG2 , this embodiment is a further improvement on the basis of Embodiment 1, 2, 3 or 4, specifically as follows:

[0059] There are sheath handles 221 on both sides of the tearable sheath 220. When the tearable sheath 220 needs to be torn open, the operator pinches the sheath handles 221 on both sides of the tearable sheath 220 to tear it, which makes it easier to tear open the tearable sheath 220. The sheath handles 221 are provided with steps and anti-slip grooves to prevent the sheath handles 221 from slipping off the operator's hands during the tearing process.

[0060] Although the embodiments of the present invention have been shown and described above, it will be understood that the above embodiments are illustrative and are not to be construed as limitations on the present invention. A person skilled in the art may change, modify, replace and modify the above embodiments within the scope of the present invention.
