Description

Technical Field

[0001] The utility model relates to the technical field related to pharyngeal leakage after laryngostomy surgery, in particular to a sterile drainage strip. Background Art

[0002] After laryngeal stoma surgery, pharyngeal leakage may occur, with fluid continuously seeping out of the stoma. The skin at the stoma may become red and dermatitis due to long-term irritation from the fluid. A sterile drainage strip can be used to absorb the fluid, for example:

[0003] Announcement No. CN201807069U discloses a drainage strip, which uses a parallel arrangement of latex tubes. It is not easy to cause blockage during surgery, which improves the drainage effect. In addition, since the latex tubes are connected by latex sheets, a groove structure is formed between the latex tubes, which further enhances the drainage effect. At the same time, local flushing and injection of drugs can also be performed through the latex tubes;

[0004] However, the above-mentioned drainage strip needs to be replaced after absorption, and a new drainage strip needs to be placed along the drainage hole to ensure that the drainage strip is placed correctly and fixed, so that the secretions around the pharyngeal fistula can be drained out through the drainage strip to reduce the chance of infection. Therefore, a replacement mechanism is needed to replace the drainage strip.

[0005] Therefore, we proposed that sterile drainage strips can solve the above problems well. Utility Model Content

[0006] The purpose of the utility model is to provide a sterile drainage strip to solve the problem raised in the above-mentioned background technology that the drainage strips currently on the market need to be replaced after absorption, and a new drainage strip needs to be placed along the drainage hole to ensure that the drainage strip is placed correctly and fixed, so that the secretions around the pharyngeal fistula can be drained out through the drainage strip to reduce the chance of infection. Therefore, a replacement mechanism is needed to replace the drainage strip.

[0011] As a preferred technical solution of the present application, the screw is octagonal in shape, and the other end of the screw is slidably arranged inside the bonding block, so that the screw can drive the bonding plate to slide inside the bonding block to prevent the screw from being driven to rotate by the threaded sleeve.

[0012] As a preferred technical solution of the present application, the extrusion airbag and the fitting bag are both made of elastic rubber, and the elastic force of the extrusion airbag is greater than the elastic force of the fitting bag. The other side of the fitting bag fits on one side of the limiting plate fixed on both sides of the drainage strip body, making it convenient to fix the limiting plate through the fitting bag.

[0013] As a preferred technical solution of the present application, a group of detachable air storage bags are sealed and connected to one side of the fitting block, and the other end of the air storage bag is connected to one end of the air supply pipe, the other end of the air supply pipe is branched to one end of two groups of diversion pipes, and the other end of the diversion pipe is connected to one side of the air jet through a connecting pipe. One side of the air jet is arranged on the inner side of the fitting block, so that the patient's throat can be blown to prevent dust from falling into the patient's laryngeal ostomy site when the drainage strip body is replaced, and air can be discharged.

[0014] As the preferred technical solution of the present application, the air storage bag is connected to one side of the gas supply main pipe with a group of air outlet valves, and the other side of the air storage bag is provided with an air inlet valve, which can continuously supply gas to the jet port and ensure long-term gas outlet processing.

[0017] Furthermore, since the elasticity of the fitted bag is smaller than that of the extrusion airbag, when the extrusion airbag is released, the gas inside the fitted bag can be transported into the extrusion airbag, and the limiting treatment of the limiting plate can be relaxed;

[0018] Furthermore, a drainage strip body is provided. Since a latex tube is provided on the surface of the drainage strip body and one side of the latex tube is located at the patient's skin, drainage treatment can be performed and replacement is conveniently performed through a limiting plate.

[0019] 2. An air storage bag is provided.

Therefore, a replacement mechanism is needed to replace the drainage strip. Please refer to the attached Figure 1 -Attached Figure 5, including a restraint belt 1, a group of elastic bandages 2 are sewn on the middle part of the restraint belt 1, and the other end of the restraint belt 1 is fixed on one side of a fitting block 3, and one side of the fitting block 3 is fitted on the laryngostomy position of the patient, and a drainage strip body 4 is arranged inside the fitting block 3, and the drainage strip body 4 is fitted on the laryngostomy position of the patient to absorb and drain the liquid; a replacement mechanism is arranged on one side of the fitting block 3, and the drainage strip body 4 arranged inside the fitting block 3 can be replaced by the setting of the replacement mechanism, so that the liquid of pharyngeal leakage caused by the laryngostomy of the patient can be absorbed. The replacement mechanism includes a rotating block 6 that is rotatably arranged on one side of the bonding block 3, and one end of the rotating block 6 is fixed on one side of the threaded sleeve 7, and the inner position of the threaded sleeve 7 is threadedly connected to the outer side of the screw 8. In addition, the end of the screw 8 is fixed on one side of the bonding plate 9, and the other end of the bonding plate 9 is bonded to one side of the extrusion airbag 10. The other end of the extrusion airbag 10 is connected to one side of the bonding capsule 11 through a hose, so that the drainage strip body 4 is replaced by the replacement mechanism. The screw 8 is octagonal in shape, and the other end of the screw 8 is slidably arranged inside the bonding block 3, so that the screw 8 can drive the bonding plate 9 to slide inside the bonding block 3. The extrusion airbag 10 and the bonding capsule 11 are both elastic rubber settings, and the elastic force of the extrusion airbag 10 is greater than the elastic force of the bonding capsule 11. The other side of the bonding capsule 11 is bonded to one side of the limit plate 5 fixed at the two sides of the drainage strip body 4.
