Abstract
Description
Technical Field
[0001] This utility model relates to the field of negative pressure drainage technology, and in particular to a thyroid drainage device. Background Technology
[0002] The thyroid gland is located in a closed space within the deep fascia of the neck, inevitably resulting in a large wound during open surgery. Postoperatively, due to the loose nature of the neck tissues and the inability to apply pressure bandages, significant bleeding and exudation often occur. If these exudates are not properly managed, they will continue to accumulate in the closed space, not only hindering wound healing but, more seriously, potentially compressing the trachea and causing respiratory distress, thus endangering the patient's safety.
[0003] After a drainage tube is inserted, medical staff must check for blood clots in the drainage fluid during the procedure. If a blood clot is found blocking the tube, an alcohol wipe should be placed over the tube, and the area should be pinched between the thumb and forefinger. The wipe should then be slid along the tube to force the fluid and blood clot into the drainage bulb. This process needs to be repeated. However, the tube may loosen during this process, and the alcohol wipe may also fall off as it slides back and forth across the tube. In such cases, medical staff must replace the alcohol wipe to ensure disinfection and prevent cross-infection, and then repeat the procedure.
[0004] These problems not only disrupt the flow of medical staff's operations and affect their efficiency, but also increase the consumption of medical consumables. Furthermore, maintaining this pinching motion for extended periods can cause hand fatigue for medical staff. Utility Model Content
[0005] In view of the above-mentioned problems in the prior art, this utility model is proposed.
[0006] The purpose of this invention is to provide a thyroid drainage device that addresses the common problems encountered by medical staff during drainage procedures, such as the tube easily slipping from their hands and alcohol wipes falling off, requiring frequent readjustment and replacement of the wipes. This not only affects the continuity and efficiency of the procedure and increases the consumption of medical consumables, but also causes hand fatigue due to the repetitive squeezing motion.
[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a thyroid drainage device, which includes a drainage unit, including a negative pressure bottle, a drainage tube and a drain tube disposed at the opening of the negative pressure bottle, and a plug disposed at the opening of the drain tube;
[0008] The dredging unit includes a fixed tube sleeved on the outer wall of the drainage tube, a squeezing sleeve disposed on one side of the fixed tube, and a trigger tube sleeved on the outer wall of the squeezing sleeve.
[0009] In a preferred embodiment of the thyroid drainage device of this utility model, the fixing tube includes a locking groove disposed on its outer wall and a transition surface disposed on one side of the locking groove.
[0010] As a preferred embodiment of the thyroid drainage device of this utility model, the compression sleeve includes a sleeve body, limiting pieces disposed at both ends of the sleeve body, a positioning tube disposed on the end face of one of the limiting pieces, a pair of folding strips disposed on the end face of the other limiting piece, and rollers disposed on the surface of the folding strips.
[0011] As a preferred embodiment of the thyroid drainage device of this utility model, the trigger tube includes a pair of push rods disposed at its end face, a pair of locking rods disposed at the other end face of the trigger tube, and pressing rods disposed on both sides of the trigger tube.
[0012] In a preferred embodiment of the thyroid drainage device of this utility model, the locking rod includes a locking hook disposed at its end and an inclined surface disposed on one side of the locking hook.
[0013] As a preferred embodiment of the thyroid drainage device of this utility model, it further includes a spring disposed on one side of the trigger tube.
[0014] The beneficial effects of this thyroid drainage device are as follows: when medical staff perform drainage operations, the operating hand no longer needs to pinch the drainage tube, reducing the risk of occupational exposure. In addition, the trigger tube is not easy to fall off after being wrapped with an alcohol wipe, which can ensure the continuity of the operation process, improve the efficiency of blood clot removal, and reduce the consumption of medical consumables. Moreover, changing the action from pinching to lifting can avoid hand fatigue of medical staff. Attached Figure Description

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0022] Secondly, the term "an 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 phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.
[0023] Example 1
[0024] Reference Figure 1 This is the first embodiment of the present invention. This embodiment provides a thyroid drainage device, including a drainage unit 1, including a negative pressure bottle 11, a drainage tube 12 and a drain tube 13 disposed at the opening of the negative pressure bottle 11, and a plug 14 disposed at the opening of the drain tube 13.
[0025] The dredging unit 2 includes a fixed pipe 21 sleeved on the outer wall of the drainage pipe 12, a squeezing sleeve 22 disposed on one side of the fixed pipe 21, and a trigger pipe 23 sleeved on the outer wall of the squeezing sleeve 22.
[0026] Furthermore, the fixing tube 21 includes a locking groove 211 disposed on its outer wall and a transition surface 212 disposed on one side of the locking groove 211.
[0027] Furthermore, the extrusion sleeve 22 includes a sleeve body 221, limiting pieces 222 disposed at both ends of the sleeve body 221, a positioning tube 223 disposed on the end face of one of the limiting pieces 222, a pair of folding strips 224 disposed on the end face of the other limiting piece 222, and rollers 225 disposed on the surface of the folding strips 224.
[0028] Furthermore, the trigger tube 23 includes a pair of push rods 231 disposed on its end face, a pair of locking rods 232 disposed on the other end face of the trigger tube 23, and pressing rods 233 disposed on both sides of the trigger tube 23.
[0029] Furthermore, the locking lever 232 includes a locking hook 2321 disposed at its end, and an inclined surface 2322 disposed on one side of the locking hook 2321.
[0030] Furthermore, it also includes a spring 24 disposed on one side of the trigger tube 23.
[0031] It should be noted that the negative pressure bottle 11 is the drainage bulb. Both the drainage tube 12 and the drain tube 13 are inserted into the negative pressure bottle 11 through soft stoppers. The other end of the drainage tube 12 is inserted into the affected area where fluid has accumulated, while the opening of the drain tube 13 is sealed with a removable plug 14. When medical staff perform drainage, they need to open the plug 14, then flatten the negative pressure bottle 11, and then insert the plug 14 again. This causes the negative pressure bottle 11 to generate negative pressure upon rebound, drawing the fluid from the affected area through the drainage tube 12 into the negative pressure bottle 11. Finally, the plug 14 is opened again to drain the fluid. It should be noted that the fluid stored in the negative pressure bottle 11 should generally not exceed half its capacity.
[0032] Without active drainage, the fluid will flow directly from the affected area into the negative pressure bottle 11.
[0033] Preferably, the fixing tube 21 is sleeved and fixed to the drainage tube 12 adjacent to the affected area. An annular locking groove 211 is provided on the outer wall of the drainage tube 12, and an arc-shaped transition surface 212 is provided on the side wall of the locking groove 211 away from the affected area.
[0034] Preferably, the compression sleeve 22 is tubular and is also fitted onto the outer wall of the drainage tube 12, located on the side of the fixing tube 21 away from the affected area. Symmetrical limiting plates 222 are fixed on the two end faces of the sleeve body 221. The limiting plates 222 are annular, and a positioning tube 223 is also fixed on the end face of the limiting plate 222 facing the fixing tube 21. In addition, two symmetrically distributed folding strips 224 are fixed on the end face of the limiting plate 222 on the other side. The folding strips 224 are open outward in a V-shape, and a roller 225 is fitted through the folding strip 224 at the inflection point of the folding strip 224.
[0035] Preferably, a pair of notches are symmetrically provided at the outer edge of the limiting piece 222 to prevent the trigger tube 23 from rotating on the extrusion sleeve 22.
[0036] Preferably, the trigger tube 23 is sleeved on the sleeve body 221, and the trigger tube 23 can move axially along the sleeve body 221. However, due to the restriction of the two limiting plates 222, the trigger tube 23 can only move within a limited stroke. Symmetrical push rods 231 are also fixed on both sides of the outer wall of the trigger tube 23, and medical personnel can operate the movement of the trigger tube 23 by pushing and pulling the push rods 231. Two symmetrically distributed locking rods 232 are also fixed on the side of the trigger tube 23 facing the fixed tube 21. A locking hook 2321 is fixed at the end of each locking rod 232. The two locking hooks 2321 are symmetrically distributed. In addition, a bevel 2322 is provided at the outermost edge of the locking hook 2321.
[0037] Symmetrically distributed push rods 231 are fixed on the side end of the trigger tube 23 facing the folding bar 224, and the ends of the push rods 231 directly point to the corresponding folding bar 224.
[0038] Preferably, both the locking rod 232 and the push rod 231 are in contact with the notch surface on the corresponding limiting piece 222, so the trigger tube 23 cannot rotate on the compression sleeve 22.
[0039] Preferably, a spring 24 is also sleeved between the end face of the trigger tube 23 facing the fixed tube 21 and the side limiting piece 222.
[0040] When the locking rod 232 extends towards the fixed tube 21 and the locking hook 2321 engages with the engaging groove 211, the spring 24 is compressed. At this time, the push rod 231 does not exert force on the corresponding folding strip 224, so the folding strip 224 will not bend. The locking hook 2321 is in contact with the transition surface 212 at this time. It should be noted that in order to ensure the spring 24 is compressed, a positioning tube 223 is needed to control the position between the sleeve body 221 and the fixed tube 21. Since the stroke of the compression sleeve 22 requires a certain distance to exert force on the folding strip 224, the push rod 231 needs to maintain a certain distance; therefore, the positioning tube 223 is needed to adjust the distance between the sleeve body 221 and the fixed tube 21.
[0041] When a blood clot appears in the drainage tube 12 and cannot fall into the negative pressure bottle 11 on its own, the staff actively pushes the trigger tube 23 into the negative pressure bottle 11. Due to the presence of the transition surface 212, the push rod 231 can be easily disengaged from the locking groove 211. Then, under the action of the spring 24, the trigger tube 23 is pushed to the limit of its stroke. At this time, the end of the push rod 231 presses the oblique part of the corresponding folding strip 224, causing the two folding strips 224 to move in opposite directions under pressure, and the drainage tube 12 is squeezed by the two rollers 225. When the medical staff pushes the pressing rod 233 along the direction of the drainage tube 12, the trigger tube 23 drives the squeezing sleeve 22 to slide. At this time, the two folding strips 224 can achieve the same effect as the index finger and thumb squeezing and sliding the drainage tube 12, which can avoid the possibility of the medical staff directly contacting the drainage tube 12. In addition, it also reduces the fatigue of the medical staff's hands from maintaining the same action for a long time.
[0042] To further reduce occupational exposure risks, alcohol wipes should be wrapped around the pressure lever 233. Meanwhile, during active drainage, the two pressure levers 233 can be hooked with the index and middle fingers to prevent the person from releasing the drainage tube 12, ensuring the continuity of the operation.
[0043] When the trigger tube 23 needs to move in the reverse direction, medical staff can use the same index and middle finger posture to lift the pressing rod 233. Since the roller 225 is in the state of squeezing the drainage tube 12, the resistance generated during the lifting process will cause the trigger tube 23 to squeeze the spring 24 in the reverse direction, so that the deformation of the folding bar 224 gradually recovers until the force of the spring 24 and the resistance of the folding bar 224 on the drainage tube 12 tend to be balanced. At this time, the trigger tube 23 together with the squeezing sleeve 22 can be lifted to the vicinity of the fixed tube 21 relatively easily.
[0044] This process is repeated until the blood clot in the drainage tube 12 is cleared.
[0045] When the positioning tube 223 contacts the fixing tube 21, the locking hook 2321 will re-hook into the locking groove 211 through the contact between the inclined surface 2322 and the outer edge of the end face of the fixing tube 21. The trigger tube 23 is locked, and the spring 24 is compressed. The folding bar 224 is no longer squeezed and fully recovers its deformation. At this time, the drainage tube 12 is also in a clear state. Waiting for the next active drainage operation.
[0046] In summary, this design eliminates the need for medical staff to pinch the drainage tube during drainage procedures, reducing the risk of occupational exposure. Furthermore, the alcohol wipes covering the trigger tube are less likely to fall off, ensuring the continuity of the procedure, improving the efficiency of blood clot removal, and reducing the consumption of medical consumables. Moreover, the change from pinching to lifting avoids hand fatigue for medical staff.
