Description

Technical Field

[0001] This utility model relates to the field of anesthesia technology, specifically to an inhalation anesthesia device. Background Technology

[0002] Inhalation anesthesia is a type of anesthesia that uses volatile liquids or gases to enter the body through the respiratory tract and exert an anesthetic effect from superficial to deep. It is characterized by strong anesthetic power and high controllability, and plays a dominant role in general anesthesia and in the maintenance of anesthesia.

[0003] Patent document CN221513155U discloses an inhalation anesthesia device, including an inhalation tube, an anesthesia machine, and a connecting pipe. The connecting pipe is disposed between the inhalation tube and the anesthesia machine. The inhalation tube includes a connecting fitting, an inhalation assembly, and an installation assembly. The inhalation assembly is disposed at the front end of the connecting fitting, and a buckle is provided between the inhalation assembly and the connecting fitting. The installation assembly is sleeved on the outside of the connecting fitting. The connecting fitting includes a connecting tube and a connecting port. The inhalation assembly includes an inhalation head, a sealing cap, and a suspension rope. The installation assembly includes a suspension ring, a hanging ring, a fixing block, and a limiting assembly. The limiting assembly includes a ratchet, a pawl, and a fixing post. During inhalation anesthesia, a fixing block under the ring is installed onto the suspension ring using screws. The suspension ring is fitted over the connecting tube, and the connecting tube is suspended by a rope wrapped around the ring to prevent it from falling after the patient enters anesthesia. A fixing post is installed in the fixing block, allowing the pawl to rotate stably on the outside of the fixing post. The ring is connected to a ratchet via the connecting post. By manually controlling the rotation of the connecting post on the ring, the teeth on the ratchet and the teeth on the pawl engage, and the ratchet rotates directionally along the pawl, allowing the ring's operating angle to be adjusted. This inhalation anesthesia device delivers the anesthetic through the nose and requires the connecting tube to be suspended by a rope wrapped around the ring. During actual anesthesia, the anesthesiologist typically holds a breathing mask to allow the patient to inhale the anesthetic, while constantly monitoring the patient's vital signs. If any abnormalities occur, the breathing mask can be quickly removed. Meanwhile, in order to avoid cross-contamination of bacteria, the nozzle is detachable and replaceable. However, it is inconvenient to disassemble the nozzle when replacing it, as it needs to be held by hand. During the disassembly process, bacteria on the nozzle can easily get onto the gloves, which can easily lead to cross-contamination when handling a new nozzle.

[0004] Patent document CN219614642U discloses an inhalation anesthesia device for anesthesiology, including a main body. A breathing mask and a tubing are mounted on one side of the main body, and a handle is mounted on the other side. Casters are mounted on the bottom of the main body. The breathing mask is mounted on the tubing and has a mask interface with a ring and a latch. The tubing has a tubing interface with a ring hole and a latch hole, and a limiting groove is provided on its side. Through the structure of the mask interface, tubing interface, and latch, the mask interface is inserted into the tubing interface, the ring on the mask interface is inserted into the ring hole, and the latch on the mask interface simultaneously inserts into the latch hole on the tubing interface. When using the anesthesia device, the breathing mask can be quickly changed through the mask interface and tubing interface. Used breathing masks are centrally disinfected, reducing waiting time. When the breathing mask needs to be removed, the limiting rod needs to be moved so that it slides in the limiting groove and compresses the limiting spring, releasing the locking of the buckle so that the buckle can be pulled out of the buckle hole smoothly. Therefore, the breathing mask cannot be removed quickly. Utility Model Content

[0005] The main objective of this invention is to provide an inhalation anesthesia device that allows for quick removal of the breathing mask without contact with the used mask, thus preventing cross-infection. The breathing mask of this inhalation anesthesia device is also easy to install.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0007] An inhalation anesthesia device includes an anesthesia machine. The outlet of the anesthesia machine is connected to the inlet tube of a breathing mask via a connecting component. The connecting component includes a connecting tube, one end of which is fixedly connected to the outlet of the anesthesia machine, and the other end of which is fixedly connected to a female component. A female component is detachably and fixedly sealed to the female component, and the female component is fixedly connected to the inlet tube. The female component includes a connecting ring, which is fixedly connected to the other end of the connecting tube, and has an annular groove. The female component includes a retaining ring, which is fixedly connected to the inlet tube. A sleeve is fixedly fixed to the retaining ring and is sealedly inserted into the annular groove. Multiple buckles are evenly distributed around the circumference of the retaining ring, and the buckles cooperate with a retaining ring buckle fixed to the outside of the connecting ring. A guide portion is machined on the free end of the buckle. A conical sleeve is slidably sleeved on the outside of the connecting ring. After the conical sleeve moves towards the buckle, the buckle separates from the retaining ring under the guidance of the conical sleeve, the female component disengages from the female component, and the breathing mask is removed.

[0008] Specifically, sealing rings are fixedly and sealed on both the inner and outer walls of the annular groove, and the insert is sealed to the sealing rings.

[0009] Specifically, a convex ring is fixed to the outside of the connecting ring, and a conical sleeve is located between the convex ring and the fixed ring.

[0010] Specifically, the diameter of the tapered sleeve facing the fixed ring is smaller than the diameter of the tapered sleeve near the convex ring.

[0011] Specifically, the buckle includes a vertical part, which is fixed to the outer edge of the retaining ring. A straight part perpendicular to the vertical part is fixed to the end of the vertical part away from the retaining ring. A wedge is fixed to the inner side of the straight part, with the inclined surface of the wedge facing the conical surface of the conical sleeve. The wedge is held between the fixing ring and the conical sleeve. The guide part is fixed to the end of the straight part away from the vertical part, and the end of the guide part away from the straight part is inclined towards the outside of the retaining ring.

[0012] Specifically, a fixing sleeve is concentrically fixed on the connecting ring, and the outer edge of the fixing sleeve is machined with anti-slip texture, and the connecting tube passes through the fixing sleeve.

[0013] Specifically, the connecting pipe is a corrugated flexible hose.

[0014] Specifically, an elastic element is fixed at the bottom of the annular groove, and the sleeve is inserted into the annular groove to compress the elastic element.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This device uses a conical sleeve that cooperates with the guide part on the buckle to move the conical sleeve towards the buckle. The cooperation between the conical sleeve and the buckle guide part causes multiple buckles to deform simultaneously, which facilitates the separation of the sub-component from the mother component and makes it easy to disassemble the breathing mask.

[0017] 2. By setting a fixing sleeve and adding anti-slip texture on the outside of the fixing sleeve, it is easy to grip the mother part.

[0018] 3. By setting an elastic element in the bottom of the annular groove, the elastic element can easily remove the insert from the slot after the wedge is separated from the fixed ring. This allows the breathing mask, inlet tube, and sub-component to automatically separate from the mother component. When disassembling the breathing mask, there is no need to touch the breathing mask and inlet tube, which can avoid cross-infection of bacteria. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1: Refer to Figures 1-5 As shown, an inhalation anesthesia device includes an anesthesia machine 1, the outlet of which is connected to the inlet tube 4 of a breathing mask 3 via a connecting component.

[0028] The connecting assembly includes a connecting tube 2, which is a corrugated flexible tube. One end of the connecting tube 2 is fixedly connected to the outlet of the anesthesia machine 1. The other end of the connecting tube 2 is fixedly connected to a female component, on which a female component is detachably and fixedly sealed, and the female component is fixedly connected to the inlet tube 4.

[0029] Reference Figures 2-4 As shown, the mother component includes a connecting ring 6, which is fixedly connected to the other end of the connecting pipe 2, and a ring groove 12 is provided on the connecting ring 6.

[0030] The sub-component includes a retaining ring 5, which is fixedly connected to the inlet pipe 4. A sleeve 13 is fixedly attached to the retaining ring 5 and is sealed and inserted into the annular groove 12. Specifically, sealing rings 14 are fixedly and sealedly connected to both the inner and outer walls of the annular groove 12, and the sleeve 13 is sealed and connected to the sealing rings 14.

[0031] Reference Figures 2-5 As shown, multiple snap fasteners 10 are evenly distributed and fixed on the circumference of the retaining ring 5. The snap fasteners 10 cooperate with the snap fasteners 10 of the fixing ring 11 fixed on the outside of the connecting ring 6. A guide portion 104 is machined on the free end of the snap fastener 10. A conical sleeve 9 is slidably sleeved on the outside of the connecting ring 6. A convex ring 7 is fixed on the outside of the connecting ring 6. The conical sleeve 9 is located between the convex ring 7 and the fixing ring 11. The diameter of the end of the conical sleeve 9 facing the fixing ring 11 is smaller than the diameter of the end of the conical sleeve 9 near the convex ring 7.

[0032] After the cone sleeve 9 moves toward the buckle 10, the buckle 10 separates from the fixing ring 11 under the guidance of the cone sleeve 9, the sub-part separates from the mother part, and the breathing mask 3 is removed.

[0033] The buckle 10 includes a vertical part 101, which is fixed to the outer edge of the retaining ring 5. A straight part 102 perpendicular to the vertical part 101 is fixed to the end of the vertical part 101 away from the retaining ring 5. A wedge block 103 is fixed to the inner side of the straight part 102. The inclined surface of the wedge block 103 faces the conical surface of the conical sleeve 9. The wedge block 103 is held between the fixing ring 11 and the conical sleeve 9. The guide part 104 is fixed to the end of the straight part 102 away from the vertical part 101. The end of the guide part 104 away from the straight part 102 is inclined to the outside of the retaining ring 5.

[0034] A fixing sleeve 8 is concentrically fixed on the connecting ring 6. The outer edge of the fixing sleeve 8 is processed with anti-slip texture, and the connecting tube 2 passes through the fixing sleeve 8.

[0035] When installing the breathing mask 3, insert the sleeve 13 into the annular groove 12, then bring the retaining ring 5 and the connecting ring 6 closer together, and continue inserting the sleeve 13 into the annular groove 12. When the fixing ring 11 contacts the inclined surface of the wedge 103, the latch 10 undergoes elastic deformation. When the wedge 103 is located between the fixing ring 11 and the cone sleeve 9, the latch 10 returns to its original position, and the fixing ring 11 blocks the wedge 103, preventing the retaining ring 5 from separating from the connecting ring 6. At this time, the sleeve 13 is sealed to the connecting ring 6 through the sealing ring 14, which can prevent anesthetic leakage.

[0036] When the breathing mask 3 needs to be removed after use, hold the fixing sleeve 8 and push the cone sleeve 9 towards the retaining ring 5. When the cone surface of the cone sleeve 9 contacts the guide part 104, as the cone sleeve 9 continues to move towards the fixing ring 11, the buckle 10 undergoes elastic deformation towards the outside of the fixing ring 11. After the wedge block 103 separates from the fixing ring 11, the insert sleeve 13 can be withdrawn from the ring groove 12. This device enables multiple buckles 10 to undergo elastic deformation towards the outside of the fixing ring 11 simultaneously and causes the wedge block 103 to be misaligned with the fixing ring 11, facilitating the disassembly of the sub-component and the main component.

[0037] Example 2: Based on Example 1, referring to... Figure 6 As shown, an elastic element 15 is fixed at the bottom of the annular groove 12, and the insert 13 is inserted into the annular groove 12 and then squeezes the elastic element 15.

[0038] By setting an elastic element 15 in the bottom of the annular groove 12, when the wedge block 103 is separated from the fixing ring 11, the elastic element 15 can facilitate the insertion sleeve 13 to be removed from the slot, which can facilitate the automatic separation of the breathing mask 3, the inlet tube 4 and the sub-component from the mother component. When disassembling the breathing mask 3, there is no need to touch the breathing mask 3 and the inlet tube 4, which can avoid cross-infection of bacteria.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
