Description

Technical Field

[0001] This utility model relates to the field of gas sterilization equipment technology, and in particular to a sterilization device for anesthesiology. Background Technology

[0002] Disinfection of the anesthesia machine tubing is a key step in infection control after the use of the anesthesia machine. It refers to the process of thoroughly killing or removing pathogenic microorganisms from the internal and external circuits of the anesthesia machine. Clinically, high-temperature and high-pressure sterilization, chemical immersion disinfection, and fully automatic tubing disinfection machines (using ozone or hydrogen peroxide atomization) are commonly used for terminal disinfection. For example, the Chinese utility model patent disclosed in announcement number CN224126331U, "A Dual-Circuit System Anesthesia Machine and Ventilator Internal Circuit Disinfection Machine," provides suitable disinfection agents for both the anesthesia machine and ventilator through different pathways, serving two purposes in one machine. From a clinical perspective, existing disinfection equipment generally uses a silicone sleeve for direct connection to the anesthesia machine's gas circuit. During operation, the sleeve needs to be manually forced onto the circulation interface of the anesthesia machine. Because the diameter of the silicone sleeve is fixed, it can only be adapted by the elastic deformation of the material itself. In clinical practice, this connection makes the sleeve sensitive to diameter tolerances. When encountering interfaces with slightly larger diameters, installation and disassembly are very difficult. Repeated forceful pulling can easily cause premature tearing at the joint between the corrugated tube and the sleeve. Furthermore, when dealing with different brands of anesthesia machines, it is difficult to achieve a plug-and-play airtight fit with the fixed diameter. If the seal is not tight, the leakage of disinfection gas not only affects the disinfection effect of the internal circuit but also poses a significant occupational exposure risk to the operator. Utility Model Content

[0003] The purpose of this invention is to provide a disinfection device for anesthesiology, wherein basic collars are fitted at both ends of a corrugated endotracheal tube, and multiple expansion rods are arranged circumferentially on the outside of the basic collars. The multiple expansion rods are synchronously controlled by a synchronization ring, which can quickly change the fitting diameter of the sheath, improve the convenience of connecting the sheath to the circulation inlet, circulation outlet or anesthesia machine airway interface, prevent damage to the corrugated endotracheal tube caused by forceful pulling, and effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A disinfection device for anesthesiology includes an anesthesia breathing circuit disinfection machine. A circulation inlet and a circulation outlet are fixedly installed on the outer side of the anesthesia breathing circuit disinfection machine. One end of the circulation inlet and the circulation outlet are detachably connected to a connecting corrugated air tube. Both ends of the connecting corrugated air tube are fixedly installed with sleeves. A base collar is fitted on both ends of the connecting corrugated air tube near the sleeve. Multiple expansion rods and a synchronization ring are hinged to the base collar circumferentially on the outer side. The synchronization ring is slidably fitted on the multiple expansion rods.

[0005] As a further preferred embodiment of this utility model, the sheath is made of silicone, and its elastic deformation allows the diameter of the sheath to be changed when it is fitted with the circulation inlet, circulation outlet, or the structure of the anesthesia machine.

[0006] As a further preferred embodiment of this utility model, the sleeve is fixedly installed with a plurality of buckles along the outer circumference, and the buckles are used to connect to one end of the expansion rod.

[0007] As a further preferred embodiment of this utility model, two finger blocks are symmetrically fixedly installed on the outer side of the basic collar. When the synchronization ring is manually operated, the thumbs of both hands can rest on the corresponding finger blocks, making it easy to pull the synchronization ring towards the finger blocks.

[0008] As a further preferred embodiment of this utility model, a plurality of bearing seats are fixedly installed circumferentially on the outer side of the base collar away from the finger abutment block. The bearing seats are used to rotatably connect the expansion rod and provide it with a mounting fulcrum.

[0009] As a further preferred embodiment of this utility model, a limiting block is fixedly installed at one end of the expansion rod. The limiting block is used to limit the synchronous ring when it is sleeved on the expansion rod, so as to prevent the synchronous ring from detaching from the expansion rod and affecting the flaring of the sleeve. A buckle is integrally formed at the other end of the expansion rod. A fixed shaft is integrally formed inside the expansion rod near the limiting block. The fixed shaft is rotatably connected to a corresponding shaft seat. Thus, by pushing and pulling the synchronous ring, the expansion rod can make a lever movement around the fixed shaft as the rotation axis, causing the buckle to swing away from the base sleeve.

[0010] As a further preferred embodiment of this utility model, the buckle is engaged in the corresponding buckle seat. When the multiple expansion rods perform lever movements, the expansion rods use the buckle and buckle seat to widen one end of the sleeve to increase the diameter, making it easier to directly fit onto the circulation inlet, circulation outlet, or interface of the anesthesia machine.

[0011] As a further preferred embodiment of this utility model, the synchronizing ring is provided with a plurality of guide grooves adapted to the expansion rods along its inner circumferential direction, and the guide grooves are slidably connected to the corresponding expansion rods.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. In this utility model, a flaring mechanism consisting of a basic collar, an expansion rod, and a synchronization ring is respectively set at both ends of the connecting corrugated endotracheal tube. This mechanism can quickly change the fitting diameter of the cap, making it easy to quickly fit the cap onto the circulation inlet, circulation outlet, or the corresponding airway structure of the anesthesia machine. This improves the connection between the anesthesia machine and the sterilization circuit sterilizer of the anesthesia breathing circuit, while reducing the probability of damage at the connection between the connecting corrugated endotracheal tube and the cap.

[0013] 2. In this utility model, the basic collar fitted onto one end of the connecting corrugated air tube enables the rapid assembly of the entire flaring mechanism, facilitates reuse after disinfection, and reduces usage costs. Attached Figure Description

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] like Figures 1-5 As shown, the present invention provides a disinfection device for anesthesiology, including an anesthesia breathing circuit disinfection machine 1. A circulation inlet 2 and a circulation outlet 3 are fixedly installed on the outside of the anesthesia breathing circuit disinfection machine 1. One end of the circulation inlet 2 and the circulation outlet 3 are detachably connected to a connecting corrugated air tube 4. Both ends of the connecting corrugated air tube 4 are fixedly installed with a sleeve 5. A base collar 6 is fitted on both ends of the connecting corrugated air tube 4 near the sleeve 5. Multiple expansion rods 7 and a synchronization ring 8 are hinged to the base collar 6 along the outer circumferential direction. The synchronization ring 8 is slidably fitted on the multiple expansion rods 7.

[0018] Specifically, when using this anesthesiology disinfection device, first put the basic collar 6 connecting both ends of the corrugated trachea 4 into place, so that the buckle 14 integrally formed at one end of the expansion rod 7 can be inserted into the multiple buckles 9 fixedly installed on the outer circumferential side of the sleeve head 5, thus completing the installation of the expansion mechanism. Since the sleeve head 5 is made of silicone, it has good elastic deformation ability, so that the diameter of the opening can be adapted to change when it is connected to the interface. like Figures 2-5 As shown, when connecting the sterilization gas line, the operator holds one end of the connecting corrugated air tube 4 with one hand, and presses the thumbs of both hands on the two symmetrically fixed finger blocks 10 on the outside of the basic collar 6, while the other fingers pinch the synchronization ring 8 and pull it along the expansion rod 7 towards the finger blocks 10. Thus, as the synchronization ring 8 slides, it slides with the expansion rod 7 through the guide groove 15 on its inner wall, simultaneously applying pressure to the limiting block 13 fixedly installed at one end of the expansion rod 7. Since the fixed shaft 12 is rotatably connected to the corresponding shaft seat 11 fixedly installed circumferentially on the outside of the basic collar 6 away from the finger blocks 10, from... The expansion rod 7 is forced to make lever movements with the fixed shaft 12, which is integrally formed inside the expansion rod 7 near the limit block 13, as the fulcrum. At this time, the buckle 14, which is integrally formed at the other end of the expansion rod 7, swings away from the base collar 6. The buckle 14 is engaged in the corresponding buckle seat 9, so that the port of the silicone sleeve 5 can be evenly opened in the circumferential direction through the buckle seat 9, so that the diameter of the sleeve 5 is significantly enlarged. Then, by maintaining this enlarged state, the sleeve 5 can be easily fitted onto the circulation inlet 2, circulation outlet 3 of the anesthesia breathing circuit sterilizer 1 or the corresponding airway interface of the anesthesia machine. like Figures 2-5 As shown, after the sleeve is in place, release the synchronization ring 8. The sleeve 5 will automatically close and tightly hug the circulation inlet 2, circulation outlet 3, or the corresponding airway interface of the anesthesia machine due to the elastic recoil force of the silicone material. Then, in the same way as above, operate the remaining connecting corrugated air tube 4. After confirming that the connection is correct, start the disinfection program. The disinfectant is sent into the internal circuit of the anesthesia machine from the circulation outlet 3 through the connecting corrugated air tube 4. After it has fully acted, it is recovered by the circulation inlet 2. The disinfection operation is over. Pull the synchronization ring 8 towards the finger block 10 again. The expansion rod 7 swings outward again to open the sleeve 5. The sleeve 5 can then be removed from the interface. Then, disinfect the connecting corrugated air tube 4.
