Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to a disposable sterile breathing circuit kit. Background Art
[0002] Sterile breathing is generally anesthesia breathing, and the anesthesia breathing circuit is one of the commonly used clinical equipment. When used clinically, the anesthesia machine mixes fresh air and anesthetics and delivers them to the patient's respiratory tract using the anesthesia breathing circuit. In order to ensure the hygiene and safety of safety equipment and prevent cross-infection of respiratory infectious diseases, the anesthesia breathing circuit usually uses disposable supplies.
[0003] An existing patent (publication number: CN 209092448 U) discloses a compact disposable anesthesia breathing circuit, which ensures the convenience of storage and use of the disposable anesthesia breathing circuit through a retractable trachea. After the buckle is connected to the interface, the flexible trachea is covered in a rigid protective layer, which is convenient for storage and ensures the cleanliness of the trachea, so that the disposable anesthesia breathing circuit has a more compact structure when stored, saves space, reduces storage costs, and improves assembly efficiency.
[0004] However, the above technical solution still has certain defects. The device is connected by a buckle, but the fixing effect is not good when used by medical staff on patients. If the trachea is accidentally stretched by external force, the buckle may be damaged and the trachea may be detached, resulting in the inability to deliver anesthetic gas to the patient's lungs, making it impossible to anesthetize them. At the same time, anesthetic gas is generally input into the patient in a quantitative manner. If the sealing effect of the tracheal connection is not good when delivering anesthetic gas, it is easy to cause anesthetic gas leakage, resulting in too little anesthetic gas being delivered, which in turn makes it impossible for the patient to be anesthetized. For this reason, a disposable sterile breathing circuit kit is proposed. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.
[0027] The following describes an embodiment of the utility model based on its overall structure.
[0028] Single-use sterile breathing circuit kit, such as Figure 1-5 As shown, it includes an integral component 100, the integral component 100 includes a telescopic bellows 110, one end of the telescopic bellows 110 is fixedly connected with a connecting component 200, and the end of the connecting component 200 away from the telescopic bellows 110 is provided with a sealing component 300;
[0029] The connecting assembly 200 includes a fixed shaft 210 fixedly connected to one end of the telescopic bellows 110, a connecting groove 211 is provided in the fixed shaft 210, a spring 220 is fixedly connected to the upper and lower ends of the connecting groove 211, a slider 230 is welded to the end of the spring 220 away from the connecting groove 211, a limit block 240 is connected to the end of the slider 230 away from the spring 220, and an insert block 250 is slidably connected to the surface of the slider 230, one side of the limit block 240 contacts the limit head 260, and a connecting rod 270 is provided at the end of the limit head 260 away from the insert block 250;
[0030] The sealing assembly 300 includes a fixed sleeve 310 attached to one side of the fixed shaft 210, and piston cylinders 320 are installed at the upper and lower ends of the inner wall of the fixed sleeve 310. The inner wall of the piston cylinder 320 is slidably connected to a piston 330, and one side of the piston 330 is fixedly connected to a piston rod 340. An extrusion spring 350 is sleeved on the surface of the piston rod 340. A connecting tube 360 is installed on the surface of the piston cylinder 320, and an inflatable sealing ring 370 is connected to the end of the connecting tube 360 away from the piston cylinder 320.
[0031] When the medical staff is installing the device, they dock the fixing sleeve 310 with the fixing shaft 210, so that the arc surface on the limit head 260 fits with the arc surface on the limit block 240. The limit block 240 is forced to drive the slider 230 to squeeze the spring 220 to move to both sides, so that the limit head is inserted into the connecting groove 211, and then the limit head 260 is connected and fixed by the limit block 240, so that the fixing shaft and the fixing sleeve 310 are quickly plugged and fixed together, which effectively improves the installation speed of the medical staff, enhances the fixing effect, and prevents the telescopic bellows 110 from being affected by external forces. The pulling force causes them to separate. At the same time, when the fixed sleeve 310 is fitted with the fixed shaft 210, the fixed shaft 210 squeezes the piston rod 340, so that the piston rod 340 drives the piston 330 to stretch and squeeze the spring 350 to move, so that the gas inside the piston cylinder 320 enters the inflatable sealing ring 370 through the connecting tube 360, and the inflatable sealing ring 370 expands, which effectively enhances the sealing effect when the fixed shaft 210 is connected to the fixed sleeve 310, and prevents leakage when the anesthetic gas is input to the patient, thereby causing the patient to fail to achieve the anesthesia effect and a medical accident.
[0032] Please refer to Figure 1The side of the telescopic bellows 110 away from the fixed axis 210 is connected to the anesthesia air storage bag 120 , and the side of the fixed sleeve 310 away from the fixed axis 210 is provided with an anesthesia mask 130 .
[0033] Anesthetic gas is delivered to the patient through the anesthesia gas storage bag 120, and then attached to the patient's face through the anesthesia mask 130 for the patient to inhale.
[0034] Please refer to Figure 4 and Figure 5 The insert block 250 passes through one side of the fixed shaft 210, and the insert block 250 is slidably connected to the fixed shaft 210. One side of the limit block 240 and the limit head 260 are both set to a semicircular arc shape. The limit head 260 is fixedly connected to the connecting rod 270, and the connecting rod 270 is fixedly connected to one side of the fixed sleeve 310.
[0035] By setting one side of the limiting block 240 and the limiting head 260 to be semicircular arc-shaped, the limiting head 260 can be effectively pressed against the limiting block 240 .
[0036] Please refer to Figure 2 and Figure 3 One end of the extrusion spring 350 is fixedly connected to the inner wall of the piston cylinder 320, and the other end of the extrusion spring 350 is fixedly connected to the piston 330. The piston rod 340 passes through the fixed sleeve 310 and fits on one side of the fixed shaft 210. Two groups of inflatable sealing rings 370 are provided, and both groups of inflatable sealing rings 370 are fixedly connected to the inner wall of the fixed sleeve 310.
[0037] The piston 330 squeezes the gas inside the piston cylinder 320 into the inflatable sealing ring 370, effectively enhancing its sealing effect.
[0038] When in use, the medical staff will dock the fixing sleeve 310 with the fixing shaft 210 during installation, so that the arc surface on the limit head 260 fits with the arc surface on the limit block 240, and the limit block 240 is forced to drive the slider 230 to squeeze the spring 220 to move to both sides, so that the limit head is inserted into the connecting groove 211, and then the limit head 260 is connected and fixed by the limit block 240, so that the fixing shaft and the fixing sleeve 310 are quickly plugged and fixed together, which effectively improves the installation speed of the medical staff, enhances the fixing effect, and prevents the telescopic bellows 110 from being pulled by external force and causing it to detach. When the fixed sleeve 310 is fitted with the fixed shaft 210, the fixed shaft 210 squeezes the piston rod 340, so that the piston rod 340 drives the piston 330 to stretch the extrusion spring 350 to move, so that the gas inside the piston cylinder 320 enters the inflatable sealing ring 370 through the connecting tube 360, and the inflatable sealing ring 370 expands, which effectively enhances the sealing effect when the fixed shaft 210 is connected to the fixed sleeve 310, and prevents leakage when the anesthetic gas is input to the patient, thereby causing the patient to fail to achieve the anesthesia effect and a medical accident. The parts not involved in the device are the same as the prior art or can be implemented by the prior art.
