Description
Technical Field
The invention belongs to the field of medical appliances, and particularly relates to a self-sealing type water collecting device for a breathing machine pipeline.
Background
When the patient has serious illness and cannot breathe spontaneously, the patient needs to use a breathing machine to assist or be forced to breathe so as to maintain basic vital signs. The ventilator circuit includes a Y-tube assembly and a water collection cup assembly in addition to the primary airway. Two ends of the Y-shaped pipe component are connected into an air pipeline, and the third end is communicated with the water collecting cup component. The water collecting cup component is mainly used for receiving water formed by liquefying wet and hot gas when a patient breathes, and because the capacity of the water collecting cup component is usually designed to be smaller, medical staff is required to take down the water collecting cup component before the water collecting cup component is fully collected, pour out the water in the water collecting cup component, and continuously connect the water collecting cup component back to the Y-shaped pipe component for use, or replace a new water collecting cup component to connect the water collecting cup component to the Y-shaped pipe component for use, and the replacement frequency is usually 3-4 hours/time. In the replacing process, after the water collecting cup component is detached, the joint of the Y-shaped pipe component and the water collecting cup component is in an open state. In the prior art, a corresponding self-sealing measure such as a gravity self-sealing structure is adopted for the Y-shaped pipe assembly, so that when the water collecting cup assembly is taken down, the lower end of the Y-shaped pipe assembly is self-sealed, bacteria in the external environment are prevented from entering an air pipeline from the Y-shaped pipe assembly, and the infection of a patient is aggravated due to the inhalation of the patient; and also avoids the infection of medical staff who replace the water cup by germs contained in the gas exhaled by the patient (such as the patient in the ICU is usually seriously ill, and a great amount of germs are also contained in the gas exhaled by the patient). However, in the prior art, there is no measure for effectively preventing the rim of the water collecting cup assembly from being sealed after the water collecting cup assembly is replaced. If the water collecting cup component is not sealed, a large amount of germs are carried in the water collecting cup component, and the splashing or volatilization of the condensed water can cause medical staff to be exposed to the working environment of high-risk germs, so that the risk of great cross infection exists between the medical staff and patients.
Therefore, when the water collecting cup assembly is detached and replaced, the Y-shaped pipe assembly and the water collecting cup assembly are simultaneously closed, and when the brand new water collecting cup assembly is replaced, the Y-shaped pipe assembly and the water collecting cup assembly can be simultaneously connected, so that the need is felt.

In use, as shown in fig. 1, the Y-shaped pipe assembly 1 and the water collecting cup assembly 2 are assembled together (the assembly mode can be that the two parts are matched through threads at the contact part, which is a conventional arrangement, so the application is not limited by the matching mode), at this time, the movable plug 16 is jacked up by the jackshaft 24 from the middle part of the fixed plug 13 to expose the water flow channel 15, so that the water flow channel 15 is in an opened state, and meanwhile, the movable cover 23 is screwed to the position that the second through hole 231 of the movable cover is completely aligned with the first through hole 221 of the fixed cover 22, so that the water collecting cup assembly 2 is in a state capable of normally collecting condensed water as shown in fig. 1 and 2. The two air flow channels 11 of the Y-shaped pipe assembly 1 are respectively responsible for air inlet and air outlet of the breathing machine pipeline, and condensed water formed by liquefying wet and hot air during breathing of a patient flows into the cup body 21 from the arrow direction a in fig. 1 to be collected.
When the amount of collected condensate is observed through the cup 21 to quickly exceed the movable cover 23, the healthcare worker needs to take the in-use water collection cup assembly and replace the new water collection cup assembly. The specific operation is as follows: the rotary link 25 is connected to the lower movable cover 23, so that the movable cover 23 can be rotated around the top shaft 24 by a certain angle, and then the movable cover 23 is rotated until the second through hole 231 thereof is completely staggered from the first through hole 221 of the fixed cover 22, as shown in fig. 4, that is, condensed water cannot continuously flow into the cup 21 through the first through hole 221 and the second through hole 231. The intermediate states of fig. 2 to 4 are seen in fig. 5. The movable cover 23 and the fixed cover 22 together realize sealing of the cup opening of the cup body 21, and condensed water is collected into the cup body space below the movable cover 23 and the fixed cover 22, as shown in fig. 3. After that, the water collecting cup assembly 2 is disassembled, and the Y-shaped pipe assembly 1 and the water collecting cup assembly 2 are separated, as shown in fig. 6 and 7, respectively. At this time, the movable plug 16 falls under the action of gravity to seal the water flow channel 15 formed in the middle of the fixed plug 13, so that one side of the Y-shaped pipe assembly is also sealed. Finally, the packaging cover 26 is taken off from the cup bottom of the cup body 21 and assembled at the cup opening, so that the condensed water in the water collecting cup assembly 2 is completely sealed. So far, this embodiment has realized when dismantling and changing the water collection cup subassembly, and Y type pipe subassembly and water collection cup subassembly seal simultaneously, and after the brand-new water collection cup subassembly of changing inserts Y type pipe subassembly, Y type pipe subassembly and water collection cup subassembly again can be like the state realization of fig. 1 and switch on simultaneously, have realized the safe pollution-free of process of changing the water collection cup subassembly, avoid comdenstion water/germ to cross infection patient and medical personnel of overflow in the change process.
In particular, in this embodiment, the fixed cover 22 and the movable cover 23 are circular sheet structures with mutually matched molded surfaces, and the sections of the two structures along the center to the outer edge are in a cambered surface structure with downward depressions, and the first through hole 221 and the second through hole 231 are formed at the lowest position of the cambered surface structure.
In particular, in this embodiment, by designing the packaging cover 26 that can be assembled and connected with the cup opening and the bottom of the cup body 21, after the water collecting cup assembly is produced and shipped, since the cup opening of the cup body 21 is assembled together with the Y-shaped tube assembly, the packaging cover 26 can be assembled to the bottom of the cup body 21, which is convenient for the product to be packaged in the field and does not generate extra packaging work. Meanwhile, when the water collecting cup assembly is used for collecting condensed water and needs to be disassembled and replaced, the packaging cover 26 can be disassembled and assembled at the cup mouth by the cup bottom of the cup body 21, so that the condensed water in the water collecting cup assembly 2 is completely sealed, and the condensed water remained on the upper surface of the fixed cover 22 is prevented from containing germs to infect medical staff.
Further, the leak stopping mechanism adopted in the present embodiment includes a housing 27 disposed at the bottom of the cup 21, a rubber block 271 disposed in the housing 27, and a protruding ring 251 disposed in the circumferential direction of the connecting rod 25; a concave ring (not shown) which is in interference fit with the convex ring 251 and coincides with the projection of the convex ring position is provided in the rubber block 271. When the connecting rod 25 rotates, due to interference fit between the peripheral convex ring 251 and the concave ring on the rubber block 271, condensed water cannot overflow from the gap between the convex ring 251 and the concave ring, and the material property of the rubber block 271 can enable the connecting rod 25/the convex ring 251 to complete rotation against the friction force of interference fit under the action of enough external force, namely, the condensed water in the cup 21 cannot leak from the junction of the connecting rod 25 and the cup 21 when the connecting rod 25 rotates.
Further, the protruding ring 251 and the recessed ring adopted in the present embodiment are provided with three rings, and of course, other ring numbers may be adopted. The number of the convex rings 251 and the concave rings is properly increased, so that the leak stopping performance of the leak stopping mechanism can be increased, and the possibility of overflowing of condensed water is reduced. Of course, the number of rings cannot be designed too much, which increases friction and difficulty in rotating the link 25.
Further, in this embodiment, a circle of sealing layer 28 is provided at the joint between the outer periphery of the movable cover 23 and the inner wall of the cup body 21. The sealing layer 28 can improve the sealing effect between the movable cover 23 and the inner wall of the cup body 21, and avoid overflow of condensed water.
Further, the assembly connection mode of the packaging cover 26 and the cup mouth and the cup bottom of the cup body 21 is a screw thread matching connection mode, and compared with a pure interference fit clamping mode, screw thread matching is firmer and convenient to assemble and disassemble. Meanwhile, the existing Y-shaped pipe assembly 1 and the water collecting cup assembly 2 are assembled in a threaded fit mode, namely, external threads are arranged at the cup mouth of the cup body 21, the same external threads are arranged at the cup bottom of the cup body 21, and internal threads which can be matched with the two external threads at the same time are arranged in the packaging cover 26, so that the assembly can be realized.
Further, the section of the movable plug 16 adopted in the embodiment is of a T-shaped structure; the section of the water flow channel 15 is also of a T-shaped structure, and the diameter of the upper part of the water flow channel 15 is the same as that of the upper part of the movable plug 16, so that the movable plug 16 can seal the water flow channel 15 after falling under the action of gravity, and the diameter of the lower part of the water flow channel 15 is larger than that of the lower part of the movable plug 16, so that the water flow channel 15 can normally flow water when the movable plug 16 is jacked up.
Further, in this embodiment, the outer edge of the bottom of the movable plug 16 is integrally formed with a plurality of strip guides 17, as shown in fig. 6, the strip guides 17 are strip-shaped, so that the normal water passing through the water flow channel 15 is not affected.
Further, in this embodiment, the handle 252 is connected to the outer side of the bottom of the cup body 21 extending from the connecting rod 25, so as to facilitate the rotation operation of the connecting rod 25.
Further, in this embodiment, the bottom center of the cup body 21 is of a concave structure; the handle 252 is arranged in the concave structure and extends out a distance not exceeding the bottom of the cup body 21, so that the bottom structure of the water collecting cup assembly 2 is simpler, no protruding part exists, the installation of the packaging cover 26 is facilitated, and the placement of the water collecting cup assembly 2 is facilitated after the packaging cover 26 is detached.
Example two
As shown in fig. 9, the difference from the first embodiment is that in the present embodiment, the leak-stopping mechanism includes a water seal 29 provided in the thickness direction of the cup 21 and closely fitted to the outer periphery of the link 25 at the junction between the link 25 and the cup 21. The water sealing ring 29 in the market is made of rubber materials, so that the cost is very low, a certain sealing waterproof effect is achieved, meanwhile, the friction force between the water sealing ring 28 and the connecting rod 25 is overcome, large force is not needed, and therefore the connecting rod 25 can be rotated, and the movable cover 23 is driven to rotate.
Finally, it is noted that the above-mentioned preferred embodiments are only intended to illustrate rather than limit the invention, and that, although the invention has been described in detail by means of the above-mentioned preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the scope of the invention as defined by the appended claims.
