Abstract
Description
TECHNICAL FIELD
[0001] The present application relates to a connector, in particular to a respirator adapter connector and its auxiliary chamber. BACKGROUND
[0002] Respimat is a common clinical spray device, mainly loaded with long-acting bronchodilators, and the main administration method is to spray the drug in the form of aerosol. The respirator pipeline needs to be disconnected and reconnected at least twice before and after spraying the drug.
[0003] As shown in Figure 6 , when a spray-type drug 60 such as Respimat is to be administered clinically, a respirator pipeline 61 needs to be disconnected and connected to a T-shaped pipe 62, which is a three-way pipe with a left opening 621, a right opening 622, and a vertical lower opening 623 extending on both sides of the T-shaped pipe. The disconnected respirator pipeline 51 is connected to the left opening 621 and the right opening 622, and the lower opening 623 is connected to an adapter connector 63 that interfaces with the spray-type drug 60. Taking a gas 64 traveling from left to right (arrow direction in the figure) as an example, when the drug of the spray-type drug 60 is pushed out, the gas 64 will also transport the drug to the patient, achieving the effect of respiratory administration.
[0004] However, the current actual clinical problem is that during the process of disconnecting the respirator and reconnecting it, water vapor splashed from the respirator may carry infectious bacteria, increasing the risk of infection for medical staff. At the same time, because the pipeline is exposed to the air, it cannot maintain a closed state, increasing the risk of infection for patients. Meanwhile, as shown in Figure 6 If the top end of the spray-type drug 60 has a gap, it is easy to cause the drug of the spray-type drug 60 to leak due to improper connection caused by insufficient length or improper shape of the adapter connector 63.
[0005] On the other hand, repeated administration causes the respirator to be disconnected and connected multiple times, which may cause the pipeline of the respirator to fail to maintain a closed state or cause insufficient gas pressure, causing the expanded alveoli to collapse and expand again, causing shear force injury, and causing secondary damage to the alveoli.
[0006] Furthermore, since the drug needs to pass through the adapter connector 63 to reach between the left opening 621 and the right opening 622 of the T-shaped pipe 62, it can be successfully transported to the patient by the gas 64, but in reality, most of the drug still remains in the adapter connector 63 and cannot be effectively administered to the patient.
[0007] Even though the existing adapter for the specific medicine of salbutamol spray, such as the respirator adapter of the brand RTC 26-C, the air tightness of the adapter is still not good, and there is still a small air flow leakage every time the cover is opened to connect the spray, increasing the chance of leakage of the bacteria infection, on the other hand, the space of the pipe of the RTC 26-C is small, and the salbutamol spray cannot be well expanded after being sprayed, reducing the absorption effect of the medicine, and further, the respirator adapter of the RTC 26-C is only suitable for a single salbutamol spray, and the clinical application is also more limited.
[0008] Therefore, there is a lack of an improved solution to the above problems or at least a solution that can solve or replace the above problems. SUMMARY
[0009] In order to solve the risk of medical staff and patients caused by the need to repeatedly disconnect the respirator during the current clinical drug delivery, which cannot maintain a clean or closed state, the present application provides a respirator adapter to solve the above problems.
[0010] The respirator adapter of the present application comprises a drainage valve T-shaped adapter and an auxiliary cavity detachably connected with the drainage valve T-shaped adapter, wherein: the drainage valve T-shaped adapter comprises a T-shaped adapter and a drainage valve structure; the T-shaped adapter is a hollow pipe body and comprises a first opening and a second opening extending in parallel to the left and right, which are in gas communication with each other, and a third opening arranged in a vertical direction between the first opening and the second opening; the third opening has a tapered neck portion and an auxiliary cavity receiving portion at the junction of the first opening and the second opening, the inner diameter of the auxiliary cavity receiving portion is slightly larger than that of the tapered neck portion, and the third opening is adapted to the drainage valve structure to extend or retract to close or open the third opening; the auxiliary cavity is a cylindrical hollow pipe body with both ends open as a drainage valve fitting opening and another end as a spray fitting opening; and the drainage valve fitting opening of the auxiliary cavity extends into the pipe body with a cavity partition plate, which at least partially divides the interior of the auxiliary cavity into two chambers.
[0011] The drainage valve structure comprises a shielding piece, a top abutting portion, a connecting portion connecting the shielding piece and the top abutting portion, and a stop ring sleeved outside the shielding piece, wherein: the size of the shielding piece is adapted to the size of the junction between the third opening and the first opening and the second opening; the connecting portion comprises a resilient mechanism and a spacing portion; the stop ring is sleeved outside the shielding piece, the diameter of which is slightly smaller than the inner diameter of the third opening, and has a ring portion and a stop piece, the stop piece extends vertically upward from the top of the ring portion; and the top abutting portion is a porous piece adapted to the tubular passage of the third opening.
[0012] The drain valve structure comprises a shielding sheet, a top abutting part and a connecting part connecting the shielding sheet and the top abutting part, wherein the shielding sheet is sized to fit the intersection between the third opening and the first and second openings; the connecting part comprises a spring mechanism and a spacing part; the top abutting part is a porous sheet body fitting the third opening tubular channel, with a top abutting column extending from the middle to the outside of the third opening, and the end of the top abutting column is bifurcated.
[0013] The spring mechanism is a spring.
[0014] The top end of the cavity partition plate is provided with a gap to connect the bifurcated end of the top abutting column.
[0015] The T-shaped joint is provided with a fourth opening fitting a certain amount of spray inhalant joint at the other part between the first and second openings.
[0016] The auxiliary cavity is provided with an opening fitting a certain amount of spray inhalant joint.
[0017] The application also provides the auxiliary cavity in the above respirator fitting joint, which is a cylindrical hollow tube body with both ends open as a drain valve fitting opening and another end as a spray inhalant fitting opening, the drain valve fitting opening extends to the inside of the tube body with a cavity partition plate, which at least partially divides the inside of the auxiliary cavity into two chambers.
[0018] The top end of the cavity partition plate is provided with a gap.
[0019] The auxiliary cavity is provided with an opening fitting a certain amount of spray inhalant joint.
[0020] From the above description, the application has the following advantages:
[0021] 1. The present application is designed with male and female structures, using a short connector with a flow valve connected to the respirator pipeline. When medication is to be administered, another suction cavity connected to the medication is connected. Through the design of the gas flow channel formed by the combination of the flow valve structure, the spacer, and the cavity partition, the airflow of the T-shaped connector is successfully brought to the location of the sprayed medication, completely or almost completely entraining the patient for inhalation, achieving better drug administration results. The design of the auxiliary cavity allows the medication spray to expand appropriately, increasing the effect of drug absorption. The respirator adapter provided by the present application can be widely used for various sprays, including but not limited to Respimat, MDI, or SVN, etc. When the administration is complete, the spray tank body and the auxiliary cavity are removed from the flow valve structure, and the rebound mechanism returns the shielding piece of the flow valve structure to its original position and closes the third opening to the outside, returning to the normal state of the respirator pipeline.
[0022] 2. Therefore, the present application can greatly reduce the risk of infection of medical staff caused by the splash of water vapor from the respirator during the process of disconnecting the respirator and reconnecting it. At the same time, because the pipeline is exposed to the air, it cannot maintain a closed state, increasing the risk of infection of the patient. Because the airflow is successfully guided to the administration end, the medication can be completely or almost completely successfully brought to the patient. BRIEF DESCRIPTION OF DRAWINGS

[0069] As shown in the present application and claims, unless the context clearly indicates otherwise, "one", "a", "an" and / or "the" do not refer to the singular, but also include the plural. Generally speaking, the terms "include" and "contain" only indicate the inclusion of steps and elements that have been explicitly identified, and these steps and elements do not constitute an exclusive list, and the method or device can also include other steps or elements.
[0070] Please refer to Figure 1 The respirator adapter 10 provided by the present application comprises a drainage valve T-shaped joint 11 and an auxiliary cavity 12 detachably connected with the drainage valve T-shaped joint 11.
[0071] <T-shaped joint>
[0072] First preferred embodiment
[0073] Please also refer to Figure 2The first preferred embodiment of the drainage valve T-connector 11 includes a T-connector 111 and a drainage valve structure 113.
[0074] The T-connector 111 is a hollow tube and includes a first opening 1111 and a second opening 1112 extending parallel to the left and right, and a third opening 1113 disposed vertically between the first opening 1111 and the second opening 1112. The first opening 1111, the second opening 1112 and the third opening 1113 are in gas communication with each other.
[0075] The third opening 1113, connecting the first and second openings, has a tapered neck 11131 and an auxiliary cavity receiving portion 11132. The inner diameter of the auxiliary cavity receiving portion 11132 is slightly larger than that of the tapered neck 11131. A drainage valve structure 113 is adapted to the third opening 1113. The drainage valve structure 113 includes a shielding plate 1131, a top abutment portion 1133, a connecting portion 1132 connecting the shielding plate 1131 and the top abutment portion 1133, and a stop ring 1134 sleeved on the outside of the connecting portion 1132. Figure 2 As shown, the size of the shielding plate 1131 is adapted to the size of the interface between the third opening 1113 and the first opening 1111 and the second opening 1112. The connecting part 1132 preferably includes a spring mechanism 11321 and a spacer part 11322. The spring mechanism 11321 can be, for example, a spring, which can make the drainage valve structure 113 spring back to its original position. The spacer part 11322 is a flat plate, which can temporarily separate the pipe between the first opening 1111 and the second opening 1112. In this embodiment, the stop ring 1134 is fitted over the outside of the connecting portion 1132, and its diameter is slightly smaller than the inner diameter of the third opening 1113. It has a ring portion 11341 and a stop piece 11342. The stop piece 11342 extends vertically upward from the top of the ring portion 11341, and preferably has an shape adapted to fit the connecting portion 1132. When the ring portion 11341 is fitted over the shielding piece 1131, the stop piece 11342 is precisely attached to the side of the connecting portion 1132. The spring-loaded mechanism 11321 is disposed inside the ring portion 11341 and abuts against the stop piece 11342, confining it within the ring portion 11341 and allowing it to compress and release within it.
[0076] In this preferred embodiment, the abutment portion 1133 is a disc-shaped porous plate that is also adapted to the tubular channel of the third opening 1113. When the drainage valve structure 113 extends to the first and second openings 1111 and 1112, the abutment portion 1133 can abut against the junction of the tapered neck 11131 and the auxiliary cavity receiving portion 11132 to achieve the function of limiting the position, and at the same time, it can compress the rebound mechanism 11321.
[0077] Similarly, Figure 2 As shown, the T-connector 111 may further have a fourth opening 1114 between the first opening 1111 and the second opening 1112, which is adapted to a certain amount of metred-dose inhaler (MDI) connector.
[0078] Second preferred embodiment
[0079] Please refer to Figure 3 The second preferred embodiment of the T-type connector 111 of the present invention is basically the same as the first preferred embodiment described above, but the difference is that this second embodiment does not include a stop ring 1134 sleeved on the outside of the shielding plate 1131, and further extends a top abutment post 11331 from the middle of the top abutment portion 1133 to the outside of the third opening 1113, and the end of the top abutment post 11331 is forked.
[0080] Third preferred embodiment
[0081] The third preferred embodiment of the T-type connector 111 of the present invention is basically the same as the first preferred embodiment described above, but the difference is that this third embodiment is provided with a magnetic attraction mechanism (not shown in the figure) at the junction of the auxiliary cavity receiving part 11132 and the tapered neck 11131 of the third opening 1113, such as an annular magnetic block. At the same time, there is another matching magnetic block on the annular periphery of the shielding plate 1131 of the drainage valve structure 113, which can attract and fix the two to each other. Therefore, this embodiment can be used with the spring mechanism 11321 or the abutment post 11331 used in the first or second embodiment to make the drainage valve structure 113 extend from the third opening 1113 to the space between the first and second openings 1111 and 1112, and the entire drainage valve structure 113 can be reset and restored by the magnetic attraction mechanism.
[0082] <Auxiliary cavity>
[0083] First preferred embodiment
[0084] Please continue with the matching reference. Figure 4A The auxiliary cavity 12 is a cylindrical hollow tube with two open ends, one being a drainage valve adapter opening 121 and the other being an injector adapter opening 123.
[0085] The first preferred embodiment of the auxiliary cavity 12 is in conjunction with the first preferred embodiment of the T-shaped joint 111. The drainage valve adapter opening 121 extends a cavity partition 122 inside the tube body, which at least partially separates the interior of the auxiliary cavity 12 into two chambers. The cavity partition 122 can extend only partially inside the auxiliary cavity 12 or extend entirely inside the auxiliary cavity 12. The bottom of the auxiliary cavity 12 is adapted to accommodate any aerosol type of medicament, such as a Respimat spray, and preferably the length and shape of the bottom of the auxiliary cavity 12 is adapted to the medicament, such as an ellipse.
[0086] Further, the side of the auxiliary cavity 12 can also be provided with an opening adapted to the adapter of the metered-dose inhaler (MDI).
[0087] Second preferred embodiment
[0088] Please continue to refer to Figure 4B The second preferred embodiment of the auxiliary cavity 12 is in conjunction with the second preferred embodiment of the T-shaped joint 111, and further provided with a notch 1221 at the top end of the cavity partition 122 to accommodate the bifurcated end of the abutting column 11331.
[0089] <Respirator adapter joint>
[0090] Please continue to refer to Figure 5A With Figure 5B With the first preferred embodiment described above, the respirator adapter joint 10 of the present application is connected to the general respirator tube 20 by connecting the first opening 1111 and the second opening 1112 of the T-shaped joint 111 in the drainage valve T-shaped joint 11, preferably the first opening 1111 and / or the second opening 1112 have any structure that can be tightly fitted with the respirator tube 20, which is not limited by the present application, only the structure that enables the respirator tube 20 to be airtight tightly fitted with the first opening 1111 and the second opening 1112 is applicable to the present application. At this time, when the drainage valve T-shaped joint 11 of the present application has not been connected to the auxiliary cavity 12, the shielding piece 1131 of the drainage valve structure 113 adapted to the third opening 1113 of the present application maintains the connection at the third opening 1113, and the first opening 1111 only maintains a single unobstructed channel with the second opening 1112, which is used for gas transportation in the general case of the respirator tube 20 without medication.
[0091] Next, please refer to Figure 5BWhen it is time to administer the drug, first the top abutting portion 1133 of the drainage valve structure 113 of the third opening 1113 abuts and engages with the cavity partition 122 of the drainage valve fitting opening 121 of the auxiliary cavity 12, then the drainage valve structure 113 is abutted in the space between the first opening 1111 and the second opening 1112 of the T-shaped joint 111, and stops at the abutment of the top abutting portion 1133 and the intersection of the tapered neck portion 11131 and the auxiliary cavity receiving portion 11132, so that the top of the auxiliary cavity 12 is accommodated inside the auxiliary cavity receiving portion 11132 of the third opening 1113, and at the same time the rebound mechanism 11321, such as a spring, is compressed, at this time the spacing portion 11322 of the drainage valve structure 113 and the cavity partition 122 of the auxiliary cavity 12 are connected and form the same plane, so that the original straight channel of the respirator pipeline 20 is formed into a U-shaped channel to the third opening 1113, so that a gas flow 30 passes through. It is worth noting that when the drainage valve structure 113 of the present application is abutted in the space between the first opening 1111 and the second opening 1112 of the T-shaped joint 111, it may occupy 1 / 2, 2 / 3 or all of the space, basically only the original straight channel of the respirator pipeline 20 is formed into a U-shaped channel to the third opening 1113 to achieve the effect claimed by the present application. At the same time, the injection agent fitting opening 123 at the bottom of the auxiliary cavity 12 can be connected and connected with the package tank of an injection agent 40, which is preferably a Respimat, when the injection agent 40 is triggered to be injected in the direction of the third opening 1113, the gas flow 30 will carry the injection agent 40 continuously in the direction of the patient, achieving the effect of drug administration.
[0092] The gas flow channel design formed by the combination of the drainage valve structure 113, the spacing portion 11322 and the cavity partition 122 successfully enables the original gas flow 30 of the T-shaped joint 111 to be completely or almost completely carried to the patient for inhalation, achieving better drug administration effect.
[0093] When the drug administration is completed, only the injection agent 40 tank together with the auxiliary cavity 12 is disassembled from the drainage valve structure 113, and the rebound mechanism 11321 returns the shielding piece 1131 of the drainage valve structure 113 to the original position and closes the third opening 1113 to the outside, and returns to the original state of the respirator pipeline 20 in general use.
[0094] The basic mechanism of the second preferred embodiment is the same as the above, only in that the top end of the top abutting part 1133 of the drainage valve structure 113 is bifurcated, and after the top abutting part 1133 of the drainage valve structure 113 abuts and engages with the gap 1221 of the cavity partition 122 of the drainage valve matching opening 121 of the auxiliary cavity 12, the drainage valve structure 113 is abutted to the space between the first opening 1111 and the second opening 1112 of the T-shaped joint 111, and at the same time, the rebound mechanism 11321 is compressed to make the drainage valve structure 113 deeply enter the pipeline between the first opening 1111 and the second opening 1112 to form the same gas flow channel design as above.
