Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices and relates to a water collecting cup assembly of a nitric oxide therapeutic apparatus. Background Technique

[0002] Nitric oxide is an endothelium-derived relaxing factor and has various biological effects such as relaxing vascular smooth muscle, inhibiting platelet aggregation, and participating in the main signal transduction of neurotransmitter transmission. Endogenous nitric oxide plays an important role in maintaining the vascular tone of the normal systemic and pulmonary circulations. After inhaled nitric oxide is fully combined with oxygen, the gas is rapidly metabolized into inactive NO2- and NO3- anions in the blood after passing through the pulmonary circulation and mainly exists in red blood cells, and the metabolites are excreted through the kidneys in urine.

[0003] Inhaled nitric oxide therapy can be used to treat persistent pulmonary hypertension in neonates, refractory respiratory failure, pulmonary hypertension in the perioperative period of surgery, pulmonary hypertension crisis and acute right heart failure, graft injury after lung transplantation, etc., and has treatment effects such as improving oxygenation ability, improving ventilation / perfusion ratio (V / Q ratio), reducing pulmonary hypertension, and reducing ischemia-reperfusion injury.

[0004] Currently, the commonly seen INOwill N200 nitric oxide therapeutic apparatus on the market has a water collecting cup connected to the end of the gas sampling tube of the therapeutic apparatus. The water collecting cup is connected to the main unit. The sampling tube mainly monitors NO2 entering the body, and its safety value is 3 ppm. When the safety value is exceeded, the instrument will give an alarm. During clinical treatment, the treatment parameters must be adjusted immediately to ensure treatment safety. The capacity of the water collecting cup is 10 ml and it is easy to be filled up after continuous use for more than 8 hours. It needs to be processed once every 6 hours on average, and the daily cumulative amount reaches 6080 ml. If the water in the water collecting cup cannot be removed in time, it is easy to cause blockage of the sampling tube or filter. The main unit will give an alarm, prompting: "Sampling tube or filter is blocked", and the gas generator will automatically stop working. At this time, it is usually necessary to unscrew the water collecting cup and pour out the internal water (sometimes it is also necessary to slightly shake it dry), but this method is easy to cause splashing of the water in the water collecting cup and other situations, and the operation effect is poor.

[0027] A water collecting cup assembly of a nitric oxide therapeutic apparatus, as Figures 1 to 6 shown, includes a cup body 1 and a cup cover 2 that cooperates with the cup body. Both sides of the top of the cup body 1 are provided with connecting pipes 3. The bottom of the cup body 1 is provided with an outer discharge pipe 4. The bottom of the outer discharge pipe 4 is successively connected and communicated with a flexible discharge pipe 5 and a storage bag 6. An opening and closing mechanism for controlling the flexible discharge pipe 5 is provided on the outer wall of the flexible discharge pipe 5.

[0028] The top of the flexible discharge pipe 5 is provided with a rigid pipe 7. A cylindrical connector 8 is rotatably provided on the outer wall of the rigid pipe 7. The inner wall of the connector 8 is threadedly connected to the outer wall of the outer discharge pipe 4. Both sides of the outer wall of the connector 8 are horizontally provided with operation parts 9.

[0029] The top of the rigid pipe 7 is vertically provided with a cylindrical fitting part 10. The fitting part 10 fits against the inner wall of the outer discharge pipe 4. The top of the fitting part 10 is provided with a horn-shaped guiding part 11. The end with the largest opening of the guiding part 11 is connected to the top of the fitting part 10. A sealing ring 12 is provided on the outer wall of the fitting part 10. The bottom of the outer discharge pipe 4 and the top of the rigid pipe 7 clamp the sealing ring 12.

[0030] The opening and closing mechanism includes a fixing rod 13 and a movable rod 14 that are oppositely arranged. Two parallel plates 15 are parallelly arranged at both ends of the fixing rod 13. Both ends of the movable rod 14 are movably connected to the two parallel plates 15. A connecting plate 16 is provided between the free ends of the two parallel plates 15. An elastic member 17 that is continuously in a compressed state is provided between the inner side of the connecting plate 16 and the outer side of the movable rod 14.

[0031] A long strip-shaped movable opening 18 is formed in the middle of the parallel plate 15. Both outer ends of the movable rod 14 are provided with movable parts 19. Anti-disengagement discs 20 are arranged on the outer sides of the movable parts 19. The two anti-disengagement discs 20 are movably attached to the outer sides of the two parallel plates 15, and the two movable parts 19 are both movably located in the corresponding movable openings 18.

[0032] A stabilizing column 21 is horizontally arranged on the connecting plate 16. A cylindrical rotating hole 22 is formed through the stabilizing column 21 and the connecting plate 16. An unlocking rod 23 is movably arranged through the rotating hole 22. One end of the unlocking rod 23 is rotatably connected to the outer end of the movable rod 14, and the other end is located at the outer end of the stabilizing column 21. A rotating disc 24 is arranged at the outer end of the unlocking rod 23;

[0033] An L-shaped unlocking groove 25 is formed at one end of the stabilizing column 21 close to the movable rod 14. The straight line where one end of the unlocking groove 25 close to the movable rod 14 is located is parallel to the straight line where the unlocking rod 23 is located. An unlocking part 26 is arranged on the outer wall of the unlocking rod 23. When the unlocking part 26 is engaged with the end of the unlocking groove 25 far from the movable rod 14, the distance between the movable rod 14 and the fixed rod 13 is greater than the diameter of the flexible discharge pipe 5.

[0034] U-shaped operation belts 27 are arranged on both sides of the storage bag 6, and both ends of the operation belts 27 are connected to the storage bag 6.

[0035] When the water collecting cup assembly of the nitric oxide therapeutic apparatus provided by the present utility model is in use, the cup cover 2 and the cup body 1 are connected by threads or snaps. At the same time, a sealing layer and the like are also provided between the cup cover 2 and the cup body 1 to improve the sealing performance of the two. At the same time, the two connecting pipes 3 are respectively connected to the gas sampling pipe and the filter, and then the filter is connected to the gas monitoring device.

[0036] During normal use, the opening and closing mechanism closes the flexible discharge pipe 5. At this time, the storage bag 6 (preferably a common drainage bag) is separated from the cup body 1. In this way, water will collect in the cup body 1. Then, when the water accumulates to a certain amount or after a certain period of time, the nurse records the amount of water in the cup body 1 at this time according to the scale on the cup body 1. After that, the opening and closing mechanism is opened so that the outer discharge pipe 4, the flexible discharge pipe 5, and the storage bag 6 are in a connected state. At this time, the liquid in the cup body 1 can flow into the storage bag 6. Then, the flexible discharge pipe 5 is closed through the opening and closing mechanism, and then wait for the next time to discharge water into the storage bag 6. In this way, not only can the time and amount of the discharged liquid be recorded each time, but secondly, the water in the cup body 1 can be discharged without stopping the machine; and because splashing and other situations may occur when the water in the cup body 1 is discharged, the operation effect is better; and finally, all the water is in the storage bag 6, so that the total amount of water in all cup bodies 1 during the entire cycle can be calculated more accurately.

[0037] When each structure of this application is produced, the cup body 1 and the cup lid 2 are assembled after being produced separately. The flexible discharge pipe 5 and the storage bag 6 are preferably produced integrally (according to actual situations, they can also be assembled after being produced separately). After the hard pipe 7 and the connector 8 are produced separately, the two are assembled, and finally the hard pipe 7 is connected to the flexible discharge pipe 5; or the hard pipe 7, the fitting part 10, the flexible discharge pipe 5, and the storage bag 6 are integrally produced and formed, and then the connector 8 is rotationally assembled with the hard pipe 7.

[0038] When connecting the hard pipe 7 to the outer discharge pipe 4, first insert the guiding part 11 into the bottom of the outer discharge pipe 4, and then thread the connector 8 onto the outer wall of the outer discharge pipe 4 through the operating part 9 until finally the sealing ring 12 is pressed tightly between the outer discharge pipe 4 and the hard pipe 7. In this way, the connection between the cup body 1 and the flexible discharge pipe 5 is completed; at the same time, the guiding part 11 plays a guiding role, enabling the fitting part 10 to be better inserted into the outer discharge pipe 4; secondly, the fitting part 10 and the sealing ring 12 improve the sealing performance of the connection between the outer discharge pipe 4 and the cup body 1.

[0039] When the flexible discharge pipe 5 is clamped usually, the unlocking part 26 is located outside the unlocking groove 25 at this time. Thus, under the elastic force of the elastic member 17, the movable rod 14 moves towards the fixed rod 13, and the flexible discharge pipe 5 is hermetically clamped through the fixed rod 13 and the movable rod 14; when draining the water in the cup body 1, a nurse holds the position of the fixed rod 13 with one hand, holds the rotating disc 24 with the other hand and pulls the rotating disc 24 outwards, and makes the unlocking part 26 snap into the unlocking groove 25. Until the unlocking part 26 moves to the maximum distance, rotate the rotating disc 24 to make the unlocking part 26 snap into the bent part of the unlocking groove 25. At this time, the unlocking groove 25 can fix the position of the unlocking rod 23 through the unlocking part 26. At the same time, the unlocking rod 23 pulls the movable rod 14 to move, and makes the movable rod 14 and the fixed rod 13 loosen the flexible discharge pipe 5, so that the liquid in the cup body 1 can flow out.

[0040] After the water in the cup body 1 is emptied, after rotating the rotating disc 24, the unlocking part 26 rotates to the long strip position of the unlocking groove 25, and then the elastic member 17 drives the movable rod 14 to move towards the fixed rod 13, and finally clamps the flexible discharge pipe 5. During the movement of the movable rod 14, the unlocking rod 23 acts on the middle of the movable rod 14, and the two elastic members 17 act on both ends of the movable rod 14, so as to ensure the movement stability of the movable rod 14; at the same time, the anti-disengagement disc 20 can also ensure that the movable rod 14 moves along the length direction of the movable opening 18, ensuring the movement stability of the movable rod 14.

[0041] When draining the water in the cup body 1, the nurse can also insert both hands into the two operation belts 27, and then pull the storage bag 6 outwards, so as to form a negative pressure state in the cup body 1 and accelerate the outflow of the water in the cup body 1.

[0042] The above description is only a description of the preferred embodiments of the present invention, and does not limit the scope of the present invention in any way. Any changes and modifications made by those of ordinary skill in the field of the present invention according to the above disclosure are within the protection scope of the claims.
