一种医用液位越限报警装置A medical liquid level over-limit alarm device

技术领域technical field

本发明涉及液位越限报警技术领域，具体是一种医用液位越限报警装置。The invention relates to the technical field of liquid level over-limit alarm, in particular to a medical liquid level over-limit alarm device.

背景技术Background technique

当病人在医院输液时，通常需要护士或家人的看护，当液体输完时，如果未能及时发现，会给病人带来很大的麻烦甚至造成生命危险。When the patient is in the hospital for infusion, he usually needs the care of nurses or family members. When the infusion of the liquid is finished, if it is not found in time, it will bring great trouble to the patient and even cause danger to life.

目前医院在跟病人输液(打吊针或打点 滴)大多都是采用吊挂式垂直压降的方法，采用输液网套对输液瓶进行吊挂，不仅在寻找合适的输液网套时会浪费一些时间，而且也只有在输液瓶放入输液网套后才能将输液器扎入输液瓶中，整个过程不仅浪费时间，而且也相对繁琐，并且随着长时间的使用，输液网套还会出现老化，无法使用的情况。At present, most hospitals use the hanging vertical pressure drop method for infusion with patients (suspension or drip), and the infusion net sleeve is used to hang the infusion bottle, which not only wastes some time when looking for a suitable infusion net sleeve , and the infusion set can only be inserted into the infusion bottle after the infusion bottle is put into the infusion net. Unusable situation.

而且输液时还有一个重要的问题是：当输液瓶内滴液用尽时， 需要请护士拔针或续瓶，稍不注意，则血液可能反从血管倒流至滴液细管中，若此时需要续 瓶，则空气进入滴管，难以排除，病人还可能需要二次打针，增加了护士的工作强度的同时 病人还要忍受再次打针带来的痛苦；如不小心让空气进入血管，将对人体产生很不利的影 响，严重的可能引起医疗事故或医患矛盾。为此，在滴液瓶中所剩滴液不多时，病人或陪同人员需要随时观察，病人无法得到很好的休息，而陪同人员也费尽心神。In addition, there is another important problem during infusion: when the drip in the infusion bottle is used up, you need to ask the nurse to pull out the needle or refill the bottle. If you are not careful, the blood may flow back from the blood vessel to the drip tube. When the bottle needs to be refilled, the air will enter the dropper, which is difficult to eliminate. The patient may also need a second injection, which increases the work intensity of the nurse and the patient has to endure the pain caused by another injection. It has a very adverse effect on the human body, and may cause serious medical accidents or conflicts between doctors and patients. For this reason, when there are not many drops left in the drip bottle, the patient or the accompanying person needs to observe at any time, the patient cannot get a good rest, and the accompanying person is also exhausted.

所以，人们需要一种医用液位越限报警装置来解决上述问题。Therefore, people need a medical liquid level out-of-limit alarm device to solve the above problems.

本发明的工作原理：The working principle of the present invention:

套壳2上对称加工有两组滑槽2-3，两组滑槽2-3一端向下倾斜60°，伸缩杆2-12安转在滑槽2-3内，伸缩杆2-12中的连接杆2-124与夹持板2-11固定，伸缩杆2-12中的伸缩壳2-123、丝杆2-122、滑杆2-121均位于滑槽2-3内部，滑杆2-121贯穿滑槽2-3并通过滑柱与空气压缩器2-13滑动连接，丝杆2-122在与齿轮条2-31相对应的位置安装有齿轮2-14，齿轮2-14与齿轮条2-31进行齿轮传动，连接杆2-124一开始在弹簧2-125在作用下伸处伸缩壳2-123，使两组夹持板2-11之间形成的夹持空间比较小，方便对小规格尺寸的输液瓶进行夹持，当放入大规格尺寸的输液瓶时，连接杆2-124在夹持板2-11的作用下往伸缩壳2-123内收缩，以此方便对大规格尺寸的输液瓶进行夹持，当输液瓶放在承载板2-111上，由于承载板2-111为扇形结构，且承载板2-111呈坡体结构，承载板2-111的向下倾斜的坡度为10°，而且承载板2-111上通过螺丝固定有滑轮条2-112，所以导致输液瓶放置在承载板2-111上时，输液瓶在坡度为10°的坡体以及滑轮条2-112的作用下倾斜向下滑动，并在滑动的同时为承载板2-111提供向下运动的动力，承载板2-111将输液瓶上的重力通过夹持板2-11传递到伸缩杆2-12上，使得伸缩杆2-12可以在滑槽2-3内向下滑动。Two sets of chute 2-3 are symmetrically processed on thecasing 2, one end of the two sets of chute 2-3 is inclined downward by 60°, the telescopic rod 2-12 is installed in the chute 2-3, The connecting rod 2-124 of the telescopic rod 2-12 is fixed with the clamping plate 2-11. The telescopic shell 2-123, the screw rod 2-122 and the sliding rod 2-121 in the telescopic rod 2-12 are all located inside the chute 2-3. The sliding rod 2-121 runs through the chute 2-3 and is slidably connected to the air compressor 2-13 through the sliding column. The screw 2-122 is installed with a gear 2-14 and a gear 2-14 at the position corresponding to the gear rack 2-31. Gear transmission with the gear rack 2-31, the connecting rod 2-124 initially extends the telescopic shell 2-123 under the action of the spring 2-125, so that the clamping space formed between the two groups of clamping plates 2-11 can be compared It is small and convenient to hold the infusion bottle of small size. When the infusion bottle of large size is put in, the connecting rod 2-124 shrinks into the telescopic shell 2-123 under the action of the clamping plate 2-11 to This is convenient for holding large-sized infusion bottles. When the infusion bottle is placed on the carrier board 2-111, since the carrier board 2-111 is a fan-shaped structure, and the carrier board 2-111 has a slope structure, the carrier board 2- The downward slope of 111 is 10°, and the carrier plate 2-111 is fixed with a pulley bar 2-112 by screws, so when the infusion bottle is placed on the carrier plate 2-111, the infusion bottle is at a slope of 10°. Under the action of the slope and the pulley bar 2-112, the slope slides downward, and at the same time, it provides the downward movement power for the bearing plate 2-111, and the bearing plate 2-111 passes the gravity on the infusion bottle through the clamping plate 2 -11 is transmitted to the telescopic rod 2-12, so that the telescopic rod 2-12 can slide down in the chute 2-3.

伸缩杆2-12在滑槽2-3内向下滑动时，齿轮2-14与齿轮条2-31进行齿轮传动，丝杆2-122将在齿轮2-14的转动下与伸缩壳2-123进行丝杆传动，随着齿轮2-14的不断往下，伸缩壳2-123将不断伸出滑槽2-3，并最终与夹持板2-11接触，并阻止夹持板2-11继续往外运动。When the telescopic rod 2-12 slides down in the chute 2-3, the gear 2-14 and the gear rack 2-31 are geared, and the screw 2-122 will connect with the telescopic shell 2-123 under the rotation of the gear 2-14. Carry out the screw drive, with the continuous downward movement of the gear 2-14, the telescopic shell 2-123 will continue to extend out of the chute 2-3, and finally contact with the clamping plate 2-11, and prevent the clamping plate 2-11 Continue to move out.

两组夹持板2-11一开始在连接杆2-124的作用下形成一个较小的夹持空间，当大规格尺寸的输液瓶放入夹持空间内时，两组夹持板2-11在输液瓶的支撑下往外运动，使得连接杆2-124往伸缩壳2-123内运动，当夹持板2-11将输液瓶的重力传递到伸缩杆2-12上时，伸缩杆2-12将在滑槽2-3内向下运动，两组夹持板2-11也将在伸缩杆2-12往下运动的同时向中间靠拢，并与套壳2相互配合形成一个完整的圆形夹持空间，随着夹持板2-11的不断下降，丝杆2-122将在齿轮2-14的带动下与伸缩壳2-123进行丝杆传动，并将伸缩壳2-123传动出滑槽2-3，使伸缩壳2-123的右端抵在伸缩壳2-123上，对夹持板2-11进行位置固定，使得两组夹持板2-11可以形成相对稳定的夹持空间。The two sets of clamping plates 2-11 initially form a small clamping space under the action of the connecting rod 2-124. When a large-sized infusion bottle is placed in the clamping space, the two sets of clamping plates 2- 11 Move outward under the support of the infusion bottle, so that the connecting rod 2-124 moves into the telescopic shell 2-123. When the clamping plate 2-11 transmits the gravity of the infusion bottle to the telescopic rod 2-12, the telescopic rod 2 -12 will move downward in the chute 2-3, and the two sets of clamping plates 2-11 will also move toward the middle when the telescopic rod 2-12 moves downward, and cooperate with thecasing 2 to form a complete circle With the continuous lowering of the clamping plate 2-11, the screw 2-122 will be driven by the gear 2-14 and the telescopic shell 2-123 will be driven by the screw, and the telescopic shell 2-123 will be driven. Exit the chute 2-3, make the right end of the telescopic shell 2-123 abut on the telescopic shell 2-123, and fix the position of the clamping plate 2-11, so that the two sets of clamping plates 2-11 can form a relatively stable clamp holding space.
