Nutrient feeding bag

Abstract

The invention relates to a nutrient feeding bag, and belongs to the technical field of medical apparatuses. The nutrient feeding bag comprises a bag body and an output hose pipe, wherein the middle part of one end, facing upwards in the use state, of the bag body is provided with a liquid inlet, the liquid inlet is connected with a liquid inlet plug cover, and the output hose pipe is provided with a Murphy dropper and a flow adjusting control device. The nutrient feeding bag is characterized in that the middle part of one end, facing downwards in the use state, of the bag body is fixedly connected with one end of a random connecting pipe, the other end of the random connecting pipe forms a connecting sleeve engaging mechanism, one end of the output hose pipe is matched with a connecting sleeve, and the other end of the output hose pipe is fixedly connected with a liquid outlet joint. The nutrient feeding bag has the advantages that when the connecting sleeve is connected with the connecting sleeve engaging mechanism, the random connecting pipe is connected with the output hose pipe; when the connecting sleeve is disconnected from the connecting sleeve engaging mechanism, the random connecting pipe is separated from the output hose pipe; the waste of resources is avoided, and the burden of a patient is reduced; the rapid effect of bag change without pipe change is realized; the structure is simple, and the operation is convenient; the pollution to a nutrient solution in a bag cavity is avoided.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a nutritional feeding bag. Background technique [0002] In medical clinics, the feeding of self-chewing and spontaneous swallowing difficulties has long been troubled by medical workers in the medical department and even the family members of patients, especially because of the lack of suitable nutrient solution feeding devices, so it is usually performed regularly or irregularly in clinical practice. The patient is injected with nutrient solution by means of a syringe, or the nutrient solution is delivered to the patient along with the medicine in the form of drip (drop needle). This method has at least the following deficiencies: first, the monotonous (single) nutrient substance is not conducive to accelerating the process of patients' physical recovery; second, the work intensity of medical workers is high.

Feeding bags of this structure often expose the following disadvantages during actual use: First, due to the lengthy output hose is easy to block (the longer the infusion is stopped, the higher the probability of blockage), and once blocked, it often It cannot be dredged, so when it is blocked, the bag body, the output hose, the flow adjustment control device on the output hose, the Murphy dropper, etc. can only be completely replaced, which will cause waste of resources on the one hand and increase on the other. The cost burden of the large patient; second, since the output hose and the bag cannot be separated randomly, when changing the bag containing different nutrient solutions, only the output hose (including the flow rate on the output hose) Adjustment control device, Murphy's dropper, etc.) are replaced together, which not only causes inconvenience in use, but also is not conducive to saving resources and increasing the cost burden of patients

[0006] In addition, after the liquid filling port cap plug of the aforementioned patent is placed in the liquid filling port, the following two situations are generally undesirable: one is that the liquid filling port plug automatically retreats from the liquid filling port, or the gap between the liquid filling port and the liquid filling port is closed. It is in a state of cooperation rather than cooperation; the second is that the sealing effect between the liquid filling port plug cover and the liquid filling port is poor

No matter any situation occurs in these two situations, it will affect the sanitation of the nutrient solution in the bag.
