Description

Nutrition Feeding Bag

technical field

The utility model belongs to the technical field of medical equipment, in particular to a nutritional feeding bag.

Background technique

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.

In the disclosed Chinese patent literature, it can be seen that all the technical information about the corresponding equipment for delivering nutrient solution to patients, such as the "gastrointestinal infusion set" recommended by the authorized announcement number CN2208424Y, the "disposable enteral nutrition infusion set" provided by CN2612395Y and "A kind of enteral nutrition bag" introduced by CN202036590U.

The above-mentioned CN2208424Y can insert the infusion cannula into the patient's gastric tube or anal canal to deliver the corresponding nutrient solution to the patient's stomach or intestines; the above-mentioned CN2612395Y can introduce the nutrient solution into the patient's intestine through the infusion cannula; The fistula provides nutrient solution from the anus to the patient's intestines. These patent schemes that are not limited to examples have the following disadvantages: they are not suitable for feeding patients with relatively rich nutrition such as viscous rice soup and dish soup to patients whose pathological conditions are stable and in the recovery stage. Runny.

The "nasal feeding liquid diet input bag" recommended by the authorized announcement number CN2907731Y, the "feeding bag" provided by the announcement number CN103054720A, the "feeding bag with temperature display" introduced by the authorized announcement number CN202620264U, and the "medical feeding bag" disclosed by the announcement number CN102908252A "It can directly deliver various nutrient-rich juices to the patient's stomach. As far as the structure is concerned, these patented solutions have a common feature: the end of the bag body facing upwards in the use state forms a liquid filling port. On the liquid filling port Equipped with a liquid filling port plug cover; the end of the bag facing downwards in use is connected to one end of an output hose by means of heat fusion welding, and the other end of the output hose is combined with a liquid outlet joint, and the output hose The pipeline is equipped with a flow regulating control device and a Murphy's dropper (also called a Murphy's dropper, transliteration) and the like. 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, so not only causes inconvenience to use, but also is not conducive to saving resources while increasing the cost burden of patients.

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 one of these two situations occurs, the sanitation of the nutrient solution in the bag will be affected.

For the above-mentioned prior art, there is a need for improvement. For this reason, the applicant has made a beneficial design and finally formed the technical solution to be introduced below.
