Description

A kind of nasogastric tube combined instrument

technical field

The utility model belongs to the technical field of medical instruments, in particular to an instrument for medical postoperative care, in particular to a combined instrument for nasogastric tube.

Background technique

As a medical consumable, nasogastric tubes are widely used in clinical departments, even communities, and families due to the needs of patients, such as for gastrointestinal decompression, or feeding food and drugs through tubes. Therefore, it is particularly important for nursing staff to care for indwelling nasogastric tubes. The nasogastric tube currently used in clinical practice is a transparent silicone tube with a blind end at the front end and a side hole, which is placed in the stomach. There is a silicone tube plug next to it. When negative pressure and nasal feeding are not needed, it can directly plug the opening at the end of the gastric tube to seal the gastric tube.

In the process of tube nursing, the nurses found that the current nasogastric tube has the following deficiencies:

1. It is easy to cause gastric reflux, and it is inconvenient to discharge the liquid and gas in the negative pressure plate with a tube.

2. When pouring gastric juice, it is necessary to separate the gastric tube from the negative pressure plate, and connect it after pouring, which increases the probability of contamination.

3. When the opening of the end of the nasogastric tube and the silicone tube plug are used repeatedly, or when oily drugs are fed through the nose, the tightness of the connection is reduced and it is easy to slip off, causing leakage of gastric juice, polluting clothes, and easy to cause retrograde infection due to the opening of the tube.

4. In order to avoid the above situation after feeding drugs and food through the nose, the nurse needs to fold back the end of the gastric tube and wrap it with gauze, which makes the nursing work cumbersome and increases the workload.

Utility model content

Aiming at the above-mentioned shortcomings of the existing nasogastric tube, the utility model provides a nasogastric tube combination device, the specific structure is as follows:

A nasogastric tube combination device is composed of a screw injector 1, a shut-off valve 2 and a gastric tube assembly. The injection port of the syringe 1 is connected with one end of the gastric tube assembly through a shut-off valve 2 .

The gastric tube assembly is composed of a flexible tube 4 , an infusion regulator 5 , a hard tube 6 and an externally threaded interface 7 . Wherein, an infusion regulator 5 is sheathed on the tube body of the flexible tube 4 . One end of the flexible pipe 4 is connected with one end of the hard pipe 6 . The other end of the hard pipe 6 is connected with the external threaded interface 7 . The external thread interface 7 is used to connect with the shut-off valve 2 .

Beneficial technical effect

The infusion regulator 5 and shut-off valve 2 added in the utility model have the function of two-level closure, and double guarantees ensure the conduction and cut-off of the utility model.

Through the infusion regulator 5, the flow rate of the drainage fluid can be controlled. This is a function that previous nasogastric tubes did not have.

The infusion regulator 5 adopted by the utility model is a standard part on the infusion tube, which is convenient to purchase and low in cost. The components of the shut-off valve 2 adopted by the utility model are all standard parts, and the purchase cost is low.

The infusion regulator 5 in the utility model can move up and down along the hose 4 and be fixed, which is convenient for confirming and marking the insertion depth of the hose 4, which is intuitive, easy for medical staff to observe and judge, and also improves the comfort of users.

After adopting the utility model, when dumping gastric juice, as long as the infusion regulator 5 is closed, gas and liquid can be directly discharged. It avoids the need to separate the gastric tube from the negative pressure plate before dumping under the existing structural conditions, or avoids the reflux of gastric juice and gas caused by squeezing the negative pressure plate, thereby avoiding the danger of contamination, retrograde infection and even suffocation.

After adopting the utility model, after tube feeding of food and medicine, there is no need to turn back the gastric tube, gauze wrapping and other nursing work, only need to close the infusion regulator 5 and/or shut-off valve 2, which provides convenience for pipeline nursing, and more Leakage and contamination are reduced, the patient's comfort during tube placement is increased, and the patient's enthusiasm for tube-carrying activities is improved.

In the present utility model, the screw injector 1 and the shut-off valve 2, and the shut-off valve 2 and the gastric tube assembly are all threaded: the external thread interface 23 forming the shut-off valve 2 is connected with the screw injector 1 to form the interior of the shut-off valve 2. The threaded interface 24 is connected with the external threaded interface 7 constituting the gastric tube assembly to ensure that the two connections are firm and difficult to disconnect, avoiding the problem of liquid leakage, ensuring the cleanliness of the hospital bed and reducing the possibility of secondary pollution.

detailed description

Now describe in detail the structural features of the utility model in conjunction with the accompanying drawings.

Referring to FIG. 1 , a combined nasogastric tube device is composed of a screw syringe 1 , a shut-off valve 2 and a gastric tube assembly. The injection port of the syringe 1 is connected with one end of the gastric tube assembly through a shut-off valve 2 .

Referring to FIG. 2 , the gastric tube assembly is composed of a flexible tube 4 , an infusion regulator 5 , a hard tube 6 and an externally threaded interface 7 . Wherein, an infusion regulator 5 is sheathed on the tube body of the flexible tube 4 . One end of the flexible pipe 4 is connected with one end of the hard pipe 6 . The other end of the hard pipe 6 is connected with the external threaded interface 7 . The external thread interface 7 is used to connect with the shut-off valve 2 .

Referring to FIG. 1 , furthermore, the infusion regulator 5 is arranged on the tube body of the flexible tube 4 near the hard tube 6 side.
