Description

Technical Field

[0001] This utility model relates to the field of nasoenteric tube technology, and in particular to a nasoenteric tube that can be used for patients with poor gastric motility who require enteral nutrition. Background Technology

[0002] Patients in the intensive care unit often have decreased gastric motility or are intubated, which prevents them from eating orally. These patients need to be fed through a nasoenteric tube to deliver nutrients into the intestines in order to promote their recovery.

[0003] The existing nasoenteric tube has the following defects in use:

[0004] The placement is quite difficult, and blind placement is not easy to achieve the correct position. It requires the use of X-rays to confirm the location. In addition, a regular nasoenteric tube does not provide decompression, so a nasogastric tube needs to be placed separately for decompression. The separate placement of the two tubes increases the patient's pain.

[0005] Therefore, in order to solve the above problems, this utility model proposes a nasoenteric tube that is easy to place and can simultaneously achieve nasogastric feeding and gastric decompression. Utility Model Content

[0027] The nutrient tube 100 and the pressure-reducing tube 200 are transparent. The nutrient tube 100 has openings at both its head and tail ends that connect to the inside and outside. The pressure-reducing tube 200 is sleeved on the outside of the nutrient tube 100. The head end of the pressure-reducing tube 200 is sealed to the middle of the nutrient tube 100. A pressure-reducing channel 201 is reserved between the pressure-reducing tube 200 and the nutrient tube 100. A pressure-reducing hole 202 is opened on the side of the pressure-reducing tube 200 near its head end that connects to the inside and outside of the pressure-reducing channel 201. The tail end of the pressure-reducing tube 200 has an opening that connects to the inside and outside.

The nasogastric nutrition solution can be fed through the lumen of the feeding tube 100, and the gastric decompression can be achieved through the lumen of the decompression tube 200. The main guide wire 300 can insert the visual probe 301 into the feeding tube 100, and the feeding tube 100 can be placed under direct vision with the help of the monitor 302.

[0030] It should be noted that the head end and tail end mentioned in this technical solution refer to the two ends in the length direction of the component.

[0031] Furthermore, both the feeding tube 100 and the decompression tube 200 are X-ray impermeable, and the nasoenteric tube also includes:

[0032] The guiding wire 400 is the same length as the main guiding wire 300 and is configured to insert into and support the nutrient tube 100. If necessary, the main guiding wire 300 can be inserted into the nutrient tube 100 together with the guiding wire 400 to increase the support of the nutrient tube 100 and facilitate insertion.

[0033] In one embodiment, both the main guide wire 300 and the auxiliary guide wire 400 are guide wires, and the length of the main guide wire 300 is the same as the length of the feeding tube 100.

[0034] Furthermore, the nutrient tube 100 and the pressure-reducing tube 200 are coaxially arranged, and the wall thickness of the pressure-reducing tube 200 gradually decreases away from the head end of the pressure-reducing tube 200, so that the connection between the nutrient tube 100 and the pressure-reducing tube 200 forms a smooth transition.

[0035] Furthermore, the nutrient tube 100 has a plurality of nutrient holes 101 arranged radially along the nutrient tube 100 at its head end. The inner wall of the nutrient hole 101 forms the opening at the head end of the nutrient tube 100. Adjacent nutrient holes 101 are arranged alternately along the length of the nutrient tube 100. Adjacent nutrient holes 101 are arranged alternately on both sides of the radial direction of the nutrient tube 100.

[0036] The nutrient hole 101 is an elliptical nutrient hole 101, and the major axis of the nutrient hole 101 is set along the length direction of the nutrient tube 100.

[0037] In one embodiment, the number of nutrient holes 101 is 3, and the long diameter of the nutrient holes 101 is 1 cm.

[0038] Furthermore, the pressure relief holes 202 are arranged radially along the pressure relief tube 200, and a set of pressure relief holes 202 is provided on each of the two radial sides of the pressure relief tube 200. There are multiple pressure relief holes 202 in each set, and adjacent pressure relief holes 202 in each set are arranged sequentially at intervals along the length direction of the pressure relief tube 200.

[0039] In one embodiment, the number of pressure relief holes 202 is 6, the pressure relief holes 202 are divided into two groups, each group has 3 pressure relief holes 202, the diameter of the pressure relief holes 202 is 1cm, and the maximum distance between the pressure relief holes 202 is 15cm.

[0040] The nasoenteric tube further includes a connector 500, the head end of which is connected to the opening at the tail end of the feeding tube 100 and the opening at the tail end of the decompression tube 200. The tail end of the connector 500 is provided with a first interface 501 and a second interface 502 arranged side by side. The first interface 501 is connected to the feeding tube 100, and the second interface 502 is connected to the decompression channel 201.

[0041] The connector 500 is further provided with an openable and closable third interface 503 at its tail end. The third interface 503 is connected to the nutrient tube 100 and is connected in parallel with the first interface 501. This allows the third interface 503 to be opened for backup when the first interface 501 is blocked. When the nutrient tube 100 is blocked and needs to be cleared, the third interface 503 and the first interface 501 can be cleared simultaneously, increasing the success rate of clearing the tube.

[0042] In one embodiment of this utility model, the length of the nutrient tube 100 and the length of the main guide wire 300 are both 130cm, the diameter of the nutrient tube 100 is 3mm, and the nutrient tube 100 is made of PUR material.

[0043] The pressure reducing tube 200 is 80cm long and 5mm in diameter;

[0044] The tail end of the pressure-reducing tube 200 is aligned with the tail end of the nutrient tube 100. Scales are provided on the outer side of the pressure-reducing tube 200 and the outer side of the nutrient tube 100. The readings of the scales are continuously set from the head end of the nutrient tube 100 to the tail end of the pressure-reducing tube 200, from small to large. The pressure-reducing hole 202 is correspondingly set between 50-65cm.

[0045] How to use:

[0046] When tube insertion is required, use the guide wire 300 to insert the visual probe 301 into the designated position inside the feeding tube 100. Slowly and gently insert the tip of the feeding tube 100 into the patient's nasal cavity. The patient should cooperate by swallowing. While inserting the tube, the medical staff should observe the image on the handheld monitor 302. When the insertion depth reaches the 40cm mark, observe through the probe 301 whether the tip of the feeding tube 100 is in the stomach. After confirming that it is correct, remove the guide wire 300 and use a syringe to inflate 100-200ml of air through the first interface 501 to slightly expand the stomach cavity. Reinsert the guide wire 300 with the visual probe 301 and continue to insert the tube slowly and gently. When the tube reaches the 70-75cm mark, slow down the speed and pay attention to the feel. Observe whether the handheld monitor 302 shows the position at the pylorus. Continue to advance the tube. When there is a clear breakthrough feeling, it has entered the duodenum, and the tube insertion is successful. The recommended insertion depth is 80-100cm.

[0047] When gastric contents need to be decompressed, the second interface 502 can be connected to the negative pressure drainage box to decompress;

[0048] The third interface 503 is connected to the main feeding tube 100 for backup, and is equipped with a guide wire 400. If necessary, the main guide wire 300 can be inserted into the feeding tube 100 together with the guide wire 400 to increase the support of the feeding tube 100 and facilitate tube insertion. When the feeding tube 100 is blocked and needs to be cleared, the first interface 501 and the third interface 503 can be used together to increase the success rate of clearing the tube.
