Description

Technical Field

[0001] The utility model belongs to the technical field of nasogastric tubes, and in particular relates to a nasogastric tube with wax oil lubricant. Background Art

[0002] In current nursing work, the use of nasogastric tubes is very common. However, traditional nasogastric tubes may encounter resistance during insertion, increase the patient's discomfort, and may even cause intubation failure. At present, paraffin oil is routinely used in clinical practice for lubrication before intubation, but the paraffin oil used in clinical practice is in bottles of different volumes. Large bottles of paraffin oil are prone to contamination due to repeated use. If small bottles of paraffin oil are used, it is necessary to pour the paraffin oil onto the tip of the nasogastric tube before intubation during the nursing operation, which is inconvenient to operate. Therefore, it is necessary to provide an improved nasogastric tube to improve the success rate of intubation and reduce the patient's discomfort. Utility Model Content

[0003] In response to the above-mentioned problems in the prior art, the present application proposes a nasogastric tube with wax oil lubricant. By putting a lubricating device with built-in wax oil lubricant on the local part of the nasogastric tube, the lubrication operation of the nasogastric tube is made more convenient.

[0004] The utility model proposes a nasogastric tube with wax oil lubricant, comprising an outer packaging bag, a nasogastric tube body and a lubricating device arranged in the outer packaging bag; the lubricating device comprises a sealed lubricant bag and a wax oil lubricant pre-filled in the lubricant bag; the lubricant bag is a semi-circular tubular bag structure with an opening on one side, and the lubricant bag is sleeved on the outer wall of the nasogastric tube body; the arc-shaped inner end surface of the lubricant bag contacts the outer wall of the nasogastric tube body, and the inner end surface of the lubricant bag or the end surface located at the opening is provided with a through hole and a sealing film that closes the through hole.

[0005] Furthermore, a plurality of through holes are arranged at intervals along the length direction of the lubricant bag.

[0006] Furthermore, the through holes are distributed on the end surfaces on both sides of the opening of the lubricant bag.

[0007] Furthermore, the arc-shaped outer end surface of the lubricant bag is also provided with a gripping portion.

[0008] Furthermore, the gripping portion comprises a finger sleeve; the bottom of the finger sleeve is bonded and fixed to the outer end surface of the lubricant bag, and the finger sleeve is provided with a channel penetrating along the circumferential direction of the lubricant bag.

[0009] Furthermore, there are two finger sleeves, which are distributed on both sides of the opening of the lubricant bag.

[0010] Furthermore, the sealing film is connected to the lubricant bag by electrostatic adsorption.

[0011] The beneficial effects of the utility model are as follows: by sleeve-mounting the lubricating device on the outer wall of the nasogastric tube body and placing them together in the outer packaging bag, the sealing film is torn to release the sealing of the through hole of the lubricant bag, so that the wax lubricant in the lubricant bag overflows from the through hole, the lubricant bag is slid along the length direction of the nasogastric tube body, and the wax lubricant overflowing from the through hole can synchronously lubricate the nasogastric tube body, the lubrication operation of the nasogastric tube body is very simple, and the semi-circular lubricant bag has a large contact surface with the outer wall of the nasogastric tube body, and the lubrication effect is good. Compared with the traditional method of transferring paraffin oil to the nasogastric tube through gauze and then applying lubrication, the efficiency of the lubrication operation is greatly improved.

[0019] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] like Figure 1-Figure 6 The nasogastric tube with wax lubricant shown includes an outer packaging bag 1 and a nasogastric tube body 2 and a lubricating device 3 arranged in the outer packaging bag 1; when the nasogastric tube body 2 and the lubricating device 3 are placed in the outer packaging bag 1, they should be handled in a sterile environment to ensure the cleanliness of the outer packaging bag 1.

[0021] The lubricating device 3 comprises a sealed lubricant bag 4 and a wax oil lubricant 5 pre-filled in the lubricant bag 4 .

[0022] like Figure 2 As shown, the lubricant bag 4 is a semicircular tubular bag structure with an opening on one side. The lubricant bag 4 can be made of plastic or rubber.

[0023] The lubricant bag 4 is sleeved on the outer wall of the nasogastric tube body 2. Since the nasogastric tube body 2 is a round tube, the lubricant bag 4 is a semi-circular tube. The lubricant bag 4 can be sleeved on the nasogastric tube body 2 through its opening. Figure 1 shown.

[0024] After the lubricant bag 4 is mounted on the nasogastric tube body 2, the arc-shaped inner end surface of the lubricant bag 4 contacts the outer wall of the nasogastric tube body 2. In other words, the diameter of the arc-shaped inner end surface of the lubricant bag 4 is designed to be specific according to the diameter of the nasogastric tube body 2. The inner end surface of the lubricant bag 4 or the end surface at the opening is provided with a through hole 8 and a sealing film 9 for closing the through hole 8. In this embodiment, Figure 5 As shown, the through holes 8 and the sealing film 9 are distributed on the end faces on both sides of the opening of the lubricant bag 4, and a plurality of through holes 8 are arranged at intervals along the length direction of the lubricant bag 4. The sealing film 9 is connected to the lubricant bag 4 by electrostatic adsorption. Of course, the sealing film 9 can also be bonded to the lubricant bag 4. When the sealing film 9 is torn off, the wax oil lubricant 5 in the lubricant bag 4 overflows through the through holes 8. Of course, if the overflow speed is to be increased, a certain pressure can be applied to the lubricant bag 4. In addition, since there are multiple through holes 8, the number of through holes 8 to be unsealed can be adjusted by controlling the tearing length of the sealing film 9, thereby controlling the overflow amount of the wax oil lubricant 5.

[0025] In order to make the lubrication operation more convenient, the arc-shaped outer end surface of the lubricant bag 4 is also provided with a gripping portion 6. In this embodiment, the gripping portion 6 includes a finger sleeve; the bottom of the finger sleeve is bonded and fixed to the outer end surface of the lubricant bag 4, and a channel 7 that runs through the circumference of the lubricant bag 4 is provided on the finger sleeve. There are two finger sleeves, which are distributed on both sides of the opening of the lubricant bag 4. When in use, first tear off the sealing film 9, and ensure that the lubricant bag 4 is sleeved on the nasogastric tube body 2, and then insert the fingers into the channels 7 of the two finger sleeves respectively. Since the finger sleeves are distributed on both sides of the opening of the lubricant bag 4, the fingers in the two finger sleeves can squeeze the lubricant bag 4, and control the squeezing force, and control the overflow amount of the wax lubricant 5 in the lubricant bag 4. In addition, the fingers in the finger sleeves move along the length direction of the nasogastric tube body 2, which can drive the lubricant bag 4 to move accordingly, so as to achieve lubrication of the outer wall of the nasogastric tube body 2. In some embodiments, the gripping portion 6 may also be a raised ear piece, and the lubricant bag 4 is operated to slide along the length direction of the nasogastric tube body 2 by pinching the ear piece with fingers.

[0026] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of ​​the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
