Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and specifically, to a double-tube intubation fixation device. Background Technique

[0002] The nasogastric nutrition catheter (also known as the nasointestinal tube) made of polymer materials is a medical device that is inserted through the nasal cavity, passes through the pharynx, esophagus, and stomach, and is placed in the duodenum or jejunum, playing an important role in enteral nutrition infusion for patient nutritional support. Using the nasointestinal tube to perfuse nutrient solution through the nasal cavity has become a widely used clinical nursing operation technique. It is an important medical technical means necessary to ensure that patients in a coma, vegetative state, or those who cannot eat orally due to digestive tract diseases such as esophageal cancer, esophageal stricture, laryngeal cancer, hypopharyngeal cancer, etc. can ingest sufficient nutrients during treatment to maintain their physical health.

[0003] Regarding double-tube intubation fixation devices, there are many existing technologies, for example:

[0004] Chinese Patent Publication No. CN219148575U discloses a double-tube intubation fixation device, including a fitting component and a fixing frame arranged on the fitting component. Both ends of the fitting component are connected with connecting parts for fixing the fitting component at the philtrum below the nostrils. The fixing frame includes at least two pressing parts. One side of the two pressing parts is connected to each other, and the other side is detachably connected to each other. A containing part for placing the pipeline is arranged between the two pressing parts.

[0005] It can be seen from this that most double-tube intubation fixation devices include a fitting component. By arranging pressing parts on the fitting component and using the pressing parts to press and fix the pipeline, the fixation of the pipeline is realized. However, since the pressing part is actually composed of a gear and a one-way block, the fixing force on the pipeline is actually only the pressing force on the pipeline. The moving direction of the pipeline in the pressing part is perpendicular to the direction of the pressing force. Therefore, in fact, the factors determining the pipeline fixing effect are jointly determined by the pressing force, the material of the pipeline surface, and the material of the containing part in the pressing part. When the magnitude of the pressing force reaches an appropriate degree for fixing the pipeline, increasing the pressing force on the pipeline will not improve the pipeline fixing effect much.

[0006] In view of this, we propose a double-tube intubation fixation device. Utility Model Content

[0007] The purpose of the present utility model is to provide a double-tube intubation fixation device that can change the angle of the pipeline during fixation to solve the problems raised in the above background technique.

[0008] To achieve the above purpose, the present utility model provides the following technical solutions:

[0009] A double-tube intubation fixation device includes a fixing frame that fits the nostrils. The fixing frame is fixed with a pluggable fixing member for fixing the tube. The fixing member includes a fixing ring with different hole diameters on both sides. One side of the fixing ring is an inclined surface, and the inclined surface of the fixing ring fits the fixing member.

[0010] As a further solution of the present utility model: The fixing frame includes a housing. The housing is provided with an insertion hole, and the insertion hole is symmetrically provided with clamping grooves. The two sides of the fixing ring are symmetrically provided with clamping posts; the clamping posts are clamped in the clamping grooves to limit the movement of the fixing member.

[0011] As a further solution of the present utility model: The smaller hole diameter size of the fixing ring is a, the outer peripheral size of the fixing ring is b, the outer peripheral diameter size of the cross-section of the tube orifice is c, and the hole diameter size of the insertion hole is d. The relationship between the smaller hole diameter size a of the fixing ring and the outer peripheral diameter size c of the cross-section of the tube orifice is a≥c; the relationship between the hole diameter size d of the insertion hole, the outer peripheral size b of the fixing ring, and the smaller hole diameter size a of the fixing ring is a≤d<b.

[0012] As a further solution of the present utility model: The angle range of the inclined surface of the fixing ring is 1° to 5°.

[0013] As a further solution of the present utility model: One side of the insertion hole is provided with a nasal plug, and the nasal plug is provided with a through hole having the same hole diameter size as the insertion hole.

[0014] As a further solution of the present utility model: The two sides of the housing are symmetrically provided with hanging rings for connecting an elastic band to fix the housing.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] 1. In this double-tube intubation fixation device, by setting the hole diameters on both sides of the fixing ring to be different, and the size of the small opening of the fixing ring is equal to the size of the tube orifice. When the tube passes through the large opening of the fixing ring and exits from the small opening, the small opening of the fixing ring is used to preliminarily fix the tube.

[0017] 2. In this double-tube intubation fixation device, by setting the contact surface between the fixing member and the fixing frame as an inclined surface, when the fixing member is fixed on the fixing frame, the vertical axis of the fixing member is not perpendicular to the horizontal section of the fixing frame, and the fixing member bends the tube to achieve the effect of secondary fixation. Using the friction force of the tube at the bending part, it is difficult for the patient to pull out the tube. The overall use is convenient and fast, and the cost is saved at the same time.

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0026] As Figure 1 shown, this embodiment provides a double-tube intubation fixing device, including a fixing bracket 100. Considering that the fixing bracket 100 is fixed at the nostril, therefore, the overall shape of the fixing bracket 100 needs to fit the nostril. The fixing bracket 100 is fixed with a fixing part 200, and the fixing part 200 is used to fix the pipeline. Considering that in actual use, the extraction times of the two tubes are inconsistent, therefore, the fixing part 200 is set to be pluggable and unplugable, which is convenient for medical staff to extract a single pipeline. Considering that it is convenient to pass the pipeline through the fixing part 200, therefore, the fixing part 200 includes a fixing ring 201 with different apertures on both sides, which is convenient for the pipeline to penetrate into the fixing ring 201 from the large opening and exit from the small opening. Considering that the patient may pull the pipeline due to discomfort, therefore, one side of the fixing ring 201 is an inclined surface, and the inclined surface of the fixing ring 201 fits with the fixing part 200, so that the fixing part 200 bends the pipeline, and the friction force of the pipeline at the bending part makes it difficult for the patient to pull out the pipeline.

[0027] The improvement of this embodiment lies in that: by setting the aperture diameters on both sides of the fixing ring 201 to be different, the size of the small opening of the fixing ring 201 is equal to the size of the pipe nozzle. When the pipe passes through the large opening of the fixing ring 201 and exits from the small opening, the small opening of the fixing ring 201 is used to initially fix the pipe. At the same time, the contact surface between the fixing member 200 and the fixing frame 100 is set as an inclined surface. When the fixing member 200 is fixed on the fixing frame 100, the vertical axis of the fixing member 200 is not perpendicular to the horizontal section of the fixing frame 100, and the fixing member 200 bends the pipe to achieve the effect of secondary fixing. By using the friction force of the pipe at the bending part, it is difficult for the patient to pull out the pipe. The overall use is convenient and fast, and the cost is saved at the same time.

[0028] As Figure 2 and Figure 3 shown, further disclosure is made on how the fixing member 200 is fixed in the fixing frame 100. The fixing frame 100 includes a housing 101. The housing 101 is provided with an insertion hole 103, and symmetrically arranged card slots 102 are provided in the insertion hole 103. Symmetrically arranged clamping columns 202 are provided on both sides of the fixing ring 201; the clamping columns 202 are clamped in the card slots 102 to limit the movement of the fixing member 200;

[0029] Considering that the sizes of the pipe, the fixing ring 201, and the insertion hole 103 determine the relationship of socketing with each other. Therefore, the size of the smaller aperture of the fixing ring 201 is a, the outer peripheral size of the fixing ring 201 is b, the outer peripheral diameter size of the pipe nozzle cross-section is c, and the aperture size of the insertion hole 103 is d. The relationship between the size a of the smaller aperture of the fixing ring 201 and the outer peripheral diameter size c of the pipe nozzle cross-section is a≥c; the relationship between the aperture size d of the insertion hole 103, the outer peripheral size b of the fixing ring 201, and the size a of the smaller aperture of the fixing ring 201 is a≤d<b; at the same time, in order to achieve the effect of bending and fixing the pipe, the inclination angle range of the inclined surface of the fixing ring 201 is 1° to 5°.

[0030] As Figure 4 shown, considering that there is still a shaking problem when the pipe is directly inserted into the nasal cavity through the fixing frame 100. Therefore, a nasal plug 104 is provided on one side of the insertion hole 103. The nasal plug 104 is provided with a through hole having the same aperture size as the insertion hole 103. By using the through hole in the nasal plug 104, the pipe is assisted in being limited, so that the pipe is inserted into the nasal cavity more stably. At the same time, the nasal plug 104 fits with the nasal cavity, and it also plays an auxiliary fixing effect on the fixing of the fixing frame 100;

[0031] Considering that the fixing frame 100 is fixed at the nostrils of the patient. Therefore, hanging rings 105 are symmetrically provided on both sides of the housing 101. The hanging rings 105 are used to connect the elastic bands for fixing the housing 101. Through the connection between the hanging rings 105 and the elastic bands, the fixing frame 100 is fixed to prevent the fixing force of the nasal plug 104 from being insufficient and causing the fixing frame 100 to fall off automatically.

[0032] In summary, the working principle of this solution is as follows:

[0033] Insert one end of the pipeline through the large opening of the fixing ring 201 and out through the small opening. Then, slide the fixing member 200 to adjust the position of the fixing ring 201 on the pipeline. Next, insert one end of the pipeline into the insertion hole 103 and pass it through the through-hole of the nasal plug 104. Align the clamping post 202 of the fixing ring 201 with the clamping groove 102 and press it downwards so that the clamping post 202 is clamped in the clamping groove 102 for fixation. The inclined surface of the fixing ring 201 fits with the fixing member 200, resulting in the vertical axis of the fixing member 200 not being perpendicular to the horizontal cross-section of the fixing frame 100. At this time, the fixing member 200 will bend the pipeline to fix it. Insert the nasal plug 104 together with the pipeline into the nasal cavity, then hang the hanging ring 105 on the elastic band and fix the elastic band on the patient's head, thus completing the installation.

[0034] Although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0035] Therefore, the above description is only a preferred embodiment of the present application and is not used to limit the scope of implementation of the present application; that is, all equivalent transformations made according to the scope of the claims of the present application are within the protection scope of the claims of the present application.
