Description

Technical Field

[0001] The present application belongs to the technical field of medical equipment, and specifically relates to a medical device for preventing gastric tube from falling off. Background Art

[0002] In medical practice, gastric tubes (nasogastric tubes, orogastric tubes, nasogastric tubes) are commonly used medical equipment for some patients with severe illnesses who need bed rest. In the prior art, when using gastric tubes, they usually need to be left in place, but because the gastric tubes are easy to fall off, they usually need to be fixed to the side of the patient's nasal cavity with the help of adhesive tape, string, etc. (the fixing method is usually adhesive tape fixing method, double ear hanging fixing method, etc.).

[0003] However, actual clinical statistics show that due to the patient's mood swings, sweat, skin oil secretion and other reasons, the probability of the gastric tube falling off is still high even after fixation, and because some patients' skin is allergic to medical tape, therefore, improving the device to ensure that the gastric tube can be stably fixed on the patient's head and face is of great technical significance for improving the relevant medical care effects. Summary of the invention

[0004] The purpose of this application is to provide a medical gastric tube prevention device for fixing the gastric tube in clinical medical care, thereby laying a certain technical foundation for improving patient care effects.

[0005] The technical solution adopted in this application is described in detail as follows.

[0006] A medical device for preventing a gastric tube from falling off, the device comprising two structural components: a gastric tube buckle and a pressure-sensitive adhesive tape;

[0007] The pressure-sensitive adhesive tape is generally "H"-shaped, and consists of two vertical long arms (the widths of the two vertical long arms are not necessarily the same, and can be appropriately distinguished and adjusted according to the facial structure characteristics of the human body) and a horizontal short arm connecting the two vertical long arms;

[0008] The outer layer is made of transparent breathable material, which makes it easier for the patient's skin surface to breathe and ventilate during application, thus helping to reduce skin allergies.

[0009] Its inner layer is a transparent adhesive composite layer, which is used to adhere to the patient's skin surface; the adhesive composite layer is added with an adsorbent material and a color indicator material; the grease adsorbent material is used to absorb the sweat and grease secreted by the patient's skin surface during the use of the anti-gastric tube falling device, thereby improving the comfort of the device during use; when the adsorption degree of the adsorbent material is saturated, the color of the color indicator material will change significantly (when the adsorption is saturated, the color indicator material will combine with the further adsorbed sweat water to form a gel, so that the original transparent color of the adhesive composite layer is changed to an obvious indicator color), thereby prompting medical staff to replace the relevant fixing pressure-sensitive tape material in time, thereby ultimately improving the comfort of the patient during the use of the gastric tube;

[0010] The specific specifications can be designed as follows: the width of the two vertical long arms can be designed to be 1.5~2cm, and the length can be designed to be 6cm; the length and width of the horizontal short arms can both be designed to be 1.5cm;

[0011] The gastric tube buckle is composed of two flaps connected at the bottom and openable at the top; an adhesive layer is provided at the bottom of the flap connection to facilitate bonding and fixing to the surface of the pressure-sensitive tape;

[0012] A semicircular stomach tube accommodating cavity is provided at the closed upper part of each card flap, and the inner diameter of the accommodating cavity formed after the two card flaps are closed is compatible with the outer diameter of the stomach tube, so as to facilitate the fixation of the stomach tube during use;

[0013] In the preferred design, the inner wall of each semicircular stomach tube accommodating cavity is designed with structures such as threads, teeth or spots to increase the friction between the accommodating cavity and the stomach tube during the process of fixing the stomach tube, thereby better ensuring the fixing effect;

[0014] In a further preferred design, the card flap is designed to be butterfly-wing-shaped, thereby facilitating the opening and closing of the buckle.

[0015] When applying specifically, the application method is as follows:

[0016] After the gastric tube comes out of the patient's nasal cavity, it is first fixed with pressure-sensitive tape (that is, the gastric tube is fixed to the patient's facial skin surface with pressure-sensitive tape. The "H"-shaped pressure-sensitive tape structure design can be better adhered to the patient's nasal cavity, thereby reducing the contact area between the tape and the patient's skin and reducing the occurrence of allergies. Of course, it can also be adhered to other head and facial positions according to the needs of the fixed position); then, the gastric tube that has been fixed once is wrapped from the bottom of the "H"-shaped pressure-sensitive tape to the buckle, and the gastric tube is fixed for a second time with the buckle fixed on the surface of the pressure-sensitive tape.

[0017] In general, the medical anti-gastric tube falling-off device provided by the present application has an ingenious structural design, and is beautiful and practical. It can play a good role in fixing the gastric tube during use, and has positive technical significance for reducing the discomfort of patients receiving enteral nutrition, intragastric treatment, etc. during the use of the gastric tube. At the same time, the relevant preliminary application statistics show that compared with the gastric tube falling-off rate of about 25% in the prior art, after adopting the anti-gastric tube falling-off device of the present application, the gastric tube falling-off rate can be greatly reduced to about 5%. Since the relevant device has a low production cost and a good patient application effect, it has a good significance for production, promotion and application. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present application is further explained below with reference to the embodiments.

[0021] Example 1

[0022] like Figure 1 , Figure 2 As shown, the medical gastric tube prevention device provided by the present application includes two structural components: a gastric tube buckle and a pressure-sensitive tape;

[0023] The pressure-sensitive adhesive tape is composed of two vertical long arms 1 (the widths of the two vertical long arms 1 are not necessarily the same, and can be appropriately distinguished and adjusted according to the facial structure characteristics of the human body) and a horizontal short arm 2 connecting the two vertical long arms 1, and is generally "H"-shaped;

[0024] The outer layer 6 is made of a transparent breathable material, so that the patient's skin surface can breathe and ventilate during application, thereby helping to reduce the occurrence of skin allergies.

[0025] The inner layer 7 is a transparent adhesive composite layer, which is used to adhere to the patient's skin surface; the adhesive composite layer is added with an adsorbent material and a color indicator material; the grease adsorbent material is used to absorb the sweat and grease secreted by the patient's skin surface during the use of the anti-gastric tube falling device, thereby improving the comfort of the device during use; when the adsorbent material has a saturated adsorption degree, the color of the color indicator material will change significantly (when the adsorption is saturated, the color indicator material will combine with the further adsorbed sweat water to form a gel, so that the original transparent color of the adhesive composite layer is changed to a clear indicator color), thereby prompting medical staff to replace the relevant fixing pressure-sensitive tape material in time, thereby ultimately improving the comfort of the patient during the use of the gastric tube;

[0026] In actual products, the surface of the inner layer 7 is provided with a non-stick layer 8 for easy separation, for example, usually made of a transparent plastic material, so as to protect the inner layer before it is actually attached to the skin surface;

[0027] In actual preparation, the existing 3M medical tape can be referred to, and the preparation can be obtained by adding nano-scale hydrocolloid material and adding a breathable layer to its formula;

[0028] The specific specifications can be designed as follows: the width of the two vertical long arms 1 can be designed to be 1.5~2cm, and the length can be designed to be 6cm; the length and width of the horizontal short arm 2 can both be designed to be 1.5cm;

[0029] The stomach tube buckle is composed of two flaps 3 connected at the bottom and openable at the top; an adhesive layer is provided at the bottom of the flap connection to facilitate bonding and fixing to the surface of the pressure-sensitive tape;

[0030] A semicircular stomach tube accommodating cavity 4 is provided at the closed upper part of each card flap, and the inner diameter of the accommodating cavity formed after the two card flaps are closed is compatible with the outer diameter of the stomach tube, so as to facilitate the fixation of the stomach tube during use;

[0031] In the preferred design, the inner wall of each semicircular stomach tube accommodating cavity is designed with structures such as threads, teeth or spots (not shown in detail in the figure, and those skilled in the art can design according to conventional methods) to increase the friction between the accommodating cavity and the stomach tube during the process of fixing the stomach tube, thereby better ensuring the fixing effect;

[0032] In a further preferred design, the card flap is designed to be butterfly-wing-shaped, thereby facilitating the opening and closing of the buckle.

[0033] When using it, the reference method of application is as follows: after the gastric tube comes out of the patient's nasal cavity, first use pressure-sensitive tape to fix it once (that is, use pressure-sensitive tape to stick and fix the gastric tube to the patient's facial skin surface. When using it, first stick one vertical long arm of the pressure-sensitive tape to the skin surface (the other vertical long arm is temporarily not sticky to facilitate subsequent fixation of the gastric tube). Then, wrap the gastric tube from the horizontal short arm of the "H"-shaped pressure-sensitive tape to the buckle after the first fixation, and use the buckle fixed on the surface of the pressure-sensitive tape to fix the gastric tube for a second time, and at the same time firmly stick the other vertical long arm to the patient's skin surface.
