Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically to a gastrostomy tube balloon. Background Technology
[0002] Currently, in the design of gastrostomy tubes, a balloon structure is usually equipped at the tip to provide fixation and support within the stomach. For example... Figure 1 As shown, a common structural solution is to directly attach the balloon to the side of the double-lumen silicone tube. This structure requires manual bonding by workers, which requires high operational skills and is greatly affected by human factors. The bonding accuracy is limited, and the balloon position is prone to displacement, reducing the fixation and support effect, which in turn affects the safety and stability of the gastrostomy tube in clinical applications. Moreover, due to the uncertainty of manual operation, it is difficult to achieve large-scale, high-efficiency, and stable production. Utility Model Content
[0003] The technical problem this invention aims to solve is that existing gastrostomy tubes suffer from significant human error, which affects their safety and stability in clinical applications and makes large-scale, high-efficiency, and stable production impossible.
[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:
[0005] A gastrostomy tube balloon includes a double-lumen silicone tube, an adhesive portion, and a balloon body. The double-lumen silicone tube includes a feeding chamber and an infusion chamber, which do not interfere with each other. One end of the adhesive portion is fitted into the distal port of the feeding chamber, and the other end of the adhesive portion is connected to one end of the balloon body. The other end of the balloon body is flipped backward and fixedly connected to the outer surface of the double-lumen silicone tube. The balloon body covers the outside of the double-lumen silicone tube to form a cavity. An opening is provided on the double-lumen silicone tube to connect the cavity and the infusion chamber.
[0006] Preferably, the adhesive portion has an annular step near one end of the dual-lumen silicone tube, and the step surface of the annular step abuts against the distal end face of the filling cavity to seal the distal port of the filling cavity.
[0007] Preferably, an adhesive for fixing is provided between the step surface of the annular step and the distal end face of the filling cavity.
[0008] Preferably, the adhesive part is a conical head, and the smaller end of the conical head is connected to one end of the balloon body.
[0009] Preferably, the adhesive part is integrally formed with the airbag body. By making the airbag and the conical front end into an independent whole part, the positioning error that may occur in the traditional two-step bonding is eliminated, making the airbag position more accurate and avoiding the problem of eccentricity.
[0010] Compared with the prior art, the present invention has the following advantages:
[0011] (1) The gastrostomy tube balloon provided in this application includes a double-lumen silicone tube, an adhesive part and a balloon body. The balloon body is connected to the double-lumen silicone tube through the adhesive part. The balloon is flat, which is convenient for clinical use. The adhesive part and the balloon body are integrally formed. The integral parts eliminate the positioning error that may occur in manual bonding, making the balloon position more accurate. The improved bonding accuracy not only ensures that the balloon fixation and support in the stomach is more reliable, but also reduces the risk of complications that may be caused by balloon eccentricity, and improves the safety of clinical use.
[0012] (2) The gastrostomy tube balloon bonding operation provided in this application only requires bonding the whole part to the far end of the silicone tube, without the need for step-by-step operation, reducing the dependence on the operator's technical level, and can realize process automation or semi-automation, further improving production efficiency.
[0013] (3) The adhesive part of the gastrostomy tube balloon provided in this application is integrally formed with the balloon body. The prefabrication and standardized production of the integrated component can significantly shorten the assembly time and improve the overall production capacity and consistency of the production line.

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0019] like Figure 2 and 3As shown, this utility model discloses a gastrostomy tube balloon, including a double-lumen silicone tube, an adhesive part 3, and a balloon body 4. The double-lumen silicone tube includes a feeding chamber 1 and an inflation chamber 2, which do not interfere with each other. One end of the adhesive part 3 is fitted into the distal port of the feeding chamber 1. Preferably, the adhesive part 3 is fixedly connected to the distal port of the feeding chamber 1 by a medical adhesive, such as medical epoxy resin or other adhesive materials that meet national drug regulatory standards.
[0020] The other end of the adhesive portion 3 is connected to one end of the balloon body 4. The other end of the balloon body 4 is flipped backward and fixedly connected to the outer surface of the double-lumen silicone tube. Preferably, the other end of the balloon body 4 is connected to the outer surface of the double-lumen silicone tube using a medical adhesive, such as medical epoxy resin or other adhesive materials that meet national drug regulatory standards. The balloon body 4 covers the outside of the double-lumen silicone tube to form a cavity 5. An opening 6 is provided on the double-lumen silicone tube to connect the cavity 5 and the filling chamber 2. One end of the filling chamber 2 is connected to an external filling device, and the other end is filled into the cavity of the balloon body 4 through the opening 6. The filling device can inflate or inject fluid into the filling chamber 2, causing the balloon body 4 to inflate and provide support.
[0021] like Figure 3 As shown, an annular step 7 is provided at one end of the adhesive part 3 near the dual-lumen silicone tube. The step surface of the annular step 7 abuts against the distal end face of the filling cavity 2 to seal the distal port of the filling cavity 2. An adhesive for fixing is provided between the step surface of the annular step 7 and the distal end face of the filling cavity 2, which can be applied by dispensing.
[0022] like Figure 3 As shown, the adhesive part 3 is a conical head, with the smaller end of the conical head connected to one end of the balloon body 4. The adhesive part 3 is integrally formed with the balloon body. By making the balloon and the conical front end into an independent whole, the positioning error that may occur in the traditional two-step bonding is eliminated, making the balloon position more accurate and avoiding the problem of eccentricity.
[0023] The fabrication steps of a gastrostomy tube balloon are as follows:
[0024] 1. Preparation of the 2-in-1 component:
[0025] The balloon body 4 and the conical head are prepared using suitable medical materials, such as medical-grade silicone or other biocompatible materials. The balloon body 4 and the conical head are integrally molded during the production process using methods such as injection molding or thermoforming, thereby ensuring consistency in their size, shape, and relative position.
[0026] 2. Pretreatment and bonding preparation:
[0027] The two-in-one component and the distal end of the feeding chamber 1 are subjected to surface treatment, such as plasma treatment or chemical activation, to improve the adhesion of the adhesive. A suitable medical adhesive, such as medical epoxy resin or other adhesive materials that meet national drug regulatory standards, is selected in advance.
[0028] 3. Bonding process:
[0029] The pre-treated two-in-one component is accurately positioned at the distal end of feeding chamber 1 and bonded using automated equipment. The equipment's built-in positioning device ensures that the center of the two-in-one component is aligned with the axis of the silicone tube, preventing misalignment. The bonding process is completed under strictly controlled temperature, humidity, and curing time.
[0030] Specifically, the steps include the following:
[0031] Step 1: As Figure 2 As shown, the anterior segment of the adhesive balloon is bonded, and the adhesive part 3 is fixedly connected to the feeding cavity 1 by medical adhesive;
[0032] Step 2: As Figure 3 As shown, the other end of the balloon body 4 is flipped backward, and the balloon body 4 is bonded to the outer surface of the double-lumen silicone tube and then covered to the outside of the double-lumen silicone tube to form a cavity 5.
[0033] 4. Curing and quality inspection:
[0034] After bonding, a suitable curing process, such as heat curing or UV curing, is used to ensure that the adhesive is completely cured and forms a stable adhesive layer. After curing, an automatic detection system is used to check the installation accuracy of the balloon relative to the silicone tube to ensure that the product meets the design requirements. The detection items include balloon position, angular deviation, and adhesion strength.
[0035] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
