Embodiment 1

[0033] see figure 1 As shown, the present embodiment provides a non-inflatable cuff 10, which includes a balloon body 11, on which a bonding surface 12 for adhesion with the intubation tube body is formed, and the balloon body 11 is filled with gel. The plastic-shaped capsule 11 fits and supports the airway.

[0034] Wherein, the capsule body 11 is provided with a central perforation to form a closed cavity, and the wall surface of the central perforation forms a bonding surface 12. The capsule body 11 is provided with a glue injection port 13, and the gel is injected from the glue injection port 13. The capsule body 11 and Its central perforation and glue injection port 13 are integrally formed by blow molding, and the glue injection port 13 passes through a heat-sealed port.

[0035] The raw materials of the gel include superabsorbent resin, water, jelly, the contents of the ice pack, acrylic or polyacrylamide and other hydrogel materials; the raw materials can be in powder...

Embodiment 2

[0038] see figure 2 As shown, different from the non-replenishable cuff in Example 1, this embodiment provides a non-inflatable cuff 10 that can be refilled, and the capsule body 11 is formed with an adhesive surface for adhesion with the intubation tube body 12. The capsule body 11 is filled with gel, and the gel shapes the capsule body 11 to fit and support the airway.

[0039] Both ends of the capsule body 11 are open and are provided with a fixed edge 14, which is bonded to the intubation tube body, so that the capsule body 11 and the tube wall form a closed cavity, and the tube wall is provided with a plug to supplement the coagulation in the closed cavity. Glue filling port. In this way, the pressure of the cuff on the airway wall can be adjusted to improve the fitting effect with different human airways.

Embodiment 3

[0041] see image 3As shown, on the basis of Embodiment 1, this embodiment provides a multi-capsule non-inflatable cuff 10, an outer bag 15 is arranged outside the aforementioned bag body 11, and adhesive parts are arranged at both ends of the outer bag 15 16 , the adhesive part 16 adheres to the intubation tube body, thereby forming a wrapping around the capsule body 11 .

[0042] The adhesive portion of the outer bag 15 is everted to expose the glue injection port 13 of the capsule body 11 for glue injection. After the glue injection is completed, the glue injection port 13 is closed, and then the adhesive portion is glued and sealed.

[0043] The function of the outer capsule 15 is to protect the capsule body 11 of the inner layer, provide additional protection, prevent oil leakage from the gel, improve the safety of using the cuff, and reduce the probability of complications.

Abstract

The invention discloses an inflation-free sleeve bag and endotracheal cannulas. The inflation-free sleeve bag comprises a bag body; a bonding face used for being bonded with a cannula body is formed on the bag body; the bag body is filled with gel; and the gel is used for shaping the bag body to be attached to and support a trachea. According to the inflation-free sleeve bag, the fluid gel is usedas a filler, the problems that an existing air bag leaks air and is unstable in air pressure are solved, the matching performance of the sleeve bag and the trachea of a human body is improved, the glue supplementing design can be added, and the sealing performance design of the sleeve bag is improved. The invention further discloses the various endotracheal cannulas which adopt the above-mentioned inflation-free sleeve bag; existing products such as endotracheal cannulas, tracheotomic cannulas, double lumen bronchial cannulas and sealing bronchial cannulas are optimized, and clinical use requirements are met.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an inflatable cuff and an airway endotracheal tube. Background technique [0002] At present, the product categories of airway devices on the market mainly include: tracheal intubation, tracheostomy intubation, double-lumen bronchial intubation, and blocked bronchial intubation. They are mainly used by medical staff to anesthetize patients in the operating room or when resuscitating patients in emergency departments and ICU wards, and are used to establish short-term non-deterministic artificial airways for patients. [0003] These existing medical devices all have an inflatable cuff, which is placed in the main trachea and bronchi in the human body to play the role of fixing and sealing the airway. However, in clinical use of this type of cuff, there is slow air leakage or the size of the cuff does not match the physiological structure of the airway of the human body, r...
