Description

Technical Field

[0001] This utility model relates to the technical field of medical devices, and in particular to a connector between a metal cannula and an artificial nose. Background Technology

[0002] Currently, clinically used airway humidification methods are divided into two main categories: traditional humidification methods and novel humidification methods. Traditional humidification methods are further divided into intermittent infusion and continuous infusion.

[0003] The drawback of intermittent infusion is that it is difficult to control the amount and rate of humidification fluid, which can easily cause patients to cough or experience airway mucosal bleeding, thus affecting the patient's recovery process.

[0004] Continuous infusion uses a micro-pump to continuously pump in a constant-temperature humidifying solution, providing humidification fluid that meets the body's needs. While continuous infusion ensures a uniform infusion rate, prolonged pumping can cause the fluid to flow asymmetrically along the airway, leading to over-perfusion of one lung segment. Areas that are not adequately humidified may develop thick sputum, which can actually increase the risk of infection.

[0005] An artificial nose is a heat and moisture exchanger. When placed on an artificial airway, it can trap heat and moisture from exhaled air and warm and humidify inhaled air, making the air entering the lower respiratory tract through the artificial nose more in line with the body's needs.

[0006] However, the connection port of the artificial nose does not match the connection port of the metal cannula. The outer diameter of the connection port of the metal cannula is smaller than that of the connection port of the artificial nose. Patients wearing metal cannulas cannot connect the artificial nose to the metal cannula to continuously humidify the airway. Utility Model Content

[0007] One objective of this invention is to provide a connector for a metal sleeve and an artificial nose, which facilitates the connection of the artificial nose to the metal sleeve and enables continuous humidification of the airway.

The width of one end of the elastic adjustment band along its length is smaller than the width of the other end. Each end of the tension adjustment belt has a connecting hole, and the outer wall of the tension adjustment belt has a connecting protrusion that passes through the corresponding connecting hole. The connecting protrusion is interference-fitted with the connecting hole.

[0034] The connector between the metal sleeve and the artificial nose according to an embodiment of the present invention is described in detail below with reference to the accompanying drawings.

[0035] Reference Figure 1-4The connector between the metal sleeve and the artificial nose includes a connecting tube 1. One end of the connecting tube 1 is fitted outside the connection port of the metal sleeve and is press-fitted with the outer wall of the connection port of the metal sleeve. The other end of the connecting tube 1 is fitted outside the connection port of the artificial nose and is press-fitted with the outer wall of the connection port of the artificial nose. The connecting tube 1 is made of silicone.

[0036] A tension adjustment band 2 is provided at one end of the connecting pipe 1 that is connected to the metal sleeve. The tension adjustment band 2 is wrapped around the outer circumference of the connecting pipe 1 and tightens the connecting pipe 1 and the metal sleeve.

[0037] The two ends of the tension adjustment band 2 are arranged to cross each other along its length. One end of the tension adjustment band 2 along its length has a through hole 21 for the other end of the tension adjustment band 2 to pass through. The width of one end of the tension adjustment band 2 along its length is smaller than the width of the other end.

[0038] The tension adjustment band 2 has a connecting hole 22 at both ends along its length. A connecting protrusion 23 passes through the corresponding connecting hole 22 on the outer wall of the tension adjustment band 2, and the connecting protrusion 23 is press-fitted with the connecting hole 22. The tension adjustment band 2 is made of silicone.

[0039] Each connection hole 22 corresponds to at least two connection protrusions 23. In this embodiment, each connection hole 22 corresponds to three connection protrusions 23, which is convenient to adapt to metal sleeve connection ports of different sizes.

[0040] The connecting protrusion 23 includes a fixing part 231 and a limiting part 232. The fixing part 231 is fixedly connected to the tension adjustment band 2, and the limiting part 232 is fixedly connected to the end of the fixing part 231 away from the tension adjustment band 2. The size of the fixing part 231 is the same as the size of the connecting hole 22, and the size of the limiting part 232 is larger than the size of the connecting hole 22. The connecting protrusion 23 is umbrella-shaped.

[0041] The four sides of the fixing part 231 are all rounded, and the four corners of the connecting hole 22 are also rounded and adapted to the shape of the fixing part 231. The four side walls of the limiting part 232 are all arc-shaped, and the four sides of the limiting part 232 are also rounded. This reduces the possibility of the connecting hole 22 being damaged or cracked.

[0042] The tension adjustment band 2 is also provided with clearance holes 24 at both ends along its length. When the connecting protrusion 23 passes through the corresponding connecting hole 22, the clearance hole 24 allows the other connecting protrusion 23 to pass through the connecting hole 22, thus preventing the connecting protrusion 23 that has not passed through the connecting hole 22 from lifting the tension adjustment band 2 and thus preventing the connecting protrusion 23 from coming off the connecting hole 22.

[0043] A positioning strip 3 is provided at the tension adjustment band 2. The two ends of the positioning strip 3 in the length direction are fixedly connected to the outer wall of the connecting pipe 1. The tension adjustment band 2 passes through the middle of the positioning strip 3, so that the tension adjustment band 2 can be positioned on the connecting pipe 1.

[0044] After crossing the two ends of the tension adjustment band 2, the appropriate connecting protrusion 23 is passed through the corresponding connecting hole 22, so that the fixing part 231 is located inside the connecting hole 22 and the limiting part 232 passes through the outside of the tension adjustment band 2, so that the tension adjustment band 2 tightens the connecting pipe 1 and the metal sleeve.

[0045] A sealing plug 4 is provided at the end of the connecting pipe 1 away from the metal sleeve. The sealing plug 4 is press-fitted with the inner wall of the end of the connecting pipe 1 away from the metal sleeve. The sealing plug 4 is made of silicone.

[0046] A fixing strip 5 is provided on the outer wall of the end of the connecting pipe 1 away from the metal sleeve. A positioning protrusion 51 is provided on the end of the fixing strip 5 away from the connecting pipe 1. A positioning hole 41 is provided on the sealing plug 4 for the positioning protrusion 51 to pass through. The fixing strips 5 are symmetrically arranged on both sides of the radial direction of the connecting pipe 1, and each fixing strip 5 corresponds to one positioning protrusion 51. The positioning hole 41 corresponds one-to-one with the positioning protrusion 51.

[0047] When the artificial nose is not needed, the sealing plug 4 is placed on the end of the connecting tube 1 corresponding to the artificial nose, and the positioning protrusion 51 is inserted into the positioning hole 41 to seal the end of the connecting tube 1 away from the metal sleeve.

[0048] The implementation principle of the connector between a metal sleeve and an artificial nose in this application embodiment is as follows: Place one end of the connecting tube 1 with the tension adjustment band 2 onto the connecting tube 1, and then tighten the connecting tube 1 and the metal sleeve with the tension adjustment band 2. When it is necessary to connect the artificial nose, remove the sealing plug 4, put the other end of the connecting tube 1 on the outside of the connection port of the artificial nose and press against the outer wall of the connection port of the artificial nose. This makes it easy to connect the artificial nose to the metal sleeve and can continuously humidify the airway.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
