Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a tracheal tube blocking device. Background Art

[0002] Tracheotomy is a common medical procedure in which a tracheal tube is inserted after cutting the patient's cervical trachea to relieve dyspnea caused by respiratory dysfunction or retention of lower respiratory tract secretions. During the operation, the respiratory condition needs to be closely observed to ensure smooth airflow. The tube should not be covered with bedding, and secretions coughed out of the tube mouth should be wiped off at any time. It is also necessary to drip or nebulize the trachea regularly and humidify the tube mouth with a single layer of saline gauze. After the operation, the endotracheal tube should be removed and cleaned every 12 to 24 hours. If there is sound or obstruction in the tracheal tube, it must be sucked out at any time or the tracheal tube should be replaced in time, otherwise the tube blockage may be life-threatening.

[0003] The tracheal cannula is a surgical instrument used to treat respiratory diseases, mainly used to solve problems such as tracheal stenosis and dyspnea. It is a soft tubular instrument, usually made of materials such as silicone and polyurethane. Tracheal cannula are divided into two types: internal cannula and external cannula. The internal cannula, also known as the intratracheal tube, is mainly placed inside the trachea to maintain airway patency and avoid airway obstruction. The internal cannula can be made of different materials, diameters and lengths according to the patient's condition. The external cannula, also known as the tracheotomy cannula, is used to keep the airway open after tracheotomy surgery. External cannulas are generally divided into two types: short-term use and long-term use. Short-term external cannulas are mainly used for emergency treatment and temporary treatment, while long-term external cannulas are used for patients with chronic respiratory diseases.

[0004] Most of the existing tracheal intubation kits are composed of three parts: an outer sleeve and a base plate, an inner sleeve and a tube core. For safety reasons, the material is mostly titanium. During the operation, some patients need to perform a tube blocking operation, that is, to block the tube to facilitate intubation of the patient. However, during the operation, the existing inner sleeve has the problem of inconvenience in using the tube. Utility Model Content

The utility model provides a tracheal tube blocking device: comprising a fixing sleeve 101 and an auxiliary component, the auxiliary component comprising an inflatable airbag 102, a T-shaped column 103, a threaded cover 104, a guide tube 105, an air guide tube 106 and a rubber plug 107, and the inflatable airbag 102 is composed of a mounting portion 1021 and an inflatable portion 1022. The above scheme can solve the problem of inconvenience of inner tube blocking during tracheotomy under the prior art. It can be understood that the above scheme can solve the problem of inconvenience of inner tube blocking.

[0019] In this embodiment, the fixing sleeve 101 is used to support the installation of the device installation component.

[0020] Among them, the inflatable airbag 102 is detachably connected to the fixing sleeve 101 and is located in the fixing sleeve 101. The inflatable airbag 102 is composed of a mounting portion 1021 and an inflatable portion 1022. The T-shaped column 103 is slidably connected to the mounting portion 1021 and the fixing sleeve 101 respectively, and is located on the side of the fixing sleeve 101 close to the mounting portion 1021. The threaded cover 104 is threadedly connected to the fixing sleeve 101 and is located on the side of the fixing sleeve 101 close to the T-shaped column 103. The guide tube 105 is detachably connected to the fixing sleeve 101 and is located on the side of the fixing sleeve 101 close to the inflatable airbag 102. The air guide tube 106 is detachably connected to the inflatable airbag 102, slidably connected to the fixing sleeve 101, and is located on the side of the inflatable portion 1022 close to the fixing sleeve 101. The fixing sleeve 101 is provided with an installation cavity for component installation. The outer section of the installation cavity is an internal thread cavity, which is convenient for the installation of the threaded cover 104. The inflatable airbag 102 is composed of a mounting portion 1021 and an inflatable portion 1022. The mounting portion 1021 is convenient for installation and fixation. After the air is introduced into the inflatable portion 1022, it can expand, thereby squeezing the inner sleeve to achieve blocking. A positioning hole is provided on the fixing sleeve 101 to facilitate the insertion of the T-shaped column 103. A circular hole is provided on the mounting portion 1021 to facilitate the passage of the T-shaped column 103. When installing the inflatable airbag 102, first align the mounting hole on the mounting portion 1021 of the inflatable airbag 102 with the mounting hole on the fixing sleeve 101, and then enter and exit the T shaped column 103, 4 T-shaped columns 103 are arranged, further, the threaded cover 104 is tightened to limit the T-shaped column 103, so as to realize the limited installation of the inflatable airbag 102. During installation, one end of the air guide tube 106 needs to be inserted into the connecting air nozzle on the mounting portion 1021 in advance, and the other end passes through the through hole on the fixing sleeve 101 and is connected with the external air control valve. The guide tube 105 is installed on the fixing sleeve 101 by bolts. After the guide tube 105 is installed, the through hole on the end of the horizontal axis thereof is concentric with the central through hole of the inflatable portion 1022 of the inflatable airbag 102, and is also concentric with the central hole of the threaded cover 104, which will be beneficial to the passage of the inner sleeve and the sealing treatment.

[0021] Secondly, the rubber plug 107 is detachably connected to the threaded cover 104 and is located on the side of the threaded cover 104 away from the guide tube 105. The rubber plug 107 is made of non-toxic material, and a countersunk hole is provided on the mounting end surface, which is convenient for locking on the threaded cover 104 by precision screws. After the rubber plug 107 is installed, it is used to protect the inner sleeve.

[0022] Then, the threaded cover 104 has a matching hole 108, which is arranged on the threaded cover 104 and is arranged in a cross shape. The threaded cover 104 is provided with the matching hole 108, which is not arranged through, and is arranged in a cross shape on the end surface of the threaded cover 104. The function of the matching hole 108 is to facilitate the installation and removal of the threaded cover 104.

[0023] Finally, the fixing sleeve 101 has a weight-reducing groove 109, which is annularly arranged on the fixing sleeve 101. A plurality of weight-reducing grooves 109 are annularly arranged on the fixing sleeve 101. The weight-reducing grooves 109 can reduce the processing materials of the fixing sleeve 101 and reduce the cost, and can also reduce the weight of the fixing sleeve 101 itself, making it lightweight and more convenient to take and use.

[0024] When the utility model is used to solve the problem of inconvenience of inner cannula blocking during tracheotomy under the prior art, when it is used first, the inner cannula is passed through the guide tube 105, the inflatable airbag 102, the threaded cover 104 and the rubber plug 107 in sequence, and then the work is carried out. At this time, the through hole of the inflatable airbag 102 can just allow the inner cannula to pass through without squeezing. When blocking is required, the device is moved to the required position, and then air is delivered into the air guide tube 106 through the external air control valve, and then the inflatable airbag 102 is expanded and deformed, and the through hole of the inflatable airbag 102 is closed. Due to the expansion effect, the diameter will be reduced, thereby squeezing the inner sleeve and achieving inner sleeve blocking. During operation, it is only necessary to set the device on the outside of the position of the inner sleeve to be blocked, and then open and close the external air control valve, and inflate the inflatable airbag 102 through the cooperation of the air guide tube 106. As the inflatable airbag 102 expands and deforms, the through hole of the inflatable airbag 102 will be reduced in diameter due to the expansion effect, thereby squeezing the inner sleeve and achieving rapid blocking. The inner sleeve blocking operation is convenient and the blocking is quick, thereby solving the problem of inconvenience of inner sleeve blocking during tracheotomy under the prior art.
