Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an integrated threaded tube for ear, nose and throat surgery. Background Art

[0002] Inhalation anesthesia is a process in which anesthetics are delivered into the patient's alveoli through a mechanical circuit, forming anesthetic gas that diffuses into the blood, thereby inhibiting the central nervous system and anesthetizing the patient.

[0003] Anesthesia machines are used clinically to anesthetize patients. Anesthesia machines deliver anesthetics into the patient's alveoli through a mechanical circuit, forming a partial pressure of anesthetic gas. After diffusing into the blood, it directly inhibits the central nervous system, thereby producing the effect of general anesthesia. Anesthesia machines are semi-open anesthesia devices, which are mainly composed of anesthesia evaporator, flow meter, folding bellows ventilator, anesthesia threaded tube and other components. Anesthetics pass through the anesthesia threaded tube and finally enter the patient's body through an anesthesia mask, tracheal tube or laryngeal mask.

[0004] The anesthesia threaded tube is equipped with a filter to filter gas and prevent infection in patients. Before use, the anesthesia threaded tube, filter and anesthesia mask are separated and need to be assembled when used. However, in ENT surgery, the entire sterile drape must completely cover the patient's head and face, which often causes the joints to fall off easily, causing hypoxia in the patient.

[0005] Patent CN218980139U discloses an integrated anesthesia machine threaded tube with a filter, which does not need to be disassembled, packaged or assembled, effectively reducing the workload of anesthesiologists and improving work efficiency. However, the filter is a disc-shaped structure with a large volume and a short joint. During ENT surgery, the filter and the anesthesia threaded tube will bulge and block the ENT surgeon's surgical operation, hindering the doctor's observation and operation, and affecting the surgery.

[0006] Therefore, how to make the filter achieve the filtering function without affecting the doctor's observation and operation during ENT surgery has become an urgent problem to be solved. Utility Model Content

[0007] In order to prevent the filter from affecting the doctor's observation and operation during ENT surgery, the utility model provides an integrated threaded tube for ENT surgery, uses an extension tube to keep the filter away from the surgical area, and uses an integrated design to reduce the workload of medical staff. The specific technical solution is as follows:

[0008] The threaded tube used for ear, nose and throat surgery comprises an anesthesia threaded tube, a filter and an endotracheal tube joint which are connected in sequence, and an extension tube is arranged between the filter and the endotracheal tube joint.

[0009] Preferably, the extension tube is detachably connected to the filter via a conical joint.

[0010] Preferably, the anesthesia threaded tube, the filter and the conical connector are integrally connected.

[0011] Preferably, a knob joint is connected to one side of the conical joint, and the conical joint is detachably connected to the extension tube via the knob joint.

[0012] Preferably, the extension tube is a threaded telescopic tube, a storage tube is sleeved on the outer side of the knob joint, one side of the storage tube extends toward the tracheal tube, and the extension length is greater than the minimum length of the extension tube.

[0013] Preferably, the side of the storage tube close to the tracheal tube matches the tracheal tube connector.

[0014] Preferably, the outer diameter of the tracheal tube connector is smaller than the inner diameter of the storage tube, and a protrusion is circumferentially arranged on the outer side of the tracheal tube connector.

[0015] Preferably, the main body of the extension tube is made of polypropylene.

[0016] Preferably, the connecting section at the end of the extension tube is made of polyvinyl chloride.

[0017] Beneficial effects:

[0018] The beneficial effects produced by adopting the technical solution of the utility model are as follows:

[0019] 1. An extension tube is provided between the filter and the endotracheal tube connector, which is used during ENT surgery to keep the filter away from the surgical area and provide space for the doctor's observation and operation;

[0020] 2. The extension tube is a threaded telescopic tube. A storage tube is sleeved on the outside of the knob joint. One side of the storage tube extends toward the tracheal tube. The extension length is greater than the minimum length of the extension tube. Under normal conditions, the storage tube is buckled with the tracheal tube joint, and the telescopic tube is compressed in the storage tube to reduce interference with the medical staff's operation. When ENT surgery is required, open the storage tube, lengthen the extension tube, and keep the filter away from the operating area to provide space for the doctor's observation and operation.
