Abstract
Description
Technical Field
[0001] The utility model relates to the field of sputum suction tools used for tracheal intubation and percutaneous tracheotomy, in particular to a positioning sputum suction tube and a sputum suction device. Background Art
[0002] Endotracheal intubation is a commonly used clinical operation technique. A special endotracheal tube is inserted into the trachea through the glottis. This operation can ensure effective ventilation and airway patency for patients during surgery, and provide conditions for ventilation and oxygen supply, airway suction, and prevention of aspiration. In most cases, oral endotracheal intubation is superior to nasotracheal intubation and is performed through direct laryngoscopy or video laryngoscopy.
[0003] Percutaneous tracheotomy is a simple, quick and minimally invasive surgical method, which is particularly suitable for the treatment of critically ill patients. This technology uses skin puncture and dilator to insert the tracheal tube. Its main features include less damage, small incision, smooth and beautiful scar, no depression, and less time, so it is often used for emergency airway rescue.
[0004] During surgical procedures such as endotracheal intubation and percutaneous tracheotomy, the patient's spontaneous coughing and expectoration ability is often poor, and there is a high risk of secretions. In particular, patients with craniocerebral trauma, intracranial or peripheral nerve diseases, impaired consciousness, tetanus, inhalation burns, major chest and abdominal surgery, bronchiectasis, chronic pneumonia, laryngeal dysfunction, etc., which reduce or lose the coughing and expectoration functions, will cause a large amount of sputum to accumulate in the trachea. During endotracheal intubation and percutaneous tracheotomy, the sticky sputum in the trachea needs to be sucked out in time. However, the situation of each patient is different, and there are at least the following problems in the suction process:
[0005] 1. Currently, the suction tube can be inserted through a fiber bronchoscope for suction. Since there is a light source in front of the fiber bronchoscope, the insertion position can be confirmed by the light source through the patient's neck. However, the purchase price of fiber bronchoscope is high, so many small hospitals do not have fiber bronchoscopes. Doctors operate based on experience. Although it can also solve the problem of suction, the accuracy of controlling the insertion depth is not enough. Usually, the suction tube cannot be accurately inserted into the location of the sticky sputum at one time. It needs to be repeated many times, and the suction is not thorough.
[0006] 2. When inserting the suction tube based on experience without the aid of a fiberoptic bronchoscope, it is impossible to know whether the inserted suction tube is folded or bent, etc., so it is unknown where the end of the suction tube is;
[0007] 3. The existing sputum suction tube cannot effectively suck out some very viscous solid or jelly-like stubborn sputum. Utility Model Content
[0008] The purpose of the utility model is to solve at least part of the above existing problems.
[0009] In order to solve the above technical problems, the utility model provides a positioning sputum suction tube, comprising:

[0013] A wire, one end of which is connected to the light-emitting element, and the other end of which is connected to the switch and the button battery.
[0014] As a preferred implementation of the positioning sputum suction tube of the utility model, the other end of the tube body has a first mounting groove, and the light-emitting component is located in the first mounting groove.
[0015] As a preferred embodiment of the positioning sputum suction tube of the utility model, the connecting joint has an interface, and the interface has a detachably connected sealing plug.
[0016] The utility model sputum suction device comprises any one of the above described positioning sputum suction tubes, and further comprises:
[0017] A catheter, which is detachably connected to the other end of the tube body in the positioning sputum suction tube; the catheter is at least partially located in the tube body;
[0018] A reciprocating piston is slidably mounted in the conduit; a liquid seal is formed between the reciprocating piston and the conduit; a traction plate is fixedly connected to one side of the reciprocating piston; and the traction plate has a detachably connected traction shaft;
[0019] One end of the catheter outside the tube body is movably connected to two connecting rods, each of which has a fixedly connected clamping spoon at one end and a long sliding hole at the other end, and the long sliding hole is movably connected to the traction shaft.
[0020] As a preferred embodiment of the sputum suction device of the utility model, the end of the catheter outside the tube body has two symmetrical second mounting grooves; each of the second mounting grooves has a first connecting hole that penetrates the second mounting groove;
[0021] The two connecting rods are located in the two second mounting grooves; each of the connecting rods has a second connecting hole, and the second connecting hole and the first connecting hole are located on the same axis;

In addition, the utility model also solves the problem that the currently inserted sputum suction tube cannot be detected when it is folded or bent.
[0051] like Figures 1 to 11 As shown, the utility model sputum suction device comprises:
[0052] a conduit 12, the conduit 12 being detachably connected to the other end of the tube body 1; Figure 1 and Figure 2 The installation effect of the conduit 12 and the pipe body 1 is shown. Figure 4 The decomposition effect of the catheter 12 and the tube body 1 is shown; Figure 5 and Figure 7 As shown, the conduit 12 is at least partially located in the tube body 1;
[0053] Reciprocating piston 13, such as Figure 7As shown, the reciprocating piston 13 is slidably installed in the conduit 12; the reciprocating piston 13 and the conduit 12 are liquid-tight; see Figure 7 and Fig. 9 , one side of the reciprocating piston 13 has a fixedly connected traction plate 14; the traction plate 14 has a detachably connected traction shaft 15;
