Description

Technical Field

[0001] The utility model relates to the technical field of sputum suction devices, in particular to a sputum suction device for children's respiratory tract. Background Art

[0002] Suctioning with a sputum suction device is one of the common ways to assist in expectoration. Through negative pressure, the sticky sputum in the lungs can be sucked out as quickly as possible, clearing the patient's respiratory secretions, preventing complications such as suffocation and aspiration pneumonia, improving lung ventilation, and promoting respiratory function. When patients are unable to expectorate on their own, especially infants and critically ill patients, a sputum suction device can be used to suck out the sputum in the lungs, which can improve the patency of the respiratory tract and reduce adverse stimulation of the respiratory mucosa.

[0003] In the prior art, a suction tube is generally inserted into the appropriate part of the patient's mouth to perform suction operations. However, for some children, due to their poor self-control ability, they may feel uncomfortable during the suction process and may subconsciously bite the tube or engage in resistance behaviors, which is not conducive to the smooth progress of the suction work. In view of this, in-depth research was conducted on the above-mentioned issues, which led to the present case. Utility Model Content

[0004] The utility model aims to provide a respiratory tract sputum suction device for children, so as to solve the problem in the above-mentioned background technology that when suctioning sputum for children, the children may bite the tube involuntarily due to discomfort.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example: See Figure 1-4 The pediatric respiratory tract suction device comprises a liquid storage bottle 7, a longitudinal valve cylinder 9 is installed at the top of the liquid storage bottle 7, and a transverse valve cylinder 8 is installed at the top of the longitudinal valve cylinder 9, a sputum suction tube 1 is installed on one side of the transverse valve cylinder 8, and an oral support block 2 is arranged on the outside of the sputum suction tube 1, a through hole 16 is penetrated inside the oral support block 2, and the sputum suction tube 1 penetrates inside the through hole 16, a baffle 13 is installed at one end of both sides of the oral support block 2, and a U-shaped cavity 22 is opened inside the oral support block 2, and the cavity Two rotating cylinders 14 are installed at the bottom of the cavity 22 through a rotating shaft, and the top of the rotating cylinder 14 is provided with a cylindrical groove 20. Two moving blocks 19 are slidably installed inside the cavity 22, and the bottom of the moving blocks 19 are fixed with mounting rods 15, and the bottom ends of the mounting rods 15 extend to the inside of the cylindrical groove 20. A support plate 17 is provided above the oral support block 2, and two connecting rods 18 are fixed at the bottom end of the support plate 17, and the two connecting rods 18 are respectively connected to the tops of the two moving blocks 19;

[0021] A rod cylinder 10 is installed at one end of the transverse valve cylinder 8, and a handle 12 is fixed at one end of the rod cylinder 10. A piston rod 11 is arranged inside the rod cylinder 10, and one end of the piston rod 11 extends to the inside of the handle 12.

[0022] The top end of the support plate 17 and the bottom end of the oral support block 2 are both bonded with a silicone soft pad;

[0023] The inner wall of the cylindrical groove 20 is provided with an internal thread, and the inner wall of the mounting rod 15 is provided with an external thread matching therewith;

[0024] Specifically, Figure 1 and Figure 2 As shown, when using the device, the oral support block 2 is placed inside the child's oral cavity, and the child's oral cavity wraps around the two baffles 13. At this time, the two rotating cylinders 14 are rotated, causing the mounting rod 15 to move in a directional manner under the guidance of the moving block 19, thereby causing the distance between the support plate 17 and the oral support block 2 to change, so that under the premise of ensuring comfort, the silicone pads above the support plate 17 and below the oral support block 2 can press against the patient's upper and lower teeth, thereby propping up the patient's teeth and keeping the mouth open. As the patient's upper and lower teeth separate, the patient's lips are retracted on both sides to limit the baffle 13 from falling off. In this way, the patient will not bite the sputum suction tube 1 again in the future, and the sputum suction tube 1 can also smoothly enter the patient's oral cavity through the through hole 16. By repeatedly pulling and pulling the piston rod 11, negative pressure can be generated to suck out the sputum.

[0025] The outer walls of the two rotating cylinders 14 are fixed with sprockets 24, and the outer walls of the two sprockets 24 are sleeved with chains 23. A fixing ring 25 is installed at one end of the oral support block 2, and a rotating block 26 is arranged on the inner wall of the fixing ring 25. A transmission rod 27 is fixed at one end of the rotating block 26, and one end of the transmission rod 27 extends to the inside of the cavity 22. A bevel gear 21 is installed at the outer wall of one rotating cylinder 14 and one end of the transmission rod 27, and the two bevel gears 21 are meshed with each other.

[0026] The diameter of the rotating block 26 is equal to the inner diameter of the fixed ring 25, and the fixed ring 25 and the rotating block 26 are connected in a rotating manner. A special-shaped groove is provided at one end of the rotating block 26 away from the transmission rod 27.

[0027] Specifically, Figure 2 and Figure 3 As shown, the rotating block 26 can be rotated by cooperating with the special-shaped groove with the help of a tool, and the bevel gear 21 connected to it is driven to rotate through the transmission rod 27, so that the rotating cylinder 14 with the bevel gear 21 installed on the outer wall is rotated by the cooperation of the two bevel gears 21. The rotation of the rotating cylinder 14 will cause the other rotating cylinder 14 to rotate at the same speed through the cooperation of the sprocket 24 and the chain 23. There is a certain friction between the rotating block 26 and the fixed ring 25, and there is no obvious fulcrum except the special-shaped groove, so it will not shift easily at ordinary times.

[0028] A bottom plate 6 is detachably mounted on the bottom end of the liquid storage bottle 7, and a clamping plate 5 is arranged at one end of the bottom end of the bottom plate 6, a threaded rod 4 is mounted at the middle position of one end of the top end of the clamping plate 5 through a rotating shaft, and fixing rods 3 are fixed on both sides of one end of the top end of the clamping plate 5, and the top ends of the fixing rods 3 and the threaded rods 4 extend to the top of the bottom plate 6, the connection between the fixing rods 3 and the bottom plate 6 is a sliding connection, and the connection between the threaded rods 4 and the bottom plate 6 is a threaded connection;

[0029] Specifically, Figure 1 As shown, when in use, the base plate 6 can also be placed on the edge of the table top, and the clamping plate 5 can be kept under the table top, and then the threaded rod 4 can be rotated to cause the clamping plate 5 to move in a directional manner under the cooperation of the fixed rod 3 and the base plate 6. The clamping plate 5 and the base plate 6 cooperate to clamp the edge of the table top, thereby completing the position fixation of the liquid storage bottle 7. In this way, the device as a whole is more stable, and in the subsequent process of pulling out the piston rod 11, it is not easy to cause the suction tube 1 to shake, thereby improving the comfort of the child.

[0030] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
