Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an auxiliary device for executing an LP blowing method in a TCD foaming experiment. Background Art

[0002] Clinically, the transcranial Doppler ultrasound (TCD) bubble test can be used to diagnose right-to-left shunt (RLS). Studies have shown that performing a modified Valsalva maneuver (expiratory pressure controlled at 40 mmHg for 10 seconds) during the TCD bubble test can increase the positive detection rate of RLS. Currently, the "LP puffing method" (a modified Valsalva maneuver using a gauge pressure gauge applied to the TCD bubble test) is often used in clinical TCD bubble testing.

[0003] The traditional "LP insufflation method" mostly uses a simple device made with an injection syringe. Since the syringe does not fit the patient's mouth and is not compatible with the catheter connection, the auxiliary effect is poor. It has the disadvantages of unprofessional form, loose oral wrapping, difficulty in maintaining the insufflation time for 10 seconds, and poor auxiliary effect. In addition, the patient needs to hold the simple device in hand all the time during the insufflation, which is inconvenient. Therefore, there is a lack of professional standard equipment to perform the "LP insufflation method" in clinical practice. The design of this utility model meets the hospital diagnosis and treatment standards and hospital infection quality control requirements. It has a simple and standardized appearance, the oral insufflation nozzle complies with the principles of mechanics, is tightly wrapped, and can better maintain the duration required for the examination, thereby improving the positive detection rate, reducing false negatives, and being more scientific, stable, and accurate.

Specific implementation

[0030] The technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model, obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by the ordinary skill in the art without creative labor are within the scope of the utility model protection.

[0031] Embodiment

[0032] Please refer to Figures 1-7In an embodiment of the present invention, an auxiliary device for performing the LP blowing method in a TCD foaming experiment includes a mouthpiece 100, a gauge pressure gauge 200, an air supply pipe 300 and an auxiliary fixing member 400. The mouthpiece 100 includes a shell 110 and a shell 2 120. The sides of the shell 110 and the shell 2 120 that are close to each other are respectively provided with a docking shell 111 and a docking shell 2 121. The docking shell 111 and the docking shell 2 121 are plugged into each other. The ends of the shell 110 and the shell 2 120 that are away from each other are respectively provided with an elliptical cylindrical interface 112 and a cylindrical interface 1 123. The lower end of the gauge pressure gauge 200 is provided with a cylindrical interface 210. The air supply pipe 300 is composed of three hollow cylinders, and the two ends are respectively connected to the cylindrical interface 210 and the cylindrical Interface 123 and the auxiliary fixing part 400 can fix the mouthpiece 100 in the patient's oral position. The inner diameter of the cylindrical interface 123 is 7 mm and the outer diameter is 9 mm, which are compatible with the air tube 300. The inner diameter of the elliptical cylindrical interface 112 is 21 mm × 7 mm and the outer diameter is 27 mm × 14 mm. The air tube 300 is 50 cm long. The inner diameter of the docking interface on one side of the air tube 300 is 9 mm and the outer diameter is 11 mm, which are compatible with the cylindrical interface 123. The inner diameter of the docking interface on the other side of the air tube 300 is 9 mm and the outer diameter is 11 mm, which are compatible with the cylindrical interface 210. The inner diameter of the cylindrical interface 210 is 7 mm and the outer diameter is 9 mm, which are compatible with the air tube 300.

[0033] Specifically, the mouthpiece 100 is made of PE, the gauge pressure gauge 200 is made of stainless steel and glass, the air supply tube 300 is made of PVC, and the auxiliary fixing part 400 is made of silicone. The auxiliary fixing part 400 is combined with the mouthpiece 100 and fixed on the patient's head. The cylindrical interface 123 is connected to the docking interface at one end of the air supply tube 300, and the elliptical cylindrical interface 112 is in contact with the patient's mouth. The patient's lips wrap around the elliptical cylindrical interface 112 to ensure that the blowing is effective. 300 is cylindrical and hollow inside, which can transmit the air blown out by the patient. The cylindrical interface 210 at the lower end of the gauge pressure gauge 200 is connected to the docking interface at the other end of the air supply tube 300. The air blown out by the patient is sent to the gauge pressure gauge 200 through the air supply tube 300. The gauge pressure gauge 200 displays the blowing pressure in real time. When the patient blows hard, the doctor pays attention to the value on the gauge pressure gauge 200, prompting the patient to maintain the blowing pressure at 40 mmHg to ensure the completion of the modified Valsalva maneuver.

[0034] like Figure 3 As shown, in this embodiment, a replaceable filter cotton 130 is placed between the interiors of the first docking shell 111 and the second docking shell 121 , and a notch 122 is opened on the outer wall of the second docking shell 121 .

[0035] In this embodiment, the docking shell 2 121 and the docking shell 1 111 can be separated from each other through the notch 122 on the docking shell 2 121, and the replaceable filter cotton 130 is placed between the two, and then the docking shell 2 121 and the docking shell 1 111 are merged together. The main function of the filter cotton 130 is to prevent secretions such as saliva from directly entering the air supply pipe 300, which facilitates subsequent cleaning and disinfection.

[0036] like Figure 2 As shown, in this embodiment, the auxiliary fixing member 400 includes a fixing sleeve 410, the inner wall of the fixing sleeve 410 is socketed with the outer wall of the shell 2 120, and the outer wall of the fixing sleeve 410 is symmetrically fixedly connected to two connecting strips 411, and the other ends of the two connecting strips 411 are fixedly connected to earrings 412.

[0037] During specific implementation, the fixing sleeve 410 is sleeved on the outer wall of the shell 2 120, and the other side of the fixing sleeve 410 is also hollowed out, which does not affect the connection between the cylindrical interface 1 123 and the air supply tube 300. After sleeve connection, the patient puts the elliptical cylindrical interface 112 into his mouth and puts the two earrings 412 on the two ears respectively, so that the auxiliary fixing part 400 assists in fixing the mouthpiece 100, avoiding the patient's continuous manual support of the mouthpiece 100.

[0038] It will be apparent 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 characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
