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

[0020] See also Figure 1-5 The present invention provides a technical solution: a device for collecting male urethral secretions, comprising an elastic pressure airbag 1, which is a closed elastic pressure airbag. When an external force is applied to the elastic pressure airbag 1 for squeezing, the elastic pressure airbag 1 undergoes elastic deformation. When the force applied to the elastic pressure airbag 1 is removed, the elastic pressure airbag 1 returns to its initial state. The elastic pressure airbag 1 is connected to a connecting tube 2 with a return bend. The end of the connecting tube 2 away from the elastic pressure airbag 1 is connected to a sampling gas column 3. Before use, the sampling gas column 3 is bent in the return bend. Under the action of the connecting tube 2, the sample is in the elastic pressure airbag 1. When it needs to be used, the connecting tube 2 with a return bend is inserted into the urethral opening of the male patient, and a force is applied to the elastic pressure airbag 1 to make the elastic pressure airbag 1 elastically deformed. The gas in the elastic pressure airbag 1 rushes to the return bend of the connecting tube 2. When the air pressure at the return bend of the connecting tube 2 increases, the connecting tube 2 with a return bend can be straightened, and the sampling gas column 3 is driven to evert out of the inner cavity of the elastic pressure airbag 1 and enter the urethra of the male patient to collect urethral secretions.

[0021] Specifically, a protective shell 4 is provided on the outside of the elastic pressure airbag 1, and a push button 5 capable of squeezing the elastic pressure airbag 1 is installed on the protective shell 4. By applying an external force to the push button 5, the push button 5 moves relative to the protective shell 4. When the push button 5 moves, the elastic pressure airbag 1 in the protective shell 4 is squeezed, so that the working deformation of the elastic pressure airbag 1 is stable.

[0022] Specifically, a return spring 6 for applying a return force to the push key 5 is installed between the push key 5 and the protective shell 4. When the force applied to the push key 5 is removed, the return spring 6 can restore the push key 5 to its initial position and wait for the next operation.

[0023] Specifically, the connecting tube 2 is detachably connected to the elastic pressure airbag 1; the elastic pressure airbag 1 is provided with a working tube 7 that penetrates the side wall of the protective shell 4, and the working tube 7 is detachably connected to the connecting tube 2. When the working tube 7 is connected to the connecting tube 2, a sealed connection is achieved to prevent air leakage. The protective shell 4 is provided with a locking structure for locking the connecting tube 2. The connecting tube 2 is detachably connected to the working tube 7, and each operation only requires replacing the connecting tube 2 and the sampling gas column 3, thereby saving the use cost. At the same time, the locking structure can make the connecting tube more stable when connected to the working tube 7.

[0024] Specifically, the locking structure includes an auxiliary ring 8, which is fixedly mounted on the outer wall of the connecting pipe 2. The protective shell 4 is slidably connected with a locking rod 9 for locking the auxiliary ring 8. The locking rod 9 slides on the protective shell 4. When the working pipe 7 is connected to the connecting pipe 2, the locking rod 9 is located on the side of the auxiliary ring 8 away from the protective shell 4. During operation, the working pipe 7 is separated from the connecting pipe 2.

[0025] Specifically, a magnetic layer 10 is provided on the outer wall of the protective shell 4 and on the outer side of the working tube 7, and the auxiliary ring 8 is a metal auxiliary ring that can be magnetically connected to the magnetic layer 10 to achieve quick connection.

[0026] Specifically, the sampling gas column 3 is provided with a moisture absorbing layer 11, which can better absorb the secretions in the urethra.

[0027] Working principle: Before use, the sampling gas column 3 is in the elastic pressure airbag 1 under the action of the connecting tube 2 with a return bend. When it is needed, the connecting tube 2 with a return bend is inserted into the urethral opening of the male patient, and an external force is applied to the pressing key 5 to make the pressing key 5 move relative to the protective shell 4. When the pressing key 5 moves, the elastic pressure airbag 1 in the protective shell 4 is squeezed to make the elastic pressure airbag 1 elastically deformed, and the gas in the elastic pressure airbag 1 rushes to the return bend of the connecting tube 2. When the air pressure at the return bend of the connecting tube 2 increases, the connecting tube 2 with a return bend can be straightened, and the sampling gas column 3 is driven to turn out of the inner cavity of the elastic pressure airbag 1 and enter the urethra of the male patient to collect urethral secretions. After the collection is completed, under the action of the reset spring 6 and the elastic pressure airbag 1 itself, the elastic pressure airbag 1 returns to its initial state. At this time, the sampling gas column 3 returns to a soft state, which is convenient for pulling out from the patient's urethra and will not cause discomfort to the patient.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
