Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly relates to a medical secretion sampler for digestive medicine nursing. Background Art

[0002] The digestive medicine department is a clinical tertiary discipline that mainly studies diseases of the esophagus, stomach, small intestine, large intestine, liver, gallbladder, and pancreas. There are a wide variety of digestive medicine diseases, with a broad medical knowledge and complex and delicate operations; during the rehabilitation nursing of the esophagus, intestine, or gastric cardia after surgery, there are often secretions discharged. In order to judge the postoperative healing effect, it is necessary to sample the secretions and test and analyze their components.

[0003] The existing secretion sampling devices have a single usage method. Either they can only dip the secretions or they can only extract the secretions, that is: if only a small amount of secretions are needed, a sampling device that cooperates with consumables such as cotton swabs must be used; if a large amount of secretions are needed, a sampling device that cooperates with a medical aspirator must be used. Therefore, the scope of application is small, and the two sampling devices cannot be switched arbitrarily. Once the wrong choice is made, the whole device must be replaced and the operation repeated. Therefore, it is more inconvenient to use; in addition, the existing secretion sampling devices lack the functions of expansion and anti-slip. The secretions are easily dispersed due to the peristalsis of the sampling site, and at the same time, the secretion sampling device is also easily separated from the sampling site, resulting in the inability of the secretion sampling device to quickly and accurately obtain the secretions, and it is necessary to adjust the orientation multiple times to complete. Therefore, the sampling efficiency is low, time-consuming and laborious, and it is urgently needed to be solved. Summary of the Invention

[0004] Aiming at the current situation of the above-mentioned existing technology, the technical problem to be solved by the present invention is to provide a medical secretion sampler for digestive medicine nursing that has two usage methods to expand the scope of application, and the switching steps between the two usage methods are simple and convenient, so it greatly facilitates the use and also greatly improves the sampling efficiency.

[0027] To keep the following description of the embodiments of the present invention clear and concise, detailed descriptions of known functions and known components are omitted in the present invention.

[0028] As Figures 1 to 5 shown, a medical secretion sampler for digestive medicine nursing includes a cylinder body 1, a cover plate 2 horizontally fixed at the top opening of the cylinder body 1, a shelf plate 3 horizontally fixed inside the cylinder body 1, and a diversion unit disposed between the cover plate 2 and the shelf plate 3;

[0029] The diversion unit includes an outer tube 4 vertically inserted and screwed into the shelf plate 3 and concentrically disposed inside the cylinder body 1, a baffle 6 horizontally fixed at the upper end opening of the outer tube 4, a guide tube 7 vertically inserted through the cover plate 2 and concentrically distributed with the outer tube 4, a locking spring 8 sleeved outside the guide tube 7 and between the cover plate 2 and the baffle 6, and an inner tube 5 vertically and concentrically inserted and screwed into the guide tube 7;

[0030] The lower end opening of the guide tube 7 is fixed to the top of the baffle 6, and the locking spring 8 is always in a compressed state so that its upper and lower ends respectively abut against the bottom of the cover plate 2 and the top of the baffle 6;

[0031] The lower end of the inner tube 5 passes through the baffle 6 and is movably inserted and connected into the outer tube 4, and the outer peripheral surface of the inner tube 5 is sealed and slidably fitted to the inner peripheral surface of the outer tube 4;

[0032] An axial through hole 51 is opened at the center of the closed lower end of the inner tube 5, and a plurality of lateral through holes 52 are opened on the outer peripheral surface of the lower end of the inner tube 5;

[0033] An outlet joint 10 is also sleeved and fixed outside the upper end opening of the inner tube 5.

[0034] An expansion mechanism 9 is also provided at the lower end opening of the cylinder body 1. The expansion mechanism 9 includes a traction shaft 92 that is horizontally and rotatably eccentrically inserted on one side of the cylinder body 1 and above the shelf plate 3, two conical tiles 91 provided below the cylinder body 1 and distributed diagonally to each other, and two traction frames 93 that are movably inserted through the shelf plate 3 and are respectively located above the two conical tiles 91.

[0035] The inner end of the traction shaft 92 is rotatably connected to the inner wall of the cylinder body 1. Two external thread portions 921 are formed on the outer peripheral surface of the traction shaft 92 and are arranged in sequence along the axial direction. The spiral directions of the two external thread portions 921 are opposite to each other.

[0036] The lower sides of the two traction frames 93 are respectively fixed to the inner walls of the two conical tiles 91. A nut 95 is also fixed to the upper side of each of the two traction frames 93. The two nuts 95 are respectively sleeved and screwed outside the two external thread portions 921.

[0037] The lower side edges of the two conical tiles 91 are each formed with a vertically arranged arc-shaped expansion plate 911 downward. The two arc-shaped expansion plates 911 are arranged diagonally to each other.

[0038] An anti-slip assembly 11 is also provided on the outer walls of the two arc-shaped expansion plates 911. The anti-slip assembly 11 includes a plurality of strip-shaped air bags 111 vertically fixed on the outer wall of the arc-shaped expansion plate 911 and distributed in sequence along the circumferential direction, and an air pipe 112 inserted into the arc-shaped expansion plate 911 and communicating with the inside of any one strip-shaped air bag 111 and located between the two conical tiles 91. The interiors of any two adjacent strip-shaped air bags 111 are in communication with each other.

[0039] A plurality of vertically distributed and sequentially arranged strip-shaped grooves 912 are formed on the outer wall of the arc-shaped expansion plate 911. The number of strip-shaped grooves 912 is equal to the number of strip-shaped air bags 111. Each strip-shaped air bag 111 is arranged in a corresponding strip-shaped groove 912. The edge of the inner side opening of the strip-shaped air bag 111 is sealed and fixed to the bottom surface of the strip-shaped groove 912.

[0040] At least one through hole 913 is formed between the adjacent inner walls of any two adjacent strip-shaped grooves 912. The interiors of any two adjacent strip-shaped air bags 111 are in communication with each other through each through hole 913 located between the two strip-shaped air bags 111. A ventilation hole 914 is formed between the inner wall of the conical tile 91 and the bottom surface of any one strip-shaped groove 912. One end of the air pipe 112 is hermetically inserted into the inner part of the opening at one end of the ventilation hole 914 located on the inner wall of the conical tile 91.

[0041] A slot hole 31 located on one side of the outer tube 4 is formed in the shelf plate 3, and both traction frames 93 in the expansion mechanism 9 are movably inserted into the slot hole 31.

[0042] A first runner sleeve 12 is also sleeved and fixed outside the guide tube 7, and a second runner sleeve 13 located above the first runner sleeve 12 is also sleeved and fixed outside the inner tube 5.

[0043] A knob 94 arranged concentrically is also fixed to the outer end of the traction shaft 92.

[0044] Usage method:

[0045] First, drain the air in each strip-shaped airbag 111 and press each strip-shaped airbag 111 into a corresponding strip-shaped groove 912 by hand, then hold the cylinder body 1 and insert the arc-shaped expansion plates 911 on the two conical tiles 91 in the expansion mechanism 9 into the opening of the intestine or esophagus or the cardiac part of the stomach.

[0046] Subsequently, rotate the knob 94 by hand to drive the rotation of the traction shaft 92, and then drive the two traction frames 93 to move away from each other with the same speed and amplitude by using the screw connection principle between the two external thread parts 921 and the two nuts 95, and then gradually increase the distance between the two arc-shaped expansion plates 911 until the outer walls of the two arc-shaped expansion plates 911 are both attached to the inner mucosa of the intestine or esophagus or the cardiac part of the stomach.

[0047] Next, introduce air into the other end of the trachea 112 with appropriate pressure and maintain the pressure. The air in the trachea 112 will enter a corresponding strip-shaped groove 912 through the ventilation holes 914, and then fill the strip-shaped airbag 111 located in the above strip-shaped groove 912. Subsequently, fill each strip-shaped airbag 111 through each through hole 913. The outer sides of the filled strip-shaped airbags 111 all extend out of the opening of the strip-shaped groove 912 and press tightly on the inner mucosa of the intestine or esophagus or the cardiac part of the stomach, thereby playing an anti-slip role to prevent the two arc-shaped expansion plates 911 from easily detaching from the intestine or esophagus or the cardiac part of the stomach.

[0048] Then, rotate the first runner sleeve 12 by hand to drive the outer tube 4 together with the guide tube 7, the baffle 6 and the first runner sleeve 12 to move towards the direction of the two arc-shaped expansion plates 911 by means of the guide tube 7 and the baffle 6. Since the inner tube 5 is concentrically inserted and screwed into the guide tube 7, there is a certain binding force between the inner tube 5 and the guide tube 7. Therefore, when the guide tube 7 moves, it will drive the inner tube 5 and the second runner sleeve 13 to move synchronously, and then the closed end at the lower end of the inner tube 5 gradually extends into the intestine and finally inserts into the secretion; during this process, the rebound force of the locking spring 8 is gradually released, but its two ends always press tightly on the bottom of the cover plate 2 and the top of the baffle 6. When the hand releases the first runner sleeve 12, it is difficult for the position of the outer tube 4 to move spontaneously.

[0049] After that, if only a small amount of secretion needs to be obtained and a cotton swab is needed to dip it, one hand can be used to hold the first rotating wheel sleeve 12 to prevent the guide tube 7 and the outer tube 4 from rotating, and the other hand can be used to screw the second rotating wheel sleeve 13 to drive the inner tube 5 to continue to penetrate, so that the multiple lateral through holes 52 on the inner tube 5 gradually move to the outside of the lower end opening of the outer tube 4, so that the secretion enters the inside of the inner tube 5 through the axial through hole 51 and the multiple lateral through holes 52; then, the end of the cotton swab tied with the sanitary cotton is inserted into the inside of the inner tube 5 until the sanitary cotton is immersed in the secretion located inside the inner tube 5, wait for a few seconds and then pull out the cotton swab outward, so that the dipping of the secretion is completed.

[0050] If a large amount of secretion needs to be obtained, on the premise of ensuring that the guide tube 7 and the outer tube 4 are fixed, the second rotating wheel sleeve 13 needs to be rotated in the reverse direction in the same way to drive the inner tube 5 to retract into the outer tube 4 until each lateral through hole 52 is located inside the lower end opening of the outer tube 4, and only the axial through hole 51 is immersed in the secretion. Then, the first rotating wheel sleeve 12 can be screwed as needed to drive the outer tube 4 and the inner tube 5 to rotate together, and then the depth of the lower end closed part of the inner tube 5 extending into the secretion can be adjusted in the same way; subsequently, the end opening of the liquid inlet tube of the medical aspirator is hermetically sleeved outside the liquid outlet joint 10. After starting the medical aspirator, the secretion will enter the inner tube 5 through the axial through hole 51, and then enter the liquid inlet tube of the medical aspirator through the upper end opening of the inner tube 5, so that the extraction of the secretion is completed; since the outer peripheral surface of the inner tube 5 is sealed and slidably attached to the inner peripheral surface of the outer tube 4, once the lateral through hole 52 retracts into the outer tube 4, the secretion can only enter the inner tube 5 through the axial through hole 51.

[0051] After sampling, first drain the air in each strip-shaped airbag 111 through the air tube 112, and then use the hand to reverse-screw the knob 94 to drive the traction shaft 92 to rotate in the reverse direction, and then drive the two arc-shaped expansion plates 911 to gradually approach in the same way. Finally, pull the two arc-shaped expansion plates 911 out of the intestine or esophagus or the cardiac orifice of the stomach.

[0052] The present invention can switch the sampling method according to needs. It can not only cooperate with consumables such as cotton swabs to dip a small amount of secretion, but also cooperate with a medical aspirator to extract a large amount of secretion. Furthermore, it has two usage methods to expand the scope of application, and the switching steps between the two usage methods are simple and convenient, so it greatly facilitates the use; in addition, the expansion mechanism 9 and the anti-slip component 11 are respectively provided with expansion and anti-slip functions, so as to ensure that the secretion can be concentrated in one place so that the inner tube 5 can quickly and accurately obtain the secretion, and at the same time it can effectively prevent the two arc-shaped expansion plates 911 from detaching from the sampling site. The sampling can be successfully completed only once, thus greatly improving the sampling efficiency.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. These modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
