Description

Technical Field

[0001] This invention relates to the field of medical equipment, and in particular to a hospital pneumatic tube system. Background Technology

[0002] In hospitals, a large number of items are transported between different departments and buildings every day, including prescriptions, test reports, medicines, laboratory samples, and medical equipment. These items are mostly small and lightweight, but numerous. Manual transport is not only wasteful of manpower and inefficient, but also increases hospital traffic, putting even more strain on already overloaded elevators and increasing the risk of lost items during transport, leading to serious consequences. A pneumatic logistics system, replacing manual transport, can solve these problems.

[0003] The transfer bottle is the sole carrier in a pneumatic logistics system. Because it moves at high speed within the pipe, navigating vertical and horizontal bends without slowing down, it collides with the pipe's inner wall and its contents are subjected to various vibrations. This places higher demands on the design of the transfer bottle. Currently, while different designs of transfer bottles can achieve the transfer of goods, accidents such as damage to the contents due to collisions, items scattering into the pipe due to vibrations, and pipe blockages frequently occur during transport. Summary of the Invention

[0004] The main objective of this invention is to provide a hospital pneumatic logistics system that facilitates loading and unloading of items and prevents bottle caps from falling off due to collisions from all directions during high-speed transportation, thus ensuring the safety and stability of items during transport.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: a hospital pneumatic logistics system, comprising several stations, a transmission pipeline connecting the stations, and a pneumatic drive device. The pneumatic drive device is used to drive a transmission bottle to be transmitted between stations through the transmission pipeline. The transmission bottle includes a bottle body for containing items, a bottle mouth configured as a tube, and a bottle cap. One end of the bottle mouth is connected to the end of the bottle body, and the bottle cap is installed on the other end of the bottle mouth. The bottle cap has a first flange extending radially outward on one circumference, and a first groove area for the first flange to be inserted into the corresponding circumference of the bottle mouth. The bottle cap has a second groove area on the other circumference, and a second flange extending radially outward on the corresponding circumference of the bottle mouth for being inserted into the second groove area. The first flange and the second groove area are spaced apart in the circumferential direction of the bottle cap, and the first flange and the second flange are spaced apart in the axial direction of the bottle cap and the bottle mouth. A first mounting hole is axially formed on the end face of the bottle mouth near the bottle cap. A second mounting hole corresponding to the first mounting hole is formed on the end face of the bottle cap near the bottle mouth. A rotating sleeve fixed relative to the bottle cap is installed in the second mounting hole. A retaining sleeve fixed relative to the bottle mouth is installed in the first mounting hole. A pin passes through the retaining sleeve and the rotating sleeve in sequence, and the upper end of the pin is rotatably installed in the rotating sleeve, so that the rotating sleeve can rotate around the upper end of the pin. The first mounting hole and the second mounting hole both include a circular hole and a square hole that are interconnected. The rotating sleeve and the retaining sleeve both include a circular sleeve and a square sleeve corresponding to the circular hole and the square hole, respectively. The lower end of the pin extending from below the retaining sleeve has a radially outward flange. A compressed spring is fitted onto the pin, and the upper and lower ends of the spring are in contact with the lower end face of the retaining sleeve and the upper end face of the pin flange, respectively. The upper end of the pin is connected to the rotating sleeve through a retaining ring and a retaining groove, which restricts the pin from moving downward in the axial direction. The retaining sleeve and the rotating sleeve are connected by two protrusions and two slots into which the protrusions can be inserted. The two side faces of the protrusions are symmetrically arranged slopes, which slope inward in the direction close to the slot. The inner surface of the slot is a slope that matches the slope of the protrusion. When the bottle cap is in the closed state, all the protrusions are inserted into one slot. When the bottle cap is in the open state, all the protrusions are inserted into the other slot. The bottle body is provided with a protective sleeve, and a side plate is installed at both ends of the protective sleeve. The two side plates are connected by a support shaft, and a shelf is installed on the support shaft. Both ends of the support shaft are connected to the side plate through a jumping ring. The jumping ring is embedded in the mounting groove on the side plate and can move in the radial direction. The side plate is provided with a number of spring grooves with built-in springs at intervals along the circumference. The spring grooves are opened in the radial direction and communicate with the mounting groove. One end of a spring pin is embedded in the spring groove and connected to the spring. The other end of the spring pin is in contact with the circumferential surface of the jumping ring. The bottle body is provided with a shelf, which includes at least two parallel and spaced support plates and at least two fixing rods connecting adjacent support plates. Each of the support plates has at least one groove on its opposite surface, thereby forming an area for inserting a storage body between two opposite grooves. The support plates and the storage body are respectively provided with magnets that attract each other.

[0006] The following are further improvements to the above technical solution: 1. In the above scheme, the square sleeve portion of the rotating sleeve and the retaining sleeve are respectively embedded in the square hole portion of the second mounting hole and the first mounting hole, so that the rotating sleeve and the retaining sleeve are relatively fixed to the bottle cap and the bottle mouth.

[0007] 2. In the above scheme, two grooves are formed on one side surface of the support plate.

[0008] 3. In the above solution, the storage body is a test tube rack or a storage box.

[0009] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art: 1. The hospital pneumatic logistics system of the present invention, through the cooperation of two sets of flanges and grooves on the bottle cap and bottle mouth, and the staggered arrangement of the two sets of flanges and grooves in the circumferential direction, not only achieves a sealed connection between the bottle cap and the bottle mouth, but also prevents the bottle cap from falling off due to collisions from all directions during high-speed transportation, thus ensuring the safety and stability of the items during transportation; in addition, through the modular design of the storage rack, it is not only convenient to load and unload items, but also ensures the safety and stability of the items inside the bottle during transportation.

[0010] 2. The hospital pneumatic logistics system of the present invention, through the cooperation of two mounting holes and a pin, not only realizes the connection between the bottle cap and the bottle mouth for convenient use, but also allows the bottle cap to rotate around the pin for easy opening and closing. Furthermore, through the spring cooperation with the mounting structure of the pin and the bottle cap, an axial force is elastically applied to the bottle cap, which facilitates opening while ensuring that the bottle cap and the bottle mouth remain tightly connected in the closed state, maintaining the airtightness of the bottle during transportation, thereby ensuring the safety and stability of the transport of goods. In addition, it can avoid the risk of accidental opening or closing of the bottle cap due to friction and smoothing of the inner surface of the bottle cap caused by repeated opening and closing after long-term use, which could lead to the bottle cap being accidentally opened or closed during high-speed movement or when picking up and placing items.

[0011] 3. The hospital pneumatic tube system of the present invention includes a protective sleeve inside the bottle body. Each end of the protective sleeve has a side plate installed on it, and the two side plates are connected by a support shaft. A shelf is mounted on the support shaft. Each end of the support shaft is connected to the side plate via a jumping ring. The jumping ring is embedded in a mounting groove on the side plate and can move radially. The side plate has several spring grooves with built-in springs spaced circumferentially. These spring grooves are radially opened and communicate with the mounting grooves. One end of a spring pin is embedded in the spring groove and... The spring connection, with the other end of the spring pin contacting the circumferential surface of the jumping ring, disperses the radial force on the items inside the bottle. This force is then offset by the repeated elastic movement of the spring, causing the entire shelf to "float," protecting the items inside during multiple transports. Furthermore, the sheath and side panels are elastically installed as a single unit inside the bottle. Even in the extreme case where the bottle cap completely falls off and is damaged, the integrated structure formed by the sheath and side panels can still protect the internal items, minimizing damage to high-value items.

[0014] The present patent can be further understood through the specific embodiments given below, but they are not intended to limit the present patent.

[0015] Example 1: A hospital pneumatic logistics system includes several stations 31, a transmission pipeline 32 connecting the stations 31, and a pneumatic drive device 33, wherein the pneumatic drive device 33 is used to drive the transmission bottle to be transmitted between the stations 31 through the transmission pipeline 32. The transport bottle includes a bottle body 1 for containing items, a bottle mouth 2 configured as a tube, and a bottle cap 3. One end of the bottle mouth 2 is connected to the end of the bottle body 1, and the bottle cap 3 is installed on the other end of the bottle mouth 2. The bottle cap 3 has a first flange portion 301 extending radially outward on one circumference, and the bottle mouth 2 has a first groove area 201 for the first flange portion 301 to be inserted on the corresponding circumference. The bottle cap 3 has a second groove area 302 on the other circumference, and the bottle mouth 2 has a second flange portion 202 extending radially outward on the corresponding circumference for being inserted into the second groove area 302. The first flange portion 301 and the second groove area 302 are spaced apart in the circumferential direction of the bottle cap 3, and the first flange portion 301 and the second flange portion 202 are spaced apart in the axial direction of the bottle cap 3 and the bottle mouth 2. A first mounting hole 9 is axially formed on the end face of the bottle mouth 2 near the bottle cap 3. A second mounting hole 10 corresponding to the first mounting hole 9 is formed on the end face of the bottle cap 3 near the bottle mouth 2. A rotating sleeve 11 fixed relative to the bottle cap 3 is installed in the second mounting hole 10. A retaining sleeve 12 fixed relative to the bottle mouth 2 is installed in the first mounting hole 9. A pin 13 passes through the retaining sleeve 12 and the rotating sleeve 11 in sequence, and the upper end of the pin 13 is rotatably installed in the rotating sleeve 11, so that the rotating sleeve 11 can rotate around the upper end of the pin 13. The lower end of the pin 13 extending from below the retaining sleeve 12 has a radially outward flange 14. A compressed spring 15 is fitted onto the pin 13, and the upper and lower ends of the spring 15 are in contact with the lower end face of the retaining sleeve 12 and the upper end face of the flange 14 of the pin 13, respectively. The upper end of the pin 13 is connected to the rotating sleeve 11 through a retaining ring and a retaining groove, which restricts the pin 13 from moving downward in the axial direction. The retaining sleeve 12 and the rotating sleeve 11 are connected by at least one protrusion 16 and at least two slots 17 into which the protrusion 16 can be inserted. The two side end faces of the protrusion 16 are symmetrically arranged slopes, which are inclined inward in the direction close to the slot 17. The inner surface of the slot 17 is a slope that matches the slope of the protrusion 16. When the bottle cap 3 is in the closed state, the protrusion 16 is fully inserted into one slot 17. When the bottle cap 3 is in the open state, the protrusion 16 is fully inserted into the other slot 17. A protective sleeve 18 is provided inside the bottle body 1. A side plate 19 is installed at both ends of the protective sleeve 18. The two side plates 19 are connected by a support shaft 20. A shelf 21 is installed on the support shaft 20. Both ends of the support shaft 20 are connected to the side plate 19 through a jumping ring 23. The jumping ring 23 is embedded in the mounting groove 24 on the side plate 19 and can move in the radial direction. The side plate 19 is provided with a number of spring grooves 25 with built-in springs at intervals along the circumference. The spring grooves 25 are opened radially and communicate with the mounting grooves 24. One end of a spring pin 30 is embedded in the spring groove 25 and connected to the spring. The other end of the spring pin 30 is in contact with the circumferential surface of the jumping ring 23. The bottle body 1 is provided with a shelf 21. The shelf 21 includes at least two parallel and spaced support plates 26 and at least two fixing rods 27 connecting adjacent support plates 26. Each of the support plates 26 has at least one groove 28 on its opposite surface, thereby forming an area for inserting a storage body 29 between the two grooves 28 facing each other. The support plates 26 and the storage body 29 are respectively provided with magnets that attract each other.

[0016] The first mounting hole 9 and the second mounting hole 10 mentioned above both include a circular hole and a square hole that are interconnected. The rotating sleeve 11 and the retaining sleeve 12 both include a circular sleeve and a square sleeve corresponding to the circular hole and the square hole, respectively. The square sleeve of the rotating sleeve 11 and the retaining sleeve 12 are respectively embedded in the square hole of the second mounting hole 10 and the first mounting hole 9, so that the rotating sleeve 11 and the retaining sleeve 12 are relatively fixed to the bottle cap 3 and the bottle mouth 2. Without the use of any connecting parts, the retaining sleeve and the rotating sleeve can remain stationary inside the bottle mouth and the bottle cap under any circumstances.

[0017] The number of spring grooves 25 mentioned above is 6.

[0018] The aforementioned pneumatic drive device 33 includes an air compressor and a reversing assembly.

[0019] There are two support plates 26.

[0020] The aforementioned storage container is a test tube rack.

[0021] Example 2: A hospital pneumatic logistics system includes several stations 31, a transmission pipeline 32 connecting the stations 31, and a pneumatic drive device 33, wherein the pneumatic drive device 33 is used to drive the transmission bottle to be transmitted between the stations 31 through the transmission pipeline 32. The transport bottle includes a bottle body 1 for containing items, a bottle mouth 2 configured as a tube, and a bottle cap 3. One end of the bottle mouth 2 is connected to the end of the bottle body 1, and the bottle cap 3 is installed on the other end of the bottle mouth 2. The bottle cap 3 has a first flange portion 301 extending radially outward on one circumference, and the bottle mouth 2 has a first groove area 201 for the first flange portion 301 to be inserted on the corresponding circumference. The bottle cap 3 has a second groove area 302 on the other circumference, and the bottle mouth 2 has a second flange portion 202 extending radially outward on the corresponding circumference for being inserted into the second groove area 302. The first flange portion 301 and the second groove area 302 are spaced apart in the circumferential direction of the bottle cap 3, and the first flange portion 301 and the second flange portion 202 are spaced apart in the axial direction of the bottle cap 3 and the bottle mouth 2. A first mounting hole 9 is axially formed on the end face of the bottle mouth 2 near the bottle cap 3. A second mounting hole 10 corresponding to the first mounting hole 9 is formed on the end face of the bottle cap 3 near the bottle mouth 2. A rotating sleeve 11 fixed relative to the bottle cap 3 is installed in the second mounting hole 10. A retaining sleeve 12 fixed relative to the bottle mouth 2 is installed in the first mounting hole 9. A pin 13 passes through the retaining sleeve 12 and the rotating sleeve 11 in sequence, and the upper end of the pin 13 is rotatably installed in the rotating sleeve 11, so that the rotating sleeve 11 can rotate around the upper end of the pin 13. The lower end of the pin 13 extending from below the retaining sleeve 12 has a radially outward flange 14. A compressed spring 15 is fitted onto the pin 13, and the upper and lower ends of the spring 15 are in contact with the lower end face of the retaining sleeve 12 and the upper end face of the flange 14 of the pin 13, respectively. The upper end of the pin 13 is connected to the rotating sleeve 11 through a retaining ring and a retaining groove, which restricts the pin 13 from moving downward in the axial direction. The retaining sleeve 12 and the rotating sleeve 11 are connected by at least one protrusion 16 and at least two slots 17 into which the protrusion 16 can be inserted. The two side end faces of the protrusion 16 are symmetrically arranged slopes, which are inclined inward in the direction close to the slot 17. The inner surface of the slot 17 is a slope that matches the slope of the protrusion 16. When the bottle cap 3 is in the closed state, the protrusion 16 is fully inserted into one slot 17. When the bottle cap 3 is in the open state, the protrusion 16 is fully inserted into the other slot 17. In use, the spring is inserted into the pin, and the entire spring is passed through the retaining sleeve inside the bottle mouth and the rotating sleeve of the bottle cap. After the spring is compressed to a certain length, the retaining ring is fixed into the groove at the front end of the pin, so that the retaining sleeve and the rotating sleeve are connected, thus connecting the bottle mouth and the bottle cap. The bottle mouth and the bottle cap are connected by the pin. The bottle cap rotates around the pin to open and close the bottle cap. The spring applies pressure to the rotating sleeve to achieve the pressure of the bottle cap on the bottle mouth, increasing the friction and making the bottle cap less likely to rotate. When the bottle cap is opened, the cap causes the rotating sleeve to rotate, keeping it stationary inside the bottle opening. Due to the cooperation of the protrusion and the groove, the rotating sleeve rotates and moves upwards simultaneously. The bottle cap also moves upwards accordingly and disengages from the bottle opening. When the groove completely disengages from the protrusion, the rotating sleeve rotates horizontally. After rotating 180°, the groove engages with the protrusion on the other side of the retaining sleeve, causing the rotating sleeve to fall back, and the bottle cap is opened 180°. When the bottle cap is opened, the rotating sleeve moves upward and increases the compression of the spring. Within a certain rotation angle, force is required to turn the bottle cap open. After rotating beyond that angle, the bottle cap rotates horizontally without the need for additional force. Moreover, the bottle cap can be positioned again after reaching 180°, and the cap will not wobble and thus affect the loading and unloading of items. In addition, when the bottle cap is subjected to a small impact, and under extreme conditions the bottle cap is opened at a small angle, due to the presence of the groove and the protrusion, when the protrusion is still inside the groove, the spring preload will pull the rotating sleeve back to its original position. At this time, the bottle cap that was opened by the impact will automatically close due to the spring tension, reducing the risk of the bottle cap being opened accidentally. A protective sleeve 18 is provided inside the bottle body 1. A side plate 19 is installed at both ends of the protective sleeve 18. The two side plates 19 are connected by a support shaft 20. A shelf 21 is installed on the support shaft 20. Both ends of the support shaft 20 are connected to the side plate 19 through a jumping ring 23. The jumping ring 23 is embedded in the mounting groove 24 on the side plate 19 and can move in the radial direction. The side plate 19 is provided with a number of spring grooves 25 with built-in springs at intervals along the circumference. The spring grooves 25 are opened radially and communicate with the mounting grooves 24. One end of a spring pin 30 is embedded in the spring groove 25 and connected to the spring. The other end of the spring pin 30 is in contact with the circumferential surface of the jumping ring 23. When the transfer bottle moves at high speed inside the pipe, it will vibrate due to friction with the inside of the pipe. It will also swing and impact when passing through vertical or horizontal bends, resulting in radial jump. When items are placed directly inside the transfer bottle, the risk is quite high, especially for high-value or fragile items. The radial force on the shelf is distributed to the support shaft, which in turn presses the force onto the jumping ring. The jumping ring is supported by spring pins and springs in various directions. The repeated elastic movement of the springs can counteract the radial jump, and the shelf as a whole is in a "floating" state, protecting the safety of the items inside the shelf during multiple transportation processes. The bottle body 1 is provided with a shelf 21. The shelf 21 includes at least two parallel and spaced support plates 26 and at least two fixing rods 27 connecting adjacent support plates 26. Each of the support plates 26 has at least one groove 28 on its opposite surface, thereby forming an area for inserting a storage body 29 between the two grooves 28 facing each other. The support plates 26 and the storage body 29 are respectively provided with magnets that attract each other.

[0022] The number of protrusions 16 and slots 17 mentioned above are both two, and they are evenly spaced along the circumference.

[0023] The number of spring grooves 25 mentioned above is 5.

[0024] The number of the aforementioned support plates 26 is 3.

[0025] Two grooves 28 are formed on one side surface of the aforementioned support plate 26.

[0026] When the above-mentioned hospital pneumatic logistics system is used, the cooperation of two sets of flanges and grooves on the bottle cap and bottle mouth, as well as the staggered arrangement of the two sets of flanges and grooves in the circumferential direction, not only achieves a sealed connection between the bottle cap and the bottle mouth, but also prevents the bottle cap from falling off due to collisions from all directions during high-speed transportation, thus ensuring the safety and stability of the goods during transportation. In addition, its modularly designed storage rack makes it easy to load and unload items, while also ensuring the safety and stability of the items inside the bottle during transportation. In addition, the connection between the bottle cap and the bottle mouth is achieved through the cooperation of two mounting holes and the pin, which is convenient to use. The bottle cap can also rotate around the pin, which is convenient for opening and closing the bottle cap. Furthermore, the spring, in conjunction with the mounting structure of the pin and the bottle cap, applies an axial force to the bottle cap elastically. This makes it easy to open the cap while ensuring that the bottle cap and the bottle mouth remain tightly connected when closed, maintaining the airtightness of the bottle during transportation and thus ensuring the safety and stability of the goods during transportation. Furthermore, this can prevent the risk of the cap accidentally opening or closing due to friction on the inner surface of the cap becoming smooth after long-term use, which could occur when the bottle is moving at high speed or when picking up or putting down items. In addition, the radial force on the items inside the bottle can be dispersed and then offset by the repeated elastic movement of the spring, so that the entire shelf is in a "floating" state, protecting the safety of the items inside the shelf during multiple transportation processes. Furthermore, the sleeve and side panels are elastically installed as a whole inside the bottle. Even in the extreme case where the bottle cap completely falls off and is damaged, the integrated structure formed by the sleeve and side panels can still protect the contents inside the bottle, minimizing damage to high-value items.

[0027] The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly. They should not be construed as limiting the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
