Description

Technical Field

[0001] This application relates to the technical field of medical devices, and particularly to a sputum suction control device. Background Art

[0002] A sputum suction machine is a device that uses an air negative pressure pump to create a negative pressure in the trachea and sucks sputum from the patient's mouth using the negative pressure.

[0003] The structure of the existing sputum suction device is as follows: a buffer bottle and a liquid storage bottle are connected by a pipeline. An interface for connecting a disposable connecting tube is provided at the bottle mouth of the liquid storage bottle. The buffer bottle is connected to the negative pressure pump, and a filter is provided on the negative pressure air pipe connecting the negative pressure pump and the buffer bottle. The purpose of the buffer bottle is to isolate the liquid storage bottle and the negative pressure pump (the negative pressure pump will be damaged if sputum enters). When the liquid storage bottle is full and the sputum is not cleaned in time, it can be temporarily stored in the buffer bottle to ensure that the sputum does not enter the negative pressure pump. The existing sputum suction device has the following problems: two bottles need to be used, occupying a large space; two bottles need to be cleaned each time, increasing the workload of medical staff; it cannot timely remind the medical staff to clean in time. If the buffer bottle is full of sputum and then used, there is a risk that the sputum will enter the negative pressure pump along the negative pressure air pipe.

Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present application.

[0030] Figure 1 Structural diagram of an existing sputum suction device, as Figure 1 shown, the liquid storage bottle 1 is connected to the buffer bottle 2 through a pipeline, the buffer bottle 2 is connected to a negative pressure pump through a filter, the bottle mouth of the liquid storage bottle 1 is connected to a disposable connecting pipe, the control system controls the negative pressure pump to pump air, and the doctor can suck out the sputum by inserting the disposable connecting pipe into the patient's mouth. The sputum enters the liquid storage bottle 1 through the disposable connecting pipe and then enters the buffer bottle 2. The function of the buffer bottle 2 is to isolate the liquid storage bottle 1 on the right and the negative pressure pump (the negative pressure pump will be damaged if sputum enters). When the liquid storage bottle 1 is full and the sputum is not cleaned in time, it can be temporarily stored in the buffer bottle 2 to ensure that the sputum does not enter the negative pressure pump.

[0031] Based on this, the existing sputum suction devices have the following problems: They require two bottles, namely a liquid storage bottle and a buffer bottle, which occupy a relatively large space; each cleaning requires cleaning two bottles, increasing the workload of medical staff; medical staff need to constantly monitor whether the liquid storage bottle is full, further increasing their workload and distracting their attention. If medical staff fail to clean the sputum in time and the buffer bottle is filled with sputum, and then it is used again, the sputum will enter the negative pressure pump along the negative pressure tube, damaging the negative pressure pump.

[0032] In response to this, the core of this application is to provide a sputum suction control device, which is used to reduce the occupied space of the device, the workload of medical staff, and the risk of damage to the negative pressure pump.

[0033] In order to enable those skilled in the art to better understand the solution of this application, the following further detailed description of this application will be given in conjunction with the accompanying drawings and specific embodiments.

[0034] Figure 2 The structural diagram of a sputum suction control device provided by an embodiment of this application is as Figure 2 shown. A sputum suction control device includes: a storage bottle, a fixing device, a liquid level detection device, and a central processing unit; the storage bottle includes a bottle body 3, a first connecting pipe 4 and a second connecting pipe 5 respectively connected to the bottle body 3. The first connecting pipe 4 is used to connect to a negative pressure pump, and the second connecting pipe 5 is used to connect to a sputum suction tube; the fixing device includes a first fixing bracket 6, a second fixing bracket 7, a telescopic part, a first abutting part 8 connected to the first fixing bracket 6, and a second abutting part 9 connected to the second fixing bracket 7. The first fixing bracket 6 is connected to the first abutting part 8 through the telescopic part, and / or the second fixing bracket 7 is connected to the second abutting part 9 through the telescopic part. The telescopic part is used to adjust the distance between the first abutting part 8 and the second abutting part 9; the liquid level detection device is arranged on the fixing device and is used to detect the sputum liquid level in the bottle body 3; the central processing unit is respectively communicatively connected to the negative pressure pump and the liquid level detection device.

[0035] In the embodiment of this application, the shape and size of the storage bottle are not specifically limited, and the first connecting pipe 4 and the second connecting pipe 5 are respectively sealed and inserted into the interior of the bottle body 3. In the embodiment of this application, the telescopic part is not specifically limited and can be a telescopic rod, etc. The first abutting part 8 and the second abutting part 9 respectively abut against the bottle body of the bottle body 3 to fix the bottle body 3. The telescopic part is used to adjust the distance between the first abutting part 8 and the second abutting part 9, and can be used to fix bottle bodies 3 of different sizes. In the embodiment of this application, the liquid level detection device is not specifically limited. When the sputum liquid level in the bottle body 3 reaches a preset height, the liquid level detection device sends a signal to the central processing unit, and the central processing unit controls the negative pressure pump to suspend operation.

[0036] A sputum suction control device provided by an embodiment of the present application includes: a storage bottle, a fixing device, a liquid level detection device, and a central processing unit; the storage bottle includes a bottle body, a first connecting pipe and a second connecting pipe respectively connected to the bottle body, the first connecting pipe is used to connect a negative pressure pump, and the second connecting pipe is used to connect a sputum suction pipe; the fixing device includes a first fixing frame, a second fixing frame, a telescopic part, a first abutting part connected to the first fixing frame, and a second abutting part connected to the second fixing frame, the first fixing frame is connected to the first abutting part through the telescopic part, and / or the second fixing frame is connected to the second abutting part through the telescopic part, and the telescopic part is used to adjust the distance between the first abutting part and the second abutting part; the liquid level detection device is arranged on the fixing device and is used to detect the sputum liquid level in the bottle body; the central processing unit is respectively communicatively connected to the negative pressure pump and the liquid level detection device. By arranging the liquid level detection device, the sputum liquid level can be detected, so that medical staff do not need to pay attention in real time whether the storage bottle is full, nor is it necessary to set up a buffer bottle to prevent sputum from entering the negative pressure pump, which can effectively reduce the occupied space of the device, reduce the workload of medical staff and the risk of damage to the negative pressure pump. In addition, the telescopic part can adjust the distance between the first abutting part and the second abutting part, which is convenient for adapting to storage bottles of different sizes.

[0037] Based on the above embodiment, Figure 3 It is a partial view of the first sputum suction control device provided by an embodiment of the present application. As Figure 3 shown, the telescopic part of the embodiment of the present application includes a first connecting rod 10, a spring 11 and a first limiting part 12. The first end of the first connecting rod 10 is connected to the first abutting part 8. A first through hole is provided on the first fixing frame 6. The second end of the first connecting rod 10 passes through the first through hole, and the first connecting rod 10 can slide relative to the first through hole. The first limiting part 12 is arranged on the circumferential surface of the first connecting rod 10. The spring 11 is sleeved on the first connecting rod 10, and both ends of the spring 11 respectively abut against the first fixing frame 6 and the first limiting part 12. The second fixing frame 7 is connected to the second abutting part 9. Among them, the diameter of the spring 11 is smaller than the diameter of the first through hole and the diameter of the first limiting part 12, and the first limiting part 12 is arranged close to the first end of the first connecting rod 10.

[0038] The first end of the first connecting rod 10 can be fixedly connected to the first abutting part 8. The first limiting part 12 can be a nut, and the nut can be threadedly connected to the first connecting rod 10 to be sleeved on the circumferential surface of the first connecting rod 10. The spring 11 is always in a compressed state, and the restoring force of the spring 11 is used to make the first abutting part 8 and the second abutting part 9 tightly abut against the bottle body of the bottle body 3 to firmly fix the bottle body 3. As Figure 1 shown, pull the first connecting rod 10 to the left to make the first abutting part 8 away from the second abutting part 9, so as to adapt to different storage bottles. Further, a pull ring 13 is connected to the second end of the first connecting rod 10. By arranging the pull ring 13, the first connecting rod 10 can be conveniently stretched. Figure 4This is a partial view of the second sputum suction control device provided by the embodiment of the present application. As Figure 4 shown, the second abutting portion 9 is directly connected to the second fixing frame 7. Specifically, the second abutting portion 9 and the second fixing frame 7 can be connected by bolts and nuts. The telescopic portion mainly adopts a spring structure, with relatively low cost.

[0039] Based on the above embodiments, the liquid level detection device of the embodiment of the present application includes an infrared emission probe 14 and an infrared reception probe 15. The infrared emission probe 14 is set on the first fixing frame 6 with adjustable height, and the infrared reception probe 15 is set on the second fixing frame 7 with adjustable height.

[0040] The infrared emission probe 14 intermittently emits infrared signals. When the infrared reception probe 15 receives the infrared signal, it indicates that the sputum has not reached the set liquid level. When the sputum reaches the set liquid level, since the sputum in the bottle is relatively turbid, it will block the infrared reception probe 15 from receiving infrared light. When the infrared reception probe 15 cannot receive the infrared signal, it will feedback this state to the central processing unit. The central processing unit will determine that the storage bottle is full and then suspend the operation of the negative pressure pump. In addition, it may further include a human-computer interaction module, which may include a touch screen. After the central processing unit determines that the storage bottle is full, it generates an alarm prompt and sends it to the touch screen of the human-computer interaction module to prompt the medical staff to clean the storage bottle. In addition, the infrared emission probe 14 and the infrared reception probe 15 are respectively set on the first fixing frame 6 and the second fixing frame 7 with adjustable positions, and the height of the set liquid level can be adjusted according to actual needs.

[0041] Based on the above embodiments, Figure 5 This is a left view of a sputum suction control device provided by the embodiment of the present application. Figure 6 This is a right view of a sputum suction control device provided by the embodiment of the present application. As Figure 5 and Figure 6 shown, a connecting plate 17 is connected to the first fixing frame 6 of the embodiment of the present application. A plurality of positioning holes 22 are provided at intervals in the height direction between the connecting plate 17 and the second fixing frame 7. The positioning holes 22 on the connecting plate 17 and the positioning holes 22 on the second fixing frame 7 are arranged in one-to-one correspondence. The infrared emission probe 14 is selectively connected to the positioning holes 22 on the connecting plate 17, and the infrared reception probe 15 is selectively connected to the positioning holes 22 on the second fixing frame 7.

[0042] The infrared emission probe 14 and the infrared reception probe 15 can be connected to the positioning holes 22 by bolts. On the basis that the first fixing frame 6 is connected to the first abutting part 8 through the telescopic part, if the positioning holes 22 are directly arranged on the first fixing frame 6, the distance between the bottle body and the first fixing frame 6 will change with the telescopic movement of the telescopic part, which will cause the distance between the infrared emission probe 14 and the bottle body to be relatively far. In this regard, a second through hole is provided on the connecting plate 17, and the connecting plate 17 is sleeved on the first connecting rod 10 through the second through hole. The first limiting part 12 is located between the connecting plate 17 and the spring 11. A third through hole is provided on the first fixing frame 6. The first end of the second connecting rod 18 is connected to the connecting plate 17, and the second end of the second connecting rod 18 penetrates through the third through hole, and the second connecting rod 18 can slide relative to the third through hole. A second limiting part 19 is provided on the second connecting rod 18. When the second limiting part 19 abuts against the outside of the first fixing frame 6, the spring 11 is in a compressed state. Based on the above setting method, when the distance between the first abutting part 8 and the second abutting part 9 changes, the distance between the infrared emission probe 14 and the bottle body remains unchanged. Among them, the second limiting part 19 can be a nut, and the nut is sleeved on the second connecting rod 18 by threads. When the second limiting part 19 abuts against the outside of the first fixing frame 6, the spring 11 is in a compressed state. By providing the second connecting rod 18 and the second limiting part 19, on the one hand, the connecting plate 17 can be fixed, and on the other hand, the spring 11 can always be in a compressed state, which also limits the minimum distance between the first abutting part 8 and the second abutting part 9.

[0043] Based on the above embodiments, on the basis that the second fixing frame 7 is directly connected to the second abutting part 9, a touch switch 20 is provided on the inner side of the second fixing frame 7 in the embodiment of the present application. The touch switch 20 is used to detect whether the storage bottle is installed in place, and the touch switch 20 is communicatively connected to the central processing unit.

[0044] When the storage bottle is installed in place, the button of the touch switch 20 will be squeezed, and the touch switch 20 is in the off state. After the central processing unit detects that the touch switch 20 is turned on, it determines that the storage bottle has been placed, and prompts on the human-computer interaction module that the storage bottle is placed in place; when the touch switch 20 is in the on state, after the central processing unit detects the on state, it will prompt on the human-computer interaction module that the storage bottle is abnormal. By providing the touch switch 20, it is convenient to detect whether the storage bottle is installed in place.

[0045] Based on the above embodiments, as Figure 4 shown, the embodiment of the present application further includes a hollow tube 16. One end of the hollow tube 16 is connected to the receiving end of the infrared reception probe 15, and the other end of the hollow tube 16 abuts against the bottle body 3.

[0046] The purpose of setting the hollow tube 16 is to prevent the influence of other light sources such as sunlight on the infrared receiving probe 15, ensuring that the received light mainly comes from the infrared transmitting probe 14 on the left. Additionally, the hollow tube 16 can be a plastic part.

[0047] Based on the above embodiments, the first abutting portion 8 and the second abutting portion 9 of the present application embodiment are arc-shaped elastic members, and an anti-wear pad is provided on the inner side of the arc-shaped elastic member.

[0048] The first abutting portion 8 and the second abutting portion 9 have a certain amount of deformation. The arc-shaped elastic member can hold the body of the storage bottle by deforming and fit well with the body of the bottle, facilitating the fixation of the storage bottle. An anti-wear pad is provided on the inner side of the arc-shaped elastic member. The anti-wear pad can be made of silica gel material, which will not damage the bottle body 3 and has a protective effect on the bottle body 3.

[0049] Based on the above embodiments, the first fixing frame 6 and the second fixing frame 7 of the present application example include a fixing rod and a support seat. The fixing rod and the support seat are integrally connected to form an L-shaped fixing frame. A reinforcing rib 21 is connected between the fixing rod and the support seat, and a screw hole is provided on the support seat.

[0050] By setting the reinforcing rib 21, the firmness of the first fixing frame 6 and the second fixing frame 7 can be increased. A screw hole is provided on the support seat, and the screw hole can be used to cooperate with a bolt to fix the first support base at a predetermined position.

[0051] For easy understanding, the following introduces the usage method of the sputum suction control device.

[0052] Install the storage bottle between the first abutting part 8 and the second abutting part 9. Under the action of the restoring force of the spring 11, the first abutting part 8 and the second abutting part 9 fix the storage bottle. The touch switch 20 detects whether the storage bottle is placed in place. The central processing unit detects the state of the touch switch 20 in real time. When no storage bottle is placed between the first abutting part 8 and the second abutting part 9, the touch switch 20 is in the open state. After the central processing unit detects the open state, it will prompt an abnormality of the storage bottle on the screen of the human-computer interaction module. When the storage bottle is placed, the storage bottle will squeeze the touch switch 20 to make the touch switch 20 in the closed state. When the central processing unit detects that the touch switch 20 is turned on, it determines that the storage bottle is installed in place, and the screen of the human-computer interaction module prompts that the storage bottle is placed in place. After the storage bottle is placed in place, the central processor controls the negative pressure pump to work and periodically controls the infrared emission probe 14 to send infrared signals. When the sputum in the storage bottle is lower than the position of the probe, the infrared receiving probe 15 will receive the infrared signal. After the signal is captured by the central processing unit, it is considered that the sputum in the storage bottle is not full and the system can operate normally. When the height of the sputum in the storage bottle is higher than the infrared receiving probe 15, due to the refraction of infrared light by the sputum and the blocking effect of the liquid turbidity on the infrared rays, the infrared receiving probe 15 cannot receive the infrared light. After the central processing unit detects this state, it prompts the medical staff to clean the liquid storage tank on the screen of the human-computer interaction module and controls the negative pressure pump to pause working.

[0053] The central processing unit controls the infrared emission probe 14 to periodically send infrared rays at a cycle of 1 second. Infrared rays are sent for 100 - 200 ms in each cycle. This time is the sending time obtained by comprehensively considering various factors such as the transparency of the storage bottle material used, the distance between the emission probe and the receiving probe, etc. If the sending time is too long, it will shorten the service life of the infrared probe. If the sending time is too short, even if there is no sputum in the storage bottle, the receiving probe will not be triggered, resulting in the failure of liquid level detection.

[0054] The sputum suction control device of this application can be adapted to storage bottles of different sizes, increasing the product matching; it can adjust the alarm liquid level of the storage bottle; it can detect the sputum liquid level of the storage bottle and give corresponding reminders and controls. Only one storage bottle is needed to achieve a very safe sputum suction function. There is no need for medical staff to pay attention in real time whether the storage bottle is full, nor is it necessary to set up a buffer bottle to prevent sputum from entering the negative pressure pump, which can effectively reduce the occupied space of the device, reduce the workload of medical staff and the risk of negative pressure pump damage.

[0055] The above has provided a detailed introduction to a sputum suction control device of the present application. The various embodiments in the specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. For the same or similar parts among the various embodiments, reference can be made to each other. It should be noted that for those of ordinary skill in the art in the technical field, without departing from the principle of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.

[0056] It should also be noted that in this specification, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including one..." does not exclude the existence of another identical element in the process, method, article or device including the said element.
