Description

Technical Field

[0001] The utility model belongs to the technical field of nursing consumables, and particularly relates to a two-section negative pressure sputum suction tube. Background Art

[0002] A sputum suction tube is a component used to suck sputum. When performing sputum suction, the actions of nursing staff should be as gentle as possible to avoid damaging the patient's tissues. Sputum suction tubes are widely used in both medical and household settings.

[0003] There are two types of sputum suction tubes, a silicone soft tube and a hard tube, with suction holes at the end. The hard sputum suction tube is more common in home care and is used for oral care. It needs to be cleaned and can not only suck sputum but also suck the cleaning liquid for oral cleaning. The sputum suction tube is used in conjunction with a manual or electric negative pressure device. The sputum suction tube is connected to a liquid storage tank, and sputum suction is performed by manually generating negative pressure and sucking it into the liquid storage tank.

[0004] For this conventional structure sputum suction tube, there are currently some problems: First, since there is still a relatively long flexible tube connecting the sputum suction tube and the liquid storage tank, when sucking clear sputum, due to the long pipeline, a small amount of sputum is difficult to suck out; Second, currently, all sputum suction tubes are one-piece and integral structures, and the long length is not convenient for cleaning after sputum suction. Content of the Utility Model

[0005] In view of the above problems, the purpose of the utility model is to provide a two-section negative pressure sputum suction tube, aiming to solve the above technical problems.

[0006] The utility model adopts the following technical solutions:

[0007] The two-section negative pressure sputum suction tube includes a front tube and a tail tube. A buffer part is further arranged at the rear part of the front tube. There is a buffer cavity in the buffer part. One end of the buffer part also has a connection hole, and the connection hole is coaxially arranged with the front tube. The rear end of the front tube is located in the buffer cavity, and the front end of the tail tube is hermetically inserted into the rear end of the front tube from behind the connection hole.

[0008] Further, there are multiple circles of sealing rings on the inner wall of the connection hole. The rear end of the front tube forms a guiding end with an outer diameter smaller than that of the front tube, and the front end of the tail tube forms a receiving section.

[0009] Further, the front section of the front tube has a conical head. A number of triangular holes are evenly opened on the outer wall of the conical head, and there is also a small round hole at the top of the conical head.

[0010] Further, there are also scale marks on the surface of the tail tube.

[0011] The beneficial effects of the present utility model are as follows: In the structural design of the present utility model, the sputum suction tube is divided into two sections, namely the front tube and the tail tube, and a buffer part is provided at the rear part of the front tube. This sputum suction tube has two usage methods. When used normally, the tail tube is inserted into the front tube to form a whole, and sputum can be directly sucked. If there is still a small amount of sputum that cannot be normally sucked, the tail tube is pulled backward a certain distance to separate it from the front tube, so that the small amount of sputum can also enter the buffer part through the front tube. After the sputum suction operation is completed, the tail tube is removed, and the sputum suction tube is divided into two sections, which is more convenient for cleaning when separated and washed.

[0014] Figure 3 is a structural diagram of the buffer part;

[0015] Figure 4 is a structural diagram of the conical head. Detailed Embodiment

[0016] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the following further details the present utility model in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0017] In order to illustrate the technical solutions described in the present utility model, the following is illustrated through specific embodiments.

[0018] As Figures 1-3 shown, the two-stage negative pressure sputum suction tube provided in this embodiment includes a front tube 1 and a tail tube 2. A buffer part 3 is further provided at the rear part of the front tube 1. There is a buffer cavity 31 in the buffer part 3. There is also a connection hole 32 at one end of the buffer part 3. The connection hole 32 is coaxially arranged with the front tube 1. The rear end of the front tube 1 is located in the buffer cavity 31. The front end of the tail tube 2 is hermetically inserted into the rear end of the front tube 1 from behind the connection hole 32.

[0019] When sucking sputum, we will find that when there is a large amount of sputum, the sputum suction tube can suck away most of the sputum. However, for the remaining small amount of sputum, especially the thinner sputum, due to the relatively long length of the sputum suction tube and the connection of a flexible tube at the tail, the sputum is less, and it is a manually operated negative pressure device with relatively weak adsorption force. Therefore, the remaining small amount of sputum can only be sucked to a small height in the sputum suction tube. The sputum cannot fill the diameter of the sputum suction tube, causing the sputum sucked to a small height to fall back, and this part of the sputum cannot be sucked out.

[0020] In this structure, the suction tube has two usage modes. When used normally, the tail tube is inserted into the front tube to form a whole, and it can directly suck sputum and be used as a normal suction tube. If there is only a small amount of sputum, or a small amount of remaining sputum cannot be sucked out, the tail tube is pulled backward a certain distance to separate it from the front tube. In this way, a small amount of sputum that can be sucked at a certain height will enter the buffer part through the front tube. Therefore, this buffer part also serves as a space for storing sputum. The space in the buffer part is not large, and the whole suction tube is made of transparent material, which does not affect the normal operation of the suction tube. During cleaning, the tail tube is removed, and the suction tube is divided into two sections. The cavity of the buffer part can be directly rinsed with water. Separated cleaning is more convenient and cleaner. In the figure, there are also scale marks 22 on the surface of the tail tube 2. There are two scale marks 22, which are used as the insertion depth mark and the retraction distance mark respectively.

[0021] In this structure, the tail tube is inserted into the buffer part. As a specific structure, there are multiple circles of sealing rings 33 on the inner wall of the connecting hole 32. The rear end of the front tube 1 forms a guiding end 11 with an outer diameter smaller than that of the front tube. The front end of the tail tube 2 forms a receiving section 21. The connecting hole is coaxial with the front tube and the tail tube, which can ensure alignment with the front tube when inserting the tail tube. The guiding end of the front tube matches the receiving section of the tail tube and can just fit and insert, and the sealing is good, so that sputum can be normally sucked. In addition, there are multiple circles of sealing rings on the inner wall of the connecting hole, which can seal the tail tube and provide a certain amount of friction to ensure that the tail tube does not loosen during operation.

[0022] In addition, as Figure 4 shown, the front section of the front tube 1 has a conical head 4. A number of triangular holes 41 are evenly opened on the outer wall of the conical head 4, and there is also a small round hole 42 at the top of the conical head 4. Setting the front section of the front tube 1 as conical can be more suitable for narrow areas and suck more cleanly.

[0023] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
