Description

A nasopharyngeal tumor radiotherapy flushing device

Technical field

The utility model relates to the technical field of medical flushing devices, in particular to a nasopharyngeal tumor radiotherapy flushing device.

Background technique

In the traditional sense, nasal irrigation requires the patient to sit by the pool, hang the nasal irrigator slightly above the top of the head, or at the same level as the top of the head, place the olive head of the nasal irrigator in the nasal vestibule area, and pinch the plastic bottle with your hands. Or turn on the switch of the nasal irrigator electrically, open your mouth and breathe naturally, and let the cleaning solution such as saline flow into one nostril, and then flow out from the opposite nostril or mouth.

Patients with nasopharyngeal tumors have put forward higher requirements for nasal irrigation, which are mainly reflected in the following aspects: First, due to the need for more timely and thorough cleaning and care during the treatment process, requirements are placed on the intensity of cleaning during the cleaning process. The existing nasal cavity Regardless of whether the irrigator is used for manual or electric flushing, the single flushing intensity of the lotion coming out of the flushing port is the same. Even if the electric flushing method can accurately adjust the flushing intensity, the nasal lining of this type of patient will become more severe due to nasopharyngeal lesions or surgery. It is fragile and does not have a good cleaning effect when the flushing intensity is low. Once the intensity is increased, it can easily cause damage to the lining of the nasopharynx, which adds a psychological burden to the patient every time. Secondly, the existing nasal irrigators are generally It has an integrated structure, that is, the rinsing head and the bottle used to store cleaning fluid are connected in one piece. It is inconvenient to use. Either as mentioned before, the nasal irrigator needs to be hung externally, or the patient or medical staff must carry it manually, which is time-consuming and labor-intensive. , the flushing effect is limited; in addition, the flushing tube head of the existing nasal irrigator is generally a fixed-shaped hard flushing tube, which is integrally connected with the flushing bottle body, which not only consumes a lot of materials, but also has certain limitations when used by the patient, and the patient experience is not good. It is good, and the flushing fluid easily flows out from the nostril where the flushing tube head enters. Because it does not better contact the nasopharynx, the cleaning fluid is wasted and the cleaning effect is reduced.

In view of the existing problems in the prior art, this application improves and obtains a new type of nasopharyngeal tumor radiotherapy flushing device.

When in use, the operator places the suction cup seat 3 of the device on a pool or a facility outside the sink, removes the cylindrical holding part 8 from the hanging ring 20 position, and first opens the first pump body 6 to flush the flushing pipe 9 The liquid flow rate can be adjusted specifically through the flow control valve 10, so that the strength of the liquid discharged from the flushing head 12 is visually appropriate, so that during subsequent flushing, the flow rate can be appropriately increased according to the flushing situation; or, as required by the doctor. Adjust, temporarily close the first pump body 6 after adjustment; open the second pump body 7 to supply liquid to the liquid storage bottle of the atomizer 14, open the first switch 24, and start the atomizer 14 to work. At this time, the annular groove The atomizer outlet at position 18 discharges atomized gas in a ring. The operator holds the cylindrical holding part 8 and gradually inserts the flushing elbow 11 into one nostril. The nasal cavity is moistened by the atomized gas until the flushing head reaches the nasopharynx. After the patient feels comfortable, the atomized gas moisturizes the mucous membrane of the nasopharynx, and then continues to open the first pump body 6; at this time, the patient tilts the head and keeps the nostrils tilted slightly upward, on the one hand, the flushing liquid can be more It is best to flow from the nasopharynx to the other nostril or mouth, and on the other hand, avoid the flushing fluid from flowing back downward or accumulating in the nostril. The liquid in the liquid storage cylinder 1 enters the flushing elbow 11 through the flushing pipeline 9, and continues to be discharged from the liquid outlet on the flushing head 12 to flush the patient's nasopharynx. During this process, due to the presence of atomized gas, it The flushing liquid is mixed. When the flushing fluid reaches the nasopharyngeal wall, the nasal mucosa has been covered to form a protective film. Compared with flushing the liquid directly, the discomfort of patients with nasopharyngeal tumors is reduced. According to the patient's feeling or speculum observation during the flushing process, the flow of flushing liquid can be continued to be increased through the flow control valve 10 to enhance the cleanliness and thoroughness of flushing; the flushing waste liquid is gradually discharged from the patient's other nostril or mouth; continue Perform the same operation as above, switch to the other nostril and perform nasopharyngeal irrigation.

During the flushing process, the amount of flushing fluid can be understood according to the change of the liquid level on the liquid storage cylinder 1 to ensure sufficient flushing. Since the operator uses the cylindrical holding part separated from the cylinder base 2 to perform the flushing operation, medical staff or other personnel can promptly replenish the flushing fluid through the liquid filling port 4 on the liquid storage cylinder 1, avoiding the need for existing flushers. It is troublesome to add fluid after the patient stops the flushing operation.

Example 2

As shown in Figure 7, the structure of the nasopharyngeal tumor radiotherapy irrigation device is the same as that of the irrigation device in Embodiment 1. The difference is that spiral ridges with gradually increasing outer diameters are provided on the outer wall of the irrigation elbow from top to bottom. 26. An annular ridge 27 is provided on the outer wall of the flushing elbow at the bottom end of the spiral ridge. The gradually increasing outer diameter of the spiral ridges is more in line with the changes in the nasal passages, and the use effect is more effective.

By arranging spiral convex strips and annular convex strips, the gap between the flushing elbow and the inner wall of the patient's nasal cavity can be reduced, thereby avoiding the problem of waste and reduced flushing effect caused by the flushing fluid flowing directly back out of the nostrils to be flushed quickly during the flushing process. It is more suitable for operators who are inexperienced or have slightly larger nostrils.

The above-mentioned specific embodiments cannot be used to limit the protection scope of the present utility model. For those skilled in the art, any substitutions, improvements or transformations made to the embodiments of the present utility model fall within the protection scope of the present utility model.

The parts not described in detail in the present invention are all well-known technologies to those skilled in the art.
