Technical Field
[0001] The utility model relates to the technical field of medical devices, and more particularly to an oral and nasal suction head for removing excessive or retained mucus in the oral or nasal cavity by means of suction. Background Art
[0002] Oral and nasal suction refers to removing excessive or retained mucus in the patient's oral or nasal cavity by means of suction, especially a common nursing means for patients with respiratory dysfunction or diseases and neurological dysfunctions clinically.
[0003] The current suction method is difficult to penetrate into the relatively narrow cavity during the suction process, and it is easy to damage the cavity and cause injury during the suction process. In addition, due to the relatively frequent demand for this suction process, if it is simply cleaned and placed randomly after single use, it may be contaminated. During the suction operation, it is difficult to master, inconvenient to control and sense its direction and angle. Some operators need to operate the suction device with both hands, or, when adjusting, they need to cooperate with both hands, and sometimes there is also a situation where the suction device slips when being taken. Summary of the Utility Model
[0004] In order to solve the above problems, the utility model provides an oral and nasal suction head that can penetrate into the nasal cavity and oral cavity and is not easy to damage the mucosa, and is equipped with a protective cover to protect it from contamination. The handle can be held with one hand, which is conducive to operation.
[0005] According to one aspect of the utility model, an oral and nasal suction head is provided, which includes a longitudinally arranged tube body part and a handle part communicated with the tube body part;
[0006] A first channel is longitudinally and continuously arranged in the tube body part. The tube body part has a flexible tip that gradually tapers towards the proximal end with a taper angle. The flexible tip is soft and can be bent for operation. The first channel forms a suction port at the proximal end of the flexible tip;
[0007] A second channel is longitudinally and continuously arranged in the handle part. The distal end of the handle part has a suction tube joint for connecting the pipeline of the suction device, and the proximal end of the handle part has a tube body joint for connecting with the tube body part. The first channel and the second channel are communicated to form a suction channel for fluid suction. The handle part is provided with a suction control hole communicated with the second channel. The suction control hole is manually blocked or unblocked to control the fluid suction process;
[0008] The handle part has a holding part that can be held with one hand. The holding part is located between the suction tube joint and the tube body joint. The holding part has clamping surfaces on both sides to form a non-cylindrical outer shape structure. The suction control hole is located in the holding part, and the orifice of the suction control hole is located on the top surface of the holding part.
[0009] Thus, the suction tube connector of the mouth and nose suction head is connected to the pipeline of the suction device. The suction port, the first channel, and the second channel form a suction channel for fluid suction. During the suction process, the operator holds the holding part of the handle part with one hand, and the thumb can control the suction force of negative pressure by pressing the suction control hole to block, completely unblock, or partially unblock it, manually and real-time control the suction process, improve safety, and the proximal end of the tube body part is a relatively soft flexible tip, which can further prevent damage to the mucosa; the holding part of the handle part, the overall structure of the holding part is non-cylindrical, which is convenient for the operator to hold with one hand, and is convenient for perceiving and controlling the direction of the proximal end of the mouth and nose suction head, which is beneficial to the operation.
[0010] In some embodiments, the bottom surface of the holding part has an arc surface, and both sides of the arc surface are connected to the bottoms of the two clamping surfaces on both sides. Thus, it can prevent the operator's hand from being overly squeezed when holding the handle part for a long time, and improve the comfort of the operator.
[0011] In some embodiments, a plurality of holding grooves are provided on both clamping surfaces on both sides, and the holding grooves extend to the arc surface. Thus, the design of the holding grooves conforms to the force application positions of the remaining fingers and the palm except the thumb during the holding action. While facilitating the operation, it can reduce the possibility of the mouth and nose suction head slipping off, and can also improve the operator's perception of the mouth and nose suction head.
[0012] In some embodiments, the top surface of the holding part has a structure with a high proximal end and a low distal end, and a chamfer is provided at the orifice of the suction control hole. Thus, it conforms to the upward curvature of the front end of the thumb. In addition to improving the comfort, the chamfer at the orifice can also make the thumb fit better with the suction control hole when pressing, ensuring the reliability of pressing the suction control hole.
[0013] In some embodiments, the position of the bottom surface of the holding part near the suction tube connector is lower than the position near the tube head connector, so as to form a stepped structure and is provided with an arc transition section, and the holding groove is located at the end near the suction tube connector. Thus, the length of the holding part can be increased, which is convenient for operation. The design of the front high and rear low conforms to the ergonomic design during holding.
[0014] In some embodiments, the tube body part includes a first part, a second part, and a third part connected in sequence. The first part is a flexible tip, the second part is a conical structure, the taper of the first part is smaller than that of the second part, the internal area of the second part and the first part gradually decreases towards the suction port, and the third part is connected to the tube connector by a buckle. Thus, the first part is the longest part, which is used to penetrate a longer channel, and the small taper of the first part is used to adapt to a narrower channel. The third part has the largest diameter, and the third part is connected to the tube connector by a buckle. This connection method is convenient and more economical, that is, the tube body part can be replaced separately to save costs.
[0015] In some embodiments, the third part of the tube body portion is sleeved outside the tube joint, and the end face of the holding portion adjacent to the tube joint abuts against the end face of the third part. Thus, this design can visually understand the assembly situation and ensure that the tube body portion and the handle portion are assembled in place.
[0016] In some embodiments, the mouth and nose suction head is configured with a shield, and the shield is sleeved outside the tube body portion. Thus, when not in use, the tube body portion can be protected from contamination or damage.
[0017] In some embodiments, the shield is connected with a protective cap, the protective cap is adapted to the inner diameter of the suction control hole, and the protective cap can be inserted into or pulled out relative to the suction control hole. Thus, when not in use, inserting the protective cap into the suction control hole can prevent contaminants from entering the suction control hole.
[0018] In some embodiments, the shield is connected with a collar for hanging the mouth and nose suction head. Thus, when not in use, the shield is sleeved outside the tube body portion, and the mouth and nose suction head is hung with the collar.
[0019] In some embodiments, the handle portion is made of a relatively hard plastic material, the tube body portion is made of a relatively soft plastic material, and the holding portion is provided with a plurality of weight-reducing grooves. Thus, by providing the weight-reducing grooves, the weight of the holding portion can be reduced, and the operating feel of the operator can be improved.

[0033] The present utility model will be further described below in conjunction with specific embodiments.
[0034] In this application, the end close to the patient is called the proximal end, and the end close to the operator (medical staff) is called the distal end. Using the mouth and nose suction head provided by this application, a mouth and nose suction head for removing excessive or retained mucus in the oral or nasal cavity through suction means can also be used to perform flushing operations on the oral cavity, nasal cavity, or other deep and narrow tissue areas that require access in actual applications.
[0035] Example 1
[0036] As Figures 1 to 3 shown, a mouth and nose suction head of an embodiment of the present utility model includes a longitudinally arranged tube body part 1 and a handle part 2 communicated with the tube body part 1. The handle part 2 is made of a relatively hard plastic material, and the tube body part 1 is made of a relatively soft plastic material.
[0037] As Figure 4As shown, the tube body portion 1 has a first channel 10 that runs longitudinally through it. The tube body portion 1 has a flexible tip that tapers towards the proximal end (i.e., the front end of the tube body portion 1) at a taper angle. The flexible tip is soft and bendable for operation. The first channel 10 forms a suction port 101 at the proximal end of the flexible tip. The proximal end of the tube body portion 1 is a relatively soft flexible tip, which can prevent damage to the mucosa.
[0038] As Figure 6 shown, the handle portion 2 has a second channel 20 that runs longitudinally through it. The distal end of the handle portion 2 has a suction tube connector 23 for connecting a suction device pipeline (not shown in the figure). The proximal end of the handle portion 2 has a tube body connector 21 for connecting to the tube body portion 1. There is a gripping portion 22 that can be held with one hand between the suction tube connector 23 and the tube body connector 21. The handle portion 2 is connected to the tube body portion 1, and the first channel 10 and the second channel 20 are connected to form a suction channel for fluid suction. The handle portion 2 is provided with a suction control hole 24 that communicates with the second channel 20. The operator presses the orifice of the suction control hole 24 to manually block or unblock the suction control hole 24 to control the fluid suction process.
[0039] Specifically, as Figure 5 and 6 shown, the gripping portion 22 has two side clamping surfaces 221 to form a non-cylindrical outer shape structure. The suction control hole 24 is located within the gripping portion 22, and the orifice of the suction control hole 24 is located on the top surface 223 of the gripping portion 22. In this embodiment, the main body of the clamping surface 221 is a vertically symmetric surface. In practical applications, it can also be a vertically slightly inclined symmetric surface, or other non-cylindrical outer shape structures.
[0040] As Figure 5 and 7 shown, the bottom surface of the gripping portion 22 has an arc surface 222, and both sides of the arc surface 222 are connected to the bottom of the two side clamping surfaces 221. The bottom surface of the gripping portion 22 and the two side clamping surfaces 221 have a smooth transition, which can prevent the hand from being overly squeezed when the operator holds the handle portion 2 for a long time, improving the operator's comfort.
[0041] Both of the two side clamping surfaces 221 are provided with a plurality of gripping grooves 224, and the gripping grooves 224 extend to the arc surface 222. The design of the gripping grooves 224 conforms to the force application positions of the remaining fingers and the palm except the thumb during the gripping action. While using the operation, it can reduce the possibility of the mouth and nose suction head slipping off, and can also improve the operator's perception of the mouth and nose suction head.
[0042] The top surface 223 of the holding part 22 has a structure where the proximal end is high and the distal end is low, which conforms to the upward curvature of the front end of the thumb. A chamfer 241 is formed at the orifice of the suction control hole 24. Besides improving comfort, it also makes the thumb fit better with the suction control hole 24 during pressing, ensuring the reliability of pressing the suction control hole 24.
[0043] The holding part 22 of the handle part 2 has a non-cylindrical overall structure, which is convenient for the operator to hold with one hand, and is also convenient for perceiving and controlling the direction of the proximal end of the nose and mouth suction head, facilitating operation.
[0044] To reduce the weight of the holding part 22 and improve the operating feel of the operator, a plurality of weight reduction grooves 25 can be provided on the surface of the holding part 22 ( Figure 5 and Figure 11 as shown).
[0045] As Figure 4 shown, the tube body part 1 specifically includes a first part 11, a second part 12, and a third part 13 that are connected in sequence. The outer shapes of the first part 11 and the second part 12 are both tapered structures, and the inner diameters of the first part 11 and the second part 12 are also tapered structures. The first part 11 is the flexible tip, and the taper of the first part 11 is smaller than that of the second part 12. The second part 12 and the first part 11 gradually decrease in internal area towards the suction port 101. The first part 11 is the longest part and is used to penetrate a longer channel, and the small taper of the first part 11 is to adapt to a narrower channel. The third part 13 has the largest diameter, and the third part 13 is connected to the tube joint 21 by a snap connection. Specifically, the third part 13 of the tube body part 1 is sleeved outside the tube joint 21. The outer wall of the third part 13 is cylindrical, and the inner wall of the third part 13 has a protruding snap male buckle 131, and the outer wall of the tube joint 21 has an inwardly recessed snap female buckle 211 ( Figure 5 as shown), and the snap male buckle 131 and the snap female buckle 211 are adapted. After the third part 13 is connected to the tube joint 21, the end face of the holding part 22 against the tube joint 21 abuts against the end face of the third part 13.
[0046] As Figure 3 shown, the third part 13 and the tube joint 21 are connected by a snap connection. This connection method is convenient and more economical, that is, the tube body part 1 can be replaced separately to save costs. And the design that the end face of the third part 13 abuts against the front end of the holding part 22 can visually understand the assembly situation and ensure that the tube body part 1 and the handle part 2 are assembled in place.
[0047] The oral and nasal suction head can be equipped with a shield 3, which is sleeved outside the tube body 1 (as shown in 3). When not in use, the tube body 1 can be protected from being contaminated or damaged. In this embodiment, the shield 3 is adapted to the third portion 13 of the tube body 1, and when the shield 3 is assembled, it conflicts with the front end of the grip 22.
[0048] like Figure 1 and 3 As shown, the shield 3 is connected to a protective cap 31, and the protective cap 31 is adapted to the inner diameter of the suction control hole 24, and the protective cap 31 can be inserted into the suction control hole 24 or pulled out relative to the suction control hole 24. When not in use, the protective cap 31 is inserted into the suction control hole 24 to prevent pollutants from entering the suction control hole 24. In addition, the shield 3 is connected to a ring 32 for hanging the oral and nasal suction head. When the hanging conditions are met, when not in use, the shield 3 is sleeved outside the tube body part 1, and the oral and nasal suction head is hung with the ring 32. The shield 3, its protective cap 31 and the ring 32 adopt an integrated structure.
[0049] When the oral and nose suction head is not in use, the shield 3 is sleeved outside the tube body portion 1, and the protective cap 31 is inserted into the suction control hole 24 to protect the oral and nose suction head from pollution or damage. In addition, under the hanging condition, it can be suspended by the collar 32 and placed.
[0050] When the oral and nasal suction head is in use, the oral and nasal suction head is connected to the suction tube (not shown) of the external suction device through the suction tube connector 23 at the far end. The protective cap 31 needs to be withdrawn from the suction control hole 24, the protective cover 3 and the tube body 1 of the oral and nasal suction head are separated, and the suction device is adjusted to an appropriate pressure. At this time, the suction port 101, the first channel 10 and the second channel 20 form a suction channel for fluid suction. During the suction process, the operator holds the gripping portion 22 of the handle portion 2 with one hand, and the thumb covers and controls the suction control hole 24, and blocks or completely unblocks or partially unblocks to control the force of negative pressure suction, and manually controls the suction process in real time. Intermittent suction is performed to the target oral and nasal cavity through the tube body 1. When controlling the suction control hole 24, the suction is stopped when the thumb moves away from the suction control hole 24, and the suction is started after the thumb covers and controls the suction control hole 24. After use, the oral and nasal suction head is cleaned and placed in the protective cover 3 again.
[0051] Example 2
[0052] The main difference between the present embodiment 2 and the embodiment 1 is that the handle part 2 is different. Specifically, Figures 9 to 12 As shown, in this embodiment, the bottom surface of the gripping portion 22 is not at the same horizontal height, but the bottom surface of the gripping portion 22 at one end near the suction pipe joint 23 is lower than the bottom surface at one end near the pipe head joint, forming a step-like structure, and the high and low connection has an inclined arc-shaped transition section 225, and the gripping groove 224 is located at one end near the suction pipe joint 23.
[0053] The top surface 223 of the holding portion 22 is also structured such that it is higher at the proximal end and lower at the distal end, conforming to the upward curvature of the tip of the thumb. The orifice of the suction control hole 24 is located on the top surface 223 of the holding portion 22. An indented thumb placement groove 242 is provided on the top surface 223, and the thumb placement groove 242 surrounds the orifice of the suction control hole 24. During operation, the operator holds the holding portion 22 with one hand, and presses the suction control hole 24 with the thumb within the thumb placement groove 242.
[0054] The holding portion 22 of the handle part 2 in this embodiment is lengthened relative to the holding portion 22 in Embodiment 1 and adopts a design that is higher at the front and lower at the back. The entire handle part 2 conforms to the ergonomic design during holding, which facilitates operation.
[0055] With the present utility model, the suction tube joint 23 enables quick external connection to a device. The tube body part 1 can easily penetrate into narrow areas, and the tube body part 1 is made of a soft material to avoid damaging the oral and nasal passages. The holding portion 22 of the handle part 2 adopts an ergonomic design, facilitating single-handed holding and operation by the operator. This not only improves the comfort of the operator but also enhances the perception of operation. The operator can better adjust the direction of the suction head and effectively control the suction control hole 24 in real time, improving the safety of operation. The tube body part 1 and the handle part 2 are of a split structure and are connected by a snap fit, allowing the tube body part 1 to be replaced separately, reducing medical costs. The oral and nasal suction head is equipped with a shield 3, and the shield 3 is also provided with a protective cap 31 adapted to the suction control hole 24 and a hanging loop 32. When not in use, it can effectively protect the oral and nasal suction head from contamination.
[0056] The above are only some embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the creative concept of the present utility model, other deformations and improvements can be made, and these all fall within the protection scope of the present utility model.
