Description

Technical Field

[0001] The present invention relates to the technical field of vomitus collection devices, and in particular to a clinical vomitus collection device. Background Art

[0002] There are many patients with vomiting, gastric retention, and hematemesis due to upper gastrointestinal bleeding in the department of gastroenterology. Clinically, it is necessary to collect the vomitus of patients for occult blood tests and other examinations. In order to ensure the hygiene of the room during hospitalization, it is also necessary to collect the vomitus centrally. During the traditional collection of vomitus, disposable cups, plastic bags or trash cans are often used. For some patients with a relatively rapid onset of vomiting, it is very difficult to ensure that the collection device can be delivered to the patient's mouth at the first time of vomiting. Therefore, it is easy to get vomitus on clothes and quilt covers.

[0003] Of course, there are also special vomitus collection devices on the market, which are widely used for people prone to motion sickness. The main structure of the vomitus collection device for people prone to motion sickness is a rubber mouthpiece and a collection bag. Under normal conditions, the collection bag is in a compressed shape and is located in the annular rubber mouthpiece. When in use, the collection bag can be pulled or blown to make the collection bag maintain an inflated state, and the bag mouth of the collection bag is connected to the mouthpiece and is in an open state. During vomiting, the person aligns the mouth with the mouthpiece, and the vomitus can enter the collection bag. Although this kind of vomitus collection device can also be used for clinical vomitus collection, during its use, it must rely on the cooperation of both hands to align the mouthpiece with the mouth. For weak clinical patients, it is very difficult to hold the mouthpiece of the vomitus collection device with both hands or one hand to maintain alignment with the mouth. Therefore, the applicable effect of this vomitus collection device in clinical practice is also poor. Based on the above situation, it is necessary to design a clinical vomitus collection device to solve the above problems. Summary of the Invention

[0004] The present invention provides a clinical vomitus collection device. By providing a vomitus collection device composed of a collection bag, a mouthpiece, and a wearing component, it can be worn on the head position of the human body, and the mouthpiece can be kept always aligned with the mouth of the human body, thus solving the problem that the mouthpiece of the existing vomitus collection device is difficult to always align with the mouth of the human body.

[0005] The technical problems solved by the present invention are realized by the following technical solutions: A clinical vomitus collection device includes a collection bag for defining a storage space for accommodating vomitus and having a bag mouth as a vomitus input port, a mouthpiece that cooperates with the bag mouth position of the collection bag to keep the bag mouth in an open state, and a wearing component that is an installation carrier of the mouthpiece and is worn on the head position of the human body to keep the mouthpiece aligned with the mouth of the human body.

[0006] Preferably, the wearing component includes a headgear and a folding pad connected to the headgear by a restraint strap. The folding pad includes a horizontal pad that is located under the human mandible during wearing and a vertical pad that is integrally formed with the horizontal pad and is used to attach to the human face. The position of the mask opening is on the vertical pad and corresponds to the position of the human mouth.

[0007] Preferably, the restraint strap includes a towing rope and a towing rope effective length adjuster. The number of the restraint straps is at least two, and at least two of the restraint straps are symmetrically distributed on both sides of the folding pad and connected to the headgear.

[0008] Preferably, the mask opening is a columnar body with a hollow interior and two open ends.

[0009] Preferably, the position where the vertical pad covers the human face is not higher than the position of the human nose.

[0010] Preferably, the mask opening is detachably connected to the collection bag.

[0011] Preferably, one end of the mask opening that cooperates with the collection bag has a limiting ring protrusion, and an elastic band is arranged at the bag mouth position of the collection bag. The detachable connection between the collection bag and the mask opening is realized through the cooperation of the elastic band and the limiting ring protrusion.

[0012] Preferably, the wearing component includes a face mask and ear hanging straps on both sides of the face mask. The mask opening is on the face mask and corresponds to the position of the human mouth.

[0013] The beneficial effect of the present invention is that by providing a vomit collection device composed of a collection bag, a mask opening, and a wearing component, the vomit collection device can be worn on the head position of the human body, and the mask opening can be kept always aligned with the human mouth, thereby solving the problem that the mask opening of the existing vomit collection device is difficult to always align with the human mouth.

Detailed implementation manners

[0017] In order to make the technical means, creative features, achieved purposes and effects realized by the present invention easy to understand, the present invention will be further described below with reference to specific illustrations.

[0018] Refer to Figure 1 For the structure of the existing vomit collection device, where Figure 1 a is a schematic diagram of the collection bag 1 in a compressed state placed in the cover mouth 2, Figure 1 b is a schematic diagram of the collection bag 1 taken out from the cover mouth 2 in an expanded state. When a person has a vomiting sensation, align the cover mouth 2 in the state shown in Figure 1 b with the human mouth, and the vomit can pass through the cover mouth 2 and enter the collection bag 1. The existing cover mouth 2 is generally made of rubber, and the collection bag 1 is made of the same material as a common plastic bag. The above-mentioned vomit collection device is mainly applicable to people suffering from motion sickness. They have enough physical strength to hold the cover mouth 2 of the above-mentioned vomit collection device and align the cover mouth 2 with the human mouth. However, for various clinical patients, especially those in a weak physical state, they are unable to hold the above-mentioned vomit collection device for a long time. Even if medical staff or caregivers hold it on their behalf, it is still rather inconvenient. Based on the above, the vomit collection device cannot be widely used clinically. The present invention makes the following improvements to the existing vomit collection device.

[0019] A clinical vomitus collection device mainly consists of three main parts, namely a collection bag 1, a mouthpiece 2, and a wearing component 3. The main function of the collection bag 1 is the same as that of the collection bag 1 in the above-mentioned prior art, which is used to define a storage space for containing vomitus. The collection bag 1 has a bag opening 101 as an input port for vomitus to enter the internal storage space of the collection bag 1. The mouthpiece 2 is a columnar body with a hollow interior and openings at both ends. It can be made of plastic, rubber, or metal, ensuring that the internal hollow of the mouthpiece 2 remains stable when not under force (or under a small force). The wearing component 3 is an installation carrier for the mouthpiece 2, that is, the mouthpiece 2 can be installed on the wearing component 3 to ensure its stable position. When the wearing component 3 is worn on the human head, one end opening of the mouthpiece 2 should be aligned with the human mouth, and the other end opening of the mouthpiece 2 is in position cooperation with the bag opening 101 of the collection bag 1. When the bag opening 101 of the collection bag 1 is sleeved on the mouthpiece 2, the bag opening 101 of the collection bag 1 remains open. When vomiting, the vomitus passes through the mouthpiece 2 and enters the interior of the vomit bag, thus achieving collection. Since the mouthpiece 2 can always be aligned with the human mouth under the action of the wearing component 3 without the need for a person to hold the vomitus collection device, it is more suitable for clinical patients, especially for physically weak clinical patients.

[0020] Combined with the improved clinical vomitus collection device of the present invention described above, the following two specific embodiments are given here. The common point of the two specific embodiments is that they are both worn on the human head position to fix the mouthpiece 2 to the human mouth. The difference between the two specific embodiments lies in the different structural compositions of the wearing component 3.

[0021] Specifically, refer to Figure 2 、 Figure 4 、 Figure 5 and Figure 6, which is a first specific embodiment of a clinical vomit collection device provided by the present invention. In this embodiment, the wearing component 3 is a headgear and a folding pad 5 connected to the headgear through a restraint belt. In order to save materials, the headgear can be set to a hollow shape (such as various common mesh shapes, and its material can be rubber or conventional cloth material). The folding pad 5 includes two parts, namely a horizontal pad 502 supported on the bottom of the mandible when in use, and a vertical pad 501 integrally formed with the horizontal pad 502 for attaching to the human face. The installation position of the mask mouth 2 is on the vertical pad 501 and corresponds to the position of the human mouth. One end of the restraint belt is connected to the headgear and the other end is connected to the folding pad 5. The connection position of the other end with the folding pad 5 can be the horizontal pad 502 or the vertical pad 501, or both connected to the horizontal pad 502 and the vertical pad 501. The number of restraint belts should be at least two, and at least two restraint belts are symmetrically distributed on both sides of the headgear 4. Of course, there can be more than two. Four restraint belts are used as an example for illustration. When in use, the wearing component 3 of the first embodiment is worn in the following way: Figure 7 As shown, the headgear is worn at the top of the head, the horizontal pad 502 of the folding pad 5 is attached to the bottom of the human jaw, the vertical pad 501 is attached to the face of the human head, and the mask opening 2 on the vertical pad 501 is aligned with the mouth of the human body. The headgear applies tension to the folding pad 5 through the restraint belt. Under the action of the lower jaw, face and restraint belt, the folding pad 5 can be stably maintained in the wearing position, that is, the mask opening 2 is always kept aligned with the mouth of the human body. During vomiting, vomitus can pass through the mask opening 2 and enter the collection bag 1.

[0022] Furthermore, in the first embodiment, if Figure 8 As shown, the restraint belt includes a traction rope 6 and an effective length adjuster 7 for the traction rope 6. A method for implementing the traction rope 6 and the length adjuster 7 is given below. Specifically, the traction rope 6 is made of elastic rubber material (other elastic and stretchable materials can also be used). After being stretched, its diameter becomes smaller and its length becomes longer. When the stretched deformation is restored, the diameter of the traction rope 6 becomes larger and the length is shortened. The length adjuster 7 is a block with a perforation 701. The diameter of the perforation 701 is smaller than the diameter of the traction rope 6 in a normal state. When the traction rope 6 is stretched, the diameter of the traction rope 6 becomes smaller, and the traction rope 6 can pass through Perforation 701, when the stretching force is removed, the traction rope 6 recovers its deformation diameter and becomes larger, which contacts the inner wall of the perforation 701. The traction rope 6 forms a resistance force against the inner wall, generating friction, keeping the relative position of the traction rope 6 and the perforation 701 stable, thereby controlling the effective length of the traction rope 6. Of course, other length adjustment methods can also be used between the traction rope 6 and the length adjuster 7, for example, by winding and knotting the traction rope 6 on the length adjuster 7, the effective length of the traction rope 6 can be controlled. There are many other ways of coordinating the traction rope 6 and the length adjuster 7 in daily life, which will not be elaborated here.

[0023] In the first embodiment of the above-mentioned clinical vomit collection device, since the vomit of clinical patients has a pungent odor, in order to avoid strong irritation to the patients from this odor, the position where the vertical pad 501 in the folding pad 5 adheres to the human face should avoid covering the human nose, that is, the nose directly inhales air during the inhalation process. Preferably, the height of the position where the vertical pad 501 adheres to the human face should not be higher than the position of the human nose, that is, as Figure 7 shown, the attachment area of the vertical pad 501 is from the upper lip of the human body to the face at the position of the horizontal pad 502.

[0024] Furthermore, considering that during the clinical use process, the wearing component 3 can be reused, the connection relationship between the mask mouth 2 and the collection bag 1 should be set in a detachable manner, so that when there is a large amount of vomit in the collection bag 1, it is convenient to replace the new collection bag 1, and at the same time, the repeated use of the wearing component 3 can be ensured. Specifically, the detachable connection method between the mask mouth 2 and the collection bag 1 can be achieved in the following way. A limiting ring protrusion 201 is provided at one end of the mask mouth 2 that cooperates with the bag mouth 101 of the collection bag 1, and an elastic band 102 is provided at the position of the bag mouth 101 of the collection bag 1. When installing the collection bag 1 at the position of the mask mouth 2, the elastic band 102 is passed over the limiting ring protrusion 201 and hoop-mounted on the outer wall of the mask mouth 2, then the installation of the collection bag 1 can be realized. Of course, there are many ways to detachably install the collection bag 1 on the mask mouth 2, such as adhesive bonding, snap connection, etc., which will not be elaborated one by one here.

[0025] Refer to Figure 3 , the present invention also provides a second specific embodiment of the clinical vomit collection device. The difference between this embodiment and the second embodiment lies in the different structural compositions of the wearing component 3. The wearing component 3 is simpler in structure compared to the wearing component 3 of the first embodiment. The wearing component 3 of the second embodiment is a face mask 8 with hanging ear straps 9 on both sides. The face mask 8 with hanging ear straps 9 on both sides is similar to the structure of an existing mask. The difference between it and the structure of the existing mask is that a mask mouth 2 is provided at the position corresponding to the mouth of the face mask 8, and the mask mouth 2 is used to connect with the collection bag 1. During use, the patient wears it in the same way as a conventional mask, and then the mask mouth 2 can be stably positioned at the patient's mouth position.

[0026] Furthermore, as Figure 9 shown, in order to ensure that a person can breathe fresh air through the nose during vomiting, an avoidance groove 10 is provided at the position of the face mask 8 corresponding to the human nose. The avoidance groove 10 corresponds to the position of the nose, which can avoid the face mask 8 covering the nose, thus ensuring that the nose can always breathe fresh air.

[0027] In summary, both of the above two embodiments can achieve that after being worn on the head position of the human body, the mask opening 2 is aligned with the mouth position of the human body. When vomiting occurs in the human body, the vomit enters the collection bag 1 through the mask body for centralized collection. When there is more vomit in the collection bag 1, just replace the new collection bag 1.

[0028] Although both of the above two embodiments can be worn on the head position of the human body to align the mask opening 2 with the mouth of the human body, however, compared with the second embodiment, the first embodiment has better stability for the mask opening 2. The headgear of the first embodiment pulls the folding pad 5 through the restraint strap. After the headgear is worn on the head of the human body, it is relatively stable and not easy to slip off. Therefore, even when there is more vomit in the first embodiment, the folding pad 5 is pulled by the gravity of the vomit in the collection bag 1, and it can still maintain a relatively stable position. In the second embodiment, the mask 8 with hanging ear straps 9 on both sides is used as the wearing component 3. Since the ears of the human body are relatively soft, when there is more vomit in the collection bag 1 in the second embodiment, the mask 8 is easily pulled by the gravity of the vomit in the collection bag 1, resulting in the displacement of the mask 8 or the slipping off of the hanging ear straps 9 from the ears, thus causing the mask opening 2 to be unable to align with the mouth. Therefore, compared with the first embodiment, the second embodiment has poorer stability in maintaining the mask opening 2 aligned with the human mouth. However, the structure of the second embodiment is relatively simpler than that of the first embodiment. Each of the two embodiments has its own advantages and disadvantages. Considering that clinical patients often adopt a long-term wearing method during the period when they are prone to vomiting, it is more convenient for the collection of vomit. Therefore, it is better to adopt the method of the first embodiment, and its relative position stability effect on the mask opening 2 is better.
