Description

Technical Field

[0001] The present application relates to the technical field of cell sampling, and in particular to a throat swab sampling device for infectious diseases. Background Art

[0002] Collecting secretions from the pharynx and tonsils for bacterial culture or virus isolation is a commonly used diagnostic method for infectious diseases. Nowadays, pharyngeal swab sampling is often used to complete the above method.

[0003] Some existing throat swab sampling is often completed manually or by a robotic arm. During sampling, the throat swab is clamped by a manual or robotic arm, and the patient is asked to open his mouth wide. Then, the throat swab is controlled to extend into the patient's mouth, and the end of the throat swab is dipped in the secretions on the posterior wall of the patient's pharynx. Then, the throat swab is taken out, and the end of the throat swab is broken in the sampling tube. Finally, the end of the throat swab is immersed in the inactivation liquid in the sampling tube. Through the above actions, the throat swab sampling operation is completed.

[0004] However, in the above process, due to the stimulation of the patient's pharynx by the pharyngeal swab, the patient's mouth is prone to partial closure and coughing, which not only affects the accuracy of the sampling operation, but also causes the sampler or the robotic arm to be contaminated by droplets, thus affecting the subsequent sampling operation. Summary of the invention

[0005] The present application proposes a throat swab sampling device for infectious diseases, which has the advantage of reducing the probability of oral closure and droplet contamination in patients, and is used to solve the problem of sampling operations being affected.

[0006] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: a throat swab sampling device for infectious diseases, comprising: a mounting piece, a support piece is arranged on one side of the mounting piece, the mounting piece and the support piece are both hollow cylindrical structures, there is a distance between the mounting piece and the support piece, a fixing rod is fixedly installed on the side of the support piece facing the mounting piece, a slot is provided inside the mounting piece corresponding to the position of the fixing rod, the end of the fixing rod is plug-in fixed with the slot, a tooth piece is fixedly installed on the outer side of the support piece at equal intervals in the circumferential direction, and the tooth piece is double-layered.

[0007] Furthermore, an extension block is fixedly installed on the upper side of the mounting member, and a gas delivery member No. 1 is arranged above the position between the mounting member and the support member, and the output end of the gas delivery member No. 1 faces the space between the mounting member and the support member, and the gas delivery member No. 1 is fixedly connected to the extension block through a connecting rod.

[0008] Furthermore, two side blocks are fixedly mounted on the side of the support member facing the mounting member, and the two side blocks are distributed on both sides below the No. 1 gas delivery member, and the side of the side block facing the mounting member contacts the mounting member.

[0009] Furthermore, the support member, the locking member and the side stopper are all made of transparent materials.

[0010] Furthermore, a second gas delivery component is fixedly installed inside the mounting component, an annular cavity is opened inside the mounting component, the output end of the second gas delivery component is connected to the annular cavity, the input end of the second gas delivery component is connected to the external environment, and the slot is connected to the annular cavity.

[0011] Furthermore, a guide member is fixedly installed on the lower side of the support member and the lower side of the side stop member, and the guide member consists of an arc plate and two side plates. The arc plate is located below the support member and the side stop member, and side plates are provided on both sides of the arc plate. The lower side of the side plate is fixedly connected to the arc plate, and the upper side of the side plate is fixedly connected to the support member and the side stop member. The left side of the arc plate is inclined upward and contacts the outer side surface of the mounting member.

[0012] Furthermore, the side of the guide member facing away from the mounting member and the support member together form an opening, and a retention member is fixedly installed at the opening, and the retention member is a water-absorbent gauze.

[0013] This application has the following beneficial effects: The present application provides a throat swab sampling device for infectious diseases. The support member and the latch member are arranged to support the patient's oral cavity. At the same time, the latch member is used to fix the relative position of the patient's oral cavity and the support member, so that the patient's oral cavity is not easily closed. In addition, the support member is used to limit the diffusion of the patient's droplets, so that the droplets in the patient's oral cavity can only move from the inside of the support member and then partially adhere to the inner wall of the support member. Through this action, the probability of droplets contaminating the detection personnel or the robotic arm is reduced.

[0014] Through the arrangement of the support member and the No. 1 air supply member, the radial wind generated by the No. 1 air supply member is utilized to close the side of the support member away from the patient, so that when the droplets moving from the inside of the support member and not adhering to the inner wall of the support member move to the end of the support member, they will be blown by the above-mentioned radial wind and move in this direction. Through the above-mentioned action, the probability of droplets contaminating the detection personnel or the robotic arm is further reduced.

[0015] Through the arrangement of the No. 1 air transmission member and the guide member, in the process of the above-mentioned part of the droplets being blown by the radial wind, the droplets will move toward the position of the guide member, thereby causing part of the droplets to adhere to the guide member and the outer wall of the support member. Through this action, the probability of the droplets contaminating the detection personnel or the robotic arm is reduced. At the same time, since the opening of the structure composed of the guide member and the support member is facing away from the detection personnel or the robotic arm, the remaining droplets are not easy to naturally float away and contact the two, thereby reducing the probability of the droplets contaminating the detection personnel or the robotic arm.

[0016] By setting the guide member and the retention member, the retention member is set at the opening of the structure composed of the guide member and the support member, and then comes into contact with the air blown out from that position, so that part of the droplets in the air are intercepted by the retention member, thereby further reducing the probability of droplets contaminating the detection personnel or the robotic arm.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0020] Example 1: Please refer to Figure 1-Figure 5 A throat swab sampling device for infectious diseases comprises a mounting member 1, a support member 2 is arranged on one side of the mounting member 1, both the mounting member 1 and the support member 2 are hollow cylindrical structures, there is a distance between the mounting member 1 and the support member 2, a fixing rod 3 is fixedly installed on the side of the support member 2 facing the mounting member 1, a slot 4 is opened inside the mounting member 1 at the position corresponding to the fixing rod 3, the end of the fixing rod 3 is plugged and fixed with the slot 4, and a tooth member 5 is fixedly installed on the outer side of the support member 2 at equal intervals in the circumferential direction, and the tooth member 5 is a double-layer arrangement.

[0021] When in use, the fixing rod 3 is inserted into the slot 4 so that the mounting member 1 and the supporting member 2 are fixed together. Then, the supporting member 2 is placed in the patient's oral cavity, and the patient's teeth are engaged between the double-layered latching members 5. Then, the testing personnel or the robotic arm drives the pharyngeal swab through the mounting member 1 and the supporting member 2, and then contacts and dips the secretions of the patient's posterior pharyngeal wall. Finally, the pharyngeal swab is taken out, and the end of the pharyngeal swab is broken in the sampling tube, and finally the end of the pharyngeal swab is immersed in the inactivation liquid in the sampling tube. In the above actions, the supporting member 2 is used to support the patient's oral cavity, and the latching member 5 is used to fix the pharyngeal swab. The relative position of the patient's mouth and the support 2 makes it less likely for the patient to have problems with oral closure and support 2 falling out. In addition, the support 2 limits the diffusion of the patient's droplets, so that the droplets in the patient's mouth can only move from the inside of the support 2 and then partially adhere to the inner wall of the support 2. Through this action, the probability of droplets contaminating the detection personnel or the robotic arm is reduced. Finally, when the throat swab sampling is completed, the patient no longer bites the support 2, and the fixing rod 3 is separated from the slot 4, the used support 2 and its connecting parts are discarded, and a new support 2 and its connecting parts are replaced.

[0022] See also Figure 1-Figure 5 An extension block 6 is fixedly installed on the upper side of the mounting member 1, and a gas delivery member 7 (such as a gas delivery mechanism, an air pump in the prior art) is arranged above the position between the mounting member 1 and the support member 2. The output end of the gas delivery member 7 faces the space between the mounting member 1 and the support member 2, and the gas delivery member 7 is fixedly connected to the extension block 6 through a connecting rod.

[0023] During the process of the patient biting the support member 2, the No. 1 air supply member 7 outputs radial wind to the space between the mounting member 1 and the support member 2. Since the radial wind closes the side of the support member 2 away from the patient, the droplets moving from the inside of the support member 2 and not adhering to the inner wall of the support member 2 will be blown by the radial wind when they move to the end of the support member 2, and then move in this direction. Through the above action, the probability of droplets contaminating the detection personnel or the robotic arm is further reduced.

[0024] See also Figure 1-Figure 5 Two side blocks 8 are fixedly installed on the side of the support member 2 facing the mounting member 1. The two side blocks 8 are distributed on both sides below the first gas delivery member 7. The side blocks 8 contact the mounting member 1 on the side facing the mounting member 1.

[0025] The flow of the radial wind is limited by the side baffles 8 so that it can only flow downward, thereby reducing the probability of the droplets flying out of the support member 2 to naturally disperse and contact the detection personnel or the robot arm.

[0026] See also Figure 1-Figure 5 The support member 2, the latch member 5 and the side stop member 8 are all made of transparent materials.

[0027] By setting the above materials, light can enter the inner side of the support 2, so that the inspector can clearly observe the patient's pharynx.

[0028] See also Figure 1-Figure 5 A second gas delivery component 9 is fixedly installed inside the mounting component 1, and an annular cavity 10 is opened inside the mounting component 1. The output end of the second gas delivery component 9 is connected to the annular cavity 10, the input end of the second gas delivery component 9 is connected to the external environment, and the slot 4 is connected to the annular cavity 10.

[0029] When the fixed rod 3 is plugged into the slot 4, the No. 2 air delivery component 9 draws air from the annular cavity 10 and the slot 4, causing the fixed rod 3 to be tightly connected to the slot 4, so that the above work can be carried out smoothly. Afterwards, when the patient's sampling is completed, the No. 2 air delivery component 9 delivers air to the annular cavity 10 and the slot 4, thereby pushing the fixed rod 3 to leave the slot 4, so that the detection personnel or the robotic arm will not come into contact with the used support member 2 and its connecting parts, thereby avoiding contamination of the detection personnel or the robotic arm.

[0030] Example 2: Please refer to Figure 1-Figure 5 This embodiment is a further improvement of the first embodiment, and the improvement lies in that a guide member 11 is fixedly installed on the lower side of the support member 2 and the lower side of the side stopper 8. The guide member 11 consists of an arc plate 110 and two side plates 111. The arc plate 110 is located below the support member 2 and the side stopper 8. Side plates 111 are arranged on both sides of the arc plate 110. The lower side of the side plate 111 is fixedly connected to the arc plate 110, and the upper side of the side plate 111 is fixedly connected to the support member 2 and the side stopper 8. The left side of the arc plate 110 is inclined upward and contacts the outer side surface of the mounting member 1.

[0031] In the process that the above-mentioned part of the droplets are blown by the radial wind, the droplets will move toward the position of the guide member 11, thereby causing part of the droplets to adhere to the arc plate 110, the side plate 111 and the outer wall of the support member 2. Through this action, the probability of the droplets contaminating the detection personnel or the robotic arm is reduced. At the same time, since the opening of the structure composed of the guide member 11 and the support member 2 is facing away from the detection personnel or the robotic arm, the remaining droplets are not easy to naturally float and contact the two, thereby reducing the probability of the droplets contaminating the detection personnel or the robotic arm.

[0032] See also Figure 1-Figure 5 The guide member 11 and the support member 2 together form an opening on one side facing away from the mounting member 1, and a retention member 12 is fixedly installed at the opening, and the retention member 12 is a water-absorbing gauze.

[0033] The retention member 12 is arranged at the opening of the structure formed by the guide member 11 and the support member 2, so as to come into contact with the air blown out from that position, so that part of the droplets in the air are intercepted by the retention member 12, thereby further reducing the probability of the droplets contaminating the detection personnel or the robot arm.
