Description

Parotid gland radiography injection device

Technical Field

The utility model relates to an oral cavity is with injection device, especially a parotid gland radiography injection device.

Background

The parotid gland radiography is an auxiliary imaging technology for X-ray examination after injecting contrast medium through parotid gland duct to display the running and form of parotid duct and the form of parotid gland, and can observe whether the parotid duct is mutated or whether the parotid duct or gland is damaged or broken after trauma.

The parotid gland is a salivary gland secretory organ of a human body and is positioned around an earlobe on the side of the face, and the parotid gland secretes saliva and then is discharged into the oral cavity through a parotid gland duct at a buccal mucosa (an outer side mucosa corresponding to an upper dentition) in the oral cavity; some parotid lesions such as trauma, inflammation, calculus and the like in clinic need parotid gland radiography to observe parotid gland and duct shapes, the current parotid gland radiography technology is to insert a common injector into a parotid duct through an opening of the parotid duct in an oral cavity and inject a contrast medium, the contrast medium overflows after the contrast medium is injected in advance, so that the effect display effect of a contrast image is poor, the common injector cannot be fixed in the oral cavity, an injector pipeline inserted by a doctor before radiography, the injector pipeline is easy to separate due to the involuntary movement of the face of a patient such as swallowing and the like, the radiography fails, and meanwhile, the patient cannot independently complete injection, so that the clinician and the patient are exposed to radioactivity together at present, and the doctor performs X-ray radiography under the continuous contrast medium so as to fully develop the parotid duct and the gland.

In summary, the existing device can inject the contrast agent in advance, but the contrast effect is poor; if the injection is not performed in advance, the patient cannot perform the injection independently, and medical staff needs to be exposed in radioactive rays for auxiliary completion, so that the exposure of the medical staff in the radioactivity is increased; in both cases, the face of the patient can move involuntarily, so that the syringe pipeline is easy to be separated, and the radiography fails.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a parotid gland radiography injection device. The radiography effect is good, the exposure of medical staff in radioactivity is reduced, and meanwhile, the injector pipeline is not easy to separate, and the radiography failure cannot be caused.

The technical scheme of the utility model: the utility model provides a parotid gland radiography injection device, includes fixed soft board, fixed soft board is through connecting soft board joint support board, and the backup pad is connected with thick union coupling through connecting the hard board, the one end of thick pipe is connected with first hose, and the one end of second hose is connected to the other end of thick pipe, and the other end of second hose is connected with the syringe.

In the parotid gland radiography injection device, the joint of the connecting hard plate and the support plate is 0.3cm-0.8cm higher than the joint of the connecting soft plate and the support plate.

In the parotid gland radiography injection device, the joint of the connecting hard plate and the support plate is 0.5cm higher than the joint of the connecting soft plate and the support plate.

In the parotid gland radiography injection device, the other end of the second hose is connected with the injector through a connector.

In the parotid gland radiography injection device, the surface of the fixed soft plate is uneven.

Compared with the prior art, the utility model does not need to inject the contrast agent in advance for refocusing, so that the condition of the overflow of the contrast agent can not occur, and the contrast effect is good; the device is through before the piece is taken a photograph at the X-ray, insert the parotid gland pipe to the first hose of device, bite fixed soft board through the patient interlock and make whole injection device fix in the patient oral cavity, even patient facial activity, also can not make injection device's first hose deviate from the parotid gland pipe mouth yet, then let the patient inject by oneself with the device link to each other be located the oral cavity and be equipped with the syringe of contrast medium outward, thereby reduce the exposure of medical staff in the radioactivity, the syringe pipeline is also difficult to deviate from simultaneously, can not cause the contrast failure.

The labels in the figures are: 1-a first hose, 2-a support plate, 3-a connecting soft board, 4-a fixing soft board, 5-a connecting hard board, 6-a thick pipe, 7-a second hose, 8-an injector and 9-a connector.

Detailed Description

Example 1. An parotid gland radiography injection device comprises figure 1Fig. 3 shows a flexible fixing plate 4, wherein the flexible fixing plate 4 is connected with the supporting plate 2 through a flexible connecting plate 3, the supporting plate 2 is connected with a thick pipe 6 through a rigid connecting plate 5, and the thick pipe 6 is used for fixing the first hose 1 and the second hose 7; one end of the thick tube 6 is connected with a first hose 1, the length of the first hose 1 is about 16cm, and the first hose is used for inserting a parotid duct and is similar to an indwelling needle hose for infusion; the other end of the thick pipe 6 is connected with one end of a second hose 7, and the other end of the second hose 7 is connected with an injector 8; the length of the second hose 7 is about 20cm, and the second hose extends out of the oral cavity and is connected with the injector 8; the joint of the connecting hard board 5 and the supporting board 2 is 0.5cm higher than the joint of the connecting soft board 3 and the supporting board 2; the opening of the parotid duct is 0.5cm higher than the jaw plane, so that the first hose 1 can be conveniently inserted into the parotid duct; the jaw plane is an imaginary plane formed from the mesial adjacent points of the middle incisors on the upper jaw on the two sides to the mesial buccal cusp of the first molar on the two sides; the jaw plane is an abstract line representing the maxillofacial surfaces of the upper and lower jaws when the dental apices are staggered; the other end of the second hose 7 is connected with an injector 8 through a connector 9; uneven lines are arranged on the surface of the fixed soft board 4; the friction is increased to facilitate the occlusion fixation of the teeth; the fixed soft board 4, the connecting soft board 3, the supporting board 2, the connecting hard board 5, the thick pipe 6, the first hose 1 and the second hose 7 are all made of PVC materials, wherein the density of the PVC plastic parts of the fixed soft board 4, the connecting soft board 3, the first hose 1 and the second hose 7 is generally 1.22g/cm³The density of the PVC plastic parts of the supporting plate 2, the connecting hard plate 5 and the thick pipe 6 is generally 1.34g/cm³。
